        <div style="text-indent:20pt; margin-top:12pt; width:505pt; line-height:11pt;">We are offering &#8199;&#8199;&#8199;&#8199; shares of our common stock. We are also offering to certain purchasers whose purchase of shares of common stock in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if any such purchaser so chooses, pre-funded warrants, in lieu of shares of common stock that would otherwise result in such purchaser&#8217;s beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. The purchase price of each pre-funded warrant will be equal to the price per share at which shares of common stock are sold to the public in this offering, minus $0.01, and the exercise price of each pre-funded warrant will be $0.01 per share. This offering also relates to the shares of common stock issuable upon exercise of any pre-funded warrants sold in this offering. The pre-funded warrants will be exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. For each pre-funded warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. Our common stock is listed on the NYSE American under the symbol &#8220;APHB.&#8221; On August&#160;20, 2018, the last reported sale price of our common stock on the NYSE American was $1.16 per share. The public offering price per share and any pre-funded warrant will be determined between us and the underwriter at the time of pricing, and may be at a discount to the current market price. There is no established public trading market for the pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the pre-funded warrants on any national securities exchange or other nationally recognized trading system. </div>

          <div style="margin-top:12pt; text-align:center; width:456pt; line-height:11pt;font-weight:bold;">Overview </div>
          <div style="margin-top:12pt; width:456pt; line-height:11pt;font-weight:bold;">Our Company </div>
          <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We are a biotechnology company pioneering the development of precisely targeted bacteriophage therapeutics for patients with serious and life-threatening antibiotic-resistant bacterial infections. Phages have a powerful and highly selective mechanism of action that enables them to bind to and kill specific bacteria. We believe that phages represent a promising means to treat bacterial infections, especially those that have developed resistance to current therapies, including the so-called multi-drug-resistant or &#8220;superbug&#8221; strains of bacteria. </div>
          <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Our goal is to be the leading developer of bacteriophage therapeutics. We are combining our expertise in the manufacture of drug-quality bacteriophages and our proprietary approach and expertise in identifying, characterizing and developing naturally occurring bacteriophages to develop state-of-the-art therapeutics. We are developing bacteriophage products to combat multi- or pan-drug-resistant bacterial pathogens, leveraging advances in sequencing and molecular biology. We have developed certain bacteriophage combinations that we believe maximize efficacy and minimize development of resistance. We currently have two product candidates in clinical development, AB-SA01 and AB-PA01 for the treatment of <font style="font-style:italic;">Staphylococcus aureus,</font> or <font style="font-style:italic;">S. aureus,</font> infections, including methicillin-resistant <font style="font-style:italic;">S. aureus</font>, or MRSA, and <font style="font-style:italic;">Pseudomonas aeruginosa</font>, or <font style="font-style:italic;">P. aeruginosa,</font> infections, respectively. We intend to develop both product candidates for the treatment of serious or life-threatening, multi-drug resistant infections. </div>
          <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We believe our bacteriophage technology may have unique application in the area of targeted medicine, and in May&#160;2017, we initiated a new strategic emphasis on targeted therapies for serious or life-threatening antibiotic-resistant infections. In particular, we believe our bacteriophage technology can be used to develop precisely targeted therapies for patients who suffer from serious or life-threatening antibiotic-resistant bacterial infections and who have limited or no other satisfactory treatment options. Moreover, we believe our ability to target bacteriophage therapies for antibiotic-resistant infections, combined with the ability of bacteriophage to disrupt biofilm and having the potential to re-sensitize drug-resistant populations to antibiotics, represents what could be a powerful tool against the growing global challenge of antibiotic-resistant infections. </div>
          <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Under existing single-patient expanded access guidelines (also referred to as &#8220;compassionate use&#8221;), established by the regulatory agencies, we have provided targeted phage therapies to patients suffering from severe antibiotic-resistant infections who have failed prior antibiotic therapies. We believe this strategic approach not only provides potential benefit to patients who have few or no other acceptable therapeutic options, but also generates the clinical and microbiological data from these cases that we expect to support the potential validation of the clinical utility of phage therapy, identify the most promising indications for&#160;further clinical development of our AB-SA01 and AB-PA01 product candidates for <font style="font-style:italic;">S. aureus</font> and <font style="font-style:italic;">P.&#160;aeruginosa</font>, define optimal treatment regimens, and inform our discussions with the U.S. Food and Drug Administration, or FDA, and other regulatory agencies in 2018 or later on defining a potential path to market approval. We are initially making targeted phage therapies available under the appropriate regulatory expanded access guidelines in the United States and in Australia, where we collaborate with </div>

We believe that the United States and Australia have favorable regulatory frameworks and clinical expertise with respect to treating patients under single-patient expanded access guidelines. </div>
          <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We conducted meetings with the FDA in February of 2017 and August of 2018. In the most recent meeting with the FDA that was focused on our AB-SA01 product candidate targeting <font style="font-style:italic;">S. aureus</font>, we shared the clinical and microbiological results for patients treated with AB-SA01 under our single-patient expanded access program in 2017 and 2018 and the proposed design of randomized controlled clinical trials that we have developed based on input from key infectious disease physician opinion leaders, in order to establish a Phase&#160;2 development plan for multiple indications. Based on the discussions and FDA feedback in the August&#160;2018 meeting, we intend to proceed with our clinical development plans and conduct one or more randomized controlled clinical trials to evaluate the safety and efficacy of AB-SA01. In addition, during the previous meeting with the FDA in February&#160;2017, we received feedback on our previously submitted detailed development proposal to commence a Phase&#160;2 trial with AB-SA01 for the treatment of antibiotic-resistant <font style="font-style:italic;">S. aureus</font> infections in patients with chronic rhinosinusitis. In the official minutes from that meeting, the FDA acknowledged that phage therapy is an exciting approach for treatment of multi-drug- resistant organisms and expressed a commitment to addressing the unique regulatory challenges that might arise during product development. </div>

          <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We qualify as an &#8220;emerging growth company&#8221; as defined in the Jumpstart Our Business Startups Act, or JOBS Act, enacted in April&#160;2012. An &#8220;emerging growth company&#8221; may take advantage of reduced reporting requirements that are otherwise applicable to public companies. These provisions include, but are not limited to: </div>

However, if certain events occur prior to the end of such five-year period, including if we become a &#8220;large accelerated filer,&#8221; our annual gross revenues exceed approximately $1.0&#160;billion or we issue more than $1.0&#160;billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period. </div>

Each pre-funded warrant will be exercisable for one share of our common stock.

        <div style="text-align:center; width:456pt; line-height:11pt;font-weight:bold;">RISK FACTORS </div>
        <div style="text-indent:20pt; margin-top:5.81pt; width:456pt; line-height:12pt;font-style:italic;">Investing in our securities involves a high degree of risk. You should consider carefully the risks described below, together with all of the other information included or incorporated by reference in this prospectus, including the risks and uncertainties discussed under &#8220;Risk Factors&#8221; in our Quarterly Report on Form 10-Q for the quarter ended June&#160;30, 2018, before deciding whether to purchase our securities in this offering. All of these risk factors are incorporated herein in their entirety. The risks described below and incorporated by reference are material risks currently known, expected or reasonably foreseeable by us. However, the risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, operating results, prospects or financial condition. If any of these risks actually materialize, our business, prospects, financial condition, and results of operations could be seriously harmed. This could cause the trading price of our common stock and the value of the warrants to decline, resulting in a loss of all or part of your investment. </div>
        <div style="margin-top:11.61pt; width:456pt; line-height:11pt;font-weight:bold;">Risks Related to this Offering </div>
        <div style="margin-top:10.61pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">You will experience immediate and substantial dilution if you purchase securities in this offering. </div>
        <div style="text-indent:20pt; margin-top:5.81pt; width:456pt; line-height:12pt;">As of June&#160;30, 2018, our net tangible book value was approximately $3.4&#160;million, or $0.21 per share. Since the price per share of our common stock being offered in this offering is substantially higher than the net tangible book value per share of our common stock, you will suffer substantial dilution with respect to the net tangible book value of the common stock you purchase in this offering. Based on the assumed public offering price of&#8201; $&#8199;&#8199;&#8199;&#8199; per share of common stock being sold in this offering (the last reported sale price of our common stock on the NYSE American on &#8199;&#8199;&#8199;&#8199;&#8199;&#8199;&#8199;&#8199; &#8199;&#8199;, 2018), and our net tangible book value per share as of June&#160;30, 2018, if you purchase shares of common stock in this offering, you will suffer immediate and substantial dilution of&#8201; $&#8199;&#8199;&#8199;&#8199; per share with respect to the net tangible book value of the common stock. See the section entitled &#8220;Dilution&#8221; for a more detailed discussion of the dilution you will incur if you purchase common stock in this offering. The discussion above assumes no sale of pre-funded warrants, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis until such warrants are exercised. </div>
        <div style="margin-top:11.61pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">There is no public market for the pre-funded warrants being offered in this offering. </div>
        <div style="text-indent:20pt; margin-top:5.81pt; width:456pt; line-height:12pt;">There is no established public trading market for the pre-funded warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the pre-funded warrants on any securities exchange or nationally recognized trading system, including the NYSE American. Without an active market, the liquidity of the pre-funded warrants will be limited. </div>
        <div style="margin-top:11.62pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively. </div>
        <div style="text-indent:20pt; margin-top:5.8pt; width:456pt; line-height:12pt;">Our management will have broad discretion in the application of the net proceeds from this offering, including for any of the purposes described in the section entitled &#8220;Use of Proceeds,&#8221; and you will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our management may not apply the net proceeds from this offering in ways that ultimately increase the value of your investment. The failure by our management to apply these funds effectively could harm our business. Pending their use, we may invest the net proceeds from this offering in short-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline. </div>
        <div style="margin-top:11.62pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">There may be future sales of our securities or other dilution of our equity, which may adversely affect the market price of our common stock. </div>
        <div style="text-indent:20pt; margin-top:5.8pt; width:456pt; line-height:12pt;">We are generally not restricted from issuing additional common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. The market price of our common stock could decline as a result of sales of common stock or securities that are convertible into or exchangeable for, or that represent the right to receive, common stock after this offering or the perception that such sales could occur. </div>

