information that you should consider before deciding to invest in our securities. You should read this entire prospectus and the accompanying prospectus carefully, including the &#147;Risk Factors&#148; section contained in this prospectus and our
consolidated financial statements and the related notes and the other documents incorporated by reference into this prospectus and in the accompanying prospectus. Unless we have indicated otherwise or the context otherwise requires, references in

<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Business Overview </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We are a
biopharmaceutical company engaged in the discovery, acquisition, development and commercialization of proprietary drug therapeutics for addressing significant unmet medical needs in the U.S., Europe and additional international markets. Our primary
therapeutic focus is oncology, including the treatment of chronic cancer pain, but we are also developing therapeutic products for other indications, including immunology and infectious diseases. We currently have two clinical development programs
underway: (i)&nbsp;our lead oncology drug product candidate Cynviloq&#153;, a micellar diblock copolymeric paclitaxel formulation, and (ii)&nbsp;resiniferatoxin, a non-opiate, ultra potent and selective agonist of the TRPV-1 receptor for intractable
pain in end-stage disease. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our pipeline also includes preclinical fully human therapeutic antibodies, including our fully human
anti-PD-L1 and anti-PD-1 monoclonal antibodies, or Abs, derived from our proprietary G-MAB<SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP> library platform, antibody drug conjugates, or ADCs, and recombinant intravenous immunoglobulin, or
rIVIG. Our objective is to develop two classes of antibody drug products, therapeutic antibodies and ADCs: (i)&nbsp;First in Class, or FIC, and/or (ii)&nbsp;Best in Class, or BIC, which may offer greater efficacy and/or fewer adverse events or side
effects as compared to existing drugs. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Although we intend to retain ownership and control of some product candidates by advancing their
development, we will also consider partnerships with pharmaceutical or biopharmaceutical companies in order to balance the risks associated with drug discovery and development and maximize our stockholders&#146; returns. Our partnering objectives
include generating revenue through license fees, milestone-related development fees and royalties by licensing rights to our product candidates. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our goal is to deliver innovative, highly effective and safe treatment options to patients throughout the world. By working closely with
scientists, doctors, patient organizations and other health care specialists, we are committed to improving the lives of patients and assisting their caregivers in their fight against serious diseases. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Recent Developments </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On March&nbsp;31,
2014, we announced that the first patient has been dosed in the pivotal clinical trial designed to support Cynviloq for the treatment of metastatic breast cancer and non-small cell lung cancer. The registration trial is an open-label, randomized,
multi-center, single-dose, crossover registration study being conducted at clinical sites across the U.S., EU, and Singapore. A projected 100 patients with metastatic or locally recurrent breast cancer will be administered 260 mg/m<SUP
STYLE="font-size:85%; vertical-align:top">2</SUP> of Cynviloq or 260 mg/m<SUP STYLE="font-size:85%; vertical-align:top">2</SUP> of Abraxane<SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP> using a 30 minute infusion in a crossover design to
compare the bioequivalence of both drugs. Based on the End-of-Phase II meeting with the U.S. Food and Drug Administration, or FDA, in July 2013, this trial was designed to gain marketing approval for Cynviloq under the 505(b)(2) regulatory pathway
in the U.S. We expect to file a New Drug Application with the FDA in the first half of 2015.</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On March&nbsp;31, 2014, we entered into an
amended and restated loan and security agreement with Oxford Finance LLC and Silicon Valley Bank, increasing the September 2013 facility from $5,000,000 to $12,500,000, with two banks. The amended and restated loan bears interest at 7.95%&nbsp;per
annum. We will make interest only payments on the outstanding amount of the loan on a monthly basis until October&nbsp;1, 2014, after which equal monthly payments of principal and interest are due until the loan maturity date of September&nbsp;30,
2017. In the event we raise $30 million of net equity or proceeds from a collaboration, if any, the interest only period will be extended by six months. Such loan is secured by a security interest in substantially all of our assets, excluding
intellectual property, which is subject to a negative pledge. In connection with the amended and restated loan and security agreement, the Lenders received a warrant to purchase an aggregate 34,642 shares of our common stock at an exercise price of
$12.99 per share, which is exercisable for seven years from the date of issuance. </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>You should carefully consider the risks described below before making an investment decision. The risks described below are not the only ones we face.
Additional risks we are not presently aware of or that we currently believe are immaterial may also impair our business operations. Our business could be harmed by any of these risks. The trading price of our common stock could decline due to any of
these risks, and you may lose all or part of your investment. In assessing these risks, you should also refer to the other information contained or incorporated by reference into this prospectus, including our financial statements and related notes.
</I></P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks Related to Our Financial Position and Capital Requirements </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>We are a development-stage company subject to all of the risks and uncertainties of a new business, including the risk that we or our partners may never
develop, complete development or market any of our product candidates or generate product related revenues. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We are a
development-stage biopharmaceutical company that began operating and commenced research and development activities in 2009. Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. There is
no assurance that our libraries of fully-human mAbs will be suitable for diagnostic or therapeutic use, or that we will be able to identify and isolate therapeutics product candidates, or develop, market and commercialize these candidates. We do not
expect any of our fully-human mAb, ADC, RTX, Cynviloq or related companion diagnostic product candidates to be commercially available for a few years, if at all. Even if we are able to commercialize our product candidates, there is no assurance that
these candidates would generate revenues or that any revenues generated would be sufficient for us to become profitable or thereafter maintain profitability. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>We do not have any products that are approved for commercial sale and therefore do not expect to generate any revenues from product sales in the
foreseeable future, if ever. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We have not generated any product related revenues to date, and do not expect to generate any such
revenues for at least the next several years, if at all. To obtain revenues from sales of our product candidates, we must succeed, either alone or with third parties, in developing, obtaining regulatory approval for, manufacturing and marketing
products with commercial potential. We may never succeed in these activities, and we may not generate sufficient revenues to continue our business operations or achieve profitability. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>We have incurred significant losses since inception and anticipate that we will incur continued losses for the foreseeable future. </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As of December&nbsp;31, 2013 and 2012, we had an accumulated deficit of $32.9 million and $11.0 million, respectively. We have incurred
operating losses since our inception, expect to continue to incur significant operating losses for the foreseeable future, and we expect these losses to increase as we: (i)&nbsp;conduct our BE registration trial related to Cynviloq and prepare for

continue to develop our technology, identify product candidates, develop and commercialize any product candidates we are able to identify and enter into successful collaborative arrangements with other companies, as well as for you to assess the
advisability of investing in our securities. Each of these requirements will require substantial time, effort and financial resources. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Each of our product candidates will require additional preclinical or clinical development, management of preclinical, clinical and
manufacturing activities, regulatory approval in multiple jurisdictions, obtaining manufacturing supply, building of a commercial organization, and significant marketing efforts before we generate any revenues from product sales. We are not
permitted to market or promote any of our product candidates before we receive regulatory approval from the U.S. Food and Drug Administration, or FDA, or comparable foreign regulatory authorities, and we may never receive such regulatory approval
for any of our product candidates. In addition, our product development programs contemplate the development of companion diagnostics by our third-party collaborators. Companion diagnostics are subject to regulation as medical devices and must
themselves be approved for marketing by the FDA or certain other foreign regulatory agencies before we may commercialize our product candidates. </P>

inherently uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials.
Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. It is not uncommon for companies in the
biopharmaceutical industry to suffer significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. Our future clinical trial results may not be successful.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">This drug candidate development risk is heightened by any changes in the planned clinical trials compared to the completed clinical
trials. As product candidates are developed through preclinical to early and late stage clinical trials towards approval and commercialization, it is customary that various aspects of the development program, such as manufacturing and methods of
administration, are altered along the way in an effort to optimize processes and results. While these types of changes are common and are intended to optimize the product candidates for late stage clinical trials, approval and commercialization,
such changes do carry the risk that they will not achieve these intended objectives. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We have not previously initiated or completed a
corporate-sponsored clinical trial. Consequently, we may not have the necessary capabilities, including adequate staffing, to successfully manage the execution and completion of any clinical trials we initiate, including our planned clinical trials
of Cynviloq and RTX, in a way that leads to our obtaining marketing approval for our product candidates in a timely manner, or at all. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In
the event we are able to conduct a pivotal clinical trial of a product candidate, the results of such trial may not be adequate to support marketing approval. Because our product candidates are intended for use in life-threatening diseases, in some
cases we ultimately intend to seek marketing approval for each product candidate based on the results of a single pivotal clinical trial. As a result, these trials may receive enhanced scrutiny from the FDA. For any such pivotal trial, if the FDA
disagrees with our choice of primary endpoint or the results for the primary endpoint are not robust or significant relative to control, are subject to confounding factors, or are not adequately supported by other study endpoints, including possibly
overall survival or complete response rate, the FDA may refuse to approve a BLA based on such pivotal trial. The FDA may require additional clinical trials as a condition for approving our product candidates. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In some of our future trials, we may combine Cynviloq with other therapies such as chemotherapy or immunotherapy. We have not yet tested these

down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition,

As a result, we must compete with them for clinical sites, physicians and the limited number of patients who fulfill the stringent requirements for participation in clinical trials. Also, due to the confidential nature of clinical trials, we do not
know how many of the eligible patients may be enrolled in competing studies and who are consequently not available to us for our clinical trials. Our clinical trials may be delayed or terminated due to the inability to enroll enough patients.
Patient enrollment depends on many factors, including the size of the patient population, the nature of the trial protocol, the proximity of patients to clinical sites and the eligibility criteria for the study. The delay or inability to meet
planned patient enrollment may result in increased costs and delays or termination of the trial, which could have a harmful effect on our ability to develop products. </P>

Drug Products with Therapeutics Equivalence Evaluations,&#148; or the Orange Book, for certain of these referenced products. In the event that one or more patents is listed in the Orange Book for the referenced product after our submission of
additional information in support of our NDA for Cynviloq, we may also be required to evaluate the applicability of these patents to&nbsp;Cynviloq&nbsp;and submit additional certifications. A paragraph III certification, stating that a listed patent
has not expired, but will expire on a particular date, may delay the approval of&nbsp;Cynviloq&nbsp;until the expiration of the patent. A paragraph IV certification, stating that a listed patent is invalid, unenforceable, or not infringed
by&nbsp;Cynviloq&nbsp;may require us to notify the patent owner and the holder of the NDA for the referenced product of the existence of the Cynviloq&nbsp;NDA, and may result in patent litigation against us and the entry of a 30-month stay of FDA

marketing exclusivity in connection with any approval of our NDA for&nbsp;Cynviloq. Such exclusivity protection would preclude the FDA from approving a marketing application for a duplicate of&nbsp;Cynviloq, a product candidate that the FDA views as
having the same conditions of approval as&nbsp;Cynviloq&nbsp;(for example, the same indication, the same route of delivery and/or other conditions of use), or a 505(b)(2) NDA submitted to the FDA with&nbsp;Cynviloq&nbsp;as the reference product, for
a period of three years from the date of&nbsp;Cynviloq&nbsp;approval, although the FDA may accept and commence review of such applications. This form of exclusivity may not prevent FDA approval of an NDA that relies only on its own data to support
the change or innovation. Similarly, if, prior to approval of the&nbsp;Cynviloq&nbsp;NDA, another company obtains approval for a product candidate under, in the view of the FDA, the same conditions of approval that we are seeking
for&nbsp;Cynviloq,&nbsp;Cynviloq could be blocked until the other company&#146;s three-year Hatch-Waxman marketing exclusivity expires. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Our

and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities. To date, patients treated with Cynviloq have experienced drug-related side effects such as neutropenia,
leukopenia, anemia, thrombocytopenia, peripheral neuropathy, myalgia nausea, vomiting, diarrhea, alopecia, rash, pruritus and hypersensitivity reactions. The clinical evaluation of Cynviloq is still in the early stages, but as is the case with all
oncology drugs, it is likely that there may be side effects associated with its use. Results of our trials could reveal a high and unacceptable severity and prevalence of these or other side effects. In such an event, our trials could be suspended
or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. The drug-related side effects could affect patient

receive less revenue than if we sold our products directly. In addition, although we would intend to use due diligence in monitoring their activities, we may have little or no control over the sales efforts of those third parties. In the event we

third party, we may not be able to enter into any marketing arrangements on favorable terms or at all. In addition, these arrangements could result in lower levels of income to us than if we marketed our product candidates entirely on our own. If we
are unable to enter into a marketing arrangement for our product candidates in international markets, we may not be able to develop an effective international sales force to successfully commercialize those products in international markets. If we

believe the name inappropriately implies medical claims. If the FDA objects to any of our proposed product brand names, we may be required to adopt an alternative brand name for our product candidates. If we adopt an alternative brand name, we would
lose the benefit of our existing trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a suitable product brand name that would qualify under applicable trademark

of Abraxane when the patents covering it begin to expire in approximately 2022, or earlier if the patents are successfully challenged. If we are unable to demonstrate to physicians and payers that the key differentiating features of Cynviloq

market our product candidates in the U.S., Europe and other selected foreign jurisdictions. Market acceptance and sales of our product candidates in both domestic and international markets will depend significantly on the availability of adequate
coverage and reimbursement from third-party payors for any of our product candidates and may be affected by existing and future health care reform measures. Government and other third-party payors are increasingly attempting to contain healthcare
costs by limiting both coverage and the level of reimbursement for new drugs and, as a result, they may not cover or provide adequate payment for our product candidates. These payors may conclude that our product candidates are less safe, less
effective or less cost-effective than existing or future introduced products, and third-party payors may not approve our product candidates for coverage and reimbursement or may cease providing coverage and reimbursement for these product

In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product candidate. To obtain reimbursement or pricing approval in some countries, we may be required to
conduct additional clinical trials that compare the cost-effectiveness of our product candidates to other available therapies. If reimbursement of our product candidates is unavailable or limited in scope or amount in a particular country, or if

jurisdictions, there have been and we expect there will continue to be a number of legislative and regulatory changes to the health care system that could impact our ability to sell our products profitably. The U.S. government and other governments
have shown significant interest in pursuing healthcare reform. In particular, the Medicare Modernization Act of 2003 revised the payment methodology for many products under the Medicare program in the U.S. This has resulted in lower rates of
reimbursement. In 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, collectively, the Healthcare Reform Law, was enacted. The Healthcare Reform Law substantially changes the way
healthcare is financed by both governmental and private insurers. Such government-adopted reform measures may adversely impact the pricing of healthcare products and services in the U.S. or internationally and the amount of reimbursement available

