Enrollment of the trial was completed in September 2016 with a total of 515 subjects. Dosing in the trial was completed in April of 2017 and the one-year follow-up period was completed in September 2017. The primary endpoint of the trial is a composite of overall mortality and CMV end organ disease which will be assessed one year after transplantation. Astellas expects top-line data to be available in the first quarter of 2018.

Recruitment into the Phase 2 trial of VCL-HB01 has been completed with a total of 261 subjects enrolled at 15 U.S. clinical sites. The four-dose vaccination series was completed in July 2017, and all active subjects are currently being monitored for lesion recurrences during a 12-month follow-up period.&nbsp;&nbsp;VCL-HB01 is formulated with Vaxfectin&#174; and encodes two full-length HSV-2 antigens gD and UL46, designed to reduce recurrences in patients with symptomatic genital HSV-2 infection. Healthy adult subjects, 18 to 50 years of age, have been randomized 2:1 to receive either vaccine or placebo to evaluate in a double-blinded fashion the efficacy and safety of the vaccine. The primary endpoint of the study is annualized lesion recurrence rate which is a clinically meaningful endpoint for both patients and treating physicians as it provides important information on the number of recurrences over time in this chronic disease setting. We expect to announce top-line data during the second quarter of 2018.</font></p></td></tr></table></div>

The randomized, double-blind, placebo-controlled trial evaluated safety, tolerability and pharmacokinetics of single and multiple ascending doses of intravenous VL-2397 in 96 healthy volunteers. Results point to a favorable safety and pharmacokinetic profile for VL-2397. The full data set was presented as one of four presentations at the ASM Microbe 2017 conference in June. The U.S. Food and Drug Administration, or FDA, has advised us that VL&#8209;2397 would be eligible for a Limited Use Indication, or LUI, approval assuming a successful outcome of a single Phase 2 trial carried out in accordance with a protocol and statistical analysis plan consistent with the FDA&#8217;s advice. The final determination of whether VL-2397 is approvable will be made by the FDA after review of all relevant data. We plan to initiate a Phase 2 trial for the treatment of invasive aspergillosis in acute leukemia patients and&#160;allogeneic hematopoietic cell transplant recipients in the fourth quarter of 2017. The FDA has granted us qualified infectious disease product, or QIDP, Orphan Drug and Fast Track designations with respect to VL-2397 for the treatment of invasive aspergillosis.</font></p></td></tr></table></div>

Prior to making a decision about investing in our securities, you should carefully consider the risks described below, together with all of the other information included or incorporated by reference in this prospectus, including the risks described in the section entitled &#8220;Risk Factors&#8221; contained in our most recent quarterly report on Form 10-Q, which has been filed with the SEC and is incorporated by reference in this prospectus, as well as any updates thereto contained in subsequent filings with the SEC or any free writing prospectus. If any of these risks were to occur, our business, financial condition or results of operations would likely suffer. In that event, the value of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties we describe are not the only ones facing us. Additional risks not presently known to us or that we currently deem immaterial may also impair our business, financial condition or results of operations.</font></p>

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. </p>

We do not expect to sell any <font style="color:#000000;">pharmaceutical</font> products for at least the next several years. Our net losses were approximately $9.0 million, $9.2&#160;million and $16.5&#160;million for the years ended December&#160;31, 2016, 2015 and 2014, respectively. As of December 31, 2016, we had incurred cumulative net losses totaling approximately $413.9 million. Moreover, we expect that our net losses will continue and may increase for the foreseeable future. We may not be able to achieve projected results if we generate lower revenues or receive lower investment income than expected, or we incur greater expenses than expected, or all of the above. Currently our revenues are largely dependent on manufacturing and research services performed under our license agreement with Astellas. That revenue may decrease once the ASP0113 trials are complete or in the event that the development of the ASP0113 program ceases.&#160;&#160;We may never generate sufficient product revenue to become profitable. We also expect to have quarter-to-quarter fluctuations in revenues, expenses, and losses, some of which could be significant.</p>

We may seek additional funds through public and private stock offerings, government contracts and grants, arrangements with corporate collaborators, borrowings under lines of credit or other sources. We currently have on file a shelf registration statement that allows us to raise up to an aggregate of $100.0 million from the sale of common stock, preferred stock, debt securities and/or warrants subject to applicable rules under the Securities Act of 1933, as amended. However, we may not be able to raise additional funds on favorable terms, or at all. Conditions in the credit markets and the financial services industry may make equity and debt financing more difficult to obtain, and may negatively impact our ability to complete financing transactions. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants, such as limitations on our ability to incur additional indebtedness and other operating restrictions that could adversely impact our ability to conduct our business.</p>