      <div style="margin-top:46pt;margin-left:70pt;width:456pt;">
        <div style="width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">Holders of pre-funded warrants purchased in this offering will have no rights as common stockholders until such holders exercise their pre-funded warrants and acquire our common stock. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Until holders of pre-funded warrants acquire shares of our common stock upon exercise of the pre-funded warrants, holders of pre-funded warrants will have no rights with respect to the shares of our common stock underlying such pre-funded warrants. Upon exercise of the pre-funded warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">Even if this offering is successful, we will need to raise additional capital in the future to continue operations, which may not be available on acceptable terms, or at all. Failure to obtain this necessary capital when needed may force us to delay, limit or terminate our product development efforts or other operations. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We have had recurring losses from operations, negative operating cash flow and an accumulated deficit. We do not generate any cash from operations and must raise additional funds in order to continue operating our business. We expect to continue to fund our operations primarily through equity and debt financings in the future. If additional capital is not available to us when needed or on acceptable terms, we may not be able to continue to operate our business pursuant to our business plan or we may have to discontinue our operations entirely. As of June&#160;30, 2018, we had cash and cash equivalents of&#8201; $5.8&#160;million. We estimate that we will receive net proceeds of approximately $&#8199;&#8199;&#8199;&#8199; million from the sale of the securities offered by us in this offering, based on the assumed public offering price of&#8201; $&#8199;&#8199;&#8199;&#8199; per share (the last reported sale price of our common stock on the NYSE American on &#8199;&#8199;&#8199;&#8199;&#8199;&#8199;&#8199;&#8199; &#8199;&#8199;, 2018) and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering. We currently anticipate that our existing resources, together with the expected net proceeds from this offering, will be sufficient to fund our planned operations until &#8199;&#8199;&#8199;&#8199;. In the event of a decrease in the net proceeds to us from this offering as a result of a decrease in the assumed public offering price or the number of shares offered by us, we may need to raise additional capital sooner than we anticipate. In addition, we cannot provide assurances that our plans will not change or that changed circumstances will not result in the depletion of our capital resources more rapidly than we currently anticipate. </div>

Our ability to raise additional funds will depend, in part, on the success of our product development activities, including our targeted phage therapies strategy and any clinical trials we initiate, regulatory events, our ability to identify and enter into in-licensing or other strategic arrangements, and other events or conditions that may affect our value or prospects, as well as factors related to financial, economic and market conditions, many of which are beyond our control. There can be no assurances that sufficient funds will be available to us when required or on acceptable terms, if at all. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">If we are unable to secure additional funds when needed or on acceptable terms, we may be required to defer, reduce or eliminate significant planned expenditures, restructure, curtail or eliminate some or all of our development programs or other operations, dispose of technology or assets, pursue an acquisition of our company by a third party at a price that may result in a loss on investment for our stockholders, enter into arrangements that may require us to relinquish rights to certain of our product candidates, technologies or potential markets, file for bankruptcy or cease operations altogether. Any of these events could have a material adverse effect on our business, financial condition and results of operations. Moreover, if we are unable to obtain additional funds on a timely basis, there will be substantial doubt about our ability to continue as a going concern and increased risk of insolvency and up to a total loss of investment by our stockholders. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">We are reviewing strategic alternatives and there can be no assurance that we will be successful in identifying or completing any strategic transaction, that any such strategic transaction will result in additional value for our stockholders or that the process will not have an adverse impact on our business. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">In December&#160;2017, we announced that we engaged Ladenburg Thalmann &amp; Co. Inc. to conduct a review of strategic alternatives in an effort to maximize stockholder value. We have not set a timetable for completion of this exploratory process and cannot provide any assurances that the process will result in the consummation of a strategic transaction of any kind, or that we will not abandon the process. We do not intend to discuss or disclose further developments during this process unless and until our board of directors has approved a specific action or we otherwise determine that further disclosure is appropriate. The process of reviewing strategic alternatives may be time consuming and disruptive to our business operations and, if we are unable to effectively manage the process, our business, financial condition and results of operations could be adversely affected. We could incur substantial expenses associated with identifying, evaluating and negotiating potential strategic alternatives. There can be no assurance that any potential transaction or other strategic alternative, if consummated, will provide greater value to our stockholders than that reflected in the current price of our common stock. Until the review process is concluded, perceived uncertainties related to our future may result in the loss of potential business opportunities and volatility in the market price of our common stock and may make it more difficult for us to attract and retain qualified personnel and business partners. </div>

        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We estimate that we will receive net proceeds of approximately $&#8199;&#8199;&#8199;&#8199; million (or approximately $&#8199;&#8199;&#8199;&#8199;&#160;million if the underwriter&#8217;s over-allotment option is exercised in full) from the sale of the securities offered by us in this offering, based on the assumed public offering price of&#8201; $&#8199;&#8199;&#8199;&#8199; per share (the last reported sale price of our common stock on the NYSE American on &#8199;&#8199;&#8199;&#8199;&#8199;&#8199;&#8199;&#8199; &#8199;&#8199;, 2018), and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">A $&#8199;&#8199;&#8199;&#8199; increase (decrease) in the assumed public offering price of&#8201; $&#8199;&#8199;&#8199;&#8199; per share would increase (decrease) the expected net proceeds to us from this offering by approximately $&#8199;&#8199;&#8199;&#8199; million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Similarly, a one million share increase (decrease) in the number of shares offered by us, as set forth on the cover page of this prospectus, would increase (decrease) the net proceeds to us by approximately $&#8199;&#8199;&#8199;&#8199;&#160;million, assuming the assumed public offering price of&#8201; $&#8199;&#8199;&#8199;&#8199; per share remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We currently intend to use the net proceeds from this offering for general corporate purposes, including conducting one or more randomized controlled clinical trials to evaluate the safety and efficacy of AB-SA01 for the treatment of <font style="font-style:italic;">S. aureus</font> infections in multiple indications along with associated manufacturing expenses, research and development expenses, and general and administrative expense.

        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We may also use a portion of the net proceeds from this offering to in-license, acquire, or invest in complementary businesses, technologies, products or assets. However, we have no current plans, commitments or obligations to do so. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Our expected use of net proceeds from this offering represents our current intentions based upon our present plans and business condition. As of the date of this prospectus, we cannot currently allocate specific&#160;percentages of the net proceeds that we may use for the purposes specified above, and we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the completion of this offering, or the amounts that we will actually spend on the uses set forth above. The amounts and timing of our actual use of the net proceeds will vary depending on numerous factors, including our ability to obtain additional financing, the progress, cost and results of our preclinical and clinical development programs and single-patient expanded access program, and whether we are able to enter into future licensing or collaboration arrangements. We may find it necessary or advisable to use the net proceeds for other purposes, and our management will have broad discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the net proceeds from this offering. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Pending the use of the net proceeds from this offering, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.<br ></div>

        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">The following table is based upon information supplied by officers, directors and principal stockholders and/or a review of Schedules 13D and 13G, if any, and other documents filed with the SEC. We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of our common stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercisable on or before August&#160;29, 2018, which is 60&#160;days after June&#160;30, 2018. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the&#160;percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the&#160;percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws. </div>