Companion diagnostics are subject to regulation by the FDA and comparable foreign regulatory authorities as medical devices and require separate regulatory approval prior to commercialization. We do not develop companion diagnostics internally and
thus we are dependent on the sustained cooperation and effort of our third-party collaborators in developing and obtaining approval for these companion diagnostics. We and our collaborators may encounter difficulties in developing and obtaining
approval for the companion diagnostics, including issues relating to selectivity/specificity, analytical validation, reproducibility, or clinical validation. Any delay or failure by our collaborators to develop or obtain regulatory approval of the
companion diagnostics could delay or prevent approval of our product candidates. In addition, our collaborators may encounter production difficulties that could constrain the supply of the companion diagnostics, and both they and we may have
difficulties gaining acceptance of the use of the companion diagnostics in the clinical community. If such companion diagnostics fail to gain market acceptance, it would have an adverse effect on our ability to derive revenues from sales of our
products. In addition, the diagnostic company with whom we contract may decide to discontinue selling or manufacturing the companion diagnostic that we anticipate using in connection with development and commercialization of our product candidates
or our relationship with such diagnostic company may otherwise terminate. We may not be able to enter into arrangements with another diagnostic company to obtain supplies of an alternative diagnostic test for use in connection with the development

that is personal in nature. The maintenance of this data is subject to certain privacy-related laws, which impose upon us administrative and financial burdens, and litigation risks. For instance, the rules promulgated by the Department of Health and
Human Services under the Health Insurance Portability and Accountability Act, or HIPAA, create national standards to protect patients&#146; medical records and other personal information in the U.S. These rules require that healthcare providers and
other covered entities obtain written authorizations from patients prior to disclosing protected health care information of the patient to companies. If the patient fails to execute an authorization or the authorization fails to contain all required
provisions, then we will not be allowed access to the patient&#146;s information and our research efforts can be substantially delayed. Furthermore, use of protected health information that is provided to us pursuant to a valid patient authorization
is subject to the limits set forth in the authorization (i.e., for use in research and in submissions to regulatory authorities for product approvals). As such, we are required to implement policies, procedures and reasonable and appropriate
security measures to protect individually identifiable health information we receive from covered entities, and to ensure such information is used only as authorized by the patient. Any violations of these rules by us could subject us to civil and
criminal penalties and adverse publicity, and could harm our ability to initiate and complete clinical studies required to support regulatory applications for our proposed products. In addition, HIPAA does not replace federal, state, or other laws
that may grant individuals even greater privacy protections. We can provide no assurance that future legislation will not prevent us from generating or maintaining personal data or that patients will consent to the use of their personal information,
either of which may prevent us from undertaking or publishing essential research. These burdens or risks may prove too great for us to reasonably bear, and may adversely affect our ability to achieve profitability or maintain profitably in the

an abbreviated pathway for the approval of biosimilar and interchangeable biological products was created. The new abbreviated regulatory pathway establishes legal authority for the FDA to review and approve biosimilar biologics, including the
possible designation of a biosimilar as &#147;interchangeable.&#148; The FDA defines an interchangeable biosimilar as a product that, in terms of safety or diminished efficacy, presents no greater risk when switching between the biosimilar and its
reference product than the risk of using the reference product alone. Under the BPCIA, an application for a biosimilar product cannot be submitted to the FDA until four years, or approved by the FDA until 12&nbsp;years, after the original brand
product identified as the reference product was approved under a BLA. The new law is complex and is only beginning to be interpreted by the FDA. As a result, its ultimate impact, implementation and meaning are subject to uncertainty. While it is
uncertain when any such processes may be fully adopted by the FDA, any such processes could have a material adverse effect on the future commercial prospects for our biological products. </P>

a BLA, such approved products should qualify for the 12-year period of exclusivity. However, there is a risk that the U. S. Congress could amend the BPCIA to significantly shorten this exclusivity period as proposed by President Obama, potentially
creating the opportunity for generic competition sooner than anticipated. Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of our reference products in a way that is similar to traditional generic
substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing. In addition, a competitor could decide to forego the biosimilar route and submit a full BLA after
completing its own preclinical studies and clinical trials. In such cases, any exclusivity to which we may be eligible under the BPCIA would not prevent the competitor from marketing its product as soon as it is approved. </P>

event of such an accident, we could be held liable for any resulting damages and any liability could materially adversely affect our business, financial condition and results of operations. We do not currently maintain hazardous materials insurance

depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level, and senior managers as well as junior, mid-level, and senior scientific and medical personnel. The loss of any of our executive officers, key
employees or key consultants and our inability to find suitable replacements could impede the achievement of our research and development objectives, potentially harm our business, financial condition and prospects. Furthermore, recruiting and
retaining qualified scientific personnel to perform research and development work in the future is critical to our success. We may be unable to attract and retain personnel on acceptable terms given the competition among biotechnology,
biopharmaceutical and health care companies, universities and non-profit research institutions for experienced scientists. Certain of our current officers, directors, scientific advisors and/or consultants or certain of the officers, directors,
scientific advisors and/or consultants hereafter appointed may from time to time serve as officers, directors, scientific advisors and/or consultants of other biopharmaceutical or biotechnology companies. We do not maintain &#147;key man&#148;

different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than
what we have to offer. If we are unable to continue to attract and retain high quality personnel, the rate and success at which we can develop and commercialize product candidates will be limited. </P>

and Silicon Valley Bank, or SVB, that is secured by a lien covering substantially all of our assets, excluding intellectual property. As of December&nbsp;31, 2013, under our initial $5.0&nbsp;million loan and security agreement with Oxford and SVB
entered into in September 2013, we had an outstanding principal balance of $5.0&nbsp;million. The amended and restated loan and security agreement contains customary affirmative and negative covenants and events of default. The affirmative covenants
include, among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports and maintain insurance coverage. The negative covenants include, among others, restrictions on transferring
collateral, changing our business, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments and creating other liens on our assets, in each case subject to customary
exceptions. If we default under the loan agreement, the lenders may accelerate all of our repayment obligations and take control of our pledged assets, potentially requiring us to renegotiate our agreement on terms less favorable to us or to
immediately cease operations. Further, if we are liquidated, the lender&#146;s right to repayment would be senior to the rights of the holders of our common stock to receive any proceeds from the liquidation. The lenders could declare a default upon
the occurrence of any event that they interpret as a material adverse change as defined under the loan agreement, thereby requiring us to repay the loan immediately or to attempt to reverse the declaration of default through negotiation or
litigation. Any declaration by the lenders of an event of default could significantly harm our business and prospects and could cause the price of our common stock to decline. If we raise any additional debt financing, the terms of such additional

depend in part on our ability to obtain and maintain patent protection for our product candidates, methods, processes and other technologies, to prevent third parties from infringing on our proprietary rights and to operate without infringing upon
the proprietary rights of third parties. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary rights are covered by valid and enforceable patents or are effectively
maintained as trade secrets. We attempt to protect our proprietary position by maintaining trade secrets and by filing U.S. and foreign patent applications related to our proprietary technology, inventions and improvements that are important to the
development of our business. We have one issued U.S. patent covering our G-MAB<SUP STYLE="font-size:85%; vertical-align:top">&reg;</SUP> which expires in 2022 and the examination of its European equivalent is currently in progress. In 2011, several
improvement patent applications were filed for our proprietary antibody library technology. In 2013, we filed 14 antibody family patents. In 2013, we filed three patent application families for the Concortis conjugation chemistry. However, due to
the difficulties of enforcing such antibody library technology, we filed a key patent application in the U.S. only and requested nonpublication. We have commenced generating a patent application portfolio of patents to protect each product candidate
in our pipeline. However, the patent position of biopharmaceutical companies involves complex legal and factual questions, and therefore we cannot predict with certainty whether any patent applications that we have filed or that we may file in the
future will be approved or any resulting patents will be enforced. In addition, third parties may challenge, seek to invalidate or circumvent any of our patents, once they are issued. Thus, any patents that we own or license from third parties may
not provide any protection against competitors. Any patent applications that we have filed or that we may file in the future, or those we may license from third parties, may not result in patents being issued. Also, patent rights may not provide us
with adequate proprietary protection or competitive advantages against competitors with similar technologies. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In addition, the laws of
certain foreign countries do not protect our intellectual property rights to the same extent as do the laws of the U.S. If we fail to apply for intellectual property protection or if we cannot adequately protect our intellectual property rights in
these foreign countries, our competitors may be able to compete more effectively against us, which could adversely affect our competitive position, as well as our business, financial condition and results of operations. </P>

Act, to invalidate potentially overly-broad third party rights. Even if we are able to defend our position, the cost of doing so may adversely affect our ability to grow, generate revenue or become profitable. Although we have not yet experienced
patent litigation, we may in the future be subject to such litigation and may not be able to protect our intellectual property at a reasonable cost, or at all, if such litigation is initiated. The outcome of litigation is always uncertain, and in

third parties. There is a substantial amount of litigation involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including Patent Office administrative proceedings, such as inter parties reviews,
and reexamination proceedings before the U.S.&nbsp;PTO or oppositions and revocations and other comparable proceedings in foreign jurisdictions. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third
parties, exist in the fields in which we are developing product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates may give rise to claims of infringement
of the patent rights of others. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Despite safe harbor provisions, third parties may assert that we are employing their proprietary
technology without authorization. There may be third-party patents, of which we are currently unaware, with claims to materials, formulations, methods of doing research or library screening, methods of manufacture or methods for treatment related to
the use or manufacture of our product candidates. Because patent applications can take many years to issue, there may be currently pending patent published applications which may later result in issued patents that our product candidates may
infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process
of any of our product candidates, any molecules formed during the manufacturing process or any final product itself, the holders of any such patents may be able to block our ability to commercialize such product candidate unless we obtain a license
under the applicable patents, or until such patents expire or they are finally determined to be held invalid or unenforceable. Similarly, if any third-party patent were held by a court of competent jurisdiction to cover aspects of our formulations,
processes for manufacture or methods of use, including combination therapy or patient selection methods, the holders of any such patent may be able to block our ability to develop and commercialize the applicable product candidate unless we obtain a
license, limit our uses, or until such patent expires or is finally determined to be held invalid or unenforceable. In either case, such a license may not be available on commercially reasonable terms or at all. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop
and commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a
successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys&#146; fees for willful infringement, obtain one or more licenses from third parties, limit our uses, pay royalties or
redesign our infringing product candidates, which may be impossible or require substantial time and monetary expenditure. We cannot predict whether any such license would be available at all or whether it would be available on commercially
reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our product candidates. We may fail to obtain any of these licenses at a
reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our product candidates, which could harm our business significantly. </P>

may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as
strong as that in the U.S. These products may compete with our products in jurisdictions where we do not have any issued patents and our patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so
competing. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign
jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biopharmaceuticals, which could make
it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and
divert our efforts and attention from other aspects of our business. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Confidentiality agreements with employees and others may not adequately

employees, consultants, outside scientific collaborators, sponsored researchers and other advisors, to protect our trade secrets and unpatented know-how. These agreements generally require that the other party keep confidential and not disclose to
third parties all confidential information developed by the party or made known to the party by us during the course of the party&#146;s relationship with us. We also typically obtain agreements from these parties which provide that inventions
conceived by the party in the course of rendering services to us will be our exclusive property. However, these agreements may not be honored and may not effectively assign intellectual property rights to us. Enforcing a claim that a party illegally
obtained and is using our trade secrets or know-how is difficult, expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the U.S. may be less willing to protect trade secrets or know-how. The failure to obtain or

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If we raise additional funds through collaboration, licensing or other similar arrangements, it
may be necessary to relinquish potentially valuable rights to our product candidates, potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. If adequate funds are not available, our ability to
achieve profitability or to respond to competitive pressures would be significantly limited and we may be required to delay, significantly curtail or eliminate the development of our product candidates. </P>

directors, executive officers and principal stockholders beneficially owned, in the aggregate, approximately 36.7% of our outstanding voting securities. As a result, if some or all of them acted together, they would have the ability to exert
substantial influence over the election of our board of directors and the outcome of issues requiring approval by our stockholders. This concentration of ownership may also have the effect of delaying or preventing a change in control of our company
that may be favored by other stockholders. This could prevent transactions in which stockholders might otherwise recover a premium for their shares over current market prices. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Our ability to use our net operating loss carry forwards may be subject to limitation. </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Generally, a change of more than 50% in the ownership of a company&#146;s stock, by value, over a three-year period constitutes an ownership
change for U.S. federal income tax purposes. An ownership change may limit our ability to use our net operating loss carryforwards attributable to the period prior to the change. As a result, if we earn net taxable income, our ability to use our
pre-change net operating loss carryforwards to offset U.S. federal taxable income may become subject to limitations, which could potentially result in increased future tax liability for us. At December&nbsp;31, 2013, we had net operating loss
carryforwards aggregating approximately $28.1&nbsp;million. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Our certificate of incorporation, as amended, and bylaws provide for indemnification of

</I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our certificate of incorporation, as amended, bylaws and applicable Delaware law provide for the indemnification of our directors,
officers, employees, and agents, under certain circumstances, against attorney&#146;s fees and other expenses incurred by them in any litigation to which they become a party arising from their association with or activities on our behalf. We will
also bear the expenses of such litigation for any of our directors, officers, employees, or agents, upon such person&#146;s promise to repay us, therefore if it is ultimately determined that any such person shall not have been entitled to
indemnification. This indemnification policy could result in substantial expenditures by us, which we will be unable to recover. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Our corporate

that our stockholders may consider favorable. For example, our certificate of incorporation, as amended, authorizes our board of directors to issue up to 100,000,000 shares of &#147;blank check&#148; preferred stock. As a result, without further
stockholder approval, the board of directors has the authority to attach special rights, including voting and dividend rights, to this preferred stock. With these rights, preferred stockholders could make it more difficult for a third party to
acquire us. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We are also subject to the anti-takeover provisions of the Delaware General Corporation Law. Under these provisions, if
anyone becomes an &#147;interested stockholder,&#148; we may not enter into a &#147;business combination&#148; with that person for three years without special approval, which could discourage a third party from making a takeover offer and could
delay or prevent a change in control of us. An &#147;interested stockholder&#148; means, generally, someone owning 15% or more of our outstanding voting stock or an affiliate of ours that owned 15% or more of our outstanding voting stock during the
past three years, subject to certain exceptions as described in the Delaware General Corporation Law. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We have adopted a shareholder
rights plan, the purpose of which is, among other things, to enhance our board&#146;s ability to protect shareholder interests and to ensure that shareholders receive fair treatment in the event any coercive takeover attempt of our company is made
in the future.&nbsp;The shareholder rights plan could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, our company or a large block of our common stock. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Compliance with changing regulations concerning corporate governance and public disclosure may result in
additional expenses. </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">There have been changing laws, regulations and standards relating to corporate governance and public
disclosure, including the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley, new regulations promulgated by the SEC and rules promulgated by the national securities
exchanges. The Dodd-Frank Act, enacted in July 2010, expands federal regulation of corporate governance matters and imposes requirements on public companies to, among other things, provide stockholders with a periodic advisory vote on executive
compensation and also adds compensation committee reforms and enhanced pay-for-performance disclosures. While some provisions of the Dodd-Frank Act are effective upon enactment, others will be implemented upon the SEC&#146;s adoption of related
rules and regulations. The scope and timing of the adoption of such rules and regulations is uncertain and, accordingly, the cost of compliance with the Dodd-Frank Act is also uncertain. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">These new or changed laws, regulations and standards are, or will be, subject to varying interpretations in many cases due to their lack of
specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated
by ongoing revisions to disclosure and governance practices. As a result, our efforts to comply with evolving laws, regulations and standards are likely to continue to result in increased general and administrative expenses and a diversion of
management time and attention from revenue-generating activities to compliance activities. Members of our board of directors and our principal executive officer and principal financial officer could face an increased risk of personal liability in
connection with the performance of their duties. As a result, we may have difficulty attracting and retaining qualified directors and executive officers, which could harm our business. If the actions we take in our efforts to comply with new or
changed laws, regulations and standards differ from the actions intended by regulatory or governing bodies, we could be subject to liability under applicable laws or our reputation may be harmed. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>If we fail to comply with the rules&nbsp;under the Sarbanes-Oxley Act of 2002 related to accounting controls and procedures, or, if we discover material
weaknesses and deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult. </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Sarbanes-Oxley specifically requires, among other things, that we maintain effective internal controls for financial reporting and disclosure
of controls and procedures. In particular, we must perform system and process evaluation and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial
reporting, as required by Section&nbsp;404 of Sarbanes-Oxley. Our testing, or the subsequent testing by our independent registered public accounting firm, if and when required, may reveal deficiencies in our internal controls over financial
reporting that are deemed to be material weaknesses. Our compliance with Section&nbsp;404 will require that we incur substantial accounting expense and expend significant management efforts. We currently do not have an internal audit group, and we
will need to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge. Moreover, if we are not able to comply with the requirements of Section&nbsp;404 in a timely manner, or if we
or our independent registered public accounting firm identifies deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline, and we could be subject to
sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources. </P>

threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director, officer or agent of the corporation

and reasonably incurred in connection with such action, suit or proceeding if the person indemnified acted in good faith and in a manner he or she reasonably believed to be in or not opposed to, the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. In the case of an action by or in the right of the corporation, no indemnification may be made with respect to any claim, issue or
matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine that despite the adjudication of

