PROSPECTUS SUMMARY
This summary highlights information contained elsewhere in this prospectus and does not contain all of the information you should consider in making your investment decision. Before deciding to invest in our common stock, you should read this entire prospectus carefully, including the sections of this prospectus entitled “Risk Factors” and our consolidated financial statements and related notes incorporated by reference in this prospectus. Unless the context otherwise requires, the words “VistaGen Therapeutics, Inc.” “VistaGen,” “we,” “the Company,” “us” and “our” refer to VistaGen Therapeutics, Inc., a Nevada corporation. “VistaStem Therapeutics, Inc.” and “VistaGen California” refer to our wholly owned subsidiary, VistaGen Therapeutics, Inc., a California corporation doing business as VistaStem Therapeutics, Inc.
Business Overview
We are a multi-asset, clinical-stage biopharmaceutical company committed to developing differentiated new generation medications for anxiety, depression and other central nervous system (CNS) diseases and disorders with high unmet need. Our pipeline includes three clinical-stage CNS drug candidates, each with a differentiated mechanism of action, an exceptional safety profile in all clinical studies to date, and therapeutic potential in multiple CNS markets. We aim to become a fully-integrated biopharmaceutical company that develops and commercializes innovative CNS therapies for large and growing mental health and neurology markets where current treatments are inadequate to meet the needs of millions of patients and caregivers worldwide.
PH94B Neuroactive Nasal Spray for Anxiety-related Disorders
PH94B neuroactive nasal spray is an odorless, first-in-class, fast-acting synthetic neurosteroid with therapeutic potential in a wide range of neuropsychiatric indications involving anxiety or phobia. Conveniently self-administered in microgram doses without systemic exposure, we are initially developing PH94B as a potential fast-acting, non-sedating, non-addictive new generation treatment of social anxiety disorder (SAD). SAD affects over 20 million Americans and, according to the National Institutes of Health (NIH), is the third most common psychiatric condition after depression and substance abuse. A person with SAD feels symptoms of anxiety or fear in certain social situations, such as meeting new people, dating, being on a job interview, answering a question in class, or having to talk to a cashier in a store. Doing everyday things in front of people - such as eating or drinking in front of others or using a public restroom - also causes anxiety or fear. A person with SAD is afraid that he or she will be humiliated, judged, and rejected.  The fear that people with SAD have in social situations is so strong that they feel it is beyond their ability to control. As a result, SAD gets in the way of going to work, attending school, or doing everyday things in situations with potential for interpersonal interaction. People with SAD may worry about these and other things for weeks before they happen. Sometimes, they end up staying away from places or events where they think they might have to do something that will embarrass or humiliate them.  Some people with SAD have performance anxiety. They feel physical symptoms of fear and anxiety in performance situations, such as giving a lecture, a speech or a presentation at school or work, as well as playing a sports game, or dancing or playing a musical instrument on stage.  Without treatment, SAD can last for many years or a lifetime and prevent a person from reaching his or her full potential.
Only three drugs, all oral antidepressants (ADs), are approved by the U.S Food and Drug Administration (FDA) specifically for treatment of SAD. These FDA-approved chronic ADs have slow onset of therapeutic effect (often taking many weeks to months) and significant side effects (often beginning soon after administration). Slow onset of effect, chronic administration and significant side effects may make the FDA-approved ADs inadequate or inappropriate treatment alternatives for many individuals affected by SAD episodically. VistaGen’s PH94B is fundamentally differentiated from all current anxiolytics, including all ADs approved by the FDA for treatment of SAD. Intranasal self-administration of only approximately 3.2 micrograms of PH94B binds to nasal chemosensory receptors that, in turn, activate key neural circuits in the brain that lead to rapid suppression of fear and anxiety. In Phase 2 and pilot Phase 3 clinical studies to date, PH94B has not shown psychological side effects (such as dissociation or hallucinations), systemic exposure, sedation or other side effects and safety concerns that may be caused by the current ADs approved by the FDA for treatment of SAD, as well as by benzodiazepines and beta blockers, which are not approved by the FDA to treat SAD but which may be prescribed by psychiatrists and physicians for treatment of SAD on an off-label basis.

TableABOUT THISPROSPECTUS

This prospectus is part of Contents

In a peer-reviewed, published double-blind, placebo-controlled Phase 2 clinical trial, PH94B neuroactive nasal spray was significantly more effective than placebo in reducing both public-speaking (performance) anxiety (p=0.002) and social interaction anxiety (p=0.009) in laboratory challenges of individuals with SAD within 15 minutes of self-administration of a non-systemic 1.6 microgram dose of PH94B.  Based on its novel mechanism of pharmacological action, rapid-onset of therapeutic effects and exceptional safety and tolerability profile in Phase 2 and pilot Phase 3 clinical trials to date, we are preparing for Phase 3 clinical development of PH94B for treatment of SAD in adults. Our goal is to develop and commercialize PH94B as the first FDA-approved, fast-acting, on-demand, at-home treatment for SAD. Additional potential anxiety-related neuropsychiatric indications for PH94B include general anxiety disorder, peripartum anxiety (pre- and post-partum anxiety), preoperative or pre-testing (e.g., pre-MRI) anxiety, panic disorder, post-traumatic stress disorder and specific social phobias.The FDA has granted Fast Track designation for development of our PH94B neuroactive nasal spray for on-demand treatment of SAD, the FDA’s first such designation for a drug candidate for SAD.
In addition to development of PH94B as a potential treatment for SAD, we announced plans in April 2020 to expand clinical development of PH94B to include treatment of adjustment disorder, an emotional or behavioral reaction considered excessive or out of proportion to a stressful event or major life change, occurring within three months of the stressor, and/or significantly impairing a person’s social, occupational and/or other important areas of functioning. We plan to submit our proposed protocol for an exploratory Phase 2a study of PH94B for treatment of adjustment disorder due to stressors related to the COVID-19 pandemic to the FDA through the Coronavirus Treatment Acceleration Program (CTAP). The proposed Phase 2 study will be conducted in New York City on an open-label basis and involve approximately 30 subjects suffering from adjustment disorder with anxiety from stressors related to the pandemic.
PH10 Neuroactive Nasal Spray for Depression and Suicidal Ideation
PH10 neuroactive nasal spray is an odorless, first-in-class, fast-acting synthetic neurosteroid with therapeutic potential in a wide range of neuropsychiatric indications involving depression and suicidal ideation. Conveniently self-administered in microgram doses without systemic exposure, we are initially developing PH94B as a potential fast-acting, non-sedating, non-addictive new generation treatment of major depressive disorder (MDD).
Depression is a serious medical illness and a global public health concern that can occur at any time over a person's life. While most people will experience depressed mood at some point during their lifetime, MDD is different. MDD is the chronic, pervasive feeling of utter unhappiness and suffering, which impairs daily functioning. Symptoms of MDD include diminished pleasure or loss of interest in activities, changes in appetite that result in weight changes, insomnia or oversleeping, psychomotor agitation, loss of energy or increased fatigue, feelings of worthlessness or inappropriate guilt, difficulty thinking, concentrating or making decisions, and thoughts of death or suicide and attempts at suicide. Current FDA-approved medications available in the multi-billion-dollar global AD market often fall far short of satisfying the unmet medical needs of millions suffering from the debilitating effects of depression.  
While current FDA-approved ADs are widely used, about two-thirds of patients with MDD do not respond to their initial AD treatment. Inadequate response to current ADs is among the key reasons MDD is one of the leading public health concerns in the United States, creating a significant unmet medical need for new agents with fundamentally different mechanisms of action and side effect and safety profiles.
PH10 is a new generation antidepressant with a mechanism of action that is fundamentally different from all current ADs. After self-administration, a non-systemic microgram-level dose of PH10 binds to nasal chemosensory receptors that, in turn, activate key neural circuits in the brain that can lead to rapid-onset antidepressant effects, but without the psychological side effects (such as dissociation and hallucinations) or safety concerns that maybe be caused by ketamine-based therapy (KBT), including intravenous ketamine or esketamine nasal spray, or the significant side effects of current ADs. In an exploratory 30-patient Phase 2a clinical trial, PH10, self-administered at a dose of 6.4 micrograms, was well-tolerated and demonstrated significant (p=0.022) rapid-onset antidepressant effects, which were sustained over an 8-week period, as measured by the Hamilton Depression Rating Scale (HAM-D), without side effects or safety concerns that may be caused by KBT. Based on positive results from this exploratory Phase 2a study, we are preparing for Phase 2b clinical development of PH10 in MDD. With its exceptional safety profile during clinical development to date, we believe PH10, as a convenient at-home therapy, has potential for multiple applications in global depression markets, including as a stand-alone front-line therapy for MDD, as an add-on therapy to augment current FDA-approved ADs for patients with MDD who have an inadequate response to standard ADs, and to prevent relapse following successful treatment with KBT.