        <div style="text-align:center; width:456pt; line-height:11pt;font-weight:bold;">DESCRIPTION OF CAPITAL STOCK </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">The following description of our capital stock, certain provisions of our articles of incorporation and bylaws, and certain provisions of Washington law are summaries. The following description is not complete and is subject to and qualified in its entirety by our articles of incorporation and bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part, and by the relevant provisions of the Washington Business Corporation Act. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">As of the date of this prospectus, our articles of incorporation authorize us to issue 67,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of preferred stock, par value $0.01 per&#160;share. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-weight:bold;">Common Stock </div>
        <div style="margin-left:20pt; margin-top:6pt; width:436pt; line-height:12pt;">The holders of our common stock are entitled to the following rights: </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">Voting </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Our common stock is entitled to one vote for each share held on all matters submitted to a vote of the stockholders, including the election of directors, and does not have cumulative voting rights. Accordingly, the holders of a majority of the shares of our common stock entitled to vote in any election of directors can elect all of the directors standing for election. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">Dividends </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Subject to preferences that may be applicable to any then-outstanding preferred stock, the holders of common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">Liquidation </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">In the event of our liquidation, dissolution or winding-up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities, subject to the satisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-style:italic;font-weight:bold;">Rights and Preferences </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Holders of our common stock have no preemptive, conversion or subscription rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that are outstanding or that we may designate and issue in the future. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-weight:bold;">Preferred Stock </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Our board of directors has the authority, without further action by the stockholders, to issue 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of the common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in our control that may otherwise benefit holders of our common stock and may adversely affect the market price of the common stock and the voting and other rights of the holders of common stock. </div>

        <div style="text-indent:20pt; width:456pt; line-height:12pt;">There currently are no provisions under our amended and restated articles of incorporation or under any other contractual obligations whereby we are authorized or required to issue or sell shares of preferred stock and we have no present plans to issue any shares of preferred stock. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-weight:bold;">Anti-Takeover Effects of Provisions of Our Articles of Incorporation, Our Bylaws and Washington Law </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Provisions in our articles of incorporation, our bylaws and under Washington law may delay or prevent an acquisition of us or a change in our management, including transactions in which stockholders might otherwise receive a premium for their shares or transactions that our stockholders might otherwise deem to be in their best interests. These provisions include a classified board of directors and a requirement for the vote of stockholders holding at least two-thirds of all shares of our issued and outstanding capital stock to approve certain changes to our articles of incorporation or certain business combinations. These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. Additionally, because we are incorporated in Washington, we are governed by the provisions of Chapter 23B.19 of the Washington Business Corporation Act, which, among other things, prohibits a target corporation, with certain exceptions, from engaging in certain &#8220;significant business transactions&#8221; for a period of five&#160;years after the share acquisition by an &#8220;acquiring person&#8221;, unless (a)&#160;the significant business transaction is approved by a majority of the members of the target corporation&#8217;s board of directors prior to the time of acquisition or (b)&#160;the significant business transaction was approved by both the majority of the members of the target corporation&#8217;s board of directors and approved at a stockholder meeting by at least two-thirds of the outstanding voting shares (excluding the acquiring person&#8217;s shares or shares over which the acquiring person has voting control) at or subsequent to the acquiring person&#8217;s share acquisition. An &#8220;acquiring person&#8221; is defined as a person or group of persons which beneficially owns 10% or more of the voting securities of the target corporation. Such significant business transactions may include, among other things: </div>

        <div style=" float:left; margin-top:9.97pt; margin-bottom:0pt; line-height:12pt; text-align:left; width:415.5pt;">any merger or consolidation with, disposition of assets to, or issuance or redemption of stock to or from, the acquiring person; </div>

        <div style=" float:left; margin-top:9.98pt; margin-bottom:0pt; line-height:12pt; text-align:left; width:415.5pt;">any termination of 5% or more of the employees of the target corporation as a result of the acquiring person&#8217;s acquisition of 10% or more of the shares; or </div>

        <div style=" float:left; margin-top:9.98pt; margin-bottom:0pt; line-height:12pt; text-align:left; width:415.5pt;">allowing the acquiring person to receive any disproportionate benefit as a stockholder. </div>

        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">After the five-year period, a significant business transaction may take place as long as it complies with certain fair price provisions of the statute or is approved by a majority of the votes entitled to be counted within each voting group entitled to vote separately on the transaction (excluding the acquiring person&#8217;s shares or shares over which the acquiring person has voting control) at an annual or special meeting of stockholders. </div>

        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">We are offering &#8199;&#8199;&#8199;&#8199; shares of our common stock or pre-funded warrants to purchase shares of our common stock. The shares of common stock or pre-funded warrants will be issued separately. We are also registering the shares of common stock issuable from time to time upon exercise of the pre-funded warrants offered hereby. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-weight:bold;">Common Stock </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">The material terms and provisions of our common stock and each other class of our securities which qualifies or limits our common stock are described under the caption &#8220;Description of Capital Stock&#8221; in this prospectus. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-weight:bold;">Pre-Funded Warrants </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;font-style:italic;">The following summary of certain terms and provisions of pre-funded warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the pre-funded warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of pre-funded warrant for a complete description of the terms and conditions of the pre-funded warrants. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">
          <font style="font-style:italic;">Duration and Exercise Price.</font>&nbsp;&nbsp;&nbsp;Each pre-funded warrant offered hereby will have an initial exercise price per share equal to $0.01. The pre-funded warrants will be immediately exercisable and may be exercised at any time until the pre-funded warrants are exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">
          <font style="font-style:italic;">Exercisability.</font> &nbsp;&nbsp;&nbsp;The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the pre-funded warrant to the extent that the holder would own more than 4.99% of the outstanding common stock immediately after exercise, except that upon at least 61&#160;days&#8217; prior <font style="font-style:italic;">notice</font> from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder&#8217;s pre-funded warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such&#160;percentage ownership is determined in accordance with the terms of the pre-funded warrants. Purchasers of pre-funded warrants in this offering may also elect prior to the issuance of the pre-funded warrants to have the initial exercise limitation set at 9.99% of our outstanding common stock. No fractional shares of common stock will be issued in connection with the exercise of a pre-funded warrant. In lieu of fractional shares, we will either pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price or round up to the next whole share. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">
          <font style="font-style:italic;">Cashless Exercise.</font> &nbsp;&nbsp;&nbsp; If, at the time a holder exercises its pre-funded warrants, a registration statement registering the issuance of the shares of common stock underlying the pre-funded warrants under the Securities Act is not then effective or available, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the pre-funded warrants. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">
          <font style="font-style:italic;">Transferability.</font> &nbsp;&nbsp;&nbsp;Subject to applicable laws, a pre-funded warrant may be transferred at the option of the holder upon surrender of the pre-funded warrant to us together with the appropriate instruments of transfer. </div>

          <font style="font-style:italic;">Exchange Listing.</font> &nbsp;&nbsp;&nbsp;There is no trading market available for the pre-funded warrants on any securities exchange or nationally recognized trading system.

        <div style=" float:left; margin-top:9.98pt; margin-bottom:0pt; line-height:12pt; text-align:left; width:415.5pt;">Syndicate covering transactions involve purchases of securities in the open market after the distribution has been completed in order to cover syndicate short positions. Such a naked short position would be closed out by buying securities in the open market. A naked short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering. </div>
        <div style="clear:both; padding:0pt; margin:0pt;font-size:0pt;line-height:0pt;">&#8203;</div>
        <div style=" float:left; margin-left:20pt; line-height:12pt; margin-top:9.98pt; margin-bottom:0pt; text-align:left; width:20pt;white-space:nowrap;">&#8226;<br ></div>
        <div style=" float:left; margin-top:9.98pt; margin-bottom:0pt; line-height:12pt; text-align:left; width:415.5pt;">Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specific maximum. </div>
        <div style="clear:both; padding:0pt; margin:0pt;font-size:0pt;line-height:0pt;">&#8203;</div>
        <div style=" float:left; margin-left:20pt; line-height:12pt; margin-top:9.97pt; margin-bottom:0pt; text-align:left; width:20pt;white-space:nowrap;">&#8226;<br ></div>
        <div style=" float:left; margin-top:9.97pt; margin-bottom:0pt; line-height:12pt; text-align:left; width:415.5pt;">Penalty bids permit the underwriter to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions. </div>
        <div style="clear:both; padding:0pt; margin:0pt;font-size:0pt;line-height:0pt;">&#8203;</div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">These syndicate covering transactions, stabilizing transactions and penalty bids may have the effect of raising or maintaining the market prices of our securities or preventing or retarding a decline in the market prices of our securities. As a result, the price of our shares of common stock may be higher than the price that might otherwise exist in the open market. Neither we nor the underwriter make any representation or prediction as to the effect that the transactions described above may have on the price of our shares of common stock. These transactions may be effected on the NYSE American, in the over-the-counter market or on any other trading market and, if commenced, may be discontinued at any time. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">In connection with this offering, the underwriter also may engage in passive market making transactions in our shares of common stock in accordance with Regulation&#160;M during a period before the commencement of offers or sales of our shares of common stock in this offering and extending through the completion of the distribution. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for that security. However, if all independent bids are lowered below the passive market maker&#8217;s bid that bid must then be lowered when specific purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time. </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of our securities. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that any transactions, once commenced, will not be discontinued without notice. </div>
        <div style="margin-top:12pt; width:456pt; line-height:11pt;font-weight:bold;">Other Relationships </div>
        <div style="text-indent:20pt; margin-top:6pt; width:456pt; line-height:12pt;">From time to time, certain of the underwriter and their affiliates have provided, and may provide in the future, various advisory, investment and commercial banking and other services to us in the ordinary course of business, for which they have received and may continue to receive customary fees and commissions. H.C. Wainwright &amp; Co., LLC served as our sole book-running manager in connection with our underwritten public offering we consummated on May&#160;10, 2017, for which it received compensation. H.C.&#160;Wainwright &amp; Co., LLC served as our exclusive placement agent in connection with our registered public offerings we consummated in January&#160;2018 and March&#160;2018, for which it received compensation.<br ></div>