PROSPECTUS SUMMARY
This summary highlights information contained elsewhere or incorporated by reference into this prospectus. This summary does not contain all of the
information that you should consider before deciding to invest in our securities. You should read this entire prospectus and the accompanying prospectus carefully, including the "Risk Factors" section contained in this prospectus and our
consolidated financial statements and the related notes and the other documents incorporated by reference into this prospectus and in the accompanying prospectus. Unless we have indicated otherwise or the context otherwise requires, references in
this prospectus or the documents incorporated by reference herein and therein to the "Company," "we," "us" and "our" refer to Sorrento Therapeutics, Inc. and its subsidiaries.
Business Overview
We are a
biopharmaceutical company engaged in the discovery, acquisition, development and commercialization of proprietary drug therapeutics for addressing significant unmet medical needs in the U.S., Europe and additional international markets. Our primary
therapeutic focus is oncology, including the treatment of chronic cancer pain, but we are also developing therapeutic products for other indications, including immunology and infectious diseases. We currently have two clinical development programs
underway: (i) our lead oncology drug product candidate Cynviloq™, a micellar diblock copolymeric paclitaxel formulation, and (ii) resiniferatoxin, a non-opiate, ultra potent and selective agonist of the TRPV-1 receptor for intractable
pain in end-stage disease.
Our pipeline also includes preclinical fully human therapeutic antibodies, including our fully human
anti-PD-L1 and anti-PD-1 monoclonal antibodies, or Abs, derived from our proprietary G-MAB
®
library platform, antibody drug conjugates, or ADCs, and recombinant intravenous immunoglobulin, or
rIVIG. Our objective is to develop two classes of antibody drug products, therapeutic antibodies and ADCs: (i) First in Class, or FIC, and/or (ii) Best in Class, or BIC, which may offer greater efficacy and/or fewer adverse events or side
effects as compared to existing drugs.
Although we intend to retain ownership and control of some product candidates by advancing their
development, we will also consider partnerships with pharmaceutical or biopharmaceutical companies in order to balance the risks associated with drug discovery and development and maximize our stockholders' returns. Our partnering objectives
include generating revenue through license fees, milestone-related development fees and royalties by licensing rights to our product candidates.
Our goal is to deliver innovative, highly effective and safe treatment options to patients throughout the world. By working closely with
scientists, doctors, patient organizations and other health care specialists, we are committed to improving the lives of patients and assisting their caregivers in their fight against serious diseases.
Recent Developments
On March 31,
2014, we announced that the first patient has been dosed in the pivotal clinical trial designed to support Cynviloq for the treatment of metastatic breast cancer and non-small cell lung cancer. The registration trial is an open-label, randomized,
multi-center, single-dose, crossover registration study being conducted at clinical sites across the U.S., EU, and Singapore. A projected 100 patients with metastatic or locally recurrent breast cancer will be administered 260 mg/m
2
of Cynviloq or 260 mg/m
2
of Abraxane
®
using a 30 minute infusion in a crossover design to
compare the bioequivalence of both drugs. Based on the End-of-Phase II meeting with the U.S. Food and Drug Administration, or FDA, in July 2013, this trial was designed to gain marketing approval for Cynviloq under the 505(b)(2) regulatory pathway
in the U.S. We expect to file a New Drug Application with the FDA in the first half of 2015.
On March 31, 2014, we entered into an
amended and restated loan and security agreement with Oxford Finance LLC and Silicon Valley Bank, increasing the September 2013 facility from $5,000,000 to $12,500,000, with two banks. The amended and restated loan bears interest at 7.95% per
annum. We will make interest only payments on the outstanding amount of the loan on a monthly basis until October 1, 2014, after which equal monthly payments of principal and interest are due until the loan maturity date of September 30,
2017. In the event we raise $30 million of net equity or proceeds from a collaboration, if any, the interest only period will be extended by six months. Such loan is secured by a security interest in substantially all of our assets, excluding
intellectual property, which is subject to a negative pledge. In connection with the amended and restated loan and security agreement, the Lenders received a warrant to purchase an aggregate 34,642 shares of our common stock at an exercise price of
$12.99 per share, which is exercisable for seven years from the date of issuance.

RISK FACTORS
You should carefully consider the risks described below before making an investment decision. The risks described below are not the only ones we face.
Additional risks we are not presently aware of or that we currently believe are immaterial may also impair our business operations. Our business could be harmed by any of these risks. The trading price of our common stock could decline due to any of
these risks, and you may lose all or part of your investment. In assessing these risks, you should also refer to the other information contained or incorporated by reference into this prospectus, including our financial statements and related notes.
Risks Related to Our Financial Position and Capital Requirements
We are a development-stage company subject to all of the risks and uncertainties of a new business, including the risk that we or our partners may never
develop, complete development or market any of our product candidates or generate product related revenues.
We are a
development-stage biopharmaceutical company that began operating and commenced research and development activities in 2009. Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. There is
no assurance that our libraries of fully-human mAbs will be suitable for diagnostic or therapeutic use, or that we will be able to identify and isolate therapeutics product candidates, or develop, market and commercialize these candidates. We do not
expect any of our fully-human mAb, ADC, RTX, Cynviloq or related companion diagnostic product candidates to be commercially available for a few years, if at all. Even if we are able to commercialize our product candidates, there is no assurance that
these candidates would generate revenues or that any revenues generated would be sufficient for us to become profitable or thereafter maintain profitability.
We do not have any products that are approved for commercial sale and therefore do not expect to generate any revenues from product sales in the
foreseeable future, if ever.
We have not generated any product related revenues to date, and do not expect to generate any such
revenues for at least the next several years, if at all. To obtain revenues from sales of our product candidates, we must succeed, either alone or with third parties, in developing, obtaining regulatory approval for, manufacturing and marketing
products with commercial potential. We may never succeed in these activities, and we may not generate sufficient revenues to continue our business operations or achieve profitability.
We have incurred significant losses since inception and anticipate that we will incur continued losses for the foreseeable future.
As of December 31, 2013 and 2012, we had an accumulated deficit of $32.9 million and $11.0 million, respectively. We have incurred
operating losses since our inception, expect to continue to incur significant operating losses for the foreseeable future, and we expect these losses to increase as we: (i) conduct our BE registration trial related to Cynviloq and prepare for
our New Drug Application filing anticipated in 2015, (ii) advance RTX into clinical trials and potentially pursue other human or veterinary indications, (iii) continue to identify and advance a number of potential mAb and ADC drug
candidates into preclinical and clinical development activities, (iv) continue our development of, and seek regulatory approvals for, our product candidates, and begin to commercialize any approved products, and (v) expand our corporate
infrastructure, including the costs associated with being a NASDAQ public company. As such, we are subject to all risks incidental to the development of new biopharmaceutical products and related companion diagnostics, and we may encounter
unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on our
stockholders' equity and working capital.
We will require substantial additional funding which may not be available to us on acceptable terms,
or at all. If we fail to raise the necessary additional capital, we may be unable to complete the development and commercialization of our product candidates, or continue our development programs.
Our operations have consumed substantial amounts of cash since inception. We expect to significantly increase our spending to advance the
preclinical and clinical development of our product candidates and launch and commercialize any product candidates for which we receive regulatory approval, including building our own commercial organizations to address certain markets. We will
require additional capital for the further development and commercialization of our product candidates, as well as to fund our other operating expenses and capital expenditures.

Table of Contents
We cannot be certain that additional funding will be available on acceptable terms, or at all. If
we are unable to raise additional capital in sufficient amounts or on terms acceptable to us we may have to significantly delay, scale back or discontinue the development or commercialization of one or more of our product candidates. We may also
seek collaborators for one or more of our current or future product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available. Any of these events could significantly harm
our business, financial condition and prospects.
Our future capital requirements will depend on many factors, including:
•
the progress of the development of our fully-human mAb, ADC, RTX, Cynviloq or related companion diagnostic product candidates;
•
the number of product candidates we pursue;
•
the time and costs involved in obtaining regulatory approvals;
•
the costs involved in filing and prosecuting patent applications and enforcing or defending patent claims;
•
our plans to establish sales, marketing and/or manufacturing capabilities;
•
the effect of competing technological and market developments;
•
the terms and timing of any collaborative, licensing and other arrangements that we may establish;
•
general market conditions for offerings from biopharmaceutical companies;
•
our ability to establish, enforce and maintain selected strategic alliances and activities required for product commercialization; and
•
our revenues, if any, from successful development and commercialization of our product candidates.
In order to carry out our business plan and implement our strategy, we anticipate that we will need to obtain additional financing from time
to time and may choose to raise additional funds through strategic collaborations, licensing arrangements, public or private equity or debt financing, bank lines of credit, asset sales, government grants, or other arrangements. We cannot be sure
that any additional funding, if needed, will be available on terms favorable to us or at all. Furthermore, any additional equity or equity-related financing may be dilutive to our stockholders, and debt or equity financing, if available, may subject
us to restrictive covenants and significant interest costs. If we obtain funding through a strategic collaboration or licensing arrangement, we may be required to relinquish our rights to certain of our product candidates or marketing territories.
Further, there is uncertainty related to future NIH grant funding, and the NIH plans for new grants or cooperative agreements may be
re-scoped, delayed, or canceled depending on the nature of the work and the availability of resources. As a result, we cannot assure you that we will receive any additional funding under our existing NIH grants, and we may not be successful in
securing additional grants from the NIH in the future.
Our inability to raise capital when needed would harm our business, financial
condition and results of operations, and could cause our stock price to decline or require that we wind down our operations altogether.
Risks Related
to Our Business and Industry
We are heavily dependent on the success of our technologies and product candidates, and we cannot give any
assurance that any of our product candidates will receive regulatory approval, which is necessary before they can be commercialized.
To date, we have invested a significant portion of our efforts and financial resources in the acquisition and development of our product
candidates. We have not demonstrated our ability to perform the functions necessary for the successful acquisition, development or commercialization of the technologies we are seeking to develop. As an early stage company, we have limited experience
and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical area. Our future success is
substantially dependent on our ability to successfully develop, obtain regulatory approval for, and then successfully commercialize such product candidates. Our product candidates are currently in preclinical development or in clinical trials. Our
business depends entirely on the successful development and commercialization of our product candidates, which may never occur. We currently generate no revenues from sales of any drugs, and we may never be able to develop or commercialize a
marketable drug.
The successful development, and any commercialization, of our technologies and any product candidates would require us
to successfully perform a variety of functions, including:
•
developing our technology platform;
•
identifying, developing, manufacturing and commercializing product candidates;
7
Table of Contents
•
entering into successful licensing and other arrangements with product development partners;
•
participating in regulatory approval processes;
•
formulating and manufacturing products; and
•
conducting sales and marketing activities.
Our operations have been limited to organizing our
company, acquiring, developing and securing our proprietary technology and identifying and obtaining early preclinical data or clinical data for various product candidates. These operations provide a limited basis for you to assess our ability to
continue to develop our technology, identify product candidates, develop and commercialize any product candidates we are able to identify and enter into successful collaborative arrangements with other companies, as well as for you to assess the
advisability of investing in our securities. Each of these requirements will require substantial time, effort and financial resources.
Each of our product candidates will require additional preclinical or clinical development, management of preclinical, clinical and
manufacturing activities, regulatory approval in multiple jurisdictions, obtaining manufacturing supply, building of a commercial organization, and significant marketing efforts before we generate any revenues from product sales. We are not
permitted to market or promote any of our product candidates before we receive regulatory approval from the U.S. Food and Drug Administration, or FDA, or comparable foreign regulatory authorities, and we may never receive such regulatory approval
for any of our product candidates. In addition, our product development programs contemplate the development of companion diagnostics by our third-party collaborators. Companion diagnostics are subject to regulation as medical devices and must
themselves be approved for marketing by the FDA or certain other foreign regulatory agencies before we may commercialize our product candidates.
Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be
predictive of future trial results.
Clinical testing is expensive and can take many years to complete, and its outcome is
inherently uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials.
Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. It is not uncommon for companies in the
biopharmaceutical industry to suffer significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. Our future clinical trial results may not be successful.
This drug candidate development risk is heightened by any changes in the planned clinical trials compared to the completed clinical
trials. As product candidates are developed through preclinical to early and late stage clinical trials towards approval and commercialization, it is customary that various aspects of the development program, such as manufacturing and methods of
administration, are altered along the way in an effort to optimize processes and results. While these types of changes are common and are intended to optimize the product candidates for late stage clinical trials, approval and commercialization,
such changes do carry the risk that they will not achieve these intended objectives.
We have not previously initiated or completed a
corporate-sponsored clinical trial. Consequently, we may not have the necessary capabilities, including adequate staffing, to successfully manage the execution and completion of any clinical trials we initiate, including our planned clinical trials
of Cynviloq and RTX, in a way that leads to our obtaining marketing approval for our product candidates in a timely manner, or at all.
In
the event we are able to conduct a pivotal clinical trial of a product candidate, the results of such trial may not be adequate to support marketing approval. Because our product candidates are intended for use in life-threatening diseases, in some
cases we ultimately intend to seek marketing approval for each product candidate based on the results of a single pivotal clinical trial. As a result, these trials may receive enhanced scrutiny from the FDA. For any such pivotal trial, if the FDA
disagrees with our choice of primary endpoint or the results for the primary endpoint are not robust or significant relative to control, are subject to confounding factors, or are not adequately supported by other study endpoints, including possibly
overall survival or complete response rate, the FDA may refuse to approve a BLA based on such pivotal trial. The FDA may require additional clinical trials as a condition for approving our product candidates.
In some of our future trials, we may combine Cynviloq with other therapies such as chemotherapy or immunotherapy. We have not yet tested these
combinations.

Table of Contents
Delays in clinical testing could result in increased costs to us and delay our ability to generate revenue.
Although we are planning for certain clinical trials relating to Cynviloq and RTX, there can be no assurance that the FDA will
accept our proposed trial designs. We may experience delays in our clinical trials and we do not know whether planned clinical trials will begin on time, need to be redesigned, enroll patients on time or be completed on schedule, if at all. Clinical
trials can be delayed for a variety of reasons, including delays related to:
•
obtaining regulatory approval to commence a trial;
•
reaching agreement on acceptable terms with prospective contract research organizations, or CROs, and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among
different CROs and trial sites;
•
obtaining institutional review board, or IRB, approval at each site;
•
recruiting suitable patients to participate in a trial;
•
clinical sites deviating from trial protocol or dropping out of a trial;
•
having patients complete a trial or return for post-treatment follow-up;
•
developing and validating companion diagnostics on a timely basis, if required;
•
adding new clinical trial sites; or
•
manufacturing sufficient quantities of product candidate for use in clinical trials.
Patient
enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the design
of the clinical trial, competing clinical trials and clinicians' and patients' perceptions as to the potential advantages of the drug being studied in relation to other available therapies, including any new drugs that may be approved for
the indications we are investigating. Furthermore, we intend to rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and we intend to have agreements governing their committed activities, we will have
limited influence over their actual performance.
We could encounter delays if a clinical trial is suspended or terminated by us, by the
IRBs of the institutions in which such trials are being conducted, by the Data Safety Monitoring Board, or DSMB, for such trial or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination due to a
number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting
in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the
clinical trial.
If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the
commercial prospects of our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow
down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition,
many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates.
Competition for patients in conducting clinical trials may prevent or delay product development and strain our limited financial resources.
Many pharmaceutical companies are conducting clinical trials in patients with the disease indications that our potential drug products target.
As a result, we must compete with them for clinical sites, physicians and the limited number of patients who fulfill the stringent requirements for participation in clinical trials. Also, due to the confidential nature of clinical trials, we do not
know how many of the eligible patients may be enrolled in competing studies and who are consequently not available to us for our clinical trials. Our clinical trials may be delayed or terminated due to the inability to enroll enough patients.
Patient enrollment depends on many factors, including the size of the patient population, the nature of the trial protocol, the proximity of patients to clinical sites and the eligibility criteria for the study. The delay or inability to meet
planned patient enrollment may result in increased costs and delays or termination of the trial, which could have a harmful effect on our ability to develop products.

