PROSPECTUS SUMMARY

This summary highlights certain information about us, this offering and selected information contained elsewhere in or incorporated by reference into this prospectus. This summary is not complete and does not contain all of the information that you should consider in making your investment decision. For a more complete understanding of our company and this offering, you should read carefully this entire prospectus, including the information incorporated by reference into this prospectus, and any free writing prospectus prepared by or on our behalf that we have authorized for use in connection with this offering, including the “Risk Factors” section beginning on page S-7 of this prospectus supplement, page 6 of the accompanying base prospectus, our consolidated financial statements and the related notes thereto and the other documents incorporated by reference into this prospectus.

Our Company

We are a clinical-stage biotechnology company engaged in the discovery and development of targeted biotherapeutics to treat serious diseases and conditions with unmet medical needs, including cancer, neurodegenerative diseases, and autoimmune disorders. We believe we are the leader in the field of semaphorin 4D, or SEMA4D, biology and that we are the only company targeting SEMA4D as a potential treatment for cancer, neurodegenerative diseases, or autoimmune disorders. SEMA4D is an extracellular signaling molecule that regulates the migration of immune and inflammatory cells to sites of injury, cancer or infection. We are leveraging our SEMA4D antibody platform and our extensive knowledge of SEMA4D biology to develop our lead product candidate, pepinemab (also known as VX15/2503), an antibody that we believe utilizes novel mechanisms of action. We are focused on the development of pepinemab for the treatment of non-small cell lung cancer, or NSCLC, Huntington’s disease, or HD, and Alzheimer’s disease, or AD. Additionally, third party investigators are studying pepinemab in clinical trials in osteosarcoma and melanoma as well as in “window of opportunity” studies in other indications. We have developed multiple proprietary platform technologies and are developing product candidates to address serious diseases or conditions that have a substantial impact on day-to-day functioning and for which treatment is not addressed adequately by available therapies. We employ our proprietary platform technologies, including through our work with our academic collaborators, to identify potential product candidates for sustained expansion of our internal product pipeline and to facilitate strategic development and commercial partnerships.

Our lead platform technologies include our SEMA4D antibody platform and our ActivMAb antibody discovery platform.

 

   

Our SEMA4D antibody platform is the application of our extensive knowledge of SEMA4D biology to develop our lead product candidate pepinemab for the treatment of various indications, including cancer and neuroinflammatory and neurodegenerative diseases. Pepinemab’s mechanisms of action block the SEMA4D signal and activate innate physiological mechanisms to respond to tumors or tissue injury. We have demonstrated in preclinical studies in animal models that the biological activities associated with an antibody blockade of SEMA4D can promote immune cell infiltration into tumors and the repair or prevention of neurological damage in neuroinflammatory and neurodegenerative diseases.

 

   

Our ActivMAb® antibody discovery platform is a proprietary human antibody discovery platform based on a novel method for expressing large and diverse libraries of high affinity, full-length human monoclonal antibodies on the surface of vaccinia, a mammalian virus. We believe our ActivMAb technology offers (i) rapid generation of high affinity, full-length, human monoclonal antibodies synthesized and naturally modified in mammalian cells, (ii) expression and selection of antibodies that easily and predictably transition to manufacturing in mammalian lines, and (iii) an innovative and efficient method for selecting antibodies against multi-pass membrane proteins, an important class of

pharmacological targets. Our product candidate VX5 was generated by our ActivMAb platform and is currently in preclinical development for the treatment of MS and potentially for other autoimmune disorders. We intend to continue to utilize our ActivMAb platform to identify additional product candidates for our own pipeline development and for strategic collaborations.

In addition, we and our academic collaborators are using our Natural Killer T, or NKT, vaccine platform to discover product candidates that target and extend the activity of NKT cells. NKT cells work directly to kill certain types of parasites and cells, including tumor cells and virus-infected cells. We are applying our agonists to direct NKT cells to the site of tumors, potentially enhancing tumor-specific immunity through recruitment and activation of cytotoxic T cells, or CTL, and antibody-armed natural killer, or NK, cells that will work to eradicate the tumor.