Sections&#160;23B.08.510 and 23B.08.570 of the Washington Business Corporation Act authorize Washington corporations to indemnify directors and officers under certain circumstances against expenses (including legal expenses) and liabilities incurred in legal proceedings in which they are involved by reason of being a director or officer, as applicable. Section&#160;23B.08.560 of the Washington Business Corporation Act authorizes a corporation, if authorized by its articles of incorporation or by a provision in the corporation&#8217;s bylaws approved by its stockholders, to indemnify or agree to indemnify a director made a party to a proceeding, or obligate itself to advance or reimburse expenses incurred in a proceeding, without regard to the limitations imposed by Sections&#160;23B.08.510 through 23B.08.550; provided that no such indemnity shall indemnify any director from or on account of&#8201; (a)&#160;acts or omissions of the director finally adjudged to be intentional misconduct or a knowing violation of law, (b)&#160;conduct of the director finally adjudged to be in violation of Section&#160;23B.08.310 of the Washington Business Corporation Act (which section relates to unlawful distributions) or (c)&#160;any transaction with respect to which it was finally adjudged that such director personally received a benefit in money, property or services to which the director was not legally entitled. </div>

Section&#160;10 of the Registrant&#8217;s amended and restated bylaws requires the Registrant to indemnify every present or former director or officer against expenses, liabilities and losses incurred in connection with serving as a director or officer, as applicable, and to advance expenses of such director or officer incurred in defending any proceeding covered by the indemnity. </div>

The Registrant has also entered into indemnification agreements with its executive officers and directors that provide for the indemnification of directors and executive officers to the fullest extent permitted by the Washington Business Corporation Act against expenses reasonably incurred by such persons in any threatened, pending or completed action, suit, investigation or proceeding in connection with their service as (i)&#160;a director or officer or (ii) a director, officer, employee or agent of another </div>

TABLE OF CONTENTS
The information in this preliminary prospectus is not complete and may be changed. We may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective. This prospectus is not an offer to sell these securities and we are not soliciting an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.
PRELIMINARY PROSPECTUS
SUBJECT TO COMPLETION, DATED AUGUST 21, 2018
Shares of Common Stock
Pre-Funded Warrants to Purchase Shares of Common Stock
We are offering      shares of our common stock. We are also offering to certain purchasers whose purchase of shares of common stock in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if any such purchaser so chooses, pre-funded warrants, in lieu of shares of common stock that would otherwise result in such purchaser's beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. The purchase price of each pre-funded warrant will be equal to the price per share at which shares of common stock are sold to the public in this offering, minus $0.01, and the exercise price of each pre-funded warrant will be $0.01 per share. This offering also relates to the shares of common stock issuable upon exercise of any pre-funded warrants sold in this offering. The pre-funded warrants will be exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. For each pre-funded warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. Our common stock is listed on the NYSE American under the symbol "APHB." On August 20, 2018, the last reported sale price of our common stock on the NYSE American was $1.16 per share. The public offering price per share and any pre-funded warrant will be determined between us and the underwriter at the time of pricing, and may be at a discount to the current market price. There is no established public trading market for the pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply for a listing of the pre-funded warrants on any national securities exchange or other nationally recognized trading system.
We are an "emerging growth company" as that term is used in the Jumpstart Our Business Startups Act of 2012 and, as such, we have elected to comply with certain reduced public company reporting requirements for this prospectus and future filings.

In addition, we have agreed to reimburse the underwriter for certain expenses. See "Underwriting" for additional information.
​
The offering is being underwritten on a firm commitment basis. We have granted the underwriter an option for a period of 30 days from the date of this prospectus to purchase up to an additional      shares of our common stock at the public offering price, less the underwriting discounts and commissions, to cover over-allotments, if any. If the underwriter exercises this option in full, the total underwriting discounts and commissions payable by us will be $    , and the total proceeds to us, before expenses, will be $    .
Investing in our securities involves a high degree of risk. See the section entitled "Risk Factors" beginning on page
7
of this prospectus and in the documents incorporated by reference into this prospectus for a discussion of risks that should be considered in connection with an investment in our securities.
Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.
The underwriter expects to deliver the shares of common stock and any pre-funded warrants to purchasers on or about            , 2018.

Overview
Our Company
We are a biotechnology company pioneering the development of precisely targeted bacteriophage therapeutics for patients with serious and life-threatening antibiotic-resistant bacterial infections. Phages have a powerful and highly selective mechanism of action that enables them to bind to and kill specific bacteria. We believe that phages represent a promising means to treat bacterial infections, especially those that have developed resistance to current therapies, including the so-called multi-drug-resistant or "superbug" strains of bacteria.
Our goal is to be the leading developer of bacteriophage therapeutics. We are combining our expertise in the manufacture of drug-quality bacteriophages and our proprietary approach and expertise in identifying, characterizing and developing naturally occurring bacteriophages to develop state-of-the-art therapeutics. We are developing bacteriophage products to combat multi- or pan-drug-resistant bacterial pathogens, leveraging advances in sequencing and molecular biology. We have developed certain bacteriophage combinations that we believe maximize efficacy and minimize development of resistance. We currently have two product candidates in clinical development, AB-SA01 and AB-PA01 for the treatment of
Staphylococcus aureus,
or
S. aureus,
infections, including methicillin-resistant
S. aureus
, or MRSA, and
Pseudomonas aeruginosa
, or
P. aeruginosa,
infections, respectively. We intend to develop both product candidates for the treatment of serious or life-threatening, multi-drug resistant infections.
We believe our bacteriophage technology may have unique application in the area of targeted medicine, and in May 2017, we initiated a new strategic emphasis on targeted therapies for serious or life-threatening antibiotic-resistant infections. In particular, we believe our bacteriophage technology can be used to develop precisely targeted therapies for patients who suffer from serious or life-threatening antibiotic-resistant bacterial infections and who have limited or no other satisfactory treatment options. Moreover, we believe our ability to target bacteriophage therapies for antibiotic-resistant infections, combined with the ability of bacteriophage to disrupt biofilm and having the potential to re-sensitize drug-resistant populations to antibiotics, represents what could be a powerful tool against the growing global challenge of antibiotic-resistant infections.
Under existing single-patient expanded access guidelines (also referred to as "compassionate use"), established by the regulatory agencies, we have provided targeted phage therapies to patients suffering from severe antibiotic-resistant infections who have failed prior antibiotic therapies. We believe this strategic approach not only provides potential benefit to patients who have few or no other acceptable therapeutic options, but also generates the clinical and microbiological data from these cases that we expect to support the potential validation of the clinical utility of phage therapy, identify the most promising indications for further clinical development of our AB-SA01 and AB-PA01 product candidates for
S. aureus
and
P. aeruginosa
, define optimal treatment regimens, and inform our discussions with the U.S. Food and Drug Administration, or FDA, and other regulatory agencies in 2018 or later on defining a potential path to market approval. We are initially making targeted phage therapies available under the appropriate regulatory expanded access guidelines in the United States and in Australia, where we collaborate with
1
TABLE OF CONTENTS
select leading hospitals and key infectious disease physician opinion leaders to identify eligible patients. We believe that the United States and Australia have favorable regulatory frameworks and clinical expertise with respect to treating patients under single-patient expanded access guidelines.
We conducted meetings with the FDA in February of 2017 and August of 2018. In the most recent meeting with the FDA that was focused on our AB-SA01 product candidate targeting
S. aureus
, we shared the clinical and microbiological results for patients treated with AB-SA01 under our single-patient expanded access program in 2017 and 2018 and the proposed design of randomized controlled clinical trials that we have developed based on input from key infectious disease physician opinion leaders, in order to establish a Phase 2 development plan for multiple indications. Based on the discussions and FDA feedback in the August 2018 meeting, we intend to proceed with our clinical development plans and conduct one or more randomized controlled clinical trials to evaluate the safety and efficacy of AB-SA01. In addition, during the previous meeting with the FDA in February 2017, we received feedback on our previously submitted detailed development proposal to commence a Phase 2 trial with AB-SA01 for the treatment of antibiotic-resistant
S. aureus
infections in patients with chronic rhinosinusitis. In the official minutes from that meeting, the FDA acknowledged that phage therapy is an exciting approach for treatment of multi-drug- resistant organisms and expressed a commitment to addressing the unique regulatory challenges that might arise during product development.
Risks Associated with Our Business and this Offering
Our business and our ability to implement our business strategy are subject to numerous risks, as more fully described in the section of this prospectus entitled "Risk Factors" and under similarly titled headings of the documents incorporated herein by reference. You should read these risks before you invest in our securities. We may be unable, for many reasons, including those that are beyond our control, to implement our business strategy. In particular, risks associated with our business include:
•
There is substantial doubt about our ability to continue as a going concern, which may affect our ability to obtain future financing and may require us to curtail our operations. We will need to raise additional capital to support our operations.
​
•
We have incurred losses since our inception and anticipate that we will continue to incur significant losses for the foreseeable future, and our future profitability is uncertain.
​
•
Our product candidates must undergo rigorous clinical testing, such clinical testing may fail to demonstrate safety and efficacy and any of our product candidates could cause undesirable side effects, which would substantially delay or prevent regulatory approval or commercialization.
​
•
Our single-patient expanded access strategy may not be successful, which in turn could adversely affect our business.
​
•
We are dependent on patents and proprietary technology. If we fail to adequately protect this intellectual property or if we otherwise do not have exclusivity for the marketing of our products, our ability to commercialize products could suffer.
​
•
If our competitors are able to develop and market products that are more effective, safer or more affordable than ours, or obtain marketing approval before we do, our commercial opportunities may be limited.
​
•
If you purchase our securities in this offering, you will incur immediate and substantial dilution.
​
•
We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