AV-101, an Oral NMDA Receptor Antagonist
AV-101 (4-Cl-KYN) targets the NMDAR (N-methyl-D-aspartate receptor), an ionotropic glutamate receptor in the brain. Abnormal NMDAR function is associated with numerous CNS diseases and disorders. AV-101 is an oral prodrug of 7-chloro-kynurenic acid (7-Cl-KYNA), which is a potent and selective full antagonist of the glycine co-agonist site of the NMDAR that inhibits the function of the NMDAR. Unlike ketamine and many other NMDAR antagonists, 7-Cl-KYNA is not an ion channel blocker. In all studies to date, AV-101 has exhibited no dissociative or hallucinogenic psychological side effects or safety concerns similar to those that may be caused by amantadine and KBT. With its exceptionally few side effects and excellent safety profile, AV-101 has potential to be a differentiated oral, new generation treatment for multiple large-market CNS indications where current treatments are inadequate to meet high unmet patient needs. The FDA has granted Fast Track designation for development of AV-101 as both a potential adjunctive treatment for MDD and as a non-opioid treatment for neuropathic pain.
We recently completed a double-blind, placebo-controlled, multi-center Phase 2 clinical trial of AV-101 as a potential adjunctive treatment, together with a standard FDA-approved oral AD (either a selective serotonin reuptake inhibitor (SSRI) or a serotonin norepinephrine reuptake inhibitor (SNRI)), in MDD patients who had an inadequate response to a stable dose of a standard AD (the Elevate Study). Topline results of the Elevate Study (n=199) indicated that the AV-101 treatment arm (1440 mg) did not differentiate from placebo on the primary endpoint (change in the Montgomery-Åsberg Depression Rating Scale (MADRS-10) total score compared to baseline), potentially due to sub-therapeutic levels of 7-Cl-KYNA in the brain. As in prior clinical studies, AV-101 was well tolerated, with no psychotomimetic side effects or drug-related serious adverse events.
Recent discoveries from successful AV-101 preclinical studies suggest that there is a substantially increased brain concentration of AV-101 and its active metabolite, 7-Cl-KYNA, when AV-101 is given together with probenecid, a safe and well-known oral anion transport inhibitor used to treat gout. These surprising effects were first revealed in our recent preclinical studies, although they are consistent with well-documented clinical studies of probenecid increasing the therapeutic benefits of several unrelated classes of approved drugs, including certain antibacterial, anticancer and antiviral drugs. When probenecid was administered adjunctively with AV-101 in an animal model, substantially increased brain concentrations of both AV-101 (7-fold) and of 7-Cl-KYNA (35-fold) were discovered.We also recently identified that some of the same kidney transporters that reduce drug concentrations in the blood, by excretion in the urine, are also found in the blood brain barrier and function to reduce 7-Cl-KYNA levels in the brain by pumping it out of the brain and back into the blood. In the recent preclinical studies with AV-101 and probenecid, we discovered that blocking those transporters in the blood brain barrier with probenecid resulted, as noted above, in a substantially increased brain concentration of 7-Cl-KYNA. This 7-Cl-KYNA efflux-blocking effect of probenecid, with the resulting increased brain levels and duration of 7-Cl-KYNA, suggests the potential impact of AV-101 with probenecid could result in far more profound therapeutic benefits for patients with MDD and other NMDAR-focused CNS diseases and disorders than demonstrated in the Elevate Study. Some of the new discoveries from our recent AV-101 preclinical studies with adjunctive probenecid were presented by a collaborator of VistaGen at the British Pharmacological Society’s Pharmacology 2019 annual conference in Edinburgh, UK in December 2019.


-3-
In addition, a Phase 1b target engagement study completed after the Elevate Study by the Baylor College of Medicine (Baylor) with financial support from the U.S. Department of Veterans Affairs (VA), involved 10 healthy volunteer U.S. military Veterans who received single doses of AV-101 (720 mg or 1440 mg) or placebo, in a double-blind, randomized, cross-over controlled trial. The primary goal of the study was to identify and define a dose-response relationship between AV-101 and multiple electrophysiological (EEG) biomarkers related to NMDAR function, as well as blood biomarkers associated with suicidality (theBaylor Study). The findings from the Baylor Study suggest that, in healthy Veterans, the higher dose of AV-101 (1440 mg) was associated with dose-related increase in the 40 Hz Auditory Steady State Response (ASSR), a robust measure of the integrity of inhibitory interneuron synchronization that is associated with NMDAR inhibition. Findings from the successful Baylor Study were presented at the 58th Annual Meeting of the American College of Neuropsychopharmacology (ACNP) in Orlando, Florida in December 2019.
The successful Baylor Study and the recent discoveries in our preclinical studies involving AV-101 and adjunctive probenecid suggest that it may be possible to increase therapeutic concentrations and duration of 7-Cl-KYNA in the brain, and thus increase NMDAR antagonism in MDD patients with an inadequate response to standard ADs when AV-101 and probenecid are combined. During 2020, we plan to conduct additional AV-101 preclinical studies with adjunctive probenecid to evaluate its potential applicability to MDD, suicidal ideation and other NMDAR-focused CNS indications for which we have existing preclinical data with AV-101 as a monotherapy, including epilepsy, levodopa-induced dyskinesia, and neuropathic pain, to determine the most appropriate path forward for potential future clinical development and commercialization of AV-101.
VistaStem Therapeutics – Stem Cell Technology for Drug Rescue and Regenerative Medicine
In addition to our current CNS drug candidates, we have stem cell technology-based, pipeline-enabling programs through our wholly-owned subsidiary, VistaStem Therapeutics (VistaStem). VistaStem is focused on applying human pluripotent stem cell (hPSC) technologies, including our customized cardiac bioassay system,CardioSafe 3D, to discover and develop small molecule New Chemical Entities (NCEs) for our CNS pipeline or out-licensing. In addition, VistaStem’s stem cell technologies involving hPSC-derived blood, cartilage, heart and liver cells have multiple potential applications in the cell therapy (CT) and regenerative medicine (RM) fields.
To advance potential CT and RM applications of VistaStem’s hPSC technologies related to heart cells, we licensed to BlueRock Therapeutics LP, a next generation CT/RM company formed jointly by Bayer AG and Versant Ventures, rights to develop and commercialize certain proprietary technologies relating to the production of cardiac stem cells for the treatment of heart disease. As a result of its acquisition of BlueRock Therapeutics in 2019, Bayer AG now holds rights to develop and commercialize VistaStem’s hPSC technologies relating to the production of heart cells for the treatment of heart disease (the Bayer Agreement).  In a manner similar to the Bayer Agreement, we may pursue additional collaborations involving rights to develop and commercialize VistaStem’s hPSC technologies for production of blood, cartilage, and/or liver cells for CT and RM applications, including, among other indications, treatment of arthritis, cancer and liver disease.

Risks Related to this Offering
Our stock price may be volatile, and you may not be able to resell shares of our common stock at or above the price you paid.
The public trading price for our common stock can be affected by a number of factors, including:
● 
plans for, progress of or results from nonclinical and clinical development activities related to our product candidates;
●            
the failure of the FDA or other regulatory authority to approve our product candidates;
● 
announcements of new products, technologies, commercial relationships, acquisitions or other events by us or our competitors;
●            
the success or failure of other CNS therapies;
●            
regulatory or legal developments in the U.S. and other countries;
●            
announcements regarding our intellectual property portfolio;
●            
failure of our product candidates, if approved, to achieve commercial success;
●            
fluctuations in stock market prices and trading volumes of similar companies;
●            
variations in our quarterly operating results;
●            
changes in our financial guidance or securities analysts’ estimates of our financial performance;
● 
sales or purchases of large blocks of our common stock, including sales or purchases by our executive officers, directors and significant stockholders;
●            
establishment of short positions by holders or non-holders of our stock;
●            
additions or departures of key personnel;
●            
discussion of us or our stock price by the press and by online investor communities; and
● 
general market conditions and overall fluctuations in U.S. equity markets, including fluctuations attributable to the recent outbreak of the novel coronavirus (COVID-19);
● 
conditions that are outside of our control, such as the impact of health and safety concerns from the current outbreak of COVID-19 or other unforeseeable circumstances; and
● 
other risks and uncertainties described in these risk factors and the risk factors incorporated into this prospectus by reference.
In recent years, the stock markets generally and the stock prices of many companies in the pharmaceutical industry have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry factors may significantly affect the market price of our common stock, regardless of our actual operating performance. These fluctuations may be even more pronounced in the trading market for our common stock shortly following this offering. If the market price of shares of our common stock does not ever exceed the price at which shares are acquired under the Purchase Agreement, you may not be able to resell shares of our common stock at or above the price you paid.
Future sales and issuances of our common stock or other securities may result in significant dilution and could cause the price of our common stock to decline.
To raise capital, we may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. These sales may also result in material dilution to our existing stockholders, and new investors could gain rights superior to our existing stockholders.
In addition, sales of a substantial number of shares of our outstanding common stock in the public market could occur at any time. Certain of our stockholders, including certain of the selling stockholders, hold a substantial number of our common stock that many of them are now able to sell in the public market. Sales of stock by these stockholders could have a material adverse effect on the trading price of our common stock.
We cannot predict what effect, if any, sales of our shares in the public market or the availability of shares for sale will have on the market price of our common stock. However, future sales of substantial amounts of our common stock in the public market, including shares issued upon exercise of outstanding warrants or options, or the perception that such sales may occur, could adversely affect the market price of our common stock.