Vaccinex Product Pipeline

 

LOGO

Pepinemab is currently in clinical development by us for the treatment of NSCLC, and HD, in investigator-sponsored trials, or ISTs, for the treatment of osteosarcoma and melanoma, and in multiple “window of opportunity” studies in other indications. Our additional product candidates, VX5 and VX25, are in earlier stages of development and were generated using our ActivMAb and NKT vaccine platforms, respectively. VX5 is a human antibody to CXCL13, a molecule that regulates the formation of immune tissues, and is currently in preclinical development for the treatment of MS and potentially for other autoimmune disorders. VX25, a bi-specific NKT cell stimulator, is being evaluated in various preclinical cancer models and seeks to address challenges for the therapeutic application of NKT cell stimulation for cancer immunotherapy. We believe our multiple platform technologies position us well for continued pipeline expansion and partnership opportunities going forward.

Pepinemab

Pepinemab is a humanized monoclonal antibody that binds and blocks the signaling activity of SEMA4D. We are advancing pepinemab with what we believe to be novel mechanisms of action for the treatment of cancer and certain neurodegenerative diseases, including HD. As of December 31, 2019, 521 patients have been treated or enrolled in seven Phase 1 clinical trials and two Phase 2 clinical trials of pepinemab in separate indications.

Cancer

Pepinemab is currently being studied as a treatment for advanced solid tumors, including in clinical trials in NSCLC, osteosarcoma, and melanoma. We have demonstrated in preclinical tumor models that SEMA4D regulates infiltration of immune precursor cells into tumor tissue. Our preclinical data suggest that blocking SEMA4D promotes infiltration of immune cells that can eradicate the tumor. We have also demonstrated in preclinical models the potential for synergy between pepinemab and a checkpoint inhibitor when used in combination. We completed a Phase 1 clinical trial of pepinemab as a single-agent cancer therapy and released top-line data in October 2014. Pepinemab was well tolerated in this clinical trial.

In October 2017 in collaboration with Merck KGaA, we initiated the CLASSICAL–Lung clinical trial, a Phase 1b/2 clinical trial of pepinemab in combination with avelumab, an inhibitor of the PD-1/PD-L1 checkpoint pathway, in patients with NSCLC who have not previously been treated with immunotherapy. In July 2018, an additional cohort of patients who failed prior immunotherapy was added to the trial. The CLASSICAL-Lung trial consists of a dose escalation phase and a subsequent dose expansion phase. We announced in August 2019 that we had completed enrollment in the dose expansion phase. We anticipate near topline data for this trial in the first half of 2020.

In February 2018, The Children’s Oncology Group, or COG, with financial support from the National Cancer Institute, initiated a Phase 1/2 clinical trial of pepinemab as a single agent in pediatric patients with recurrent, relapsed, or refractory solid tumors, including osteosarcoma. In March 2020, COG notified us of its intention to discontinue this study. In June 2018, a Phase 1 IST of pepinemab in combination with Yervoy® or with Opdivo® began at the UCLA Jonsson Comprehensive Cancer Center in patients with advanced melanoma who have progressed on prior anti-PD-1/PD-L1 based therapies. In addition, Emory University has initiated three separate Phase 1 IST “window of opportunity” studies evaluating pepinemab as a single agent and in combination with ipilimumab or nivolumab in multiple other indications. We anticipate that we will present interim analysis of these window of opportunity studies at the American Society of Clinical Oncology, or ASCO, Annual Meeting in May/June 2020.

Huntington’s Disease

We are studying pepinemab as a treatment for HD, which is a neurodegenerative genetic disorder that typically manifests in mid-adult life. Our study of pepinemab in HD is based on our prior research of neurodegenerative disease mechanisms, in which we demonstrated in preclinical models that SEMA4D triggers activation of both microglia and astrocytes, the innate inflammatory cells of the central nervous system, or CNS. The chronic activation of microglia and astrocytes has been implicated as an important disease mechanism in HD, Alzheimer’s disease, or AD, progressive MS, and other neurodegenerative disorders. We initiated the SIGNAL study, a Phase 2 clinical trial, in July 2015 in early manifest and late prodromal (pre-manifest) HD patients. This clinical trial builds on preclinical studies in an animal model of HD and safety data from a Phase 1 dose-escalation clinical trial of pepinemab in MS patients that we completed in November 2014. The SIGNAL study has an adaptive design, and interim analysis of Cohort A data for 36 randomized patients was completed in April 2017. Data from this cohort showed that treatment with pepinemab induced a sharp increase in glucose metabolism in the brain during HD disease progression as detected by conventional FDG-PET imaging. On the