TABLE OF CONTENTS
In January 2011, we completed the acquisition of Biocontrol Ltd, an antimicrobial biotechnology company based in the United Kingdom, with the goal of developing their phage therapy programs using funding from the sale of our legacy gene therapy assets.
In February 2011, we changed our name to "AmpliPhi Biosciences Corporation."
In November 2012, we completed the acquisition of Special Phage Holdings Pty Ltd, a company based in Australia, which we refer to as SPH, with the goal of combining SPH's research on addressing the rapidly escalating problem of antibiotic resistance through the development of a series of bacteriophage-based treatments into our own development programs.
In August 2015, we effected a 1-for-50 reverse split of our common stock, and in April 2017, we effected a 1-for-10 reverse split of our common stock. The share and per share information described in this prospectus that occurred prior to these reverse splits have been adjusted to give retrospective effect to the reverse splits.

Implications of Being an Emerging Growth Company and a Smaller Reporting Company
We qualify as an "emerging growth company" as defined in the Jumpstart Our Business Startups Act, or JOBS Act, enacted in April 2012. An "emerging growth company" may take advantage of reduced reporting requirements that are otherwise applicable to public companies. These provisions include, but are not limited to:
•
being permitted to present only two years of audited financial statements and only two years of related Management's Discussion and Analysis of Financial Condition and Results of Operations in the documents incorporated by reference into this prospectus;
​
•
not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act;
​
•
reduced disclosure obligations regarding executive compensation in our periodic reports, proxy statements and registration statements; and
​
•
exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.
​
We may use these provisions until the last day of our fiscal year following the fifth anniversary of the first sale of our equity securities pursuant to an effective registration statement under the Securities Act of 1933, as amended, or the Securities Act, after we became a reporting company under the Securities Exchange Act of 1934, as amended, or the Exchange Act, pursuant to our registration statement on Form 10 (File No. 000-23930). However, if certain events occur prior to the end of such five-year period, including if we become a "large accelerated filer," our annual gross revenues exceed approximately $1.0 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period.

TABLE OF CONTENTS
We are also a "smaller reporting company" as defined in Exchange Act and have elected to take advantage of certain of the scaled disclosures available to smaller reporting companies. We may be a smaller reporting company even after we are no longer an emerging growth company.
We have elected to take advantage of certain of the reduced disclosure obligations in the registration statement of which this prospectus is a part and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our stockholders may be different than you might receive from other public reporting companies in which you hold equity interests.
The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. We have irrevocably elected not to avail ourselves of this exemption and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

The Offering
Common stock offered by us in this offering
shares.
Pre-funded warrants offered by us in this offering
We are also offering to certain purchasers whose purchase of shares of common stock in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if such purchasers so choose, pre-funded warrants, in lieu of shares of common stock that would otherwise result in any such purchaser's beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. Each pre-funded warrant will be exercisable for one share of our common stock. The purchase price of each pre-funded warrant will equal the price per share at which the shares of common stock are being sold to the public in this offering, minus $0.01, and the exercise price of each pre-funded warrant will be $0.01 per share. The pre-funded warrants will be exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. This offering also relates to the shares of common stock issuable upon exercise of any pre-funded warrants sold in this offering. For each pre-funded warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis.
Option to purchase additional shares
The underwriter has a 30-day option to purchase up to an additional shares of our common stock at the public offering price, less underwriting discounts and commissions, to cover over-allotments, if any.
Common stock to be outstanding after this offering
shares of common stock, assuming no sale of any pre-funded warrants (or      shares of common stock if the underwriter exercises in full its option to purchase additional shares of common stock, assuming no sale of pre-funded warrants).
Use of proceeds
We intend to use the net proceeds from this offering for general corporate purposes, including conducting one or more randomized controlled clinical trials to evaluate the safety and efficacy of AB-SA01 for the treatment of
S. aureus
infections in multiple indications, along with associated manufacturing expenses, research and development expenses, and general and administrative expenses. See "Use of Proceeds."

RISK FACTORS
Investing in our securities involves a high degree of risk. You should consider carefully the risks described below, together with all of the other information included or incorporated by reference in this prospectus, including the risks and uncertainties discussed under "Risk Factors" in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2018, before deciding whether to purchase our securities in this offering. All of these risk factors are incorporated herein in their entirety. The risks described below and incorporated by reference are material risks currently known, expected or reasonably foreseeable by us. However, the risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial may also affect our business, operating results, prospects or financial condition. If any of these risks actually materialize, our business, prospects, financial condition, and results of operations could be seriously harmed. This could cause the trading price of our common stock and the value of the warrants to decline, resulting in a loss of all or part of your investment.
Risks Related to this Offering
You will experience immediate and substantial dilution if you purchase securities in this offering.
As of June 30, 2018, our net tangible book value was approximately $3.4 million, or $0.21 per share. Since the price per share of our common stock being offered in this offering is substantially higher than the net tangible book value per share of our common stock, you will suffer substantial dilution with respect to the net tangible book value of the common stock you purchase in this offering. Based on the assumed public offering price of  $     per share of common stock being sold in this offering (the last reported sale price of our common stock on the NYSE American on            , 2018), and our net tangible book value per share as of June 30, 2018, if you purchase shares of common stock in this offering, you will suffer immediate and substantial dilution of  $     per share with respect to the net tangible book value of the common stock. See the section entitled "Dilution" for a more detailed discussion of the dilution you will incur if you purchase common stock in this offering. The discussion above assumes no sale of pre-funded warrants, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis until such warrants are exercised.
There is no public market for the pre-funded warrants being offered in this offering.
There is no established public trading market for the pre-funded warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the pre-funded warrants on any securities exchange or nationally recognized trading system, including the NYSE American. Without an active market, the liquidity of the pre-funded warrants will be limited.
We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.
Our management will have broad discretion in the application of the net proceeds from this offering, including for any of the purposes described in the section entitled "Use of Proceeds," and you will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our management may not apply the net proceeds from this offering in ways that ultimately increase the value of your investment. The failure by our management to apply these funds effectively could harm our business. Pending their use, we may invest the net proceeds from this offering in short-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.
There may be future sales of our securities or other dilution of our equity, which may adversely affect the market price of our common stock.
We are generally not restricted from issuing additional common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. The market price of our common stock could decline as a result of sales of common stock or securities that are convertible into or exchangeable for, or that represent the right to receive, common stock after this offering or the perception that such sales could occur.