The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming
and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially harmed.
The time required to obtain approval by the FDA and comparable foreign authorities is unpredictable but typically takes many years following
the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain
approval may change during the course of a product candidate's clinical development and may vary among jurisdictions. We have not obtained regulatory approval for any product candidate and it is possible that none of our existing product
candidates or any product candidates we may seek to develop in the future will ever obtain regulatory approval.
Our product candidates
could fail to receive regulatory approval for many reasons, including the following:
•
the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials;
•
we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that a product candidate is safe and effective for its proposed indication;
•
the results of clinical trials may not meet the level of statistical significance required by the FDA or comparable foreign regulatory authorities for approval;
•
the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials;
•
the data collected from clinical trials of our product candidates may not be sufficient to support the submission of an NDA or other submission or to obtain regulatory approval in the United States or elsewhere;
•
the FDA or comparable foreign regulatory authorities may fail to approve the manufacturing processes or facilities of third-party manufacturers with which we contract for clinical and commercial supplies;
•
the FDA or comparable foreign regulatory authorities may fail to approve the companion diagnostics we contemplate developing with partners; and
•
the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval.
This lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory
approval to market our product candidates, which would significantly harm our business, results of operations and prospects.
In addition,
even if we were to obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited indications than we request, may not approve the price we intend to charge for our products, may grant approval contingent
on the performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Any of the
foregoing scenarios could materially harm the commercial prospects for our product candidates.
We have not previously submitted a
biologics license application, or BLA, or a New Drug Application, or NDA, to the FDA, or similar drug approval filings to comparable foreign authorities, for any product candidate, and we cannot be certain that any of our product candidates will be
successful in clinical trials or receive regulatory approval. Further, our product candidates may not receive regulatory approval even if they are successful in clinical trials. If we do not receive regulatory approvals for our product candidates,
we may not be able to continue our operations. Even if we successfully obtain regulatory approvals to market one or more of our product candidates, our revenues will be dependent, in part, upon our collaborators' ability to obtain regulatory
approval of the companion diagnostics to be used with our product candidates, as well as the size of the markets in the territories for which we gain regulatory approval and have commercial rights. If the markets for patients that we are targeting
for our product candidates are not as significant as we estimate, we may not generate significant revenues from sales of such products, if approved.
We plan to seek regulatory approval to commercialize our product candidates both in the U.S., the European Union and in additional foreign
countries. While the scope of regulatory approval is similar in other countries, to obtain separate regulatory approval in many other countries we must comply with numerous and varying regulatory requirements of such countries regarding safety and
efficacy and governing, among other things, clinical trials and commercial sales, pricing and distribution of our product candidates, and we cannot predict success in these jurisdictions.
Our most rapid and cost effective access to market approval for Cynviloq depends on meeting the conditions for approval under Section 505(b)(2) of
the Federal Food, Drug and Cosmetic Act, or FFDCA.
We are seeking approval for Cynviloq under Section 505(b)(2) of the
FFDCA, enacted as part of the Drug Price Competition and Patent Restoration Act of 1984, otherwise known as the Hatch-Waxman Act, which permits applicants to rely in part on preclinical and clinical data generated by third parties.
10
Table of Contents
Specifically, with respect to Cynviloq, we are relying in part on third party data on
paclitaxel, which is the active ingredient in Cynviloq and the previously approved products Abraxane and Taxol. There can be no assurance that the FDA will not require us to conduct additional preclinical or clinical studies or otherwise
obtain new supplementary data with respect to some or all of the data upon which we may rely prior to approving a Cynviloq NDA.
Our NDA
also relies on prior FDA findings of safety and effectiveness of previously approved products, and we will make certifications in our NDA under Section 505(b)(2) requirements based on the listed patents in the FDA publication "Approved
Drug Products with Therapeutics Equivalence Evaluations," or the Orange Book, for certain of these referenced products. In the event that one or more patents is listed in the Orange Book for the referenced product after our submission of
additional information in support of our NDA for Cynviloq, we may also be required to evaluate the applicability of these patents to Cynviloq and submit additional certifications. A paragraph III certification, stating that a listed patent
has not expired, but will expire on a particular date, may delay the approval of Cynviloq until the expiration of the patent. A paragraph IV certification, stating that a listed patent is invalid, unenforceable, or not infringed
by Cynviloq may require us to notify the patent owner and the holder of the NDA for the referenced product of the existence of the Cynviloq NDA, and may result in patent litigation against us and the entry of a 30-month stay of FDA
ability to issue final approval of the 505(b)(2) NDA for Cynviloq.
Our success also relies, in part, on obtaining Hatch-Waxman
marketing exclusivity in connection with any approval of our NDA for Cynviloq. Such exclusivity protection would preclude the FDA from approving a marketing application for a duplicate of Cynviloq, a product candidate that the FDA views as
having the same conditions of approval as Cynviloq (for example, the same indication, the same route of delivery and/or other conditions of use), or a 505(b)(2) NDA submitted to the FDA with Cynviloq as the reference product, for
a period of three years from the date of Cynviloq approval, although the FDA may accept and commence review of such applications. This form of exclusivity may not prevent FDA approval of an NDA that relies only on its own data to support
the change or innovation. Similarly, if, prior to approval of the Cynviloq NDA, another company obtains approval for a product candidate under, in the view of the FDA, the same conditions of approval that we are seeking
for Cynviloq, Cynviloq could be blocked until the other company's three-year Hatch-Waxman marketing exclusivity expires.
Our
approach to the discovery and development of product candidates that target ADCs and rIVIG is unproven, and we do not know whether we will be able to develop any products of commercial value.
ADCs and rIVIG are emerging technologies and, consequently, it is conceivable that such technologies may ultimately fail to identify
commercially viable drugs to treat human patients with cancer or other diseases.
Our product candidates may cause undesirable side effects or have
other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.
Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials
and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities. To date, patients treated with Cynviloq have experienced drug-related side effects such as neutropenia,
leukopenia, anemia, thrombocytopenia, peripheral neuropathy, myalgia nausea, vomiting, diarrhea, alopecia, rash, pruritus and hypersensitivity reactions. The clinical evaluation of Cynviloq is still in the early stages, but as is the case with all
oncology drugs, it is likely that there may be side effects associated with its use. Results of our trials could reveal a high and unacceptable severity and prevalence of these or other side effects. In such an event, our trials could be suspended
or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. The drug-related side effects could affect patient
recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.
Additionally if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects
caused by such products, a number of potentially significant negative consequences could result, including:
•
regulatory authorities may withdraw approvals of such product;
•
regulatory authorities may require additional warnings on the label;
•
we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;
•
we could be sued and held liable for harm caused to patients; and
•
our reputation may suffer.
11
Table of Contents
Any of these events could prevent us from achieving or maintaining market acceptance of the
particular product candidate or for particular indications of a product candidate, if approved, and could significantly harm our business, results of operations and prospects.
We rely on third parties to conduct our preclinical and clinical trials. If these third parties do not successfully perform their contractual legal and
regulatory duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed.
We have relied upon and plan to continue to rely upon third-party CROs to monitor and manage data for our ongoing preclinical and clinical
programs. We rely on these parties for execution of our preclinical and clinical trials, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the
applicable protocol, legal, regulatory and scientific standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities. We and our CROs are required to comply with current good clinical practices, or cGCP, which are
regulations and guidelines enforced by the FDA, the Competent Authorities of the Member States of the European Economic Area, or EEA, and comparable foreign regulatory authorities for all of our products in clinical development. Regulatory
authorities enforce these cGCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs fail to comply with applicable cGCPs, the clinical data generated in our clinical trials may be deemed
unreliable and the FDA, the European Medicines Agency, or EMA, or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection
by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with cGCP regulations. In addition, our clinical trials must be conducted with product produced under current good manufacturing
practices, or cGMP, regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process.
If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to
do so on commercially reasonable terms. In addition, our CROs are not our employees, and except for remedies available to us under our agreements with such CROs, we cannot control whether or not they devote sufficient time and resources to our
on-going
clinical, nonclinical and preclinical programs. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or
accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to
obtain regulatory approval for or successfully commercialize our product candidates. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate
revenues could be delayed.
Switching or adding additional CROs involves additional cost and requires management time and focus. In
addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Though we carefully manage our relationships with
our CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.
We expect to rely on third parties to manufacture our clinical drug supplies and we intend to rely on third parties to produce commercial supplies of
any approved product candidate, and our commercialization of any of our product candidates could be stopped, delayed or made less profitable if those third parties fail to obtain approval of the FDA or comparable foreign regulatory authorities, fail
to provide us with sufficient quantities of drug product or fail to do so at acceptable quality levels or prices.
We do not
currently have nor do we plan to acquire the infrastructure or capability internally to manufacture our clinical drug supplies for use in the conduct of our clinical trials, and we lack the resources and the capability to manufacture any of our
product candidates on a clinical or commercial scale. We do not control the manufacturing process of, and are completely dependent on, our contract manufacturing partners for compliance with the cGMP regulatory requirements for manufacture of both
active drug substances and finished drug products. If our contract manufacturers cannot successfully manufacture material that conforms to the strict regulatory requirements of the FDA or others, they will not be able to secure and/or maintain
regulatory approval for their manufacturing facilities. In addition, we have no control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable
foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly
impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved.

Table of Contents
Material necessary to manufacture our product candidates may not be available on commercially reasonable
terms, or at all, which may delay the development and commercialization of our product candidates.
We rely on our manufacturers to
produce or purchase from third-party suppliers the materials necessary to produce our product candidates for our clinical trials. There are a limited number of suppliers for raw materials that we use to manufacture our drugs and there may be a need
to assess alternate suppliers to prevent a possible disruption of the manufacture of the materials necessary to produce our product candidates for our clinical trials, and if approved, ultimately for commercial sale. We do not have any control over
the process or timing of the acquisition of these raw materials by our manufacturers. Except for the manufacture and supply of Cynviloq, we currently do not have any agreements for the commercial production of these raw materials. Any significant
delay in the supply of a product candidate, or the raw material components thereof, for an ongoing clinical trial due to the need to replace a third-party manufacturer could considerably delay completion of our clinical trials, product testing and
potential regulatory approval of our product candidates. If our manufacturers or we are unable to purchase these raw materials after regulatory approval has been obtained for our product candidates, the commercial launch of our product candidates
would be delayed or there would be a shortage in supply, which would impair our ability to generate revenues from the sale of our product candidates.
We expect to continue to depend on third-party contract manufacturers for the foreseeable future. We have not entered into long-term
agreements with all of our current contract manufacturers or with any alternate fill/finish suppliers, and though we intend to do so prior to commercial launch in order to ensure that we maintain adequate supplies of finished drug product, we may be
unable to enter into such an agreement or do so on commercially reasonable terms, which could have a material adverse impact upon our business. We currently obtain our supplies of finished drug product through individual purchase orders.
We may not be able to manufacture our product candidates in commercial quantities, which would prevent us from commercializing our product candidates.
We are dependent on our third party manufacturers to conduct process development and scale-up work necessary to support greater
clinical development and commercialization requirements for our product candidates. Carrying out these activities in a timely manner, and on commercially reasonable terms, is critical to the successful development and commercialization of our
product candidates. We expect our third-party manufacturers are capable of providing sufficient quantities of our product candidates to meet anticipated clinical and full-scale commercial demands, however if third parties with whom we currently work
are unable to meet our supply requirements, we will need to secure alternate suppliers. While we believe that there are other contract manufacturers having the technical capabilities to manufacture our product candidates, we cannot be certain that
identifying and establishing relationships with such sources would not result in significant delay or material additional costs.
We currently have
no sales and marketing organization. If we are unable to establish a direct sales force in the U.S. to promote our products, the commercial opportunity for our products may be diminished.
We currently have no sales and marketing organization. If any of our product candidates are approved by the FDA, we intend to market that
product through our own sales force. We will incur significant additional expenses and commit significant additional management resources to establish our sales force. We may not be able to establish these capabilities despite these additional
expenditures. We will also have to compete with other pharmaceutical and biotechnology companies to recruit, hire and train sales and marketing personnel. If we elect to rely on third parties to sell our product candidates in the U.S., we may
receive less revenue than if we sold our products directly. In addition, although we would intend to use due diligence in monitoring their activities, we may have little or no control over the sales efforts of those third parties. In the event we
are unable to develop our own sales force or collaborate with a third party to sell our product candidates, we may not be able to commercialize our product candidates which would negatively impact our ability to generate revenue.
We may need others to market and commercialize our product candidates in international markets.
In the future, if appropriate regulatory approvals are obtained, we may commercialize our product candidates in international markets. However,
we have not decided how to commercialize our product candidates in those markets. We may decide to build our own sales force or sell our products through third parties. If we decide to sell our product candidates in international markets through a
third party, we may not be able to enter into any marketing arrangements on favorable terms or at all. In addition, these arrangements could result in lower levels of income to us than if we marketed our product candidates entirely on our own. If we
are unable to enter into a marketing arrangement for our product candidates in international markets, we may not be able to develop an effective international sales force to successfully commercialize those products in international markets. If we
fail to enter into marketing arrangements for our products and are unable to develop an effective international sales force, our ability to generate revenue would be limited.