(doing business as Brinson Patrick, a division of IFS Securities, Inc.), or BP, under which we may issue and sell up to $10.0 million of shares of our common stock from time to time. As of October 10, 2017, we had sold 1,509,370 shares of our common stock under the ATM Agreement and have received gross proceeds of approximately $4.3 million. BP is not obligated to sell any shares that we may request to be sold, and any attempt to sell shares under this facility, if made, may not be successful or generate sufficient proceeds to meet our capital requirements.</p>

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.</p>

Section&#160;145 of the Delaware General Corporation Law, or the DGCL, provides that a Delaware corporation may indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person was an officer, director, employee or agent of such corporation, or is or was serving at the request of such person as an officer, director, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys&#8217; fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation&#8217;s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was illegal. A Delaware corporation may indemnify any persons who are, or are threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys&#8217; fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation&#8217;s best interests except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses which such officer or director has actually and reasonably incurred. Article X of our restated certificate of incorporation provides for indemnification of our directors and officers, and Article V of our amended and restated bylaws provides for indemnification of our directors, officers, employees and other agents, to the maximum extent permitted by the DGCL. We have entered into indemnification agreements with our officers and directors. In addition, we maintain a policy providing directors&#8217; and officers&#8217; liability insurance.</p>

PROSPECTUS SUMMARY

Overview
Our Company
We research and develop biopharmaceutical products, including those based on our patented DNA delivery technologies, for the prevention and treatment of serious or life-threatening diseases. We currently have three active product development programs, independent or partnered, in the clinical testing stage in the area of infectious disease comprised of:
•
An ongoing Phase 3 trial of ASP0113 for prevention of cytomegalovirus, or CMV, reactivation in hematopoietic stem cell transplant recipients in collaboration with Astellas Pharma Inc., or Astellas. Enrollment of the trial was completed in September 2016 with a total of 515 subjects. Dosing in the trial was completed in April of 2017 and the one-year follow-up period was completed in September 2017. The primary endpoint of the trial is a composite of overall mortality and CMV end organ disease which will be assessed one year after transplantation. Astellas expects top-line data to be available in the first quarter of 2018. We and Astellas continue to make progress towards a potential Biologics License Application filing in 2018.
•
An ongoing Phase 2 trial of VCL-HB01, our therapeutic DNA vaccine for reduction of genital herpes lesion recurrences caused by herpes simplex virus type 2, or HSV-2, infection. Recruitment into the Phase 2 trial of VCL-HB01 has been completed with a total of 261 subjects enrolled at 15 U.S. clinical sites. The four-dose vaccination series was completed in July 2017, and all active subjects are currently being monitored for lesion recurrences during a 12-month follow-up period.  VCL-HB01 is formulated with Vaxfectin® and encodes two full-length HSV-2 antigens gD and UL46, designed to reduce recurrences in patients with symptomatic genital HSV-2 infection. Healthy adult subjects, 18 to 50 years of age, have been randomized 2:1 to receive either vaccine or placebo to evaluate in a double-blinded fashion the efficacy and safety of the vaccine. The primary endpoint of the study is annualized lesion recurrence rate which is a clinically meaningful endpoint for both patients and treating physicians as it provides important information on the number of recurrences over time in this chronic disease setting. We expect to announce top-line data during the second quarter of 2018.
•
A completed first-in-human Phase 1 trial of our novel antifungal VL-2397. The randomized, double-blind, placebo-controlled trial evaluated safety, tolerability and pharmacokinetics of single and multiple ascending doses of intravenous VL-2397 in 96 healthy volunteers. Results point to a favorable safety and pharmacokinetic profile for VL-2397. The full data set was presented as one of four presentations at the ASM Microbe 2017 conference in June. The U.S. Food and Drug Administration, or FDA, has advised us that VL‑2397 would be eligible for a Limited Use Indication, or LUI, approval assuming a successful outcome of a single Phase 2 trial carried out in accordance with a protocol and statistical analysis plan consistent with the FDA's advice. The final determination of whether VL-2397 is approvable will be made by the FDA after review of all relevant data. We plan to initiate a Phase 2 trial for the treatment of invasive aspergillosis in acute leukemia patients and allogeneic hematopoietic cell transplant recipients in the fourth quarter of 2017. The FDA has granted us qualified infectious disease product, or QIDP, Orphan Drug and Fast Track designations with respect to VL-2397 for the treatment of invasive aspergillosis.

results
of operations would likely suffer. In that event, the value of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties we describe are not the only ones facing us. Additional risks not presently known to us or that we currently deem immaterial may also impair our business, financial condition or results of operations.