 

S-3


Table of Contents

basis of this data, the design of the Cohort B study was modified, and enrollment in Cohort B was completed in December 2018. We anticipate publication of data from Cohort A of the SIGNAL trial in the second half of 2020. Cohort B includes a total of 265 subjects in two cohorts: 179 patients who have early manifest disease, and 86 who are late prodromal. All subjects are randomized to receive monthly infusions of either pepinemab or placebo for 18 months in double-blind fashion without crossover. The estimated primary completion date, which is the date on which the last participant in a clinical study is examined or receives an intervention to collect the final data for the primary outcome measure, for the SIGNAL Phase 2 trial is the second half of 2020, with topline data expected in October 2020. The U.S. Food and Drug Administration, or FDA, has granted both Orphan Drug designation and Fast Track designation to pepinemab for HD.

Alzheimer’s Disease

We intend to initiate a clinical study of pepinemab as a potential treatment for AD in 2020. This study of pepinemab in AD, which we refer to as “SIGNAL-AD,” will be based on our prior research of neurodegenerative disease mechanisms in which we demonstrated in preclinical models that SEMA4D triggers activation of both microglia and astrocytes. In December 2019, we announced a funding grant of $750,000 from the Alzheimer’s Association and an award in the form of investment in our common stock of up to $3 million from the Alzheimer’s Drug Discovery Foundation, each in support of SIGNAL-AD. We expect to receive the funding in 2020. As noted above, the chronic activation of microglia and astrocytes has been implicated as an important disease mechanism in AD as well as in other neurodegenerative disorders. The design for this study is based on evidence from Cohort A of the SIGNAL clinical trial in HD showing that treatment with pepinemab induced a sharp increase in glucose metabolism in the brain during HD disease progression as detected by conventional FDG-PET imaging. Previous studies in AD have shown that decline in glucose metabolism correlates with cognitive decline. Recently, it has been reported that FDG-PET is superior to the more established Aß amyloid-PET as an indicator of cognitive decline in early AD, which gives us greater confidence in relying on the evidence from Cohort A of our SIGNAL clinical trial in HD to inform the SIGNAL-AD trial. SIGNAL-AD will be a 60 patient, randomized, placebo-controlled, multi-center phase 1b clinical study. We had intended to enroll the first patient in this trial in mid-2020, with top-line data anticipated early 2022. However, the initial enrollment date is now delayed subject to evaluating further developments and risks related to the COVID-19 coronavirus.

For as long as we remain an “emerging growth company,” we may take advantage of certain exemptions from various reporting requirements that are applicable to public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation and financial statements in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote to approve executive compensation and shareholder approval of any golden parachute payments not previously approved. We may take advantage of one or more of these reporting exemptions until we are no longer an “emerging growth company.”

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, and we have elected to do so.

We have filed a shelf registration statement on Form S-3 with the SEC of which this prospectus supplement and accompanying prospectus are a part. In order to issue securities under this registration statement, we must rely on Instruction I.B.6 of Form S-3, which imposes a limitation on the maximum amount of securities that we may offer and sell pursuant to the registration statement during any twelve-month period. At the time we offer securities pursuant to the registration statement, the amount of securities to be offered and sold plus the amount of any securities we have offered and sold during the prior twelve months in reliance on Instruction I.B.6 may not exceed one-third of the aggregate market value of our outstanding common stock held by non-affiliates

as of a day during the 60 days immediately preceding such sale, as computed in accordance with Instruction I.B.6. After giving effect to this offering, we will be substantially limited in our ability to effect any other offering pursuant to our effective registration statement on Form S-3 in the near term, unless and until the market value of our outstanding common stock held by non-affiliates increases significantly. If we cannot sell securities under our shelf registration statement, we may be required to utilize more costly and time-consuming means of accessing the capital markets, which could materially adversely affect our liquidity and cash position.

We have broad discretion in how we use the net proceeds of this offering, and we may not use these proceeds effectively or in ways with which you agree.

Our management will have broad discretion as to the use of the net proceeds from this offering. 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. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds will be used appropriately. These net proceeds could be applied in ways that do not improve our operating results or increase the value of your investment. See “Use of Proceeds” on page S-10 of this prospectus supplement for a description of our proposed use of proceeds from this offering.

Investors in this offering will experience immediate dilution in the book value per share of the common stock purchased in the offering.