Even if we receive regulatory approval for any of our product candidates, we will be subject to ongoing
obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to
penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products.
Any regulatory
approvals that we receive for our product candidates may also be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly
post-marketing testing, including Phase IV clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. In addition, if the FDA or a comparable foreign regulatory authority approves any of our product
candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These
requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMPs and cGCPs for any clinical trials that we conduct post-approval. The future discovery of previously
unknown problems with a product, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:
•
restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, or voluntary or mandatory product recalls;
•
fines, warning letters or holds on clinical trials;
•
refusal by the FDA to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of product license approvals;
•
product seizure or detention, or refusal to permit the import or export of products; and
•
injunctions or the imposition of civil or criminal penalties.
The FDA's policies may
change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements
or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.
We will need to obtain FDA approval of any proposed product brand names, and any failure or delay associated with such approval may adversely impact our
business.
A pharmaceutical product cannot be marketed in the U.S. or other countries until we have completed rigorous and
extensive regulatory review processes, including approval of a brand name. Any brand names we intend to use for our product candidates will require approval from the FDA regardless of whether we have secured a formal trademark registration from the
U.S. Patent and Trademark Office, or the PTO. The FDA typically conducts a review of proposed product brand names, including an evaluation of potential for confusion with other product names. The FDA may also object to a product brand name if we
believe the name inappropriately implies medical claims. If the FDA objects to any of our proposed product brand names, we may be required to adopt an alternative brand name for our product candidates. If we adopt an alternative brand name, we would
lose the benefit of our existing trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a suitable product brand name that would qualify under applicable trademark
laws, not infringe the existing rights of third parties and be acceptable to the FDA. We may be unable to build a successful brand identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our product
candidates.
Our failure to successfully discover, acquire, develop and market additional product candidates or approved products would impair our
ability to grow.
As part of our growth strategy, we intend to develop and market additional products and product candidates. We
are pursuing various therapeutic opportunities through our pipeline. We may spend several years completing our development of any particular current or future internal product candidate, and failure can occur at any stage. The product candidates to
which we allocate our resources may not end up being successful. In addition, because our internal research capabilities are limited, we may be dependent upon pharmaceutical and biotechnology companies, academic scientists and other researchers to
sell or license products or technology to us. The success of this strategy depends partly upon our ability to identify, select, discover and acquire promising pharmaceutical product candidates and products. Failure of this strategy would impair our
ability to grow.
The process of proposing, negotiating and implementing a license or acquisition of a product candidate or approved
product is lengthy and complex. Other companies, including some with substantially greater financial, marketing and sales resources, may compete with us for the license or acquisition of product candidates and approved products. We have limited
resources to identify and execute the acquisition or in-licensing of third-party products, businesses and technologies and integrate them into our current infrastructure. Moreover, we may devote resources to potential acquisitions or in-licensing
opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts. We may not be able to acquire the rights to additional product candidates on terms that we find acceptable, or at all.
14
Table of Contents
In addition, future acquisitions may entail numerous operational and financial risks, including:
•
disruption of our business and diversion of our management's time and attention to develop acquired products or technologies;
•
incurrence of substantial debt, dilutive issuances of securities or depletion of cash to pay for acquisitions;
•
higher than expected acquisition and integration costs;
•
difficulty in combining the operations and personnel of any acquired businesses with our operations and personnel;
•
increased amortization expenses;
•
impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership;
•
inability to motivate key employees of any acquired businesses; and
•
assumption of known and unknown liabilities.
Further, any product candidate that we acquire
may require additional development efforts prior to commercial sale, including extensive clinical testing and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to risks of failure typical of
pharmaceutical product development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities.
Our commercial success depends upon us attaining significant market acceptance of our product candidates, if approved for sale, among physicians,
patients, healthcare payors and major operators of cancer and other clinics.
Even if we obtain regulatory approval for our product
candidates, the product may not gain market acceptance among physicians, health care payors, patients and the medical community, which are critical to commercial success. Market acceptance of any product candidate for which we receive approval
depends on a number of factors, including:
•
the efficacy and safety as demonstrated in clinical trials;
•
the timing of market introduction of such product candidate as well as competitive products;
•
the clinical indications for which the drug is approved;
•
acceptance by physicians, major operators of cancer clinics and patients of the drug as a safe and effective treatment;
•
the safety of such product candidate seen in a broader patient group, including its use outside the approved indications;
•
the availability, cost and potential advantages of alternative treatments, including less expensive generic drugs;
•
the availability of adequate reimbursement and pricing by third-party payors and government authorities;
•
the relative convenience and ease of administration of Cynviloq for clinical practices;
•
the product labeling or product insert required by the FDA or regulatory authority in other countries;
•
the approval, availability, market acceptance and reimbursement for a companion diagnostic, if any;
•
the prevalence and severity of adverse side effects; and
•
the effectiveness of our sales and marketing efforts.
If any product candidate that we
develop does not provide a treatment regimen that is as beneficial as, or is perceived as being as beneficial as, the current standard of care or otherwise does not provide patient benefit, that product candidate, if approved for commercial sale by
the FDA or other regulatory authorities, likely will not achieve market acceptance. Our ability to effectively promote and sell any approved products will also depend on pricing and cost-effectiveness, including our ability to produce a product at a
competitive price and our ability to obtain sufficient third-party coverage or reimbursement. If any product candidate is approved but does not achieve an adequate level of acceptance by physicians, patients and third-party payors, our ability to
generate revenues from that product would be substantially reduced. In addition, our efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources, may be constrained by
FDA rules and policies on product promotion, and may never be successful.
If we fail to develop Cynviloq for additional indications, our
commercial opportunity will be limited.
To date, our initial focus has been on the development of Cynviloq for the treatment of
MBC and NSCLC. A key element of our strategy is to pursue clinical development of Cynviloq for bladder cancer and ovarian cancer, and potentially for other indications. Although we believe there is large commercial opportunity for the treatment of
MBC and NSCLC alone, our ability to generate and
15
Table of Contents
grow revenues will be highly dependent on our ability to successfully develop and commercialize Cynviloq for the treatment of additional indications. The development of Cynviloq for additional
indications is prone to the risks of failure inherent in drug development and we cannot provide you any assurance that we will be able to successfully advance any of these programs through the development process. Even if we receive FDA approval to
market Cynviloq for the treatment of any additional indications, we cannot assure you that any such indications will be successfully commercialized, widely accepted in the marketplace or more effective than other commercially available alternatives.
If we are unable to successfully develop and commercialize Cynviloq for additional indications, our commercial opportunity will be limited and our business prospects will suffer.
If we cannot compete successfully against other biotechnology and pharmaceutical companies, we may not be successful in developing and commercializing
our technology and our business will suffer.
The biotechnology and pharmaceutical industries are characterized by intense
competition and rapid technological advances, both in the U.S. and internationally. In addition, the competition in the oncology market is intense. For example, our late-stage product candidate, Cynviloq, may compete directly with a marketed
product, Abraxane, for certain cancer indications. Abraxane is already approved for MBC, NSCLC and pancreatic cancer, and approval is being pursued for and melanoma cancer. Even if we are able to develop our proprietary platform technology and
additional antibody libraries, each will compete with a number of existing and future technologies and product candidates developed, manufactured and marketed by others. Specifically, we will compete against fully integrated pharmaceutical companies
and smaller companies that are collaborating with larger pharmaceutical companies, academic institutions, government agencies and other public and private research organizations. Many of these competitors have validated technologies with products
already FDA-approved or in various stages of development. In addition, many of these competitors, either alone or together with their collaborative partners, operate larger research and development programs and have substantially greater financial
resources than we do, as well as significantly greater experience in:
•
developing product candidates and technologies generally;
•
undertaking preclinical testing and clinical trials;
•
obtaining FDA and other regulatory approvals of product candidates;
•
formulating and manufacturing product candidates; and
•
launching, marketing and selling product candidates.
Many of our competitors have
substantially greater financial, technical and other resources, such as larger research and development staff and experienced marketing and manufacturing organizations. Additional mergers and acquisitions in the biotechnology and pharmaceutical
industries may result in even more resources being concentrated in our competitors. As a result, these companies may obtain regulatory approval more rapidly than we are able and may be more effective in selling and marketing their products as well.
Smaller or early-stage companies or generic pharmaceutical manufacturers may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. Competition may increase further as a result of
advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Our competitors may succeed in developing, acquiring or licensing on an exclusive basis drug products that are more
effective or less costly than any drug candidate that we are currently developing or that we may develop. If approved, our product candidates will face competition from commercially available drugs as well as drugs that are in the development
pipelines of our competitors and later enter the market.
Established pharmaceutical companies may invest heavily to accelerate discovery
and development of novel compounds or to
in-license
novel compounds that could make our product candidates less competitive. In addition, any new product that competes with an approved product must demonstrate
compelling advantages in efficacy, convenience, tolerability and safety in order to overcome price competition and to be commercially successful. Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA, EMA or other
regulatory approval or discovering, developing and commercializing medicines before we do, which would have a material adverse impact on our business. If our technologies fail to compete effectively against third party technologies, our business
will be adversely impacted.
We expect that our ability to compete effectively will depend upon our ability to:
•
successfully and rapidly complete clinical trials and submit for and obtain all requisite regulatory approvals in a cost-effective manner;
•
maintain a proprietary position for our products and manufacturing processes and other related product technology;
•
attract and retain key personnel;
•
develop relationships with physicians prescribing these products; and
16
Table of Contents
•
build an adequate sales and marketing infrastructure for our product candidates.
Because we
will be competing against significantly larger companies with established track records, we will have to demonstrate that, based on experience, clinical data, side-effect profiles and other factors, our products, if approved, are competitive with
other products.
If approved, Cynviloq will face competition from less expensive generic products of competitors and, if we are unable to
differentiate the benefits of Cynviloq over these less expensive alternatives, we may never generate meaningful product revenues.
Generic paclitaxel therapies are typically sold at lower prices than branded paclitaxel therapies and are generally preferred by hospital
formularies and managed care providers of health services. We anticipate that, if approved, Cynviloq will face increasing competition in the form of generic versions of branded products of competitors that have lost or will lose their patent
exclusivity. For example, Cynviloq if approved, will initially face competition from the less expensive generic forms of paclitaxel that are currently available such as Taxol, and, in the future, would face additional competition from a generic form
of Abraxane when the patents covering it begin to expire in approximately 2022, or earlier if the patents are successfully challenged. If we are unable to demonstrate to physicians and payers that the key differentiating features of Cynviloq
translate to overall clinical benefit or lower cost of care, we may not be able to compete with generic alternatives.
Reimbursement may be limited
or unavailable in certain market segments for our product candidates, which could make it difficult for us to sell our products profitably.
There is significant uncertainty related to the third-party coverage and reimbursement of newly approved drugs. We intend to seek approval to
market our product candidates in the U.S., Europe and other selected foreign jurisdictions. Market acceptance and sales of our product candidates in both domestic and international markets will depend significantly on the availability of adequate
coverage and reimbursement from third-party payors for any of our product candidates and may be affected by existing and future health care reform measures. Government and other third-party payors are increasingly attempting to contain healthcare
costs by limiting both coverage and the level of reimbursement for new drugs and, as a result, they may not cover or provide adequate payment for our product candidates. These payors may conclude that our product candidates are less safe, less
effective or less cost-effective than existing or future introduced products, and third-party payors may not approve our product candidates for coverage and reimbursement or may cease providing coverage and reimbursement for these product
candidates.
Obtaining coverage and reimbursement approval for a product from a government or other third-party payor is a time consuming
and costly process that could require us to provide to the payor supporting scientific, clinical and cost-effectiveness data for the use of our products. We may not be able to provide data sufficient to gain acceptance with respect to coverage and
reimbursement. If reimbursement of our future products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability.
In some foreign countries, particularly in the European Union, the pricing of prescription pharmaceuticals is subject to governmental control.
In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product candidate. To obtain reimbursement or pricing approval in some countries, we may be required to
conduct additional clinical trials that compare the cost-effectiveness of our product candidates to other available therapies. If reimbursement of our product candidates is unavailable or limited in scope or amount in a particular country, or if
pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability of our products in such country.
Healthcare reform
measures could hinder or prevent our product candidates' commercial success.
In both the U.S. and certain foreign
jurisdictions, there have been and we expect there will continue to be a number of legislative and regulatory changes to the health care system that could impact our ability to sell our products profitably. The U.S. government and other governments
have shown significant interest in pursuing healthcare reform. In particular, the Medicare Modernization Act of 2003 revised the payment methodology for many products under the Medicare program in the U.S. This has resulted in lower rates of
reimbursement. In 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, collectively, the Healthcare Reform Law, was enacted. The Healthcare Reform Law substantially changes the way
healthcare is financed by both governmental and private insurers. Such government-adopted reform measures may adversely impact the pricing of healthcare products and services in the U.S. or internationally and the amount of reimbursement available
from governmental agencies or other third-party payors.
There have been, and likely will continue to be, legislative and regulatory
proposals at the federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. We cannot predict the initiatives that may be adopted in the future. The continuing efforts of the
government, insurance companies, managed care organizations and other payors
17
Table of Contents
of healthcare services to contain or reduce costs of healthcare may adversely affect the demand for any drug products for which we may obtain regulatory approval, as well as our ability to set
satisfactory prices for our products, to generate revenues, and to achieve and maintain profitability.
Certain of our potential product candidates
are in early stages of development and any product candidates that we develop will require extensive preclinical and clinical testing before they are approved by the appropriate regulatory agency, if at all.
The FDA regulates, among other things, the development, testing, manufacture, safety, efficacy, record-keeping, labeling, storage, approval,
advertising, promotion, sale and distribution of biopharmaceutical products. We are in the early stages of developing potential product candidates, and any candidates that we develop will require extensive preclinical and clinical testing before
they will be approved by the FDA or another regulatory authority in a jurisdiction outside the U.S., if at all. We have not yet developed any product candidate; if we were to do so there are a number of requirements that we would be required to
satisfy in order to begin conducting preclinical trials and there can be no assurance that we will develop product candidates or complete the steps necessary to allow us to commence these trials. We cannot predict with any certainty the results of
preclinical testing or whether such trials would yield sufficient data to permit us, or those with whom we collaborate, to proceed with clinical development and ultimately submit an application for regulatory approval of our product candidates in
the U.S. or abroad, or whether such applications would be approved by the appropriate regulatory agency. Further, our product candidates may not receive regulatory approval even if they are successful in clinical trials. If we do not receive
regulatory approvals for our product candidates, we may not be able to continue our operations.
Failure to successfully validate, develop and
obtain regulatory approval for companion diagnostics could harm our long-term drug development strategy.
As one of the key
elements of our clinical development strategy, we seek to identify patients within a disease category or indication who may derive selective and meaningful benefit from the product candidates we are developing. In collaboration with partners, we
plan to develop companion diagnostics to help us to more accurately identify patients within a particular category or indication, both during our clinical trials and in connection with the commercialization of certain of our product candidates.
Companion diagnostics are subject to regulation by the FDA and comparable foreign regulatory authorities as medical devices and require separate regulatory approval prior to commercialization. We do not develop companion diagnostics internally and
thus we are dependent on the sustained cooperation and effort of our third-party collaborators in developing and obtaining approval for these companion diagnostics. We and our collaborators may encounter difficulties in developing and obtaining
approval for the companion diagnostics, including issues relating to selectivity/specificity, analytical validation, reproducibility, or clinical validation. Any delay or failure by our collaborators to develop or obtain regulatory approval of the
companion diagnostics could delay or prevent approval of our product candidates. In addition, our collaborators may encounter production difficulties that could constrain the supply of the companion diagnostics, and both they and we may have
difficulties gaining acceptance of the use of the companion diagnostics in the clinical community. If such companion diagnostics fail to gain market acceptance, it would have an adverse effect on our ability to derive revenues from sales of our
products. In addition, the diagnostic company with whom we contract may decide to discontinue selling or manufacturing the companion diagnostic that we anticipate using in connection with development and commercialization of our product candidates
or our relationship with such diagnostic company may otherwise terminate. We may not be able to enter into arrangements with another diagnostic company to obtain supplies of an alternative diagnostic test for use in connection with the development
and commercialization of our product candidates or do so on commercially reasonable terms, which could adversely affect and/or delay the development or commercialization of our product candidates.
Our product development efforts may not be successful.
Our product development efforts for our FIC therapeutic antibodies, ADC and rIVIG technologies are designed to focus on novel therapeutic
approaches and technologies that have not been widely studied. We are applying these approaches and technologies in our attempt to discover new treatments for conditions that are also the subject of research and development efforts of many other
companies. These approaches and technologies may never be successful.
Our failure to find third party collaborators to assist or share in the costs
of product development could materially harm our business, financial condition and results of operations.
Our strategy for the
development and commercialization of our proprietary product candidates may include the formation of collaborative arrangements with third parties. Potential third parties include biopharmaceutical, pharmaceutical and biotechnology companies,
academic institutions and other entities. Third-party collaborators may assist us in:
•
funding research, preclinical development, clinical trials and manufacturing;
•
seeking and obtaining regulatory approvals; and
18
Table of Contents
•
successfully commercializing any future product candidates.
If we are not able to establish
further collaboration agreements, we may be required to undertake product development and commercialization at our own expense. Such an undertaking may limit the number of product candidates that we will be able to develop, significantly increase
our capital requirements and place additional strain on our internal resources. Our failure to enter into additional collaborations could materially harm our business, financial condition and results of operations.
In addition, our dependence on licensing, collaboration and other agreements with third parties may subject us to a number of risks. These
agreements may not be on terms that prove favorable to us and may require us to relinquish certain rights in our product candidates. To the extent we agree to work exclusively with one collaborator in a given area, our opportunities to collaborate
with other entities could be curtailed. Lengthy negotiations with potential new collaborators may lead to delays in the research, development or commercialization of product candidates. The decision by our collaborators to pursue alternative
technologies or the failure of our collaborators to develop or commercialize successfully any product candidate to which they have obtained rights from us could materially harm our business, financial condition and results of operations.
Adverse economic conditions may have material adverse consequences on our business, results of operations and financial condition.
Unpredictable and unstable changes in economic conditions, including recession, inflation, increased government intervention, or other changes,
may adversely affect our general business strategy. We rely upon our ability to generate additional sources of liquidity and we may need to raise additional funds through public or private debt or equity financings in order to fund existing
operations or to take advantage of opportunities, including acquisitions of complementary businesses or technologies. Any adverse event would have a material adverse impact on our business, results of operations and financial condition.
Because our development activities are expected to rely heavily on sensitive and personal information, an area which is highly regulated by privacy
laws, we may not be able to generate, maintain or access essential patient samples or data to continue our research and development efforts in the future on reasonable terms and conditions, which may adversely affect our business.
We may have access to very sensitive data regarding patients whose tissue samples are used in our studies. This data will contain information
that is personal in nature. The maintenance of this data is subject to certain privacy-related laws, which impose upon us administrative and financial burdens, and litigation risks. For instance, the rules promulgated by the Department of Health and
Human Services under the Health Insurance Portability and Accountability Act, or HIPAA, create national standards to protect patients' medical records and other personal information in the U.S. These rules require that healthcare providers and
other covered entities obtain written authorizations from patients prior to disclosing protected health care information of the patient to companies. If the patient fails to execute an authorization or the authorization fails to contain all required
provisions, then we will not be allowed access to the patient's information and our research efforts can be substantially delayed. Furthermore, use of protected health information that is provided to us pursuant to a valid patient authorization
is subject to the limits set forth in the authorization (i.e., for use in research and in submissions to regulatory authorities for product approvals). As such, we are required to implement policies, procedures and reasonable and appropriate
security measures to protect individually identifiable health information we receive from covered entities, and to ensure such information is used only as authorized by the patient. Any violations of these rules by us could subject us to civil and
criminal penalties and adverse publicity, and could harm our ability to initiate and complete clinical studies required to support regulatory applications for our proposed products. In addition, HIPAA does not replace federal, state, or other laws
that may grant individuals even greater privacy protections. We can provide no assurance that future legislation will not prevent us from generating or maintaining personal data or that patients will consent to the use of their personal information,
either of which may prevent us from undertaking or publishing essential research. These burdens or risks may prove too great for us to reasonably bear, and may adversely affect our ability to achieve profitability or maintain profitably in the
future.
Our therapeutic product candidates for which we intend to seek approval as biological products may face competition sooner than expected.
With the enactment of the Biologics Price Competition and Innovation Act of 2009, or BPCIA, as part of the Health Care Reform Law,
an abbreviated pathway for the approval of biosimilar and interchangeable biological products was created. The new abbreviated regulatory pathway establishes legal authority for the FDA to review and approve biosimilar biologics, including the
possible designation of a biosimilar as "interchangeable." The FDA defines an interchangeable biosimilar as a product that, in terms of safety or diminished efficacy, presents no greater risk when switching between the biosimilar and its
reference product than the risk of using the reference product alone. Under the BPCIA, an application for a biosimilar product cannot be submitted to the FDA until four years, or approved by the FDA until 12 years, after the original brand
product identified as the reference product was approved under a BLA. The new law is complex and is only beginning to be interpreted by the FDA. As a result, its ultimate impact, implementation and meaning are subject to uncertainty. While it is
uncertain when any such processes may be fully adopted by the FDA, any such processes could have a material adverse effect on the future commercial prospects for our biological products.
19
Table of Contents
We believe that if any of our product candidates were to be approved as biological products under
a BLA, such approved products should qualify for the 12-year period of exclusivity. However, there is a risk that the U. S. Congress could amend the BPCIA to significantly shorten this exclusivity period as proposed by President Obama, potentially
creating the opportunity for generic competition sooner than anticipated. Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of our reference products in a way that is similar to traditional generic
substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing. In addition, a competitor could decide to forego the biosimilar route and submit a full BLA after
completing its own preclinical studies and clinical trials. In such cases, any exclusivity to which we may be eligible under the BPCIA would not prevent the competitor from marketing its product as soon as it is approved.
We may be exposed to liability claims associated with the use of hazardous materials and chemicals.
Our research and development activities may involve the controlled use of hazardous materials and chemicals. Although we believe that our
safety procedures for using, storing, handling and disposing of these materials comply with federal, state and local laws and regulations, we cannot completely eliminate the risk of accidental injury or contamination from these materials. In the
event of such an accident, we could be held liable for any resulting damages and any liability could materially adversely affect our business, financial condition and results of operations. We do not currently maintain hazardous materials insurance
coverage. In addition, the federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous or radioactive materials and waste products may require us to incur substantial compliance costs
that could materially harm our business.
If we are unable to retain and recruit qualified scientists and advisors, or if any of our key executives,
key employees or key consultants discontinues his or her employment or consulting relationship with us, it may delay our development efforts or otherwise harm our business.
We may not be able to attract or retain qualified management and scientific and clinical personnel in the future due to the intense competition
for qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in the San Diego, California area. Our industry has experienced a high rate of turnover of management personnel in recent years. If we are not able
to attract, retain and motivate necessary personnel to accomplish our business objectives, we may experience constraints that will significantly impede the successful development of any product candidates, our ability to raise additional capital and
our ability to implement our overall business strategy.
We are highly dependent on key members of our management and scientific staff,
especially Henry Ji, Ph.D, Chief Executive Officer and President, Vuong Trieu, Ph.D., Chief Scientific Officer, David Miao, Chief Technology Officer, George Uy, Chief Commercial Officer and Richard Vincent, Chief Financial Officer. Our success also
depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level, and senior managers as well as junior, mid-level, and senior scientific and medical personnel. The loss of any of our executive officers, key
employees or key consultants and our inability to find suitable replacements could impede the achievement of our research and development objectives, potentially harm our business, financial condition and prospects. Furthermore, recruiting and
retaining qualified scientific personnel to perform research and development work in the future is critical to our success. We may be unable to attract and retain personnel on acceptable terms given the competition among biotechnology,
biopharmaceutical and health care companies, universities and non-profit research institutions for experienced scientists. Certain of our current officers, directors, scientific advisors and/or consultants or certain of the officers, directors,
scientific advisors and/or consultants hereafter appointed may from time to time serve as officers, directors, scientific advisors and/or consultants of other biopharmaceutical or biotechnology companies. We do not maintain "key man"
insurance policies on any of our officers or employees. All of our employees are employed "at will" and, therefore, each employee may leave our employment at any time.
We may not be able to attract or retain qualified management and scientific personnel in the future due to the intense competition for a
limited number of qualified personnel among biopharmaceutical, biotechnology, pharmaceutical and other businesses. Many of the other pharmaceutical companies that we compete against for qualified personnel have greater financial and other resources,
different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high quality candidates than
what we have to offer. If we are unable to continue to attract and retain high quality personnel, the rate and success at which we can develop and commercialize product candidates will be limited.
20
Table of Contents
We plan to grant stock options or other forms of equity awards in the future as a method of
attracting and retaining employees, motivating performance and aligning the interests of employees with those of our stockholders. If we are unable to implement and maintain equity compensation arrangements that provide sufficient incentives, we may
be unable to retain our existing employees and attract additional qualified candidates. If we are unable to retain our existing employees, including qualified scientific personnel, and attract additional qualified candidates, our business and
results of operations could be adversely affected.
Our employees may engage in misconduct or other improper activities, including noncompliance
with regulatory standards and requirements, which could have a material adverse effect on our business.
We are exposed to the risk
of employee fraud or other misconduct. Misconduct by employees could include intentional failures to comply with FDA regulations, provide accurate information to the FDA, comply with manufacturing standards we have established, comply with federal
and state health-care fraud and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject
to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission,
customer incentive programs and other business arrangements. Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our
reputation. We have adopted a Code of Business Conduct and Ethics, but it is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown
or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not
successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of operations, including the imposition of significant fines or other sanctions.
We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws and health information privacy and
security laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.
If we
obtain FDA approval for any of our product candidates and begin commercializing those products in the U.S., our operations may be directly, or indirectly through our customers, subject to various federal and state fraud and abuse laws, including,
without limitation, the federal Anti-Kickback Statute and the federal False Claims Act. These laws may impact, among other things, our proposed sales, marketing and education programs. In addition, we may be subject to patient privacy regulation by
both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include:
•
the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, to induce, or in return for,
the purchase or recommendation of an item or service reimbursable under a federal healthcare program, such as the Medicare and Medicaid programs;
•
federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from
Medicare, Medicaid, or other third-party payers that are false or fraudulent;
•
the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created new federal criminal statutes that prohibit executing a scheme to defraud any healthcare benefit program and making false
statements relating to healthcare matters;
•
HIPAA, as amended by the Health Information Technology and Clinical Health Act, or HITECH, and its implementing regulations, which imposes certain requirements relating to the privacy, security and transmission of
individually identifiable health information; and
•
state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payer, including commercial insurers, and state
laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.
If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we
may be subject to penalties, including civil and criminal penalties, damages, fines and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be
required to limit commercialization of our product candidates.
We face an inherent risk of product liability as a result of the
clinical testing of our product candidates and will face an even greater risk if we commercialize any products. For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during product
testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability, and a breach of
warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our
product candidates, if approved. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:
•
decreased demand for our product candidates or products that we may develop;
•
injury to our reputation;
•
withdrawal of clinical trial participants;
•
initiation of investigations by regulators;
•
costs to defend the related litigation;
•
a diversion of management's time and our resources;
•
substantial monetary awards to trial participants or patients;
•
product recalls, withdrawals or labeling, marketing or promotional restrictions;
•
loss of revenues from product sales; and
•
the inability to commercialize our product candidates.
Our inability to obtain and retain
sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of products we develop.
We will need to increase the size of our company and may not effectively manage our growth.
Our success will depend upon growing our business and our employee base. Over the next 12 months, we plan to add additional employees to assist
us with research and development. Our future growth, if any, may cause a significant strain on our management, and our operational, financial and other resources. Our ability to manage our growth effectively will require us to implement and improve
our operational, financial and management systems and to expand, train, manage and motivate our employees. These demands may require the hiring of additional management personnel and the development of additional expertise by management. Any
increase in resources devoted to research and product development without a corresponding increase in our operational, financial and management systems could have a material adverse effect on our business, financial condition, and results of
operations.
Any disruption in our research and development facilities could adversely affect our business, financial condition and results of
operations.
Our principal executive offices, which house our research and development programs, are located in San Diego,
California. Our facilities may be affected by natural or man-made disasters. Earthquakes are of particular significance since our facilities are located in an earthquake-prone area. We are also vulnerable to damage from other types of disasters,
including power loss, attacks from extremist organizations, fire, floods and similar events. In the event that our facilities were affected by a natural or man-made disaster, we may be forced to curtail our operations and/or rely on third-parties to
perform some or all of our research and development activities. Although we believe we possess adequate insurance for damage to our property and the disruption of our business from casualties, such insurance may not be sufficient to cover all of our
potential losses and may not continue to be available to us on acceptable terms, or at all. In the future, we may choose to expand our operations in either our existing facilities or in new facilities. If we expand our worldwide manufacturing
locations, there can be no assurance that this expansion will occur without implementation difficulties, or at all.
International operations may
expose us to foreign currency exchange rate fluctuations for all foreign currencies in which we do business and we may be materially adversely affected by these fluctuations.
We formed Sorrento Hong Kong effective December 4, 2012. Sorrento Hong Kong had no operations in 2012. In the event Sorrento Hong Kong
becomes operational, we may have an international subsidiary that operates in a foreign currency which would expose us to foreign currency exchange rate fluctuations. We intend to hedge any foreign currency risks associated with potential
transactions by entering into forward contracts. Although we may enter into such forward contracts, they may not be adequate to eliminate the risk of foreign currency exchange rate exposures. International operations may also expose us to currency
fluctuations as we translate the financial statements of our international subsidiary to U.S. Dollars.