TABLE OF CONTENTS
Holders of pre-funded warrants purchased in this offering will have no rights as common stockholders until such holders exercise their pre-funded warrants and acquire our common stock.
Until holders of pre-funded warrants acquire shares of our common stock upon exercise of the pre-funded warrants, holders of pre-funded warrants will have no rights with respect to the shares of our common stock underlying such pre-funded warrants. Upon exercise of the pre-funded warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.
Even if this offering is successful, we will need to raise additional capital in the future to continue operations, which may not be available on acceptable terms, or at all. Failure to obtain this necessary capital when needed may force us to delay, limit or terminate our product development efforts or other operations.
We have had recurring losses from operations, negative operating cash flow and an accumulated deficit. We do not generate any cash from operations and must raise additional funds in order to continue operating our business. We expect to continue to fund our operations primarily through equity and debt financings in the future. If additional capital is not available to us when needed or on acceptable terms, we may not be able to continue to operate our business pursuant to our business plan or we may have to discontinue our operations entirely. As of June 30, 2018, we had cash and cash equivalents of  $5.8 million. We estimate that we will receive net proceeds of approximately $     million from the sale of the securities offered by us in this offering, based on the assumed public offering price of  $     per share (the last reported sale price of our common stock on the NYSE American on            , 2018) and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering. We currently anticipate that our existing resources, together with the expected net proceeds from this offering, will be sufficient to fund our planned operations until     . In the event of a decrease in the net proceeds to us from this offering as a result of a decrease in the assumed public offering price or the number of shares offered by us, we may need to raise additional capital sooner than we anticipate. In addition, we cannot provide assurances that our plans will not change or that changed circumstances will not result in the depletion of our capital resources more rapidly than we currently anticipate.
Developing drugs and conducting clinical trials is expensive. Our future funding requirements will depend on many factors, including:
•
the costs and timing of our research and development activities;
​
•
the progress and cost of our clinical trials and other research and development activities;
​
•
manufacturing costs associated with our targeted phage therapies strategy and other research and development activities;
​
•
the terms and timing of any collaborative, licensing, acquisition or other arrangements that we may establish;
​
•
whether and when we receive future Australian tax rebates, if any;
​
•
the costs and timing of seeking regulatory approvals;
​
•
the costs of filing, prosecuting, defending and enforcing any patent applications, claims, patents and other intellectual property rights; and
​
•
the costs of lawsuits involving us or our product candidates.
​
We may seek funds through arrangements with collaborators or others that may require us to relinquish rights to the products candidates that we might otherwise seek to develop or commercialize independently. We cannot be certain that we will be able to enter into any such arrangements on reasonable terms, if at all.
We may seek to raise capital through a variety of sources, including:
•
the public equity market;
​
•
private equity financings;
​
​

TABLE OF CONTENTS
•
collaborative arrangements or strategic financings;
​
•
licensing arrangements; and/or
​
•
public or private debt.
​
Any additional fundraising efforts may divert our management from their day to day activities, which may adversely affect our ability to develop and commercialize our product candidates. Our ability to raise additional funds will depend, in part, on the success of our product development activities, including our targeted phage therapies strategy and any clinical trials we initiate, regulatory events, our ability to identify and enter into in-licensing or other strategic arrangements, and other events or conditions that may affect our value or prospects, as well as factors related to financial, economic and market conditions, many of which are beyond our control. There can be no assurances that sufficient funds will be available to us when required or on acceptable terms, if at all.
If we are unable to secure additional funds when needed or on acceptable terms, we may be required to defer, reduce or eliminate significant planned expenditures, restructure, curtail or eliminate some or all of our development programs or other operations, dispose of technology or assets, pursue an acquisition of our company by a third party at a price that may result in a loss on investment for our stockholders, enter into arrangements that may require us to relinquish rights to certain of our product candidates, technologies or potential markets, file for bankruptcy or cease operations altogether. Any of these events could have a material adverse effect on our business, financial condition and results of operations. Moreover, if we are unable to obtain additional funds on a timely basis, there will be substantial doubt about our ability to continue as a going concern and increased risk of insolvency and up to a total loss of investment by our stockholders.
We are reviewing strategic alternatives and there can be no assurance that we will be successful in identifying or completing any strategic transaction, that any such strategic transaction will result in additional value for our stockholders or that the process will not have an adverse impact on our business.
In December 2017, we announced that we engaged Ladenburg Thalmann & Co. Inc. to conduct a review of strategic alternatives in an effort to maximize stockholder value. We have not set a timetable for completion of this exploratory process and cannot provide any assurances that the process will result in the consummation of a strategic transaction of any kind, or that we will not abandon the process. We do not intend to discuss or disclose further developments during this process unless and until our board of directors has approved a specific action or we otherwise determine that further disclosure is appropriate. The process of reviewing strategic alternatives may be time consuming and disruptive to our business operations and, if we are unable to effectively manage the process, our business, financial condition and results of operations could be adversely affected. We could incur substantial expenses associated with identifying, evaluating and negotiating potential strategic alternatives. There can be no assurance that any potential transaction or other strategic alternative, if consummated, will provide greater value to our stockholders than that reflected in the current price of our common stock. Until the review process is concluded, perceived uncertainties related to our future may result in the loss of potential business opportunities and volatility in the market price of our common stock and may make it more difficult for us to attract and retain qualified personnel and business partners.

We estimate that we will receive net proceeds of approximately $     million (or approximately $     million if the underwriter's over-allotment option is exercised in full) from the sale of the securities offered by us in this offering, based on the assumed public offering price of  $     per share (the last reported sale price of our common stock on the NYSE American on            , 2018), and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering.
A $     increase (decrease) in the assumed public offering price of  $     per share would increase (decrease) the expected net proceeds to us from this offering by approximately $     million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering.
Similarly, a one million share increase (decrease) in the number of shares offered by us, as set forth on the cover page of this prospectus, would increase (decrease) the net proceeds to us by approximately $     million, assuming the assumed public offering price of  $     per share remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us and excluding the proceeds, if any, from the exercise of the pre-funded warrants issued pursuant to this offering.
We currently intend to use the net proceeds from this offering for general corporate purposes, including conducting one or more randomized controlled clinical trials to evaluate the safety and efficacy of AB-SA01 for the treatment of
S. aureus
infections in multiple indications along with associated manufacturing expenses, research and development expenses, and general and administrative expense. See "Risk Factors" for a discussion of certain risks that may affect our intended use of the net proceeds from this offering.
We may also use a portion of the net proceeds from this offering to in-license, acquire, or invest in complementary businesses, technologies, products or assets. However, we have no current plans, commitments or obligations to do so.
Our expected use of net proceeds from this offering represents our current intentions based upon our present plans and business condition. As of the date of this prospectus, we cannot currently allocate specific percentages of the net proceeds that we may use for the purposes specified above, and we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the completion of this offering, or the amounts that we will actually spend on the uses set forth above. The amounts and timing of our actual use of the net proceeds will vary depending on numerous factors, including our ability to obtain additional financing, the progress, cost and results of our preclinical and clinical development programs and single-patient expanded access program, and whether we are able to enter into future licensing or collaboration arrangements. We may find it necessary or advisable to use the net proceeds for other purposes, and our management will have broad discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the net proceeds from this offering.
Pending the use of the net proceeds from this offering, we intend to invest the net proceeds in investment-grade, interest-bearing instruments.

DILUTION
Our historical net tangible book value as of June 30, 2018 was approximately $3.4 million, or $0.21 per share of common stock. Our historical net tangible book value is the amount of our total tangible assets less our liabilities. Historical net tangible book value per common share is our historical net tangible book value divided by the number of shares of common stock outstanding as of June 30, 2018.
After giving effect to the sale of       shares of our common stock at the assumed public offering price of  $     per share (the last reported sale price of our common stock on the NYSE American on            , 2018), and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering, our as adjusted net tangible book value as of June 30, 2018 would have been approximately $     million, or $     per share of common stock. This represents an immediate increase in as adjusted net tangible book value of  $     per share to our existing stockholders, and an immediate dilution of  $     per share to new investors purchasing securities in this offering at the assumed public offering price.
The following table illustrates this dilution on a per share basis:

A $     increase in the assumed public offering price of  $     per share would increase our as adjusted net tangible book value after this offering by $     million, or $     per share, and the dilution per share to investors purchasing securities in this offering would be approximately $     per share, assuming that the number of shares of common stock, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering. Similarly, a $     decrease in the assumed public offering price of $     per share would decrease our as adjusted net tangible book value after this offering by $     million, or $     per share, and the dilution per share to investors purchasing securities in this offering would be $     per share, assuming that the number of shares of common stock offered by us, as set forth on the cover page of this prospectus remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering.
We may also increase or decrease the number of shares of common stock we are offering from the assumed number of shares of common stock set forth above. An increase of       shares of common stock from the assumed number of shares of common stock set forth on the cover page of this prospectus would increase our as adjusted net tangible book value after this offering by $     million, or $     per share, and the dilution per share to investors purchasing securities in this offering would be approximately $     per share, assuming that the public offering price remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering. Similarly, a decrease of shares of common stock from the assumed number of shares of common stock set forth on the cover page of this prospectus would decrease our as adjusted net tangible book value after this offering by $     million, or $     per share, and the dilution per share to investors purchasing securities in this offering would be approximately $    , assuming that the public offering price remains the same and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of any pre-funded warrants issued pursuant to this offering. The information discussed above is illustrative only and will adjust based on the actual public offering price, the actual number of shares that we offer in this offering, and other terms of this offering