RISK FACTORS
An investment in our securities involves a high degree of risk. Prior to making a decision about investing in our securities, you should carefully consider the risks described below, together with all of the other information included or incorporated by reference in this prospectus, including the risks described in the section entitled "Risk Factors" contained in our most recent quarterly report on Form 10-Q, which has been filed with the SEC and is incorporated by reference in this prospectus, as well as any updates thereto contained in subsequent filings with the SEC or any free writing prospectus. If any of these risks were to occur, our business, financial condition or results of operations would likely suffer. In that event, the value of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties we describe are not the only ones facing us. Additional risks not presently known to us or that we currently deem immaterial may also impair our business, financial condition or results of operations.
Risks Related to this Offering
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.
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.
To date, we have not sold, or received approval to sell, any pharmaceutical products. We do not expect to sell any
pharmaceutical
products for at least the next several years. Our net losses were approximately $9.0 million, $9.2 million and $16.5 million for the years ended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016, we had incurred cumulative net losses totaling approximately $413.9 million. Moreover, we expect that our net losses will continue and may increase for the foreseeable future. We may not be able to achieve projected results if we generate lower revenues or receive lower investment income than expected, or we incur greater expenses than expected, or all of the above. Currently our revenues are largely dependent on manufacturing and research services performed under our license agreement with Astellas. That revenue may decrease once the ASP0113 trials are complete or in the event that the development of the ASP0113 program ceases.  We may never generate sufficient product revenue to become profitable. We also expect to have quarter-to-quarter fluctuations in revenues, expenses, and losses, some of which could be significant.
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 NASDAQ Capital Market on           , 2017), and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. 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
4
number of shares offered by us,
we may need to raise additional capital sooner than we anticipate or may need to scale back or eliminate certain of our development programs
.
We may need to raise more money to continue the research and development necessary to bring our products to market and to establish marketing and additional manufacturing capabilities. We may seek additional funds through public and private stock offerings, government contracts and grants, arrangements with corporate collaborators, borrowings under lines of credit or other sources. We currently have on file a shelf registration statement that allows us to raise up to an aggregate of $100.0 million from the sale of common stock, preferred stock, debt securities and/or warrants subject to applicable rules under the Securities Act of 1933, as amended. However, we may not be able to raise additional funds on favorable terms, or at all. Conditions in the credit markets and the financial services industry may make equity and debt financing more difficult to obtain, and may negatively impact our ability to complete financing transactions. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants, such as limitations on our ability to incur additional indebtedness and other operating restrictions that could adversely impact our ability to conduct our business.
In October 2016, we also entered into an At-The-Market Issuance Sales Agreement, or the ATM Agreement, with IFS Securities, Inc. (doing business as Brinson Patrick, a division of IFS Securities, Inc.), or BP, under which we may issue and sell up to $10.0 million of shares of our common stock from time to time. As of October 10, 2017, we had sold 1,509,370 shares of our common stock under the ATM Agreement and have received gross proceeds of approximately $4.3 million. BP is not obligated to sell any shares that we may request to be sold, and any attempt to sell shares under this facility, if made, may not be successful or generate sufficient proceeds to meet our capital requirements.
If we are unable to obtain additional funds, we may have to scale back our development of new products, reduce our workforce or license to others products or technologies that we otherwise would seek to commercialize ourselves. The amount of money we may need would depend on many factors, including:
•
The progress of our research and development programs;
•
The scope and results of our preclinical studies and clinical trials;
•
The amount of our legal expenses and any settlement or damages payments associated with litigation; and
•
The time and costs involved in: obtaining necessary regulatory approvals; filing, prosecuting and enforcing patent claims; scaling up our manufacturing capabilities; and the commercial arrangements we may establish.
We may be unable to maintain compliance with the NASDAQ Marketplace Rules which could cause our common stock to be delisted from the NASDAQ Capital Market. This could result in the lack of a market for our common stock, cause a decrease in the value of an investment in us, and adversely affect our business, financial condition and results of operations.
Our common stock is currently listed on the NASDAQ Capital Market. To maintain the listing of our common stock on the NASDAQ Capital Market, we are required to meet certain listing requirements, including, among others, either: (i) a minimum closing bid price of $1.00 per share, a market value of publicly held shares (excluding shares held by our executive officers, directors and 10% or more stockholders) of at least $1 million and stockholders' equity of at least $2.5 million; or (ii) a minimum closing bid price of $1.00 per share, a market value of publicly held shares (excluding shares held by our executive officers, directors and 10% or more stockholders) of at least $1 million and a total market value of listed securities of at least $35 million. As of          , 2017, the closing sale price per share of our common stock was $          , the total market value of our publicly held shares of our common stock (excluding shares held by our executive officers, directors and 10% or more stockholders) was approximately $          million and the total market value of our listed securities was approximately $               million. There is no assurance that we will continue to meet the minimum closing price requirement and other listing requirements. As of June 30, 2017, we had stockholders' equity of approximately $39.8 million. Although NASDAQ may provide us with a compliance period in which to  regain compliance with the listing requirements, we cannot assure you that we would be able to regain compliance within the period provided by NASDAQ.
5
In the event that our common stock is delisted from NASDAQ and is not eligible for quotation or listing on another market or exchange, trading of our common stock could be conducted only in the o
ver-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or the OTC Bulletin Board. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our commo
n stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further.