USE OF PROCEEDS
The common stock to be offered and sold using this prospectus will be offered and sold by the selling stockholders named in this prospectus. Accordingly, we will not receive any proceeds from any sale of shares of our common stock in this offering. All shares of common stock registered by this prospectus may be issued upon exercise of the Warrants. Upon any exercise of the Warrants, the selling stockholders will pay us the applicable exercise price, and we currently anticipate that any such proceeds would be used primarily for working capital and general corporate purposes. We will pay all of the fees and expenses incurred by us in connection with this registration. We will not be responsible for fees and expenses incurred by the selling stockholders or any underwriting discounts or agent’s commissions.
-13-
DIVIDEND POLICY
We have never paid or declared any cash dividends on our common stock, and we do not anticipate paying any cash dividends on our common stock in the foreseeable future.   Shares of our Series B 10% Convertible Preferred Stock accrue dividends at a rate of 10% per annum, which dividends are payable solely in unregistered shares of our common stock at the time the Series B 10% Convertible Preferred Stock is converted into common stock.
-14-
PLAN OFDISTRIBUTION
We are registering the Shares and shares of common stock issuable upon exercise of the Warrants held by the selling stockholders identified herein to permit the resale of these shares of common stock by the holders thereof from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of our common stock, if any. We will bear all fees and expenses incident to our obligation to register the shares of our common stock.
The common stock may be sold or distributed from time to time by the selling stockholder directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. The sale of the common stock offered by this prospectus could be affected in one or more of the following methods:
ordinary brokers’ transactions;
transactions involving cross or block trades;
through brokers, dealers, or underwriters who may act solely as agents;
“at the market” into an existing market for the common stock;
in other ways not involving market makers or established business markets, including direct sales to purchasers or sales effected through agents;
in privately negotiated transactions; or
any combination of the foregoing.
In order to comply with the securities laws of certain states, if applicable, the shares may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the state or an exemption from the state’s registration or qualification requirement is available and complied with.
If the selling stockholders effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of our common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of common stock short and deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares.
The selling stockholders may pledge or grant a security interest in some or all of the Warrants or shares of common stock owned by them, and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.
The selling stockholders and any broker-dealer participating in the distribution of the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of common stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of common stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.
-15-
Under the securities laws of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.
There can be no assurance that any selling stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement, of which this prospectus forms a part.
The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of common stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.
We will pay all expenses of the registration of the shares of common stock pursuant to the Registration Rights Agreement, including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws;provided, however,that a selling stockholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act, in accordance with the Registration Rights Agreements, or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the related Registration Rights Agreement, or we may be entitled to contribution.
Once sold under the registration statement, of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands of persons other than our affiliates.

Our Compensation Objectives
Our compensation practices are designed to attract key employees and to retain, motivate and reward our executive officers for their performance and contribution to our long-term success. Our Board, through the Compensation Committee, seeks to compensate our executive officers by combining short and long-term cash and equity incentives. It also seeks to reward the achievement of corporate and individual performance objectives, and to align executive officers’ incentives with stockholder value creation. When possible, the Compensation Committee seeks to tie individual goals to the area of the executive officer’s primary responsibility. These goals may include the achievement of specific financial or business development goals. Also, when possible and appropriate taking into account the Company’s financial condition and other related facts and circumstances, the compensation committee seeks to set performance goals that reach across all business areas and include achievements in finance/business development and corporate development.
The Compensation Committee makes decisions regarding salaries, annual bonuses, if any, and equity incentive compensation for our executive officers, approves corporate goals and objectives relevant to the compensation of the Chief Executive Officertrademarks and our other executive officers. The Compensation Committee solicits input from our Chief Executive Officer regarding the performance of our other executive officers. Finally, the Compensation Committee also administers our incentive compensation and benefit plans.
Although we have no formal policy for a specific allocation between current and long-term compensation, or cash and non-cash compensation, when possible and appropriate taking into account the Company’s financial condition and other related facts and circumstances, we seek to implement a pay mix for our officers with a relatively equal balance of both, providing a competitive salary with a significant portion of compensation awarded on both corporate and personal performance.
-20-
Compensation Components
As a general rule, and when possible and appropriate taking into account the Company’s financial condition and other related facts and circumstances, our compensation consists primarily of three elements: base salary, annual bonus and long-term equity incentives. We describe each element of compensation in more detail below.
Base Salary
Base salaries for our executive officers are established based on the scope of their responsibilities and their prior relevant experience, taking into account competitive market compensation paid by other companies in our industry for similar positions and the overall market demand for such executives, both initially at the time of hire and thereafter, to ensure that we retain our executive management team. An executive officer’s base salary is also determined by reviewing the executive officer’s other compensation to ensure that the executive officer’s total compensation is in line with our overall compensation philosophy.
Base salaries are reviewed periodically as deemed necessary by the Compensation Committee and increased for merit reasons, based on the executive officers’ success in meeting or exceeding individual objectives. Additionally, we may adjust base salaries as warranted throughout the year for promotions or other changes in the scope or breadth of an executive officer’s role or responsibilities.
Annual Bonus
The Compensation Committee assesses the level of the executive officer’s achievement of meeting individual goals, as well as that executive officer’s contribution towards our corporate-wide goals. The amount of the cash bonus depends on the level of achievement of the individual performance goals, with a target bonus generally set as a percentage of base salary and based on the achievement of pre-determined milestones.  For the year ended March 31, 2019, each Named Executive Officer (NEO) serving during that period was awarded a bonus by the Compensation Committee in the amount set forth in the Summary Compensation Table below. The Compensation Committee has not yet determined or awarded a bonus to any NEO for our fiscal year ended March 31, 2020. Payment of a bonus to an NEO for our fiscal year ended March 31, 2020, if any, is at the discretion of the Compensation Committee which may consider factors other than attainment of individual or corporate goals in its determination of bonus amounts to be granted.
Long-Term Equity Incentives
The Compensation Committee believes that to attract and retain management, employees and independent directors, the compensation paid to these persons should include non-cash equity-based compensation, in addition to base salary and potential annual cash incentives, that is competitive with peer companies. The Compensation Committee determines the amount and terms of non-cash equity-based compensation granted under our stock option plans or pursuant to other awards made to our executives, employees and independent directors. Any long-term equity compensation granted to our management, employees and independent directors does not represent cash payments made to such individuals, and there is no guarantee that any recipients of awards granted as long-term equity compensation will realize any cash value as a result of the awards.
During the year ended March 31, 2020, the Compensation Committee granted stock options to management, employees and independent directors as a part of each individual's long-term compensation. The options have a term of ten years, and an exercise price that was at or above the market price of our common stock on the grant date, which the Compensation Committee believes align the long-term interests of our management, employees and independent directors with those of our stockholders. In addition, the exercise price of the options granted during our 2020 fiscal year remains above the market price of our common stock as of March 31, 2020.

Benefit Plans
401(k) Plan
We maintain, through a registered agent, a retirement and deferred savings plan for our officers and employees. This plan is intended to qualify as a tax-qualified plan under Section 401(k) of the Internal Revenue Code of 1986, as amended. The retirement and deferred savings plan provides that each participant may contribute a portion of his or her pre-tax compensation, subject to statutory limits. Under the plan, each employee is fully vested in his or her deferred salary contributions. Employee contributions are held and invested by the plan’s trustee. The retirement and deferred savings plan also permits us to make discretionary contributions subject to established limits and a vesting schedule.  To date, we have not made any discretionary contributions to the retirement and deferred savings plan on behalf of participating employees.
2019 Employee Stock Purchase Plan
Following the approval of our 2019 Employee Stock Purchase Plan (the 2019 ESPP) by our stockholders in September 2019, the 2019 ESPP became operational effective January 1, 2020. Under our 2019 ESPP, shares of our common stock will be available for purchase by eligible employees, including our NEO’s, who participate in the plan. Eligible employees will be entitled to purchase, by means of payroll deductions, limited amounts of our common stock at a discount to the market price during periodic option periods under the 2019 ESPP. At March 31, 2020, no option period had been completed under the 2019 ESPP.