TABLE OF CONTENTS
determined at pricing. The discussion and table above assume (i) no sale of pre-funded warrants, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis and (ii) no exercise of the underwriter's over-allotment option to purchase up to an additional shares of common stock.
If the underwriter exercises in full its option to purchase up to      additional shares of common stock at the assumed public offering price of  $     per share (the last reported sale price of our common stock on the NYSE American on            , 2018), the as adjusted net tangible book value after this offering would be $     million, or $     per share, representing an increase in net tangible book value of $     per share to existing stockholders and immediate dilution in net tangible book value of  $     per share to investors purchasing our securities in this offering at the assumed public offering price.
The foregoing discussion and table does not take into account further dilution to investors in this offering that could occur upon the exercise of outstanding options and warrants, including the pre-funded warrants offered pursuant to this offering, having a per share exercise price less than the public offering price per share in this offering.
The foregoing discussion and table are based on 16,468,308 shares of common stock outstanding as of June 30, 2018, and excludes as of that date:
•
1,150,915 shares of common stock issuable upon the exercise of outstanding stock options, with exercise prices ranging from $0.73 to $135.00 and having a weighted-average exercise price of $3.09 per share;
​
•
445,376 shares of common stock reserved for future grant under the 2016 plan;
​
•
47,172 shares of common stock reserved for future issuance under the ESPP; and
​
•
8,296,995 shares of common stock issuable upon the exercise of outstanding warrants, with exercise prices ranging from $0.57 to $120.00 and having a weighted-average exercise price of $2.78 per share.
​
To the extent that options or warrants outstanding as of June 30, 2018 have been or may be exercised or other shares issued, investors purchasing securities in this offering may experience further dilution. In addition, we may seek to raise additional capital in the future through the sale of equity or convertible debt securities. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

TABLE OF CONTENTS
PRINCIPAL STOCKHOLDERS
The following table sets forth information regarding beneficial ownership of our capital stock by:
•
each person, or group of affiliated persons, known by us to beneficially own more than 5% of our common stock;
​
•
each of our directors;
​
•
each of our named executive officers; and
​
•
all of our current executive officers and directors as a group.
​
The percentage ownership information is based on 16,468,308 shares of common stock outstanding as of June 30, 2018.
The following table is based upon information supplied by officers, directors and principal stockholders and/or a review of Schedules 13D and 13G, if any, and other documents filed with the SEC. We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of our common stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercisable on or before August 29, 2018, which is 60 days after June 30, 2018. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.
Except as otherwise noted below, the address for each person or entity listed in the table is c/o AmpliPhi Biosciences Corporation, 3579 Valley Centre Drive, Suite 100, San Diego, California 92130.

DESCRIPTION OF CAPITAL STOCK
The following description of our capital stock, certain provisions of our articles of incorporation and bylaws, and certain provisions of Washington law are summaries. The following description is not complete and is subject to and qualified in its entirety by our articles of incorporation and bylaws, which are filed as exhibits to the registration statement of which this prospectus is a part, and by the relevant provisions of the Washington Business Corporation Act.
As of the date of this prospectus, our articles of incorporation authorize us to issue 67,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of preferred stock, par value $0.01 per share.
Common Stock
The holders of our common stock are entitled to the following rights:
Voting
Our common stock is entitled to one vote for each share held on all matters submitted to a vote of the stockholders, including the election of directors, and does not have cumulative voting rights. Accordingly, the holders of a majority of the shares of our common stock entitled to vote in any election of directors can elect all of the directors standing for election.
Dividends
Subject to preferences that may be applicable to any then-outstanding preferred stock, the holders of common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.
Liquidation
In the event of our liquidation, dissolution or winding-up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities, subject to the satisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock.
Rights and Preferences
Holders of our common stock have no preemptive, conversion or subscription rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that are outstanding or that we may designate and issue in the future.
Preferred Stock
Our board of directors has the authority, without further action by the stockholders, to issue 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding.
Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of the common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in our control that may otherwise benefit holders of our common stock and may adversely affect the market price of the common stock and the voting and other rights of the holders of common stock.
18
TABLE OF CONTENTS
There currently are no provisions under our amended and restated articles of incorporation or under any other contractual obligations whereby we are authorized or required to issue or sell shares of preferred stock and we have no present plans to issue any shares of preferred stock.
Anti-Takeover Effects of Provisions of Our Articles of Incorporation, Our Bylaws and Washington Law
Provisions in our articles of incorporation, our bylaws and under Washington law may delay or prevent an acquisition of us or a change in our management, including transactions in which stockholders might otherwise receive a premium for their shares or transactions that our stockholders might otherwise deem to be in their best interests. These provisions include a classified board of directors and a requirement for the vote of stockholders holding at least two-thirds of all shares of our issued and outstanding capital stock to approve certain changes to our articles of incorporation or certain business combinations. These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management. Additionally, because we are incorporated in Washington, we are governed by the provisions of Chapter 23B.19 of the Washington Business Corporation Act, which, among other things, prohibits a target corporation, with certain exceptions, from engaging in certain "significant business transactions" for a period of five years after the share acquisition by an "acquiring person", unless (a) the significant business transaction is approved by a majority of the members of the target corporation's board of directors prior to the time of acquisition or (b) the significant business transaction was approved by both the majority of the members of the target corporation's board of directors and approved at a stockholder meeting by at least two-thirds of the outstanding voting shares (excluding the acquiring person's shares or shares over which the acquiring person has voting control) at or subsequent to the acquiring person's share acquisition. An "acquiring person" is defined as a person or group of persons which beneficially owns 10% or more of the voting securities of the target corporation. Such significant business transactions may include, among other things:
•
any merger or consolidation with, disposition of assets to, or issuance or redemption of stock to or from, the acquiring person;
​
•
any termination of 5% or more of the employees of the target corporation as a result of the acquiring person's acquisition of 10% or more of the shares; or
​
•
allowing the acquiring person to receive any disproportionate benefit as a stockholder.
​
After the five-year period, a significant business transaction may take place as long as it complies with certain fair price provisions of the statute or is approved by a majority of the votes entitled to be counted within each voting group entitled to vote separately on the transaction (excluding the acquiring person's shares or shares over which the acquiring person has voting control) at an annual or special meeting of stockholders.

​
DESCRIPTION OF SECURITIES WE ARE OFFERING
We are offering      shares of our common stock or pre-funded warrants to purchase shares of our common stock. The shares of common stock or pre-funded warrants will be issued separately. We are also registering the shares of common stock issuable from time to time upon exercise of the pre-funded warrants offered hereby.
Common Stock
The material terms and provisions of our common stock and each other class of our securities which qualifies or limits our common stock are described under the caption "Description of Capital Stock" in this prospectus.
Pre-Funded Warrants
The following summary of certain terms and provisions of pre-funded warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the pre-funded warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of pre-funded warrant for a complete description of the terms and conditions of the pre-funded warrants.
Duration and Exercise Price.
Each pre-funded warrant offered hereby will have an initial exercise price per share equal to $0.01. The pre-funded warrants will be immediately exercisable and may be exercised at any time until the pre-funded warrants are exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price.
Exercisability.
The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the pre-funded warrant to the extent that the holder would own more than 4.99% of the outstanding common stock immediately after exercise, except that upon at least 61 days' prior
notice
from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder's pre-funded warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. Purchasers of pre-funded warrants in this offering may also elect prior to the issuance of the pre-funded warrants to have the initial exercise limitation set at 9.99% of our outstanding common stock. No fractional shares of common stock will be issued in connection with the exercise of a pre-funded warrant. In lieu of fractional shares, we will either pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price or round up to the next whole share.
Cashless Exercise.
If, at the time a holder exercises its pre-funded warrants, a registration statement registering the issuance of the shares of common stock underlying the pre-funded warrants under the Securities Act is not then effective or available, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the pre-funded warrants.
Transferability.