The common stock sold in this offering, if any, will be sold from time to time at various prices. However, the expected offering price of our common stock will be substantially higher than the net tangible book deficit per share of our outstanding common stock. After giving effect to the sale of shares of our common stock in the aggregate amount of $11.5 million at an assumed offering price of $4.40 per share, the last reported sale price of our common stock on March 25, 2020 on the Nasdaq Capital Market, and after deducting estimated commissions and estimated offering expenses, our as-adjusted net tangible book value as of December 31, 2019 would have been approximately $8.7 million, or approximately $0.50 per share. This represents an immediate increase in net tangible book value of approximately $0.65 per share to our existing shareholders and an immediate dilution in as-adjusted net tangible book deficit of approximately $3.90 per share to new investors participating in this offering. See “Dilution” on page S-11 of this prospectus supplement.

The actual number of shares we will issue under the sales agreement with Jefferies, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement with Jefferies and compliance with applicable law, we have the discretion to deliver placement notices to Jefferies at any time throughout the term of the sales agreement. The number of shares that are sold by Jefferies after delivering a placement notice will fluctuate based on the market price of the common stock during the sales period and limits we set with Jefferies.

We do not expect to pay dividends in the foreseeable future. As a result, you must rely on stock appreciation for any return on your investment.

We have never paid do not anticipate paying cash dividends on shares of our common stock in the foreseeable future. Any payment of cash dividends will also depend on our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors. Accordingly, you will have to rely on capital appreciation, if any, to earn a return on your investment in our common stock. Furthermore, we may in the future become subject to additional contractual restrictions on, or prohibitions against, the payment of dividends.

The COVID-19 coronavirus could adversely impact our business, including our clinical development plans.

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China. Since then, the COVID-19 coronavirus has spread to multiple countries, including the United States, and has caused significant disruptions around the world. For example, we had previously anticipated beginning enrollment in mid-2020 in our study of pepinemab in AD, but the initial enrollment date is now delayed, the extent of such delay is subject to evaluating further developments and risks related to COVID-19. We may experience further disruptions as a result of the COVID-19 pandemic that could severely impact our business, including:

 

   

interruption of key manufacturing, research and clinical development activities due to limitations on work and travel imposed or recommended by federal or state governments, employers and others;

 

   

delays or difficulties in clinical trial site operations, including difficulties in recruiting clinical site investigators and clinical site staff and difficulties in enrolling patients or treating patients in active trials;

 

   

interruption of key business activities due to illness and/or quarantine of key individuals and delays associated with recruiting, hiring and training new temporary or permanent replacements for such key individuals, both internally and at our third party service providers;

 

   

delays in research and clinical trial sites receiving the supplies and materials needed to conduct preclinical studies and clinical trials, due to work stoppages, travel and shipping interruptions or restrictions or other reasons;

 

   

difficulties in raising additional capital needed to pursue the development of our programs due to the slowing of our economy and near term and/or long term negative effects of the pandemic on the financial, banking and capital markets;

 

   

changes in local regulations as part of a response to the COVID-19 coronavirus outbreak that may require us to change the ways in which research, including clinical development, is conducted, which may result in unexpected costs; and

 

   

delays in necessary interactions with regulators, ethics committees and other important agencies and contractors due to limitations in employee resources, travel restrictions or forced furlough of government employees.

The global outbreak of the COVID-19 coronavirus continues to rapidly evolve. The extent to which the COVID-19 coronavirus may impact our business will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the virus.

USE OF PROCEEDS

We may issue and sell our shares of common stock having aggregate sales proceeds of up to $[•] million from time to time. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. There can be no assurance that, in the future, we will sell any shares under or fully utilize the sales agreement with Jefferies as a source of financing.

We currently intend to use the net proceeds from this offering for the development of pepinemab for the treatment of NSCLC and other cancer indications including, in particular, HNSCC, and for neurodegenerative diseases including HD and AD, and for general corporate purposes, which may include working capital, capital expenditures, research and development expenditures and clinical trial expenditures, among other things.

The precise amount and timing of the application of these net proceeds will depend upon a number of factors, such as the timing and progress of our research and development efforts and the timing and progress of any partnering efforts. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds from this offering. Depending on the outcome of our efforts and other unforeseen events, our plans and priorities may change and we may apply the net proceeds of this offering in different manners than we currently anticipate. Accordingly, our management will have broad discretion in the timing and application of these net proceeds.