Employment or Severance Agreements
We have employment agreements with Mr. Singh and Dr. Snodgrass, the material terms of which are described below.
Singh Agreement
We entered into an employment agreement with Mr. Singh on April 28, 2010. Under the agreement, as amended on June 22, 2016, Mr. Singh’s base salary was increased from $347,500 per year to $395,000 per year, effective June 16, 2016. The Compensation Committee has subsequently adjusted Mr. Singh’s base annual salary to $477,000 effective in July 2018 and to $498,000 effective in April 2019. Under his agreement, Mr. Singh is eligible to receive an annual incentive cash bonus of up to 50% of his base salary. The Compensation Committee awarded Mr. Singh a cash bonus of $110,305 for attainment of performance-based objectives during the year ended March 31, 2019. The Compensation Committee has not yet determined or awarded a bonus to Mr. Singh for attainment of performance-based objectives during our fiscal year ended March 31, 2020. The award of his annual incentive bonus is at the discretion of the Compensation Committee of our Board of Directors. In the event we terminate Mr. Singh’s employment without cause, he is entitled to receive severance in an amount equal to:
twelve months of his then-current base salary payable in the form of salary continuation;
a pro-rated portion of the incentive cash bonus that the Board of Directors determines in good faith that Mr. Singh earned prior to his termination; and
such amounts required to reimburse him for Consolidated Omnibus Budget Reconciliation Act (COBRA) payments for continuation of his medical health benefits for such twelve-month period.
In addition, in the event Mr. Singh terminates his employment with “good reason” following a “change of control” (each as defined below), he is entitled to twelve months of his then-current base salary payable in the form of salary continuation.
Snodgrass Agreement
We entered into an employment agreement with Dr. Snodgrass on April 28, 2010. Under the agreement, as amended on June 22, 2016, Dr. Snodgrass’s base salary was increased from $305,000 per year to $350,000 per year, effective June 16, 2016. The Compensation Committee has subsequently adjusted Dr. Snodgrass’ base annual salary to $397,000 effective in July 2018 and to $416,850 effective in April 2019. Under his agreement, Dr. Snodgrass is eligible to receive an annual incentive cash bonus of up to 50% of his base salary. The Compensation Committee awarded Dr. Snodgrass cash bonuses of $73,444 for attainment of performance-based objectives during the year ended March 31, 2019. The Compensation Committee has not yet determined or awarded a bonus to Dr. Snodgrass for attainment of performance-based objectives during our fiscal year ended March 31, 2020. The award of his annual incentive bonus is at the discretion of the Compensation Committee of the Board of Directors. In the event we terminate Dr. Snodgrass’s employment without cause, he is entitled to receive severance in an amount equal to:
twelve months of his then-current base salary payable in the form of salary continuation;
a pro-rated portion of the incentive bonus that the Board of Directors determines in good faith that Dr. Snodgrass earned prior to his termination; and
such amounts required to reimburse him for COBRA payments for continuation of his medical health benefits for such twelve-month period.
In addition, in the event Dr. Snodgrass terminates his employment with "good reason" (as defined below), he is entitled to twelve months of his then-current base salary payable in the form of salary continuation.
-28-
Change of Control Provisions
Pursuant to each of their respective employment agreements, Dr. Snodgrass is entitled to severance if he terminates his employment at any time for “good reason” (as defined below), while Mr. Singh is entitled to severance if he terminates his employment for good reason after a change of control. Under their respective agreements, “good reason” means any of the following events, if we affect the event without the executive’s consent (subject to our right to cure):
a material reduction in the executive’s responsibility; or
a material reduction in the executive’s base salary except for reductions that are comparable to reductions generally applicable to similarly situated executives of VistaGen.
Furthermore, pursuant to their respective employment agreements and their stock option award agreements, as amended, in the event we terminate the executive without cause within twelve months of a change of control, the executive’s remaining unvested option shares become fully vested and exercisable. Upon a change of control in which the successor corporation does not assume the executive’s stock options, the stock options granted to the executive become fully vested and exercisable.
Pursuant to their respective employment agreements, a change of control occurs when: (i) any “person” as such term is used in Sections 13(d) and 14(d) of the Exchange Act (other than VistaGen, a subsidiary, an affiliate, or a VistaGen employee benefit plan, including any trustee of such plan acting as trustee) becoming the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of VistaGen representing 50% or more of the combined voting power of VistaGen’s then outstanding securities; (ii) a sale of substantially all of VistaGen’s assets; or (iii) any merger or reorganization of VistaGen whether or not another entity is the survivor, pursuant to which the holders of all the shares of capital stock of VistaGen outstanding prior to the transaction hold, as a group, fewer than 50% of the shares of capital stock of VistaGen outstanding after the transaction.
In the event that, following termination of employment, amounts are payable to an executive pursuant to his employment agreement, the executive’s eligibility for severance is conditioned on executive having first signed a release agreement.
Pursuant to their respective employment agreements, the estimated amount that could be paid by us assuming that a change of control occurred on the last business day of our current fiscal year, is $498,000 for Mr. Singh and $416,850 for Dr. Snodgrass, excluding the imputed value of accelerated vesting of incentive stock options, if any.

Director Compensation
We adopted a director compensation policy for the independent directors of our Board, as “independent” is defined by the rules of the Nasdaq Stock Market rules, which policy became effective for our fiscal year beginning April 1, 2014. Under our independent director compensation policy, our independent directors are entitled to receive a $25,000 annual retainer, payable in cash or shares of our common stock. For service on a committee of the Board, an independent director is entitled to receive an additional annual cash retainer of $7,500 for service on our Audit Committee and Compensation Committee, and $5,000 for service on our Corporate Governance and Nominating Committee. In lieu of the annual cash retainer for committee participation, each independent director serving as a chair of a Board committee shall receive an annual cash retainer of $15,000 for the Audit Committee and Compensation Committee chairs and $10,000 for the Corporate Governance and Nominating Committee chair. In addition, each independent director will also receive an annual grant of an option or warrant to purchase a minimum of 12,000 shares of our common stock, which will vest monthly over a one-year period from the date of grant. Prorated grants are made for partial years of service.
We paid our independent directors cash compensation consistent with the policy noted above during our fiscal year ended March 31, 2020.

In May 2019, we granted to each of our four independent directors options to purchase 50,000 shares of our common stock at an exercise price of $1.00 per share under the terms of our Amended and Restated 2016 Stock Incentive Plan (the2016 Plan). In October 2019, following the approval by our stockholders of our 2019 Omnibus Equity Incentive Plan (the2019 Plan), we granted to each of our four independent directors options to purchase 75,000 shares of our common stock at an exercise price of $1.41 per share under the terms of our 2019 Plan. Each grant awarded to our independent directors during the year ended March 31, 2020 expires ten years after the date of grant.

Board Attendance at Board of Directors, Committee and Stockholder Meetings
Our Board met five times and acted by unanimous written consent five times during our fiscal year ended March 31, 2020. Our Audit Committee met four times. Our Compensation Committee met once, acted by unanimous written consent three times with respect to executive compensation matters and grants of equity securities, and requested action by the entire Board with respect to the adoption of our 2019 Omnibus Equity Incentive Plan and 2019 Employee Stock Purchase Plan and the modification of certain outstanding warrants. Our Corporate Governance and Nominating Committee requested action by the entire Board with respect to re-election of members of our Board and other resolutions presented to our stockholders at our September 2019 annual meeting of stockholders and Board committee assignments. With the exception of Dr. Snodgrass, who was unable to attend one Board meeting due to international travel, each director serving during Fiscal 2020 attended all of the meetings of the Board and the committees of the Board upon which such director served that were held during the fiscal year.
We do not have a formal policy regarding attendance by members of the Board at our annual meetings of stockholders, but directors are encouraged to attend. With the exception of Dr. Underdown and Ms. Cunningham, each of whom was unavailable, each of our directors attended our September 2019 Annual Meeting of Stockholders in person.
Independent Directors
Our securities are currently listed on the Nasdaq Capital Market, which requires that a majority of our directors be independent. Accordingly, we evaluate director independence under the standards established by the SEC and the rules of the Nasdaq Stock Market.
Subject to some exceptions, these standards generally provide that a director will not be independent if (a) the director is, or in the past three years has been, an employee of ours; (b) a member of the director’s immediate family is, or in the past three years has been, an executive officer of ours; (c) the director or a member of the director’s immediate family has received more than $200,000 per year in direct compensation from us other than for service as a director (or for a family member, as a non-executive employee); (d) the director or a member of the director’s immediate family is, or in the past three years has been, employed in a professional capacity by our independent public accountants, or has worked for such firm in any capacity on our audit; (e) the director or a member of the director’s immediate family is, or in the past three years has been, employed as an executive officer of a company where one of our executive officers serves on the compensation committee; or (f) the director or a member of the director’s immediate family is an executive officer of a company that makes payments to, or receives payments from, us in an amount which, in any twelve-month period during the past three years, exceeds the greater of $1,000,000 or two percent of that other company’s consolidated gross revenues. 

Our Board has undertaken a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that Mr. Saxe, Dr. Underdown, Dr. Gin and Ms. Cunningham are each “independent” as that term is defined by the rules of the Nasdaq Stock Market. Our Board has also determined that Mr. Saxe, Dr. Underdown and Dr. Gin, who together comprise our Audit Committee and Compensation Committee, and, together with Ms. Cunningham comprise our Corporate Governance and Nominating Committee, satisfy the independence standards set forth in the Nasdaq Stock Market rules. In making these determinations, our Board considered the current and prior relationships that each nonemployee director has with the Company and all other facts and circumstances that our Board deemed relevant.
-33-