Our business and operations would suffer in the event of system failures.
Despite the implementation of security measures, our internal computer systems and those of our CROs and other contractors and consultants are
vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we have not experienced any such system failure, accident or security breach to date, if such an
event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result
in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or
inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development of our product candidates could be delayed.
If we acquire companies or technologies in the future, they could prove difficult to integrate, disrupt our business, dilute stockholder value, and
adversely affect our operating results and the value of our common stock.
As part of our business strategy, we may acquire, enter
into joint ventures with, or make investments in complementary or synergistic companies, services, and technologies in the future. Acquisitions and investments involve numerous risks, including:
•
difficulties in identifying and acquiring products, technologies, or businesses that will help our business;
•
difficulties in integrating operations, technologies, services, and personnel;
•
diversion of financial and managerial resources from existing operations;
•
the risk of entering new development activities and markets in which we have little to no experience;
•
risks related to the assumption of known and unknown liabilities; and
•
risks related to our ability to raise sufficient capital to fund additional operating activities.
As a result, if we fail to properly evaluate acquisitions or investments, we may not achieve the anticipated benefits of any such
acquisitions, we may incur costs in excess of what we anticipate, and management resources and attention may be diverted from other necessary or valuable activities.
The terms of our secured debt facility require us to meet certain operating and financial covenants and place restrictions on our operating and
financial flexibility. If we raise additional capital through debt financing, the terms of any new debt could further restrict our ability to operate our business.
Effective in March 2014, as amended and restated, we have a $12.5 million loan and security agreement with Oxford Finance LLC, or Oxford,
and Silicon Valley Bank, or SVB, that is secured by a lien covering substantially all of our assets, excluding intellectual property. As of December 31, 2013, under our initial $5.0 million loan and security agreement with Oxford and SVB
entered into in September 2013, we had an outstanding principal balance of $5.0 million. The amended and restated loan and security agreement contains customary affirmative and negative covenants and events of default. The affirmative covenants
include, among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports and maintain insurance coverage. The negative covenants include, among others, restrictions on transferring
collateral, changing our business, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments and creating other liens on our assets, in each case subject to customary
exceptions. If we default under the loan agreement, the lenders may accelerate all of our repayment obligations and take control of our pledged assets, potentially requiring us to renegotiate our agreement on terms less favorable to us or to
immediately cease operations. Further, if we are liquidated, the lender's right to repayment would be senior to the rights of the holders of our common stock to receive any proceeds from the liquidation. The lenders could declare a default upon
the occurrence of any event that they interpret as a material adverse change as defined under the loan agreement, thereby requiring us to repay the loan immediately or to attempt to reverse the declaration of default through negotiation or
litigation. Any declaration by the lenders of an event of default could significantly harm our business and prospects and could cause the price of our common stock to decline. If we raise any additional debt financing, the terms of such additional
debt could further restrict our operating and financial flexibility.

Risks Related to the Acquisitions of IgDraSol, Sherrington and Concortis
We may fail to realize the anticipated benefits of the acquisitions of IgDraSol, Sherrington and Concortis.
The success of the acquisitions of IgDraSol, Sherrington and Concortis will depend on, among other things, our ability to combine our
businesses in a manner that does not materially disrupt existing relationships and that allows us to achieve development and operational synergies. If we are unable to achieve these objectives, the anticipated benefits of the acquisition may not be
realized fully or at all or may take longer to realize than expected. In particular, the acquisition may not be accretive to our stock value or development pipeline in the near or long term.
It is possible that the integration process could result in the loss of key employees; the disruption of our ongoing business or the ongoing
business of the acquired companies; or inconsistencies in standards, controls, procedures, or policies that could adversely affect our ability to maintain relationships with third parties and employees or to achieve the anticipated benefits of the
acquisition. Integration efforts between the two companies will also divert management's attention from our core business and other opportunities that could have been beneficial to our shareholders. An inability to realize the full extent of,
or any of, the anticipated benefits of the acquisition, as well as any delays encountered in the integration process, could have an adverse effect on our business and results of operations, which may affect the value of the shares of our common
stock after the completion of the acquisition. If we are unable to achieve these objectives, the anticipated benefits of the acquisition may not be realized fully or at all or may take longer to realize than expected. In particular, the acquisition
may not be accretive to our stock value or development pipeline in the near or long term.
We expect to incur significant additional costs in
connection with the acquisition of IgDraSol, Sherrington and Concortis and integrating the companies into a single business.
During 2013, we incurred significant legal and professional fees in connection with such acquisitions. We expect to incur additional costs
integrating the companies' operations, higher development and regulatory costs, and personnel, which cannot be estimated accurately at this time. If the total costs of the integration of our companies and advancement of the Cynviloq, RTX or
Concortis assets exceed the anticipated benefits of the acquisition, our financial results could be adversely affected.
Risks Related to Our
Intellectual Property
Our ability to protect our intellectual property rights will be critically important to the success of our business, and
we may not be able to protect these rights in the U.S. or abroad.
Our success, competitive position and future revenues will
depend in part on our ability to obtain and maintain patent protection for our product candidates, methods, processes and other technologies, to prevent third parties from infringing on our proprietary rights and to operate without infringing upon
the proprietary rights of third parties. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary rights are covered by valid and enforceable patents or are effectively
maintained as trade secrets. We attempt to protect our proprietary position by maintaining trade secrets and by filing U.S. and foreign patent applications related to our proprietary technology, inventions and improvements that are important to the
development of our business. We have one issued U.S. patent covering our G-MAB
®
which expires in 2022 and the examination of its European equivalent is currently in progress. In 2011, several
improvement patent applications were filed for our proprietary antibody library technology. In 2013, we filed 14 antibody family patents. In 2013, we filed three patent application families for the Concortis conjugation chemistry. However, due to
the difficulties of enforcing such antibody library technology, we filed a key patent application in the U.S. only and requested nonpublication. We have commenced generating a patent application portfolio of patents to protect each product candidate
in our pipeline. However, the patent position of biopharmaceutical companies involves complex legal and factual questions, and therefore we cannot predict with certainty whether any patent applications that we have filed or that we may file in the
future will be approved or any resulting patents will be enforced. In addition, third parties may challenge, seek to invalidate or circumvent any of our patents, once they are issued. Thus, any patents that we own or license from third parties may
not provide any protection against competitors. Any patent applications that we have filed or that we may file in the future, or those we may license from third parties, may not result in patents being issued. Also, patent rights may not provide us
with adequate proprietary protection or competitive advantages against competitors with similar technologies.
In addition, the laws of
certain foreign countries do not protect our intellectual property rights to the same extent as do the laws of the U.S. If we fail to apply for intellectual property protection or if we cannot adequately protect our intellectual property rights in
these foreign countries, our competitors may be able to compete more effectively against us, which could adversely affect our competitive position, as well as our business, financial condition and results of operations.
The intellectual property protection for Cynviloq is being managed and controlled by Sanyang, the manufacturer.
We do not manage or control the intellectual property protection for Cynviloq. Therefore we cannot provide any assurance that the 3 patent
applications in the U.S. or the AU will ever issue or be granted. Moreover, there cannot be any assurances that the families of patent applications that could provide product protection for Cynviloq will ever issue or be granted, or even provide
meaningful protection to prevent generic Cynviloq protection.