DILUTION

If you invest in our securities in this offering, you will experience immediate dilution to the extent of the difference between the price per share of our common stock in this offering and the net tangible book deficit per share of our common stock immediately after this offering. As of December 31, 2019, our historical net tangible book deficit was approximately $2.3 million, or $0.15 per share of our common stock. Our historical net tangible book deficit per share represents our total tangible assets less total liabilities, divided by the number of shares of our common stock outstanding as of December 31, 2019.

After giving effect to the assumed sale of our shares of common stock in the aggregate amount of $11.5 million at an assumed offering price of $4.40 per share, the last reported sale price of our common stock on March 26, 2020 on the Nasdaq Capital Market, and after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, our adjusted net tangible book value as of December 31, 2019 would have been approximately $8.7 million, or approximately $0.50 per share of our common stock. This amount represents an immediate increase in net tangible book value of $0.65 per share to our existing stockholders and immediate dilution of $3.90 per share of our common stock to purchasers in this offering. The following table illustrates this calculation on a per share basis:

 

Assumed public offering price per share of common stock

     $ 4.40  

Net tangible book value (deficit) per share as of December 31, 2019

   $ (0.15  

Increase in net tangible book value per share of common stock attributable to investors purchasing our common stock in this offering

     0.65    
  

 

 

   

Adjusted net tangible book value per share of common stock immediately after this offering

       0.50  
    

 

 

 

Dilution per share of common stock to investors purchasing shares of our common stock in this offering

     $ 3.90  
    

 

 

 

The number of shares of our common stock to be outstanding after this offering is based on 14,887,147 shares of our common stock outstanding as of December 31, 2019 and excludes:

 

   

1,468,563 shares of our common stock issued in a private placement on January 23, 2020;

 

   

579,731 shares of our common stock issuable upon the exercise of stock options outstanding as of December 31, 2019 at a weighted-average exercise price of $8.04 per share;

 

   

1,173,500 shares of our common stock issuable upon the exchange of Vaccinex Products, LP units;

 

   

1,318,787 shares of our common stock issuable upon the exchange of VX3 (DE) LLP units; and

 

   

230,952 shares of our common stock available for future issuance under our 2018 Omnibus Incentive Plan, or the 2018 Plan, as of December 31, 2019.

To the extent that any of our outstanding options are exercised, Vaccinex Products, LP or VX3 (DE) LLP units are exchanged, new options are issued under the 2018 Plan or pursuant to inducement awards, or we issue additional shares of common stock in the future, there will be further dilution to new investors participating in this offering. In addition, we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. If we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Jefferies, under which we may offer and sell shares of common stock from time to time through Jefferies acting as agent. Sales of our shares of common stock, if any, under this prospectus supplement and the accompanying prospectus will be made by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act.

Each time we wish to issue and sell shares of common stock under the sales agreement, we will notify Jefferies of the number of shares to be issued, the dates on which such sales are anticipated to be made, any limitation on the number of shares to be sold in any one day and any minimum price below which sales may not be made. Once we have so instructed Jefferies, unless Jefferies declines to accept the terms of such notice, Jefferies has agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such shares up to the amount specified on such terms. The obligations of Jefferies under the sales agreement to sell our shares of common stock are subject to a number of conditions that we must meet.

The settlement of sales of shares between us and Jefferies is generally anticipated to occur on the second trading day following the date on which the sale was made. Sales of our shares of common stock as contemplated in this prospectus supplement will be settled through the facilities of The Depository Trust Company or by such other means as we and Jefferies may agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We will pay Jefferies a commission equal to a rate of 3.0% of the aggregate gross proceeds we receive from each sale of our shares of common stock. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. In addition, we have agreed to reimburse Jefferies for the fees and disbursements of its counsel, payable upon execution of the sales agreement, in an amount not to exceed $50,000, in addition to certain ongoing disbursements of its legal counsel. We estimate that the total expenses for the offering, excluding any commissions or expense reimbursement payable to Jefferies under the terms of the sales agreement, will be approximately $162,000. The remaining sale proceeds, after deducting any other transaction fees, will equal our net proceeds from the sale of such shares.