Board Committees and Charters
Our Board has established an Audit Committee, a Compensation Committee and a Corporate Governance and Nominating Committee. The composition and responsibilities of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Since April 1, 2017, only our independent directors, Mr. Saxe, Dr. Underdown and Dr. Gin, and, since January 10, 2019, Ms. Cunningham, serve as members of these committees.
The Audit Committee of our Board is comprised of Mr. Saxe, who serves as the committee chairman, Dr. Underdown and Dr. Gin. Mr. Saxe is also our Audit Committee financial expert, as that term is defined under SEC rules implementing Section 407 of the Sarbanes Oxley Act of 2002, and possesses the requisite financial sophistication, as defined under applicable rules. The Audit Committee operates under a written charter. Our Audit Committee charter is available on our website atwww.vistagen.com. Under its charter, our Audit Committee is primarily responsible for, among other things, the following:
overseeing our accounting and financial reporting process;
selecting, retaining and replacing our independent auditors and evaluating their qualifications, independence and performance;
reviewing and approving scope of the annual audit and audit fees;
monitoring rotation of partners of independent auditors on engagement team as required by law;
discussing with management and independent auditors the results of annual audit and review of quarterly financial statements;
reviewing adequacy and effectiveness of internal control policies and procedures;
approving retention of independent auditors to perform any proposed permissible non-audit services;
overseeing internal audit functions and annually reviewing audit committee charter and committee performance; and
preparing the audit committee report that the SEC requires in our annual proxy statement.
-34-
Compensation Committee
The Compensation Committee of our Board is comprised of Dr. Underdown, who serves as the committee chairman, Mr. Saxe, and Dr. Gin. Our Compensation Committee charter is available on our website atwww.vistagen.com. Under its charter, the Compensation Committee is primarily responsible for, among other things, the following:
reviewing and approving our compensation programs and arrangements applicable to our executive officers (as defined in Rule I 6a-I (f) of the Securities Exchange Act of 1934, as amended (theExchange Act)), including all employment-related agreements or arrangements under which compensatory benefits are awarded or paid to, or earned or received by, our executive officers, including, without limitation, employment, severance, change of control and similar agreements or arrangements;
determining the objectives of our executive officer compensation programs;
ensuring corporate performance measures and goals regarding executive officer compensation are set and determining the extent to which they are achieved and any related compensation earned;
establishing goals and objectives relevant to Chief Executive Officer compensation, evaluating Chief Executive Officer performance in light of such goals and objectives, and determining Chief Executive Officer compensation based on the evaluation;
endeavoring to ensure that our executive compensation programs are effective in attracting and retaining key employees and reinforcing business strategies and objectives for enhancing stockholder value, monitoring the administration of incentive-compensation plans and equity-based incentive plans as in effect and as adopted from time to time by the Board;
reviewing and approving any new equity compensation plan or any material change to an existing plan; and
reviewing and approving any stock option award or any other type of award as may be required for complying with any tax, securities, or other regulatory requirement, or otherwise determined to be appropriate or desirable by the committee or Board.
Corporate Governance and Nominating Committee
The Corporate Governance and Nominating Committee of our Board is comprised of Dr. Gin, who serves as the committee chairman, Mr. Saxe, Dr. Underdown and Ms. Cunningham. Our Corporate Governance and Nominating Committee charter is available on our website atwww.vistagen.com. Under its charter, the Corporate Governance and Nominating Committee is primarily responsible for, among other things, the following:
monitoring the size and composition of the Board;
making recommendations to the Board with respect to the nominations or elections of our directors;
reviewing the adequacy of our corporate governance policies and procedures and our Code of Business Conduct and Ethics, and recommending any proposed changes to the Board for approval; and
considering any requests for waivers from our Code of Business Conduct and Ethics and ensure that we disclose such waivers as may be required by the exchange on which we are listed, if any, and rules and regulations of the SEC.
Compensation Committee Interlocks and Insider Participation
The Compensation Committee of our Board consists of Dr. Underdown, Mr. Saxe and Dr. Gin, each of whom is an independent, nonemployee director. None of the members of the Compensation Committee has a relationship that would constitute an interlocking relationship with executive officers or directors of another entity.
-35-
Board Leadership Structure
The Board currently separates the roles of Chief Executive Officer and Chairman of the Board in recognition of the differences between the two roles. Our Chief Executive Officer, who is also a member of our Board, is responsible for setting the strategic direction of the Company and the day-to-day leadership and performance of the Company, while the Chairman of the Board provides guidance to the Chief Executive Officer and sets the agenda for the Board meetings and presides over meetings of the Board. Although these roles are currently separate, the Board believes it should be able to freely select the Chairman of the Board based on criteria that it deems to be in the best interest of the Company and its stockholders, and therefore one person may, in the future, serve as both the Chief Executive Officer and Chairman of the Board.
Board Role in Risk Assessment
Management, in consultation with outside professionals, as applicable, identifies risks associated with the Company’s operations, strategies and financial statements. Risk assessment is also performed through periodic reports received by the Audit Committee from management, counsel and the Company’s independent registered public accountants relating to risk assessment and management. Audit Committee members meet privately in executive sessions with representatives of the Company’s independent registered public accountants. The Board also provides risk oversight through its periodic reviews of the financial and operational performance of the Company.
Code of Ethics
We have adopted a Code of Business Conduct and Ethics applicable to our employees, officers and directors.  Our Code of Business Conduct and Ethics is available on our website atwww.vistagen.com.  We intend to disclose any future amendments to certain provisions of our Code of Business Conduct and Ethics, or waivers of these provisions, on our website or in filings with the SEC under the Exchange Act.

COMPANYOVERVIEW

This summary highlights information contained elsewhere in this prospectus. This summary does not contain all the information you should consider before buying our securities. You should read the following summary together with the more detailed information appearing in this prospectus and any accompanying prospectus supplement, including the section titled Risk Factors on page 3, before deciding whether to purchase our securities.

Overview

We are a clinical-stage biopharmaceutical company pioneering neuroscience to deliver first-in-class therapies for psychiatric and neurological disorders. Five of our six clinical-stage product candidates – fasedienol (PH94B), itruvone (PH10), PH15, PH80 and PH284 – belong to a new class of drugs known as pherines, which have the potential to rapidly deliver meaningful efficacy with a differentiated safety profile. Pherines are investigational neuroactive nasal sprays with innovative proposed mechanisms of action that activate chemosensory neurons in the nasal passages to impact fundamental neural circuits in the brain without the need for systemic absorption or binding to receptors in the brain. Our sixth clinical-stage product candidate, AV-101, is an investigational oral drug candidate with the potential to inhibit, but not block, NMDA receptor activity.

We are passionate about transforming what is possible in the treatment of anxiety, depression, and other neuroscience disorders.

Our Clinical-Stage Neuroscience Product Candidates

Fasedienol Nasal Spray for Social Anxiety Disorder (SAD)

Fasedienol (PH94B) is an odorless, tasteless synthetic investigational pherine nasal spray from the androstane family in Phase 3 clinical development for the acute treatment of anxiety for adults with SAD. When administered intranasally in microgram-level doses, fasedienol activates receptors of peripheral nasal chemosensory neurons connected to subsets of neurons in the olfactory bulbs that, in turn, connect to neurons in the limbic amygdala involved in the pathophysiology of SAD, and potentially other anxiety and mood disorders. Fasedienol is pharmacologically active without requiring apparent systemic absorption or direct activity on neurons in the brain to achieve its rapid-onset and short-duration anxiolytic effects. We believe fasedienol has the potential to achieve these effects with significantly reduced risks of side effects and other safety concerns, such as potential drug-drug interactions, abuse, misuse, and addiction, associated with certain other systemic pharmaceuticals that act directly on neurons in the brain and are sometimes prescribed for anxiety disorders.

The U.S. Food and Drug Administration (the FDA) has granted Fast Track designation for the development of fasedienol as a potential treatment for SAD.

Fasedienol PALISADE Phase 3 Program in SAD

Given how fasedienol’s rapid-onset mechanism of action (MOA) is differentiated from all FDA-approved anxiety drugs, our primary target indication for fasedienol is the acute treatment of anxiety in adults with SAD.  Currently, there is no FDA-approved drug therapy for the acute treatment of SAD.  For that acute indication, we have aligned with the FDA that the Subjective Units of Distress Scale (SUDS) is an appropriate primary efficacy endpoint because it provides a measure of anxiety on a minute-by-minute basis immediately related to the specific stressor. We believe utilizing a simulated anxiety-provoking public speaking challenge study design provides the most appropriate and efficient path for the Phase 3 clinical development of fasedienol’s potential to become the first FDA-approved acute treatment of anxiety for adults with SAD. Our PALISADE Phase 3 Program currently includes four randomized, double-blind, placebo-controlled, Phase 3 clinical trials designed to evaluate the efficacy, safety, and tolerability of a single dose of fasedienol to relieve anxiety symptoms in adult patients with SAD during a simulated, anxiety-provoking public speaking challenge in a clinical setting, as measured using the patient-reported SUDS, two of which Phase 3 trials (PALISADE-1 and PALISADE-2) have been concluded and two of which Phase 3 trials (PALISADE-3 and PALISADE-4) will be initiated in 2024, each with open-label extension. Our PALISADE Phase 3 Program also includes an open-label safety study concluded in 2022 (PALISADE OLS), a Phase 2 repeat dose study to be initiated in 2024 (Repeat Dose Study), two standard preclinical studies to be initiated in 2024, and a small human factor study planned to be initiated in 2025.

In early August 2023, we received and reported positive topline results from our PALISADE-2 Phase 3 trial of fasedienol in SAD based on the 141 subjects who completed the trial. Our PALISADE-2 Phase 3 trial met its primary efficacy endpoint, the difference in mean SUDS scores during the public speaking challenge at baseline (Visit 2) and treatment (Visit 3) for subjects treated with fasedienol versus placebo at Visit 3.  Fasedienol-treated patients demonstrated a greater mean change from baseline (least-squares (LS) mean = -13.8) compared to placebo (LS mean = -8.0), for a statistically significant, and we believe clinically relevant, difference between groups of -5.8 (p=0.015).  The trial also met its secondary endpoint, demonstrating a statistically significant difference in the proportion of clinician-assessed responders between fasedienol and placebo as measured by the Clinical Global Impressions – Improvement (CGI-I) scale.  Responders were identified as those who were rated ‘very much less anxious’ or ‘much less anxious’ and 37.7% of fasedienol-treated patients were rated as responders, as compared to 21.4% of those treated with placebo (p=0.033). The trial also met the important exploratory endpoint of the difference in the proportion of patient-assessed responders between fasedienol and placebo as measured by the Patient’s Global Impression of Change (PGI-C). Responders were identified as those who self-rated ‘very much less anxious’ or ‘much less anxious’ and 40.6% of fasedienol-treated patients were rated as responders, as compared to 18.6% of those treated with placebo (p=0.003). In addition, our PALISADE-2 trial also met the exploratory endpoint of the difference in the proportion of patients in each treatment group with a 20-point or greater improvement in patient-assessed SUDS score from baseline (Visit 2) to treatment (Visit 3). Of the fasedienol-treated patients, 35.7% demonstrated this statistically significant and clinically meaningful improvement in SUDS score, as compared to 18.6% in the placebo-treated group (p=0.020). Fasedienol was observed to be well-tolerated with no serious adverse events, and the treatment-emergent adverse event (TEAE) profiles were comparable between fasedienol and placebo. Overall, no TEAE, except for pyrexia in the placebo group (2.49%), was more prevalent than 2.0%. 