TABLE OF CONTENTS
Indemnification
Pursuant to the underwriting agreement, we have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the underwriter or such other indemnified parties may be required to make in respect of those liabilities.
Determination of Offering Price
The actual offering price of the securities we are offering will be negotiated between us and the underwriter based on the trading of our shares of common stock prior to the offering, among other things, and may be at a discount to the current market price.
Lock-Up Agreements
We have agreed not to (i) offer, pledge, issue, sell, contract to sell, purchase, contract to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock; (ii) enter into any swap or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of shares of common stock; or (iii) file any registration statement with the SEC relating to the offering of any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock, without the prior written consent of H.C. Wainwright & Co., LLC for a period of 90 days following the date of this prospectus. This consent may be given at any time without public notice. These restrictions on future issuances are subject to exceptions, including for (i) the issuance of shares of our common stock, warrants and shares of our common stock underlying the pre-funded warrants sold in this offering, (ii) the issuance of shares of our common stock upon the exercise of outstanding options or warrants or pursuant to certain other rights, (iii) the issuance of shares of our common stock or options to acquire shares of our common stock pursuant to our existing equity incentive plans and (iv) the filing of one or more registration statements on Form S-8 with respect to shares of our common stock underlying our equity incentive plans from time to time.
In addition, subject to certain limited circumstances, each of our directors and executive officers, and certain of our principal stockholders, has entered into a lock-up agreement with the underwriter. Under the lock-up agreements, the directors, executive officers and applicable stockholders may not, directly or indirectly, sell, offer to sell, contract to sell, or grant any option for the sale (including any short sale), grant any security interest in, pledge, hypothecate, hedge, establish an open "put equivalent position" (within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended, or the Exchange Act), or otherwise dispose of, or enter into any transaction which is designed to or could be expected to result in the disposition of, any shares of our common stock or securities convertible into or exchangeable for shares of our common stock, or publicly announce any intention to do any of the foregoing, without the prior written consent of H.C. Wainwright & Co., LLC, for a period of 90 days from the date of this prospectus. This consent may be given at any time without public notice.

TABLE OF CONTENTS
Price Stabilization, Short Positions and Penalty Bids
The underwriter may engage in syndicate covering transactions, stabilizing transactions and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of our shares of common stock:
•
Syndicate covering transactions involve purchases of securities in the open market after the distribution has been completed in order to cover syndicate short positions. Such a naked short position would be closed out by buying securities in the open market. A naked short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.
​
•
Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specific maximum.
​
•
Penalty bids permit the underwriter to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.
​
These syndicate covering transactions, stabilizing transactions and penalty bids may have the effect of raising or maintaining the market prices of our securities or preventing or retarding a decline in the market prices of our securities. As a result, the price of our shares of common stock may be higher than the price that might otherwise exist in the open market. Neither we nor the underwriter make any representation or prediction as to the effect that the transactions described above may have on the price of our shares of common stock. These transactions may be effected on the NYSE American, in the over-the-counter market or on any other trading market and, if commenced, may be discontinued at any time.
In connection with this offering, the underwriter also may engage in passive market making transactions in our shares of common stock in accordance with Regulation M during a period before the commencement of offers or sales of our shares of common stock in this offering and extending through the completion of the distribution. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for that security. However, if all independent bids are lowered below the passive market maker's bid that bid must then be lowered when specific purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.
Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of our securities. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that any transactions, once commenced, will not be discontinued without notice.
Other Relationships
From time to time, certain of the underwriter and their affiliates have provided, and may provide in the future, various advisory, investment and commercial banking and other services to us in the ordinary course of business, for which they have received and may continue to receive customary fees and commissions. H.C. Wainwright & Co., LLC served as our sole book-running manager in connection with our underwritten public offering we consummated on May 10, 2017, for which it received compensation. H.C. Wainwright & Co., LLC served as our exclusive placement agent in connection with our registered public offerings we consummated in January 2018 and March 2018, for which it received compensation.

Item 14.   Indemnification of Directors and Officers.
The Registrant is incorporated under the laws of the State of Washington. Sections 23B.08.510 and 23B.08.570 of the Washington Business Corporation Act authorize Washington corporations to indemnify directors and officers under certain circumstances against expenses (including legal expenses) and liabilities incurred in legal proceedings in which they are involved by reason of being a director or officer, as applicable. Section 23B.08.560 of the Washington Business Corporation Act authorizes a corporation, if authorized by its articles of incorporation or by a provision in the corporation's bylaws approved by its stockholders, to indemnify or agree to indemnify a director made a party to a proceeding, or obligate itself to advance or reimburse expenses incurred in a proceeding, without regard to the limitations imposed by Sections 23B.08.510 through 23B.08.550; provided that no such indemnity shall indemnify any director from or on account of  (a) acts or omissions of the director finally adjudged to be intentional misconduct or a knowing violation of law, (b) conduct of the director finally adjudged to be in violation of Section 23B.08.310 of the Washington Business Corporation Act (which section relates to unlawful distributions) or (c) any transaction with respect to which it was finally adjudged that such director personally received a benefit in money, property or services to which the director was not legally entitled.
Article 11 of the Registrant's articles of incorporation, provides that, to the fullest extent that the Washington Business Corporation Act permits the limitation or elimination of the liability of a director, a director shall not be liable to the Registrant or its stockholders for monetary damages for conduct as a director. Section 10 of the Registrant's amended and restated bylaws requires the Registrant to indemnify every present or former director or officer against expenses, liabilities and losses incurred in connection with serving as a director or officer, as applicable, and to advance expenses of such director or officer incurred in defending any proceeding covered by the indemnity.
The Registrant maintains a policy of directors' and officers' liability insurance that insures the directors and officers against the cost of defense, settlement or payment of a judgment under certain circumstances. The Registrant has also entered into indemnification agreements with its executive officers and directors that provide for the indemnification of directors and executive officers to the fullest extent permitted by the Washington Business Corporation Act against expenses reasonably incurred by such persons in any threatened, pending or completed action, suit, investigation or proceeding in connection with their service as (i) a director or officer or (ii) a director, officer, employee or agent of another

corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, at the Registrant's request. In addition, the indemnification agreements provide the Registrant with the obligation to advance expenses under certain circumstances and provide for procedural protections, including a determination by a reviewing party as to whether the indemnitee is permitted to be indemnified under applicable law. In addition, the Registrant acknowledges that it will be the indemnitor of first resort should the indemnitee have rights to indemnification provided by other persons.
Item 15.   Recent Sales of Unregistered Securities.
Set forth below is information regarding securities issued and options granted by us since January 1, 2014 that were not registered under the Securities Act of 1933, as amended, or the Securities Act. Also included is the consideration, if any, received by the Registrant, for such securities and options and information relating to the Securities Act, or rule of the SEC, under which exemption from registration was claimed.

These issuances of securities were deemed to be exempt from registration under the Securities Act in reliance on Rule 701 in that the transactions were under compensatory benefit plans and contracts relating to compensation as provided under Rule 701. Appropriate legends were affixed to the securities issued in these transactions.
​
(2)
From June 30, 2015 to June 30, 2018, the Registrant granted stock options under its 2016 Stock Incentive Plan to purchase an aggregate of 1,109,872 shares of common stock (net of expirations and cancellations) to its employees, directors and consultants, having exercise prices ranging from $0.73 to $14.30 per share, of which no shares have been exercised through the date hereof.

In February 2016, pursuant to the terms of an Asset Purchase Agreement, dated January 4, 2016, the Registrant issued warrants to purchase up to an aggregate of 17,000 shares of its common stock at an exercise price of  $120.00 per share to former shareholders of Novolytics Limited. The offers, sales and issuances were deemed to be exempt from registration under the Securities Act. The purchasers of securities in each of these transactions acquired the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the securities issued in these transactions. Each of such purchasers was an "accredited investor" under Rule 506 of Regulation D or not a "U.S. person" under Regulation S.
​
(4)
On April 8, 2016, pursuant to the terms of a Common Stock Issuance Agreement, the Registrant issued 85,346 shares of its common stock to certain former holders of its Series B redeemable convertible preferred stock. As consideration for the common stock issued and the amendments to certain warrants to purchase common stock, the recipients waived their right to receive approximately $2.2 million in aggregate cash payments to which they were entitled upon the conversion of their shares of Series B redeemable convertible preferred stock in respect of accrued dividends on their former shares of Series B redeemable convertible preferred stock. The recipients also waived their registration rights with respect to certain future registration statements that may be filed, and certain future public offerings that may be conducted, by the Registrant. The issuance of shares of common stock under the Common Stock Issuance Agreement was deemed to be exempt from registration under the Securities Act. Each of the recipients of such shares acquired the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the securities issued in these transactions. Each recipient was also an "accredited investor" under Rule 506 of Regulation D or not a "U.S. person" under Regulation S.

Item 17.   Undertakings.
The undersigned Registrant hereby undertakes to provide to the underwriter at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each investor.
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 SEC 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.
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;
​
​

TABLE OF CONTENTS
(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 20 percent 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;
​
(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 therein, 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.
​
(4)
That, for the purpose of determining liability under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
​
(i)
Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424 (§230.424 of this chapter);
​
(ii)
Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;
​
(iii)
The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and
​
(iv)
Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.
​
(5)
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 Securities Exchange Act of 1934, as amended, or 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 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
​
(6)
For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