Jefferies will provide written confirmation to us before the open on The Nasdaq Capital Market on the day following each day on which shares of common stock are sold under the sales agreement. Each confirmation will include the number of shares sold on that day, the aggregate gross proceeds of such sales and the proceeds to us.

In connection with the sale of the shares of common stock on our behalf, Jefferies will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation of Jefferies will be deemed to be underwriting commissions or discounts. We have agreed to indemnify Jefferies against certain civil liabilities, including liabilities under the Securities Act. We have also agreed to contribute to payments Jefferies may be required to make in respect of such liabilities.

The offering of our shares of common stock pursuant to the sales agreement will terminate upon the earlier of (i) the sale of all shares of common stock subject to the sales agreement and (ii) the termination of the sales agreement as permitted therein. We and Jefferies may each terminate the sales agreement at any time upon ten days’ prior notice.

This summary of the material provisions of the sales agreement does not purport to be a complete statement of its terms and conditions. A copy of the sales agreement will be filed as an exhibit to a current report on Form 8-K filed under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and will be incorporated by reference in this prospectus supplement.

THE COMPANY

Company Overview

We are a clinical-stage biotechnology company engaged in the discovery and development of targeted biotherapeutics to treat serious diseases and conditions with unmet medical needs, including cancer, neurodegenerative diseases, and autoimmune disorders. We believe we are the leader in the field of SEMA4D biology and that we are the only company targeting SEMA4D as a potential treatment for cancer, neurodegenerative diseases, or autoimmune disorders. SEMA4D is an extracellular signaling molecule that regulates the migration of immune and inflammatory cells to sites of injury, cancer or infection. We are leveraging our SEMA4D antibody platform and our extensive knowledge of SEMA4D biology to develop our lead product candidate, pepinemab (VX15), which we believe utilizes novel mechanisms of action. We are focused on the development of pepinemab for the treatment of non-small cell lung cancer, osteosarcoma, melanoma and Huntington’s disease. We have developed multiple proprietary platform technologies and are developing product candidates to address serious diseases or conditions that have a substantial impact on day-to-day functioning and for which treatment is not addressed adequately by therapies available on the market. We employ our proprietary platform technologies, including through our work with our academic collaborators, to identify potential product candidates for sustained expansion of our internal product pipeline and to facilitate strategic development and commercial partnerships.

Our lead platform technologies include our SEMA4D antibody platform and our ActivMAb antibody discovery platform.

 

   

Our SEMA4D antibody platform is the application of our extensive knowledge of SEMA4D biology to develop our lead product candidate pepinemab for the treatment of various indications, including cancer and neuroinflammatory and neurodegenerative diseases. We believe pepinemab’s mechanisms of action block the SEMA4D signal and activate innate physiological mechanisms to respond to tumors or tissue injury. We have demonstrated in animal models in preclinical studies that the biological activities associated with an antibody blockade of SEMA4D can promote immune cell infiltration into tumors and the repair or prevention of neurological damage in neuroinflammatory and neurodegenerative diseases.

 

   

Our ActivMAb® antibody discovery platform is a proprietary human antibody discovery platform based on a novel method for expressing large and diverse libraries of high affinity, full-length human monoclonal antibodies on the surface of vaccinia, a mammalian virus. We believe our ActivMAb technology offers (i) rapid generation of high affinity, full-length, human monoclonal antibodies synthesized and naturally modified in mammalian cells, (ii) expression and selection of antibodies that easily and predictably transition to manufacturing in mammalian lines, and (iii) an innovative and efficient method for selecting antibodies against multi-pass membrane proteins, an important class of pharmacological targets. Our product candidate VX5 was generated by our ActivMAb platform and is currently in preclinical development for the treatment of multiple sclerosis, or MS, and potentially for other autoimmune disorders. We intend to continue to utilize our ActivMAb platform to identify additional product candidates for our own pipeline development and for strategic collaborations.

In addition, we and our academic collaborators are using our Natural Killer T, or NKT, vaccine platform to discover product candidates that target and extend the activity of NKT cells. NKT cells work directly to kill certain types of parasites and cells, including tumor cells and virus-infected cells. We are applying our agonists to direct NKT cells to the site of tumors, potentially enhancing tumor-specific immunity through recruitment and activation of cytotoxic T cells and antibody-armed natural killer cells that will work to eradicate the tumor.