If any of our trade secrets, know-how or other proprietary information is disclosed, the value of our trade
secrets, know-how and other proprietary rights would be significantly impaired and our business and competitive position would suffer.
Our success also depends upon the skills, knowledge and experience of our scientific and technical personnel and our consultants and advisors,
as well as our licensors. To help protect our proprietary know-how and our inventions for which patents may be unobtainable or difficult to obtain, we rely on trade secret protection and confidentiality agreements. Unlike some of our competitors, we
maintain our proprietary libraries for ourselves as we believe they have proven to be superior in obtaining strong binder product candidates. To this end, we require all of our employees, consultants, advisors and contractors to enter into
agreements which prohibit the disclosure of confidential information and, where applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business. These agreements may not provide
adequate protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure or the lawful development by others of such information. If any of our trade secrets, know-how or other
proprietary information is disclosed, the value of our trade secrets, know-how and other proprietary rights would be significantly impaired and our business and competitive position would suffer.
Third party competitors may seek to challenge the validity of our patents, thereby rendering them unenforceable or we may seek to challenge
third party competitor patents if such third parties seek to interpret or enforce a claim scope going well beyond the actual enabled invention.
Claims that we infringe upon the rights of third parties may give rise to costly and lengthy litigation, and we could be prevented from selling
products, forced to pay damages, and defend against litigation.
Third parties may assert patent or other intellectual property
infringement claims against us or our strategic partners or licensees with respect to our technologies and potential product candidates. If our products, methods, processes and other technologies infringe upon the proprietary rights of other
parties, we could incur substantial costs and we may have to:
•
obtain licenses, which may not be available on commercially reasonable terms, if at all, and may be non-exclusive, thereby giving our competitors access to the same intellectual property licensed to us;
•
redesign our products or processes to avoid infringement;
•
stop using the subject matter validly claimed in the patents held by others;
•
pay damages; and
•
defend litigation or administrative proceedings which may be costly whether we win or lose, and which could result in a substantial diversion of our valuable management resources.
Even if we were to prevail, any litigation could be costly and time-consuming and would divert the attention of our management and key
personnel from our business operations. Furthermore, as a result of a patent infringement suit brought against us or our strategic partners or licensees, we or our strategic partners or licensees may be forced to stop or delay developing,
manufacturing or selling technologies or potential products that are claimed to infringe a third party's intellectual property unless that party grants us or our strategic partners' or licensees' rights to use its intellectual
property. Ultimately, we may be unable to develop some of our technologies or potential products or may have to discontinue development of a product candidate or cease some of our business operations as a result of patent infringement claims, which
could severely harm our business.
Our position as a relatively small company may cause us to be at a significant disadvantage in defending our
intellectual property rights and in defending against infringement claims by third parties.
Litigation relating to the ownership
and use of intellectual property is expensive, and our position as a relatively small company in an industry dominated by very large companies may cause us to be at a significant disadvantage in defending our intellectual property rights and in
defending against claims that our technology infringes or misappropriates third party intellectual property rights. However, we may seek to use various post-grant administrative proceedings, including new procedures created under the America Invents
Act, to invalidate potentially overly-broad third party rights. Even if we are able to defend our position, the cost of doing so may adversely affect our ability to grow, generate revenue or become profitable. Although we have not yet experienced
patent litigation, we may in the future be subject to such litigation and may not be able to protect our intellectual property at a reasonable cost, or at all, if such litigation is initiated. The outcome of litigation is always uncertain, and in
some cases could include judgments against us that require us to pay damages, enjoin us from certain activities or otherwise affect our legal or contractual rights, which could have a significant adverse effect on our business.

Third-party claims of intellectual property infringement may prevent or delay our drug discovery and
development efforts.
Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of
third parties. There is a substantial amount of litigation involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including Patent Office administrative proceedings, such as inter parties reviews,
and reexamination proceedings before the U.S. PTO or oppositions and revocations and other comparable proceedings in foreign jurisdictions. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third
parties, exist in the fields in which we are developing product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates may give rise to claims of infringement
of the patent rights of others.
Despite safe harbor provisions, third parties may assert that we are employing their proprietary
technology without authorization. There may be third-party patents, of which we are currently unaware, with claims to materials, formulations, methods of doing research or library screening, methods of manufacture or methods for treatment related to
the use or manufacture of our product candidates. Because patent applications can take many years to issue, there may be currently pending patent published applications which may later result in issued patents that our product candidates may
infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process
of any of our product candidates, any molecules formed during the manufacturing process or any final product itself, the holders of any such patents may be able to block our ability to commercialize such product candidate unless we obtain a license
under the applicable patents, or until such patents expire or they are finally determined to be held invalid or unenforceable. Similarly, if any third-party patent were held by a court of competent jurisdiction to cover aspects of our formulations,
processes for manufacture or methods of use, including combination therapy or patient selection methods, the holders of any such patent may be able to block our ability to develop and commercialize the applicable product candidate unless we obtain a
license, limit our uses, or until such patent expires or is finally determined to be held invalid or unenforceable. In either case, such a license may not be available on commercially reasonable terms or at all.
Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop
and commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a
successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys' fees for willful infringement, obtain one or more licenses from third parties, limit our uses, pay royalties or
redesign our infringing product candidates, which may be impossible or require substantial time and monetary expenditure. We cannot predict whether any such license would be available at all or whether it would be available on commercially
reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our product candidates. We may fail to obtain any of these licenses at a
reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our product candidates, which could harm our business significantly.
We may not be able to protect our intellectual property rights throughout the world.
Filing, prosecuting and defending patents on all of our product candidates throughout the world would be prohibitively expensive. Competitors
may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as
strong as that in the U.S. These products may compete with our products in jurisdictions where we do not have any issued patents and our patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so
competing.
Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign
jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biopharmaceuticals, which could make
it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and
divert our efforts and attention from other aspects of our business.
Confidentiality agreements with employees and others may not adequately
prevent disclosure of our trade secrets and other proprietary information and may not adequately protect our intellectual property, which could limit our ability to compete.
Because we operate in the highly technical field of research and development of small molecule drugs, we rely in part on trade secret
protection in order to protect our proprietary trade secrets and unpatented know-how. However, trade secrets are difficult to
26
Table of Contents
protect, and we cannot be certain that others will not develop the same or similar technologies on their own. We have taken steps, including entering into confidentiality agreements with our
employees, consultants, outside scientific collaborators, sponsored researchers and other advisors, to protect our trade secrets and unpatented know-how. These agreements generally require that the other party keep confidential and not disclose to
third parties all confidential information developed by the party or made known to the party by us during the course of the party's relationship with us. We also typically obtain agreements from these parties which provide that inventions
conceived by the party in the course of rendering services to us will be our exclusive property. However, these agreements may not be honored and may not effectively assign intellectual property rights to us. Enforcing a claim that a party illegally
obtained and is using our trade secrets or know-how is difficult, expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the U.S. may be less willing to protect trade secrets or know-how. The failure to obtain or
maintain trade secret protection could adversely affect our competitive position.
If we breach any of the agreements under which we license
commercialization rights to our product candidates from third parties, we could lose license rights that are important to our business.
We license the use, development and commercialization rights for all of our product candidates, and may enter into similar licenses in the
future. Under each of our existing license agreements we are subject to commercialization and development, diligence obligations, milestone payment obligations, royalty payments and other obligations. If we fail to comply with any of these
obligations or otherwise breach our license agreements, our licensing partners may have the right to terminate the license in whole or in part.
Generally, the loss of any one of our three current licenses or other licenses in the future could materially harm our business, prospects,
financial condition and results of operations.
Intellectual property rights do not necessarily address all potential threats to our competitive
advantage.
The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property
rights have limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:
•
Others may be able to make compounds that are similar to our product candidates but that are not covered by the claims of the patents that we own or have exclusively licensed.
•
We or our licensors or strategic partners might not have been the first to make the inventions covered by the issued patent or pending patent application that we own or have exclusively licensed.
•
We or our licensors or strategic partners might not have been the first to file patent applications covering certain of our inventions.
•
Others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights.
•
It is possible that our pending patent applications will not lead to issued patents.
•
Issued patents that we own or have exclusively licensed may not provide us with any competitive advantages, or may be held invalid or unenforceable, as a result of legal challenges by our competitors.
•
Our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned from such activities to develop competitive products for sale in our
major commercial markets.
•
We may not develop additional proprietary technologies that are patentable.
•
The patents of others may have an adverse effect on our business.
Should any of these events
occur, they could significantly harm our business, results of operations and prospects.
From time to time we may need to license patents,
intellectual property and proprietary technologies from third parties, which may be difficult or expensive to obtain.
We may need
to obtain licenses to patents and other proprietary rights held by third parties to successfully develop, manufacture and market our drug products. As an example, it may be necessary to use a third party's proprietary technology to reformulate
one of our drug products in order to improve upon the capabilities of the drug product. If we are unable to timely obtain these licenses on reasonable terms, our ability to commercially exploit our drug products may be inhibited or prevented.

Risks Related to Ownership of Our Common Stock
The market price of our common stock may fluctuate significantly, and investors in our common stock may lose all or a part of their investment.
The market prices for securities of biotechnology and pharmaceutical companies have historically been highly volatile, and the
market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. The market price of our common stock may fluctuate significantly in response to numerous
factors, some of which are beyond our control, such as:
•
actual or anticipated adverse results or delays in our clinical trials;
•
our failure to commercialize our product candidates, if approved;
•
unanticipated serious safety concerns related to the use of any of our product candidates;
•
adverse regulatory decisions;
•
changes in laws or regulations applicable to our product candidates, including but not limited to clinical trial requirements for approvals;
•
legal disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our product candidates, government investigations and the
results of any proceedings or lawsuits, including patent or stockholder litigation;
•
our decision to initiate a clinical trial, not initiate a clinical trial or to terminate an existing clinical trial;
•
our dependence on third parties, including CROs;
•
announcements of the introduction of new products by our competitors;
•
market conditions in the pharmaceutical and biotechnology sectors;
•
announcements concerning product development results or intellectual property rights of others;
•
future issuances of common stock or other securities;
•
the addition or departure of key personnel;
•
failure to meet or exceed any financial guidance or expectations regarding development milestones that we may provide to the public;
•
actual or anticipated variations in quarterly operating results;
•
our failure to meet or exceed the estimates and projections of the investment community;
•
overall performance of the equity markets and other factors that may be unrelated to our operating performance or the operating performance of our competitors, including changes in market valuations of similar
companies;
•
conditions or trends in the biotechnology and biopharmaceutical industries;
•
introduction of new products offered by us or our competitors;
•
announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments by us or our competitors;
•
issuances of debt or equity securities;
•
sales of our common stock by us or our stockholders in the future;
•
trading volume of our common stock;
•
ineffectiveness of our internal controls;
•
publication of research reports about us or our industry or positive or negative recommendations or withdrawal of research coverage by securities analysts;
•
general political and economic conditions;
•
effects of natural or man-made catastrophic events; and
•
other events or factors, many of which are beyond our control.
Further, the equity markets in
general have recently experienced extreme price and volume fluctuations. Continued market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock. Price
volatility of our common stock might worsen if the trading volume of our common stock is low. The realization of any of the above risks or any of a broad range of other risks, including those described in these "Risk Factors," could have a
dramatic and material adverse impact on the market price of our common stock.

Table of Contents
We have not paid cash dividends in the past and do not expect to pay cash dividends in the foreseeable
future. Any return on investment may be limited to the value of our common stock.
We have never paid cash dividends on our common
stock and do not anticipate paying cash dividends on our common stock in the foreseeable future. The payment of dividends on our capital stock will depend on our earnings, financial condition and other business and economic factors affecting us at
such time as the board of directors may consider relevant. If we do not pay dividends, our common stock may be less valuable because a return on your investment will only occur if the common stock price appreciates.
A sale of a substantial number of shares of the common stock may cause the price of our common stock to decline.
If our stockholders sell, or the market perceives that our stockholders intend to sell for various reasons, substantial amounts of our common
stock in the public market, including shares issued in connection with the exercise of outstanding options or warrants, the market price of our common stock could fall. Sales of a substantial number of shares of our common stock may make it more
difficult for us to sell equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate. We may become involved in securities class action litigation that could divert management's attention and
harm our business.
The stock markets have from time to time experienced significant price and volume fluctuations that have affected the
market prices for the common stock of biotechnology and biopharmaceutical companies. These broad market fluctuations may cause the market price of our common stock to decline. In the past, securities class action litigation has often been brought
against a company following a decline in the market price of our securities. This risk is especially relevant for us because biotechnology and biopharmaceutical companies have experienced significant stock price volatility in recent years. We may
become involved in this type of litigation in the future. Litigation often is expensive and diverts management's attention and resources, which could adversely affect our business.
Our quarterly operating results may fluctuate significantly.
We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results will be affected by numerous
factors, including:
•
variations in the level of expenses related to our development programs;
•
the addition or termination of clinical trials;
•
any intellectual property infringement lawsuit in which we may become involved;
•
regulatory developments affecting our product candidates;
•
our execution of any collaborative, licensing or similar arrangements, and the timing of payments we may make or receive under these arrangements; and
•
if Cynviloq receives regulatory approval, the level of underlying demand for that product and wholesalers' buying patterns
If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could
decline substantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our common stock to fluctuate substantially.
Existing stockholders' interest in us may be diluted by additional issuances of equity securities and raising funds through lending and licensing
arrangements may restrict our operations or require us to relinquish proprietary rights.
We may issue additional equity securities
to fund future expansion and pursuant to employee benefit plans. We may also issue additional equity for other purposes. These securities may have the same rights as our common stock or, alternatively, may have dividend, liquidation or other
preferences to our common stock. The issuance of additional equity securities will dilute the holdings of existing stockholders and may reduce the share price of our common stock.