USE OF PROCEEDS
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 NASDAQ Capital Market on          , 2017), and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.
A $0.10 increase (decrease) in the assumed public offering price of $           per share would increase (decrease) the 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.
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.
We currently intend to use the net proceeds from this offering for general corporate purposes, including clinical trial expenses, research and development expenses, general and administrative expenses, manufacturing expenses, and potential acquisitions of companies and technologies that complement our business. See "Risk Factors" for a discussion of certain risks that may affect our intended use of the net proceeds from this offering.
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 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.

DESCRIPTION OF CAPITAL STOCK
As of the date of this prospectus, our restated certificate of incorporation authorizes us to issue 50,000,000 shares of common stock, par value $0.01 per share and 5,000,000 shares of preferred stock, par value $0.01 per share. As of June 30, 2017, 11,226,209 shares of common stock were outstanding and no shares of preferred stock were outstanding.
The following summary describes the material terms of our capital stock.  The description of capital stock is qualified by reference to our restated certificate of incorporation and our amended and restated bylaws, which are exhibits to this prospectus.
Common Stock
The description of our common stock contained in our Registration Statement on Form 8-A filed with the SEC on January 8, 1993 is incorporated herein by reference in its entirety, as well as any amendment or update thereto reflected in subsequent filings with the SEC.  See "Incorporation of Certain Information by Reference."
Preferred Stock
Under our restated certificate of incorporation, our board of directors is authorized to issue additional shares of our preferred stock from time to time, in one or more classes or series, without stockholder approval. Prior to the issuance of shares of each class or series, our board of directors is required by the Delaware General Corporation Law, or the DGCL, and our restated certificate of incorporation to adopt resolutions and file a certificate of designation with the Delaware Secretary of State. The certificate of designation fixes for each class or series the designations, powers, preferences, rights, qualifications, limitations and restrictions of that class or series, including the following:
•
the number of shares constituting each class or series;
•
voting rights;
•
rights and terms of redemption, including sinking fund provisions;
•
dividend rights and rates;
•
terms concerning the distribution of assets;
•
conversion or exchange terms;
•
redemption prices; and
•
liquidation preferences.
We currently have on file a shelf registration statement that allows us to raise up to approximately $100.0 million from the sale of common stock, preferred stock, debt securities and/or warrants and our restated certificate of incorporation authorizes us to issue up to 5,000,000 shares of preferred stock. The issuance of preferred stock could adversely affect the voting power of holders of our common stock, and reduce the likelihood that our common stockholders will receive dividend payments and payments upon liquidation. The issuance of preferred stock could also decrease the market price of our common stock, or have terms and conditions that could discourage a takeover or other transaction that might involve a premium price for our shares or that our stockholders might believe to be in their best interests.
Anti-Takeover Provisions
Delaware Anti-Takeover Law
We are subject to Section 203 of the DGCL. Section 203 generally prohibits a public Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:
10
•
prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction that resulted
in the stockholder becoming an interested stockholder;
•
the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also officers of the corporation and (b) shares issued under employee stock plans under which employee participants do not have the right to determine whether shares held subject to the plan will be tendered in a tender or exchange offer; or
•
on or subsequent to the date of the transaction, the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66
2
⁄
3
% of the outstanding voting stock that is not owned by the interested stockholder.
Section 203 defines a business combination to include:
•
any merger or consolidation involving the corporation and the interested stockholder;
•
any sale, transfer, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;
•
subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
•
any transaction involving the corporation that has the effect of increasing the proportionate share of its stock owned by the interested stockholder; or
•
the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.
In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.
Certificate of Incorporation and Bylaws
Some provisions of our restated certificate of incorporation and amended and restated bylaws could also have anti-takeover effects. These provisions:
•
provide for a board comprised of three classes of directors with each class serving a staggered three-year term;
•
authorize our board of directors to issue preferred stock from time to time, in one or more classes or series, without stockholder approval;
•
require the approval of at least two-thirds of our outstanding voting stock to amend specified provisions of our certificate of incorporation;
•
require the approval of at least two-thirds of our total number of authorized directors, or two-thirds of our outstanding voting stock, to amend our bylaws;
•
provide that special meetings of our stockholders may be called only by our Chief Executive Officer, or by our board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors; and
•
do not include a provision for cumulative voting for directors (under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares may be able to ensure the election of one or more directors).
In addition, in August 2016, we completed a private placement of our common stock to AnGes MG, Inc., or AnGes, immediately following which AnGes owned approximately 18.6% of our outstanding shares.  In connection with the
11
private placement, AnGes agreed to vote all of its shares in acco
rdance with the recommendations of our board of directors on any matter brought before our stockholders for a vote, subject to certain limitations.  This voting provision may also discourage or prevent attempts by other stockholders to replace members of o
ur board of directors or engage in acquisition activities that our board of directors does not determine to be in the best interests of our stockholders.
NASDAQ Capital Market Listing
Our common stock is listed on the NASDAQ Capital Market under the symbol "VICL."