Vaccinex Product Pipeline

 

LOGO

Our lead product candidate pepinemab is currently in clinical development for the treatment of NSCLC, osteosarcoma, melanoma and Huntington’s disease, through our efforts or through investigator-sponsored trials, or ISTs. Our additional product candidates VX5 and VX25 are in earlier stages of development and were generated using our ActivMAb and NKT vaccine platforms, respectively. VX5 is a human antibody to CXCL13, a molecule that regulates the formation of immune tissues, and is currently in preclinical development for the treatment of MS and potentially for other autoimmune disorders. VX25, a bi-specific NKT cell stimulator, is being evaluated in various preclinical cancer models and seeks to address challenges for the therapeutic application of NKT cell stimulation for cancer immunotherapy. We believe our multiple platform technologies position us well for continued pipeline expansion and partnership opportunities going forward.

Pepinemab

Pepinemab is a humanized monoclonal antibody that binds and blocks the signaling activity of SEMA4D. We are advancing pepinemab with what we believe to be novel mechanisms of action for the treatment of cancer and certain neurodegenerative diseases, including Huntington’s disease.

Cancer – NSCLC, Osteosarcoma and Melanoma

Pepinemab is currently being studied as a treatment for advanced solid tumors, including NSCLC, osteosarcoma, and melanoma. We have demonstrated in preclinical tumor models that SEMA4D regulates infiltration of immune precursor cells into tumor tissue. Our preclinical data suggest that blocking SEMA4D promotes infiltration of immune cells that can eradicate the tumor. We have also demonstrated in preclinical models the potential for synergy between pepinemab and a checkpoint inhibitor when used in combination. We completed a Phase 1 clinical trial of pepinemab as a single-agent cancer therapy and released top-line data in October 2014. Pepinemab was well tolerated in this clinical trial. In October 2017 in collaboration with Merck KGaA, we initiated the CLASSICAL–Lung clinical trial, a Phase 1b/2 clinical trial of pepinemab in combination with avelumab, an inhibitor of the PD-1/PD-L1 checkpoint pathway, in patients with NSCLC who have not previously been treated with immunotherapy. In July 2018, an additional cohort was added to the CLASSICAL – Lung study to include patients who failed prior immunotherapy. The CLASSICAL-Lung clinical trial has completed enrollment. We anticipate topline data for this trial in the first half of 2020. In February 2018, The Children’s Oncology Group with financial support of the National Cancer Institute, initiated a Phase 1/2 clinical trial of pepinemab as a single agent in pediatric patients with recurrent, relapsed, or refractory solid tumors,

including osteosarcoma. In June 2018, a Phase 1 IST of pepinemab in combination with Yervoy® or with Opdivo® began at the UCLA Jonsson Comprehensive Cancer Center in patients with advanced melanoma who have progressed on prior anti-PD-1/PD-L1 based therapies.

Huntington’s Disease

We are studying pepinemab as a treatment for Huntington’s disease, which is a neurodegenerative genetic disorder that typically manifests in mid-adult life. Our study of pepinemab in Huntington’s disease is based on our prior research of neurodegenerative disease mechanisms, where we demonstrated in preclinical models that SEMA4D triggers activation of both microglia and astrocytes, the innate inflammatory cells of the central nervous system. The chronic activation of microglia and astrocytes has been implicated as an important disease mechanism in Huntington’s disease, progressive MS, and other neurodegenerative disorders. We initiated the SIGNAL study, a Phase 2 clinical trial, in July 2015 in early manifest and late prodromal Huntington’s disease patients. This clinical trial builds upon preclinical studies in an animal model of Huntington’s disease and safety data from a Phase 1 dose-escalation clinical trial of pepinemab in MS patients that we completed in November 2014. We anticipate topline data from the SIGNAL trial in the second half of 2020. The U.S. Food and Drug Administration, or the FDA, has granted both Orphan Drug designation and Fast Track designation to pepinemab for Huntington’s disease.

RISK FACTORS

Investing in our common stock involves a high degree of risk. The prospectus supplement applicable to each offering of our common stock will contain a discussion of the risks applicable to an investment in our common stock. You should carefully consider and evaluate all of the information contained in this prospectus, the applicable prospectus supplement and any related free writing prospectus, as well as any documents incorporated by reference, before you decide to purchase our common stock. In particular, you should carefully consider and evaluate the risks and uncertainties described in “Part I – Item 1A. Risk Factors” of our most recent Annual Report on Form 10-K, as updated by the additional risks and uncertainties set forth or incorporated by reference herein. Additional risks and uncertainties that we are unaware of or that we believe are not material at this time could also materially adversely affect our business, financial condition or results of operations. Any of these risks and uncertainties could materially and adversely affect our business, results of operations and financial condition, which in turn could materially and adversely affect the trading price or value of our common stock. As a result, you could lose all or part of your investment.