To complement the positive topline results from PALISADE-2, we are preparing to launch PALISADE-3 in the first half of 2024 and PALISADE-4 in the second half of 2024. Like PALISADE-2, both PALISADE-3 and PALISADE-4 will be multi-center, randomized, double-blind, placebo-controlled studies designed to evaluate the efficacy, safety, and tolerability of the acute administration of fasedienol to relieve anxiety symptoms in adult patients with SAD after a single dose of fasedienol during a simulated, anxiety-provoking public speaking challenge in a clinical setting, as measured using the patient-reported SUDS as the primary efficacy endpoint. In addition, both PALISADE-3 and PALISADE-4 will have an open-label extension for a period of up to 12 months. We believe either PALISADE-3 or PALISADE-4, if successful, together with PALISADE-2, may establish substantial evidence of effectiveness of fasedienol in support of a potential fasedienol NDA submission for the acute treatment of anxiety in adults with SAD with the FDA.

We are also planning to initiate the Repeat Dose Study in the second half of 2024. The Repeat Dose Study will be a multi-center, randomized, double-blind, placebo-controlled, clinical trial designed to evaluate repeated dosing of fasedienol in adult patients with SAD during a single simulated, anxiety-provoking public speaking challenge in a clinical setting. The Repeat Dose Study trial will consist of three different dosing arms, with an open-label extension for a period of up to 12 months.

The U.S. FDA has granted Fast Track designation for the investigation of fasedienol for the acute treatment of SAD.

Itruvone Nasal Spray for Major Depressive Disorder (MDD)

Itruvone (PH10) is an odorless, tasteless synthetic investigational neuroactive pherine nasal spray from the pregnane family with an innovative potential MOA that is fundamentally differentiated from the MOA of all currently approved treatments for depression disorders. Itruvone neuroactive nasal spray is administered at microgram-level doses and is designed to engage and activate chemosensory neurons in the nasal cavity, which are connected to neural circuits in the brain that produce antidepressant effects. Unlike all currently approved oral antidepressants (ADs) and rapid-onset intravenous and intranasal ketamine-based therapy, we believe itruvone does not require systemic absorption or direct activity on neurons in the brain to produce antidepressant effects without the side effects and safety concerns that may be associated with current antidepressant therapies.

We are currently preparing and planning for potential U.S. Phase 2B clinical development of itruvone for treatment of  MDD.  In a randomized, double-blind, placebo-controlled parallel design Phase 2A clinical trial of itruvone in MDD and published in the peer-reviewed British Journal of Pharmaceutical and Medical Research, at a 6.4 μg dose administered intranasally twice daily for eight weeks, PH10 significantly reduced depressive symptoms as early as one week based on the 17-item Hamilton Depression Scale (HAM-D-17) scores compared to placebo (p=0.022). Itruvone was well-tolerated and did not cause psychological side effects (such as dissociation or hallucinations) or other safety concerns that may be associated with other approved pharmacological therapies for MDD. The trial was sponsored by Pherin Pharmaceuticals (Pherin), now a wholly-owned subsidiary of Vistagen, and was conducted in Mexico. Positive data from our recent U.S. IND-enabling Phase 1 trial demonstrated that there were no reported treatment-related serious adverse events (SAEs) or discontinuations due to adverse events in the trial. Overall, itruvone was well-tolerated and continued to demonstrate a favorable safety profile consistent with all other itruvone trials completed to date.

The U.S. FDA has granted Fast Track designation for the investigation of itruvone for the treatment of MDD. 

PH80 Nasal Spray for Womens Health Disorders

PH80 is an odorless, tasteless synthetic investigational pherine nasal spray with a novel, rapid-onset potential MOA that is fundamentally differentiated from the MOA of all currently approved treatments for vasomotor symptoms (hot flashes) due to menopause, premenstrual dysphoric disorder (PMDD), and other women’s health disorders and migraine headaches. PH80 activates chemosensory neurons in the nasal cavity connected to neural circuits that modulate the basal forebrain associated with the control of body temperature.

PH80 for Moderate to Severe Vasomotor Symptoms (hot flashes) due to Menopause. We recently reported positive results from a previously unpublished exploratory randomized, double-blind, placebo-controlled Phase 2A study of PH80 for the acute treatment of vasomotor symptoms (hot flashes) due to menopause sponsored by Pherin, now our wholly-owned subsidiary. This Phase 2A study conducted in a real-world setting demonstrated a statistically significant reduction in the daily number of menopausal hot flashes compared to placebo at the end of the first week of treatment (p=<0.001), and the improvement was maintained through each treatment week until the end of the four-week treatment period (p=<0.001). PH80 treatment also significantly reduced the severity, disruption in function, and sweating related to hot flashes during the treatment period as compared with placebo. PH80 was well-tolerated with no serious adverse events (SAEs), and the adverse event profiles were comparable between PH80 and placebo. All 36 subjects completed four weeks of treatment and no subject discontinued participation in the study as a result of TEAEs.

PH80 for Premenstrual Dysphoric Disorder (PMDD). We also recently reported positive results from a previously unpublished exploratory randomized, double-blind, placebo-controlled Phase 2A clinical study of PH80 for acute management of the symptoms of PMDD, including negative mood and physical and behavioral symptoms, in subjects with a regular menstrual cycle and at least a one-year history of PMDD. This Phase 2A study was sponsored by Pherin, now our wholly-owned subsidiary, and demonstrated a statistically significant improvement versus placebo in acute management of the symptoms of PMDD, including negative mood and physical and behavioral symptoms. The initial study visit occurred after the onset of symptoms. All subjects were administered a placebo nasal spray, and those who showed no symptom improvement were eligible to return for the second visit, which occurred after the onset of symptoms during the next menstrual cycle. At the second study visit, subjects were randomized to receive a single dose of 0.9 µg PH80 nasal spray or placebo in the clinic. PH80 demonstrated statistically and clinically significant improvement versus placebo in symptoms of PMDD using the subject-rated Penn Daily Symptom Report (DSR) as early as Day 4 and continuing to Day 6 (p=0.008). PH80 also demonstrated statistically and clinically significant improvement versus placebo at Day 6 on the clinician-rated Premenstrual Tension Scale (PMTS) total score (p=0.006). PH80 was well-tolerated with no SAEs. The most common TEAE was headache, reported by 17% in the placebo group and 7% in the PH80 group. No other TEAE occurred more than once per subject.

We are preparing to conduct certain nonclinical studies during the 2024 calendar year necessary to submit our U.S. IND for potential Phase 2B clinical development of PH80 in the U.S. for one or more women’s health indications.

PH15 Nasal Spray for Cognitive and Psychomotor Performance and Improvement

PH15 is an odorless, tasteless synthetic investigational pherine nasal spray with a novel, rapid-onset potential MOA that is fundamentally differentiated from the MOA of all currently approved treatments to improve cognitive impairment caused by mental fatigue and potentially other disorders. We believe intranasal PH15 has the potential to improve cognitive and psychomotor performance and improvement of reaction time in individuals with mental fatigue. We are currently evaluating the potential path forward for PH15, including an assessment of completed studies and studies we believe are necessary to submit a U.S. IND for potential further Phase 2 clinical development of PH15 in the U.S., including the appropriate indication for demonstrating improvement of cognitive function.

PH284 Nasal Spray for Cachexia

PH284 is an odorless, tasteless synthetic investigational pherine nasal spray with a novel, rapid-onset potential MOA that is fundamentally differentiated from the MOA of all currently approved treatments for the loss of appetite associated with chronic disorders such as cancer. Cachexia is a serious but under-recognized consequence of many chronic diseases with body mass loss of >10% and a prevalence of 5 to 15 %. We believe PH284 may have therapeutic potential for improving subjective feelings of hunger in patients with cachexia.  We are currently evaluating the potential path forward for PH284, including assessment of completed studies and studies we believe are necessary to submit a U.S. IND for potential further Phase 2 clinical development of PH15 for the treatment of cachexia, including the appropriate patient populations for demonstrating an increase in appetite and weight gain.