UNDERWRITING
We have entered into an underwriting agreement dated              , 2017, with H.C. Wainwright & Co., LLC as the sole book-running manager of this offering. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to the underwriter and the underwriter has agreed to purchase from us, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus,               shares of our common stock.
A copy of the underwriting agreement has been filed as an exhibit to the registration statement of which this prospectus is a part. The shares of common stock we are offering are being offered by the underwriter subject to certain conditions specified in the underwriting agreement.
We have been advised by the underwriter that it proposes to offer the shares directly to the public at the public offering price set forth on the cover page of this prospectus. Any shares sold by the underwriter to securities dealers will be sold at the public offering price less a selling concession not in excess of $           per share.
The underwriting agreement provides that the underwriter's obligation to purchase the securities we are offering is subject to conditions contained in the underwriting agreement. The underwriter is obligated to purchase and pay for all of the shares offered by this prospectus.
No action has been taken by us or the underwriter that would permit a public offering of the common stock in any jurisdiction where action for that purpose is required. None of the shares included in this offering may be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sales of any of the shares be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons who receive this prospectus are advised to inform themselves about and to observe any restrictions relating to this offering of the common stock and the distribution of this prospectus. This prospectus is neither an offer to sell nor a solicitation of any offer to buy the common stock in any jurisdiction where that would not be permitted or legal.
The underwriter has advised us that it does not intend to confirm sales to any accounts over which it exercises discretionary authority.
Underwriting Discounts, Commissions and Expenses
The following table shows the public offering price, underwriting discounts and commissions and proceeds, before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriter's option to purchase additional shares.