This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus. See “Special Note Regarding Forward-Looking Statements” for information relating to these forward-looking statements.

Our amended and restated certificate of incorporation contains exclusive forum provisions, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws or any action asserting a claim that is governed by the internal affairs doctrine.

In addition, our amended and restated certificate of incorporation provides that, unless we consent in writing to an alternative forum, the federal courts of the United States will, to the fullest extent permitted by law, be the sole and exclusive forum for any claim arising under the Securities Act of 1933, as amended, or the Securities Act. However, as previously disclosed in our Current Report on Form 8-K filed on March 4, 2019, in light of the Court of Chancery’s opinion in Sciabacucchi v. Salzberg, C.A. No. 2017-0931-JTL, invalidating provisions in the certificates of incorporation of Delaware companies that purport to limit to federal court the forum in which a stockholder could bring a claim under the Securities Act unless and until the Court of Chancery’s decision is reversed by the Delaware Supreme Court on appeal or otherwise abrogated, we do not intend to enforce this provision of our amended and restated certificate of incorporation. If the Delaware Supreme Court affirms the Court of Chancery’s decision or otherwise makes a determination that provisions such as these are invalid, then we will seek approval by our stockholders to amend our amended and restated certificate of incorporation at our next regularly scheduled annual meeting of stockholders to remove the provision. As a result of the Court of Chancery’s decision or a decision by the Supreme Court of Delaware affirming the Court of Chancery’s decision, we may incur additional costs associated with this provision, which could have an adverse effect on our business, financial condition or results of operations.

For the avoidance of doubt, the exclusive forum provisions described above do not apply to any claims arising under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder.

Table of Contents

These choice of forum provisions may limit our stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our stockholders. The applicable courts may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. With respect to the provision making the Court of Chancery the sole and exclusive forum for certain types of actions, stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. Finally, if a court were to find these provisions of our amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could have a material adverse effect on our business, financial condition or results of operations.

PLAN OF DISTRIBUTION

We may sell the securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through underwriters or dealers, through agents, or directly to one or more purchasers. We may distribute securities from time to time in one or more transactions:

 

   

at a fixed price or prices, which may be changed;

 

   

at market prices prevailing at the time of sale;

 

   

at prices related to such prevailing market prices; or

 

   

at negotiated prices.

We may also sell the securities covered by this registration statement in an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act. Such offering may be made into an existing trading market for such securities in transactions at other than a fixed price on or through the facilities of the Nasdaq Capital Market or any other securities exchange or quotation or trading service on which such securities may be listed, quoted or traded at the time of sale. Such at the market offerings, if any, may be conducted by underwriters acting as principal or agent.

A prospectus supplement or supplements (and any related free writing prospectus that we may authorize to be provided to you) will describe the terms of the offering of the securities, including, to the extent applicable:

 

   

the name or names of any underwriters, dealers or agents, if any;

 

   

the purchase price of the securities and the proceeds we will receive from the sale;

 

   

any over-allotment options under which underwriters may purchase additional securities from us;

 

   

any agency fees or underwriting discounts and other items constituting agents’ or underwriters’ compensation;

 

   

any public offering price;

 

   

any discounts or concessions allowed or reallowed or paid to dealers; and

 

   

any securities exchange or market on which the securities may be listed.

Only underwriters named in the prospectus supplement are underwriters of the securities offered by the prospectus supplement.

If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement, other than securities covered by any overallotment or other option. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities, and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.

Table of Contents

We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

We may provide agents and underwriters with indemnification against civil liabilities related to this offering, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. These transactions may be effected on any exchange or over-the-counter market or otherwise.

Any underwriters or agents who are qualified market makers on the Nasdaq Capital Market may engage in passive market making transactions in the securities on the Nasdaq Capital Market in accordance with Rule 103 of Regulation M under the Exchange Act, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain 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.

In compliance with guidelines of the Financial Industry Regulatory Authority, or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.