AV-101for Neurological Disorders

AV-101 (4-Cl-KYN) is a novel, oral prodrug that targets the NMDAR (N-methyl-D-aspartate receptor), an ionotropic glutamate receptor in the brain. Based on observations and findings from preclinical studies, we believe AV-101 has the potential to become a new oral treatment alternative for multiple neuroscience disorders, including levodopa-induced dyskinesia and neuropathic pain among others. We are currently assessing a path forward for potential Phase 2A clinical development of AV-101, either on our own or with collaborators, as a treatment for levodopa-induced dyskinesia associated with Parkinson’s disease therapy and possibly one or more additional neurological disorders involving the NMDAR receptor.

The U.S. FDA has granted Fast Track designation for the investigation of AV-101 for the treatment of neuropathic pain and for the adjunctive treatment of MDD.

DESCRIPTION OF DEBT SECURITIES

This section describes the general terms and provisions of debt securities that we may issue from time to time. We may issue debt securities, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any future debt securities we may offer under this prospectus, the applicable prospectus supplement will describe the specific terms of any debt securities offered through that prospectus supplement. The terms of any debt securities we offer under a prospectus supplement may differ from the terms we describe below.

We may offer debt securities which may be senior or subordinated. We refer to the senior debt securities and the subordinated debt securities collectively as debt securities. The following description summarizes the general terms and provisions of the debt securities. We will describe the specific terms of the debt securities and the extent, if any, to which the general provisions summarized below apply to any series of debt securities in the prospectus supplement relating to the series and any applicable free writing prospectus that we authorize to be delivered.

We may issue senior debt securities from time to time, in one or more series under a senior indenture to be entered into between us and a senior trustee to be named in a prospectus supplement, which we refer to as the senior trustee. We may issue subordinated debt securities from time to time, in one or more series under a subordinated indenture to be entered into between us and a subordinated trustee to be named in a prospectus supplement, which we refer to as the subordinated trustee. The forms of senior indenture and subordinated indenture are filed as exhibits to the registration statement of which this prospectus forms a part. Together, the senior indenture and the subordinated indenture are referred to as the indentures and, together, the senior trustee and the subordinated trustee are referred to as the trustees. This prospectus briefly outlines some of the provisions of the indentures. The following summary of the material provisions of the indentures is qualified in its entirety by the provisions of the indentures, including definitions of certain terms used in the indentures. Wherever we refer to particular sections or defined terms of the indentures, those sections or defined terms are incorporated by reference in this prospectus or the applicable prospectus supplement. You should review the indentures that are filed as exhibits to the registration statement of which this prospectus forms a part for additional information.

None of the indentures will limit the amount of debt securities that we may issue. The applicable indenture will provide that debt securities may be issued up to an aggregate principal amount authorized from time to time by us and may be payable in any currency or currency unit designated by us or in amounts determined by reference to an index.

General

The senior debt securities will constitute our unsecured and unsubordinated general obligations and will rank pari passu with our other unsecured and unsubordinated obligations, if any. The subordinated debt securities will constitute our unsecured and subordinated general obligations and will be junior in right of payment to our senior indebtedness (including senior debt securities), as described under the heading “– Certain Terms of the Subordinated Debt Securities – Subordination.” The debt securities will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries unless such subsidiaries expressly guarantee such debt securities.

The debt securities will be our unsecured obligations. Any secured debt or other secured obligations will be effectively senior to the debt securities to the extent of the value of the assets securing such debt or other obligations.

The applicable prospectus supplement and/or free writing prospectus will include any additional or different terms of the debt securities of any series being offered, including the following terms:

the title and type of the debt securities;

whether the debt securities will be senior or subordinated debt securities, and, with respect to debt securities issued under the subordinated indenture the terms on which they are subordinated;

the aggregate principal amount of the debt securities;

the price or prices at which we will sell the debt securities;

the maturity date or dates of the debt securities and the right, if any, to extend such date or dates;

the rate or rates, if any, per year, at which the debt securities will bear interest, or the method of determining such rate or rates;

10

the date or dates from which such interest will accrue, the interest payment dates on which such interest will be payable or the manner of determination of such interest payment dates and the related record dates;

the right, if any, to extend the interest payment periods and the duration of that extension;

the manner of paying principal and interest and the place or places where principal and interest will be payable;

provisions for a sinking fund, purchase fund or other analogous fund, if any;

any redemption dates, prices, obligations and restrictions on the debt securities;

the currency, currencies or currency units in which the debt securities will be denominated and the currency, currencies or currency units in which principal and interest, if any, on the debt securities may be payable;

any conversion or exchange features of the debt securities;

whether and upon what terms the debt securities may be defeased;

any events of default or covenants in addition to or in lieu of those set forth in the indenture;

whether the debt securities will be issued in definitive or global form or in definitive form only upon satisfaction of certain conditions;

whether the debt securities will be guaranteed as to payment or performance;

any special tax implications of the debt securities; and

any other material terms of the debt securities.

When we refer to “principal” in this section with reference to the debt securities, we are also referring to “premium, if any.”

We may from time to time, without notice to or the consent of the holders of any series of debt securities, create and issue further debt securities of any such series ranking equally with the debt securities of such series in all respects (or in all respects other than (1) the payment of interest accruing prior to the issue date of such further debt securities or (2) the first payment of interest following the issue date of such further debt securities). Such further debt securities may be consolidated and form a single series with the debt securities of such series and have the same terms as to status, redemption or otherwise as the debt securities of such series.

You may present debt securities for exchange and you may present debt securities for transfer in the manner, at the places and subject to the restrictions set forth in the debt securities and the applicable prospectus supplement. We will provide you those services without charge, although you may have to pay any tax or other governmental charge payable in connection with any exchange or transfer, as set forth in the indenture.

Debt securities may bear interest at a fixed rate or a floating rate. Debt securities bearing no interest or interest at a rate that at the time of issuance is below the prevailing market rate (original issue discount securities) may be sold at a discount below their stated principal amount. U.S. federal income tax considerations applicable to any such discounted debt securities or to certain debt securities issued at par which are treated as having been issued at a discount for U.S. federal income tax purposes will be described in the applicable prospectus supplement.

We may issue debt securities with the principal amount payable on any principal payment date, or the amount of interest payable on any interest payment date, to be determined by reference to one or more currency exchange rates, securities or baskets of securities, commodity prices or indices. You may receive a payment of principal on any principal payment date, or a payment of interest on any interest payment date, that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending on the value on such dates of the applicable currency, security or basket of securities, commodity or index. Information as to the methods for determining the amount of principal or interest payable on any date, the currencies, securities or baskets of securities, commodities or indices to which the amount payable on such date is linked and certain related tax considerations will be set forth in the applicable prospectus supplement.

11

certain other conditions are met.

No Protection in the Event of a Change in Control. Unless we indicate otherwise in a prospectus supplement with respect to a particular series of senior debt securities, the senior debt securities will not contain any provisions that may afford holders of the senior debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control).

Events of Default. Unless we indicate otherwise in a prospectus supplement with respect to a particular series of senior debt securities, the following are events of default under the senior indenture for any series of senior debt securities:

failure to pay interest on any senior debt securities of such series when due and payable, if that default continues for a period of 30 days (or such other period as may be specified for such series);

failure to pay principal on the senior debt securities of such series when due and payable whether at maturity, upon redemption, by declaration or otherwise (and, if specified for such series, the continuance of such failure for a specified period);

default in the performance of or breach of any of our covenants or agreements in the senior indenture applicable to senior debt securities of such series, other than a covenant breach which is specifically dealt with elsewhere in the senior indenture, and that default or breach continues for a period of 90 days after we receive written notice from the trustee or from the holders of 25% or more in aggregate principal amount of the senior debt securities of such series;

certain events of bankruptcy or insolvency, whether or not voluntary; and

any other event of default provided for in such series of senior debt securities as may be specified in the applicable prospectus supplement.

The default by us under any other debt, including any other series of debt securities, is not a default under the senior indenture.

If an event of default other than an event of default specified in the fourth bullet point above occurs with respect to a series of senior debt securities and is continuing under the senior indenture, then, and in each such case, either the trustee or the holders of not less than 25% in aggregate principal amount of such series then outstanding under the senior indenture (each such series voting as a separate class) by written notice to us and to the trustee, if such notice is given by the holders, may, and the trustee at the request of such holders shall, declare the principal amount of and accrued interest on such series of senior debt securities to be immediately due and payable, and upon this declaration, the same shall become immediately due and payable.

If an event of default specified in the fourth bullet point above occurs and is continuing, the entire principal amount of and accrued interest on each series of senior debt securities then outstanding shall become immediately due and payable.

Unless otherwise specified in the prospectus supplement relating to a series of senior debt securities originally issued at a discount, the amount due upon acceleration shall include only the original issue price of the senior debt securities, the amount of original issue discount accrued to the date of acceleration and accrued interest, if any.

12

Upon certain conditions, declarations of acceleration may be rescinded and annulled and past defaults may be waived by the holders of a majority in aggregate principal amount of all the senior debt securities of such series affected by the default, each series voting as a separate class. Furthermore, subject to various provisions in the senior indenture, the holders of a majority in aggregate principal amount of a series of senior debt securities, by notice to the trustee, may waive an existing default or event of default with respect to such senior debt securities and its consequences, except a default in the payment of principal of or interest on such senior debt securities or in respect of a covenant or provision of the senior indenture which cannot be modified or amended without the consent of the holders of each such senior debt security. Upon any such waiver, such default shall cease to exist, and any event of default with respect to such senior debt securities shall be deemed to have been cured, for every purpose of the senior indenture; but no such waiver shall extend to any subsequent or other default or event of default or impair any right consequent thereto.