If we raise additional funds through collaboration, licensing or other similar arrangements, it
may be necessary to relinquish potentially valuable rights to our product candidates, potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. If adequate funds are not available, our ability to
achieve profitability or to respond to competitive pressures would be significantly limited and we may be required to delay, significantly curtail or eliminate the development of our product candidates.
Directors, executive officers, principal stockholders and affiliated entities own a significant percentage of our capital stock, and they may make
decisions that you do not consider to be in your best interests or those of our other stockholders.
As of March 31, 2014, our
directors, executive officers and principal stockholders beneficially owned, in the aggregate, approximately 36.7% of our outstanding voting securities. As a result, if some or all of them acted together, they would have the ability to exert
substantial influence over the election of our board of directors and the outcome of issues requiring approval by our stockholders. This concentration of ownership may also have the effect of delaying or preventing a change in control of our company
that may be favored by other stockholders. This could prevent transactions in which stockholders might otherwise recover a premium for their shares over current market prices.
Our ability to use our net operating loss carry forwards may be subject to limitation.
Generally, a change of more than 50% in the ownership of a company's stock, by value, over a three-year period constitutes an ownership
change for U.S. federal income tax purposes. An ownership change may limit our ability to use our net operating loss carryforwards attributable to the period prior to the change. As a result, if we earn net taxable income, our ability to use our
pre-change net operating loss carryforwards to offset U.S. federal taxable income may become subject to limitations, which could potentially result in increased future tax liability for us. At December 31, 2013, we had net operating loss
carryforwards aggregating approximately $28.1 million.
Our certificate of incorporation, as amended, and bylaws provide for indemnification of
officers and directors at our expense and limits their liability, which may result in a major cost to us and hurt the interests of our stockholders because corporate resources may be expended for the benefit of our officers and/or directors.
Our certificate of incorporation, as amended, bylaws and applicable Delaware law provide for the indemnification of our directors,
officers, employees, and agents, under certain circumstances, against attorney's fees and other expenses incurred by them in any litigation to which they become a party arising from their association with or activities on our behalf. We will
also bear the expenses of such litigation for any of our directors, officers, employees, or agents, upon such person's promise to repay us, therefore if it is ultimately determined that any such person shall not have been entitled to
indemnification. This indemnification policy could result in substantial expenditures by us, which we will be unable to recover.
Our corporate
documents and Delaware law contain provisions that could discourage, delay or prevent a change in control of our company, prevent attempts to replace or remove current management and reduce the market price of our common stock.
Provisions in our certificate of incorporation, as amended, and bylaws may discourage, delay or prevent a merger or acquisition involving us
that our stockholders may consider favorable. For example, our certificate of incorporation, as amended, authorizes our board of directors to issue up to 100,000,000 shares of "blank check" preferred stock. As a result, without further
stockholder approval, the board of directors has the authority to attach special rights, including voting and dividend rights, to this preferred stock. With these rights, preferred stockholders could make it more difficult for a third party to
acquire us.
We are also subject to the anti-takeover provisions of the Delaware General Corporation Law. Under these provisions, if
anyone becomes an "interested stockholder," we may not enter into a "business combination" with that person for three years without special approval, which could discourage a third party from making a takeover offer and could
delay or prevent a change in control of us. An "interested stockholder" means, generally, someone owning 15% or more of our outstanding voting stock or an affiliate of ours that owned 15% or more of our outstanding voting stock during the
past three years, subject to certain exceptions as described in the Delaware General Corporation Law.
We have adopted a shareholder
rights plan, the purpose of which is, among other things, to enhance our board's ability to protect shareholder interests and to ensure that shareholders receive fair treatment in the event any coercive takeover attempt of our company is made
in the future. The shareholder rights plan could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, our company or a large block of our common stock.

Compliance with changing regulations concerning corporate governance and public disclosure may result in
additional expenses.
There have been changing laws, regulations and standards relating to corporate governance and public
disclosure, including the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley, new regulations promulgated by the SEC and rules promulgated by the national securities
exchanges. The Dodd-Frank Act, enacted in July 2010, expands federal regulation of corporate governance matters and imposes requirements on public companies to, among other things, provide stockholders with a periodic advisory vote on executive
compensation and also adds compensation committee reforms and enhanced pay-for-performance disclosures. While some provisions of the Dodd-Frank Act are effective upon enactment, others will be implemented upon the SEC's adoption of related
rules and regulations. The scope and timing of the adoption of such rules and regulations is uncertain and, accordingly, the cost of compliance with the Dodd-Frank Act is also uncertain.
These new or changed laws, regulations and standards are, or will be, subject to varying interpretations in many cases due to their lack of
specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated
by ongoing revisions to disclosure and governance practices. As a result, our efforts to comply with evolving laws, regulations and standards are likely to continue to result in increased general and administrative expenses and a diversion of
management time and attention from revenue-generating activities to compliance activities. Members of our board of directors and our principal executive officer and principal financial officer could face an increased risk of personal liability in
connection with the performance of their duties. As a result, we may have difficulty attracting and retaining qualified directors and executive officers, which could harm our business. If the actions we take in our efforts to comply with new or
changed laws, regulations and standards differ from the actions intended by regulatory or governing bodies, we could be subject to liability under applicable laws or our reputation may be harmed.
If we fail to comply with the rules under the Sarbanes-Oxley Act of 2002 related to accounting controls and procedures, or, if we discover material
weaknesses and deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult.
Sarbanes-Oxley specifically requires, among other things, that we maintain effective internal controls for financial reporting and disclosure
of controls and procedures. In particular, we must perform system and process evaluation and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial
reporting, as required by Section 404 of Sarbanes-Oxley. Our testing, or the subsequent testing by our independent registered public accounting firm, if and when required, may reveal deficiencies in our internal controls over financial
reporting that are deemed to be material weaknesses. Our compliance with Section 404 will require that we incur substantial accounting expense and expend significant management efforts. We currently do not have an internal audit group, and we
will need to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge. Moreover, if we are not able to comply with the requirements of Section 404 in a timely manner, or if we
or our independent registered public accounting firm identifies deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline, and we could be subject to
sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

SELLING STOCKHOLDERS
The selling stockholders named in this prospectus (the "Selling Stockholders") are offering 750,900 shares of our common stock including shares of
stock which are issuable to the Selling Stockholders directly by options, stock awards or indirectly through exercise of options pursuant to our 2009 Stock Incentive Plan, as amended and restated. The selling stockholders are our officers and
directors, and may be deemed to be our "affiliates," as defined in Rule 405 of the Securities Act, who may acquire such shares upon exercise of options granted under the Plan. We do not know whether any of such individuals will be
granted additional options under the Plan, whether any of such Selling Stockholders will use this prospectus in connection with the offer or sale of any shares of Common Stock, or, if this prospectus is so used, how many shares of Common Stock will
be offered or sold. The selling stockholders may resell all, a portion, or none of the shares that they may acquire pursuant to the Plan. The Selling Stockholders named in this prospectus were granted the options in consideration of
services and such shares are issuable upon exercise of stock options at various exercise prices, depending on the dates of grant.
The
following table provides, as of March 31, 2014, information regarding the beneficial ownership of our common shares held by each of the selling stockholders, including:
1.
the total number of common shares owned by each selling stockholder prior to this offering;
2.
the total number of common shares that are to be offered by each selling stockholder;
3.
the total number of common shares that will be owned by each selling stockholder upon completion of the offering; and
4.
the percentage owned by each selling stockholder, prior to and upon completion of the offering.
Information with respect to beneficial ownership is based upon information obtained from the Selling Stockholders. Information with respect to
"Shares Beneficially Owned Prior to the Offering" includes the shares issuable upon exercise of the stock options held by the selling stockholders to the extent these options are exercisable within 60 days of March 31, 2014.
Information with respect to "Shares Beneficially Owned After the Offering" assumes the sale of all of the common shares offered by this prospectus and no other purchases or sales of our common shares by the selling stockholders. Except as
described below and to our knowledge, the named selling shareholder beneficially owns and has sole voting and investment power over all common shares or rights to these common shares.
Because the Selling Stockholders may offer all or part of the shares of common stock, which they own pursuant to the offering contemplated by
this reoffer prospectus, and because its offering is not being underwritten on a firm commitment basis, no estimate can be given as to the amount of shares that will be held upon termination of this offering. The shares of common stock currently
owned offered by this reoffer prospectus may be offered from time to time by the Selling Stockholders named below. However, information with respect to "Shares Beneficially Owned Upon Completion the Offering" assumes the sale of all of the
shares of common stock offered by this prospectus and no other purchases or sales of our shares of common stock by the selling stockholders. Except as described below and to our knowledge, the named selling stockholder beneficially owns and has sole
voting and investment power over all common shares or rights to these common shares.

PLAN OF DISTRIBUTION
Timing of Sales
The selling stockholders
may offer and sell the shares covered by this prospectus at various times. The selling stockholders will act independently of our company in making decisions with respect to the timing, manner and size of each sale.
No Known Agreements to Resell the Shares
To our knowledge, no selling stockholder has any agreement or understanding, directly or indirectly, with any person to resell the common
shares covered by this prospectus.
Offering Price
The sales price offered by the selling stockholders to the public may be:
1.
the market price prevailing at the time of sale;
2.
a price related to such prevailing market price; or
3.
such other price as the selling stockholders determine from time to time.
Manner of Sale
The common shares may be sold by means of one or more of the following methods:
1.
a block trade in which the broker-dealer so engaged will attempt to sell the common shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;
2.
Purchases by a broker-dealer as principal and resale by that broker-dealer for its account pursuant to this prospectus;
3.
ordinary brokerage transactions in which the broker solicits purchasers;
4.
through options, swaps or derivatives;
5.
in transactions to cover short sales;
6.
privately negotiated transactions; or
7.
in a combination of any of the above methods.
The selling stockholders may sell their common
shares directly to purchasers or may use brokers, dealers, underwriters or agents to sell their common shares. Brokers or dealers engaged by the selling stockholders may arrange for other brokers or dealers to participate. Brokers or dealers may
receive commissions, discounts or concessions from the selling stockholders, or, if any such broker-dealer acts as agent for the purchaser of common shares, from the purchaser in amounts to be negotiated immediately prior to the sale. The
compensation received by brokers or dealers may, but is not expected to, exceed that which is customary for the types of transactions involved.
Broker-dealers may agree with a selling stockholder to sell a specified number of common shares at a stipulated price per common share, and,
to the extent the broker-dealer is unable to do so acting as agent for a selling stockholder, to purchase as principal any unsold common shares at the price required to fulfill the broker-dealer commitment to the selling stockholder.
Broker-dealers who acquire common shares as principal may thereafter resell the common shares from time to time in transactions, which may
involve block transactions and sales to and through other broker-dealers, including transactions of the nature described above, on The NASDAQ Capital Market or otherwise at prices and on terms then prevailing at the time of sale, at prices then
related to the then-current market price or in negotiated transactions. In connection with resales of the common shares, broker-dealers may pay to or receive from the purchasers of shares commissions as described above.
36
Table of Contents
If our selling stockholders enter into arrangements with brokers or dealers, as described above,
we are obligated to file a post-effective amendment to this registration statement disclosing such arrangements, including the names of any broker-dealers acting as underwriters.
The selling stockholders and any broker-dealers or agents that participate with the selling stockholders in the sale of the common shares may
be deemed to be "underwriters" within the meaning of the Securities Act. In that event, any commissions received by broker-dealers or agents and any profit on the resale of the common shares purchased by them may be deemed to be
underwriting commissions or discounts under the Securities Act.
We will make copies of this prospectus available to the selling
stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.
Sales Pursuant to Rule 144
Any common shares covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144
rather than pursuant to this prospectus.
Regulation M
The selling stockholders must comply with the requirements of the Securities Act and the Exchange Act in the offer and sale of the common
stock. In particular we will advise the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of common shares in the market and to the activities of the selling stockholders and their
affiliates. Regulation M under the Exchange Act prohibits, with certain exceptions, participants in a distribution from bidding for, or purchasing for an account in which the participant has a beneficial interest, any of the securities that are
the subject of the distribution.
Accordingly, during such times as a selling stockholder may be deemed to be engaged in a distribution of
the common stock, and therefore be considered to be an underwriter, the selling stockholder must comply with applicable law and, among other things:
1.
may not engage in any stabilization activities in connection with our common stock;
2.
may not cover short sales by purchasing shares while the distribution is taking place; and
3.
may not bid for or purchase any of our securities or attempt to induce any person to purchase any of our securities other than as permitted under the Exchange Act.
State Securities Laws
Under the
securities laws of some states, the common shares may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the common shares may not be sold unless the shares have been registered or qualified
for sale in the state or an exemption from registration or qualification is available and is complied with.
Expenses of Registration
We are bearing all costs relating to the registration of the common stock. These expenses are estimated to be $5,000, including, but not
limited to, legal, accounting, printing and mailing fees. The selling stockholders, however, will pay any commissions or other fees payable to brokers or dealers in connection with any sale of the common stock.

deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or
supersedes such earlier statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION
FOR SECURITIES ACT LIABILITIES
As permitted by the Delaware General Corporation Law, we have adopted provisions in our certificate of incorporation and
by-laws
to be in effect at the closing of this offering that limit or eliminate the personal liability of our directors. Consequently, a director will not be personally liable to us or our stockholders for monetary
damages or breach of fiduciary duty as a director, except for liability for:
•
any breach of the director's duty of loyalty to us or our stockholders;
•
any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
•
any unlawful payments related to dividends or unlawful stock repurchases, redemptions or other distributions; or
38
Table of Contents
•
any transaction from which the director derived an improper personal benefit.
These
limitations of liability do not alter director liability under the federal securities laws and do not affect the availability of equitable remedies such as an injunction or rescission.
In addition, our by-laws provide that:
•
we will indemnify our directors, officers and, in the discretion of our board of directors, certain employees to the fullest extent permitted by the Delaware General Corporation Law; and
•
we will advance expenses, including attorneys' fees, to our directors and, in the discretion of our board of directors, to our officers and certain employees, in connection with legal proceedings, subject to
limited exceptions.
We also maintain general liability insurance that covers certain liabilities of our directors and
officers arising out of claims based on acts or omissions in their capacities as directors or officers, including liabilities under the Securities Act.
These provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These
provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder's
investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. We believe that these provisions, the indemnification agreements and the
insurance are necessary to attract and retain talented and experienced directors and officers.
Insofar as indemnification for liabilities
arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered,
the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or
supersedes such earlier statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of
Named Experts and Counsel.
No expert or counsel named in this Registration Statement as having prepared or certified any part of this
Registration Statement or having given an opinion upon the validity of the securities being registered or upon other legal matters in connection with the registration or offering of the common stock was employed on a contingency basis or had, or is
to receive, in connection with the offering, a substantial interest, directly or indirectly, in the registrant or any of its parents or subsidiaries.
Item 6. Indemnification of Directors and Officers.
Section 145 ("Section 145") of the Delaware General Corporation Law, as amended (the "DGCL"), permits
indemnification of directors, officers, agents and controlling persons of a corporation under certain conditions and subject to certain limitations. Section 145 empowers a corporation to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director, officer or agent of the corporation
or another enterprise if serving at the request of the corporation. Depending on the character of the proceeding, a corporation may indemnify against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually
and reasonably incurred in connection with such action, suit or proceeding if the person indemnified acted in good faith and in a manner he or she reasonably believed to be in or not opposed to, the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. In the case of an action by or in the right of the corporation, no indemnification may be made with respect to any claim, issue or
matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine that despite the adjudication of
liability such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper. Section 145 further provides that to the extent a present or former director or officer of a corporation has been
successful in the defense of any action, suit
II-1
Table of Contents
or proceeding referred to above or in the defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection therewith. The foregoing is only a summary of the described sections of the Delaware General Corporation Law and is qualified in its entirety by reference to such sections.
The Registrant's Certificate of Incorporation eliminates the personal liability of directors to the fullest extent permitted by the
Delaware General Corporation Law and, together with the Registrant's Bylaws, provides that the Registrant shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it may be amended or supplemented, any person who
was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person, or a person for whom such person is the
legal representative, is or was a director or officer of the Registrant or, while a director or officer of the Registrant, is or was serving at the request of the Registrant as a director, officer, employee or agent of another corporation or of a
partnership, joint venture, trust, enterprise or nonprofit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys' fees) reasonably incurred by such person.
The Registrant has also obtained liability insurance for its officers and directors.
We have an insurance policy that insures our
directors and officers, within the limits and subject to the limitations of the policy, against certain expenses in connection with the defense of actions, suits or proceedings, and certain liabilities that might be imposed as a result of such
actions, suits or proceedings, to which they are parties by reason of being or having been directors or officers.
Insofar as
indemnification for liabilities arising under the Securities Act may be permitted to the Company's directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion
of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification
by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Item 9. Undertakings.
A. The undersigned Registrant hereby undertakes:
1. To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i) To include any prospectus required by section 10(a)(3) of the Securities Act;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective
Registration Statement.
(iii) To include any material information with respect to the plan of distribution not previously disclosed in the
Registration Statement or any material change to such information in the Registration Statement;
Provided, however,
that paragraphs
(A)(1)(i) and (A)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to section 13 or
section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.
2. That, for the purpose of
determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.
3. To remove from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.
B. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering thereof.
C. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