Tail
13
We have also agreed to a tail fee equal to the cash compensation in this offering if any investor to which the underwriter contacted or introduced us with respect to this offering during the term of its enga
gement provides us with further capital in a public or private offering or capital raising transaction, with certain exceptions, during the 5-month period following termination of our engagement of the underwriter.
Option to Purchase Additional Shares
We have granted to the underwriter an option, exercisable not later than 30 days after the date of this prospectus, to purchase up to an additional               shares of common stock at the public offering price, less the underwriting discounts and commissions, set forth on the cover page of this prospectus
, to cover over-allotments, if any
. If any additional shares of common stock are purchased pursuant to the option to purchase additional shares, the underwriter will offer these shares of common stock on the same terms as those on which the other shares of common stock are being offered hereby.
NASDAQ Capital Market Listing
Our stock is currently traded on the NASDAQ Capital Market under the symbol "VICL." On October 13, 2017, the closing price of our common stock was $2.82 per share.
Lock-up Agreements
Our officers and directors have agreed with the underwriter to be subject to a lock-up period of 90 days following the date of this prospectus. This means that, during the applicable lock-up period, such persons may not offer for sale, contract to sell, sell, distribute, grant any option, right or warrant to purchase, pledge, hypothecate or otherwise dispose of, directly or indirectly, any shares of our common stock or any securities convertible into, or exercisable or exchangeable for, shares of our common stock. Certain limited transfers are permitted during the lock-up period if the transferee agrees to these lock-up restrictions. We have also agreed, in the underwriting agreement, to similar lock-up restrictions on the issuance and sale of our securities for 90 days following the closing of this offering, although we will be permitted to issue stock options or stock awards to directors, officers, employees and consultants under our existing plans. The underwriter may, in its sole discretion and without notice, waive the terms of any of these lock-up agreements.
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 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 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 common stock. These transactions may be effected on the
14
NASDAQ Capital Market, 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 common stock in accordance with Regulation M during a period before the commencement of offers or sales of shares of our 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.
Indemnification
We have agreed to indemnify the underwriter against certain liabilities, including certain liabilities arising under the Securities Act, or to contribute to payments that the underwriter may be required to make for these liabilities.
Other Relationships
The underwriter and its respective affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. The underwriter has received, or may in the future receive, customary fees and commissions for these transactions.

Item 14. Indemnification of Directors and Officers.
We are incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law, or the DGCL, provides that a Delaware corporation may indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person was an officer, director, employee or agent of such corporation, or is or was serving at the request of such person as an officer, director, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation's best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was illegal. A Delaware corporation may indemnify any persons who are, or are threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation's best interests except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses which such officer or director has actually and reasonably incurred. Article X of our restated certificate of incorporation provides for indemnification of our directors and officers, and Article V of our amended and restated bylaws provides for indemnification of our directors, officers, employees and other agents, to the maximum extent permitted by the DGCL. We have entered into indemnification agreements with our officers and directors. In addition, we maintain a policy providing directors' and officers' liability insurance.
II-1
Section 102 of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for bre
ach of fiduciary duties as a director, except for liability:
•
for any breach of the director's duty of loyalty to the corporation or its stockholders;
•
for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;
•
for acts related to unlawful stock repurchases, redemptions or other distributions or payment of dividends; or
•
for any transaction from which the director derived an improper personal benefit.
Our restated certificate of incorporation and amended and restated bylaws include such a provision. Expenses incurred by any officer or director in defending any such action, suit or proceeding in advance of its final disposition shall be paid by us upon delivery to us of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified by us.
Item 15. Recent Sales of Unregistered Securities.
Set forth below is information regarding securities issued 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 us, for such securities and information relating to the Securities Act, or rule of the SEC, under which exemption from registration was claimed.
On March 24, 2015, we entered into a license agreement with Astellas Pharma Inc., or Astellas, granting us an exclusive, worldwide license to develop and commercialize VL-2397.  In connection with the equity payments contemplated by the license agreement, on March 24, 2015, we entered into a separate stock purchase agreement with Astellas, or the Stock Purchase Agreement.  Pursuant to the Stock Purchase Agreement, we issued an aggregate of 86,121 unregistered shares of our common stock to Astellas at a per share purchase price of approximately $10.01, in partial consideration for the rights granted to us under the license agreement.
The shares of our common stock issued to Astellas under the Stock Purchase Agreement were issued pursuant to the exemption from the registration requirements of the Securities Act afforded by Section 4(a)(2) of the Securities Act and/or Rule 506 of Regulation D promulgated thereunder, as a transaction to an accredited investor not involving a public offering.  Astellas represented to us that its intention was to acquire the securities for investment only and not with a view to the resale or distribution of the securities.
On August 1, 2016, we entered into a stock purchase agreement with AnGes, pursuant to which AnGes purchased 1,841,420 unregistered shares of our common stock at a per share price of $4.2448, or the AnGes Stock Purchase Agreement.  The shares of our common stock issued to AnGes under the AnGes Stock Purchase Agreement were issued pursuant to the exemption from the registration requirements of the Securities Act afforded by Section 4(a)(2) of the Securities Act, as a transaction to an accredited investor not involving a public offering.  AnGes represented to us that it intended to acquire the securities for investment only and not with a view to the resale or distribution of the securities.

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 purchaser.
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;
(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 underwriting 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;
II-3
(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)
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.
(6)
For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus 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.