The holders of a majority in aggregate principal amount of a series of senior debt securities may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such senior debt securities. However, the trustee may refuse to follow any direction that conflicts with law or the senior indenture, that may involve the trustee in personal liability or that the trustee determines in good faith may be unduly prejudicial to the rights of holders of such series of senior debt securities not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from holders of such series of senior debt securities. A holder may not pursue any remedy with respect to the senior indenture or any series of senior debt securities unless:

the holder gives the trustee written notice of a continuing event of default;

the holders of at least 25% in aggregate principal amount of such series of senior debt securities make a written request to the trustee to pursue the remedy in respect of such event of default;

the requesting holder or holders offer the trustee indemnity satisfactory to the trustee against any costs, liability or expense;

the trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

during such 60-day period, the holders of a majority in aggregate principal amount of such series of senior debt securities do not give the trustee a direction that is inconsistent with the request.

These limitations, however, do not apply to the right of any holder of a senior debt security to receive payment of the principal of and interest on such senior debt security in accordance with the terms of such debt security, or to bring suit for the enforcement of any such payment in accordance with the terms of such debt security, on or after the due date for the senior debt securities, which right shall not be impaired or affected without the consent of the holder.

The senior indenture requires certain of our officers to certify, on or before a fixed date in each year in which any senior debt security is outstanding, as to their knowledge of our compliance with all covenants, agreements and conditions under the senior indenture.

Satisfaction and Discharge. We can satisfy and discharge our obligations to holders of any series of debt securities if:

we pay or cause to be paid, as and when due and payable, the principal of and any interest on all senior debt securities of such series outstanding under the senior indenture; or

all senior debt securities of such series have become due and payable or will become due and payable within one year (or are to be called for redemption within one year) and we deposit in trust a combination of cash and U.S. government or U.S. government agency obligations that will generate enough cash to make interest, principal and any other payments on the debt securities of that series on their various due dates.

Under current U.S. federal income tax law, the deposit and our legal release from the debt securities would be treated as though we took back your debt securities and gave you your share of the cash and debt securities or bonds deposited in trust. In that event, you could recognize a gain or loss on the debt securities you give back to us. Purchasers of the debt securities should consult their own advisers with respect to the tax consequences to them of such deposit and discharge, including the applicability and effect of tax laws other than the U.S. federal income tax law.

Defeasance. Unless the applicable prospectus supplement provides otherwise, the following discussion of legal defeasance and discharge and covenant defeasance will apply to any series of debt securities issued under the indentures.

13

Legal Defeasance. We can legally release ourselves from any payment or other obligations on the debt securities of any series (called “legal defeasance”) if certain conditions are met, including the following:

We deposit in trust for your benefit and the benefit of all other direct holders of the debt securities of the same series a combination of cash and U.S. government or U.S. government agency obligations that will generate enough cash to make interest, principal and any other payments on the debt securities of that series on their various due dates.

There is a change in current U.S. federal income tax law or an Internal Revenue Service (“IRS”) ruling that lets us make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and instead repaid the debt securities ourselves when due. Under current U.S. federal income tax law, the deposit and our legal release from the debt securities would be treated as though we took back your debt securities and gave you your share of the cash and debt securities or bonds deposited in trust. In that event, you could recognize gain or loss on the debt securities you give back to us.

We deliver to the trustee a legal opinion of our counsel confirming the tax law change or ruling described above.

If we accomplish legal defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the debt securities. You could not look to us for repayment in the event of any shortfall.

Covenant Defeasance. Without any change of current U.S. federal tax law, we can make the same type of deposit described above and be released from some of the covenants in the debt securities (called “covenant defeasance”). In that event, you would lose the protection of those covenants but would gain the protection of having money and securities set aside in trust to repay the debt securities. In order to achieve covenant defeasance, we must do the following (among other things):

We must deposit in trust for your benefit and the benefit of all other direct holders of the debt securities of the same series a combination of cash and U.S. government or U.S. government agency obligations that will generate enough cash to make interest, principal and any other payments on the debt securities of that series on their various due dates.

We must deliver to the trustee a legal opinion of our counsel confirming that under current U.S. federal income tax law we may make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and instead repaid the debt securities ourselves when due.

If we accomplish covenant defeasance, you could still look to us for repayment of the debt securities if there were a shortfall in the trust deposit. In fact, if one of the events of default occurred (such as our bankruptcy) and the debt securities become immediately due and payable, there may be such a shortfall. Depending on the events causing the default, you may not be able to obtain payment of the shortfall.

Modification and Waiver. We and the trustee may amend or supplement the senior indenture or the senior debt securities without the consent of any holder:

to convey, transfer, assign, mortgage or pledge any assets as security for the senior debt securities of one or more series;

to evidence the succession of a corporation, limited liability company, partnership or trust to us, and the assumption by such successor of our covenants, agreements and obligations under the senior indenture or to otherwise comply with the covenant relating to mergers, consolidations and sales of assets;

to comply with requirements of the SEC in order to effect or maintain the qualification of the senior indenture under the Trust Indenture Act of 1939, as amended;

to add to our covenants such new covenants, restrictions, conditions or provisions for the protection of the holders, and to make the occurrence, or the occurrence and continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of default;

to cure any ambiguity, defect or inconsistency in the senior indenture or in any supplemental indenture or to conform the senior indenture or the senior debt securities to the description of senior debt securities of such series set forth in this prospectus or any applicable prospectus supplement;

to provide for or add guarantors with respect to the senior debt securities of any series;

14

to establish the form or forms or terms of the senior debt securities as permitted by the senior indenture;

to evidence and provide for the acceptance of appointment under the senior indenture by a successor trustee, or to make such changes as shall be necessary to provide for or facilitate the administration of the trusts in the senior indenture by more than one trustee;

to add to, delete from or revise the conditions, limitations and restrictions on the authorized amount, terms, purposes of issue, authentication and delivery of any series of senior debt securities;

to make any change to the senior debt securities of any series so long as no senior debt securities of such series are outstanding; or

to make any change that does not adversely affect the rights of any holder in any material respect.

Other amendments and modifications of the senior indenture or the senior debt securities issued may be made, and our compliance with any provision of the senior indenture with respect to any series of senior debt securities may be waived, with the consent of the holders of a majority of the aggregate principal amount of the outstanding senior debt securities of all series affected by the amendment or modification (voting together as a single class); provided, however, that each affected holder must consent to any modification, amendment or waiver that:

extends the final maturity of any senior debt securities of such series;

reduces the principal amount of any senior debt securities of such series;

reduces the rate or extends the time of payment of interest on any senior debt securities of such series;

reduces the amount payable upon the redemption of any senior debt securities of such series;

changes the currency of payment of principal of or interest on any senior debt securities of such series;

reduces the principal amount of original issue discount securities payable upon acceleration of maturity or the amount provable in bankruptcy;

waives an uncured default in the payment of principal of or interest on the senior debt securities (except in the case of a rescission of acceleration as described above);

changes the provisions relating to the waiver of past defaults or changes or impairs the right of holders to receive payment or to institute suit for the enforcement of any payment or conversion of any senior debt securities of such series on or after the due date therefor;

modifies any of the provisions of these restrictions on amendments and modifications, except to increase any required percentage or to provide that certain other provisions cannot be modified or waived without the consent of the holder of each senior debt security of such series affected by the modification; or

reduces the above-stated percentage of outstanding senior debt securities of such series whose holders must consent to a supplemental indenture or modifies or amends or waives certain provisions of or defaults under the senior indenture.

It shall not be necessary for the holders to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if the holders’ consent approves the substance thereof. After an amendment, supplement or waiver of the senior indenture in accordance with the provisions described in this section becomes effective, the trustee must give to the holders affected thereby certain notice briefly describing the amendment, supplement or waiver. Any failure by the trustee to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplemental indenture or waiver.

No Personal Liability of Incorporators, Stockholders, Officers, Directors. The senior indenture provides that no recourse shall be had under any obligation, covenant or agreement of ours in the senior indenture or any supplemental indenture, or in any of the senior debt securities or because of the creation of any indebtedness represented thereby, against any of our incorporators, stockholders, officers or directors, past, present or future, or of any predecessor or successor entity thereof under any law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. Each holder, by accepting the senior debt securities, waives and releases all such liability.

Concerning the Trustee. The senior indenture provides that, except during the continuance of an event of default, the trustee will not be liable except for the performance of such duties as are specifically set forth in the senior indenture. If an event of default has occurred and is continuing, the trustee will exercise such rights and powers vested in it under the senior indenture and will use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs.

15

The senior indenture and the provisions of the Trust Indenture Act of 1939 incorporated by reference therein contain limitations on the rights of the trustee thereunder, should it become a creditor of ours or our subsidiaries, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The trustee is permitted to engage in other transactions, provided that if it acquires any conflicting interest (as defined in the Trust Indenture Act), it must eliminate such conflict or resign.

We may have normal banking relationships with the senior trustee in the ordinary course of business.

Unclaimed Funds. All funds deposited with the trustee or any paying agent for the payment of principal, premium, interest or additional amounts in respect of the senior debt securities that remain unclaimed for two years after the date upon which such principal, premium or interest became due and payable will be repaid to us. Thereafter, any right of any holder of senior debt securities to such funds shall be enforceable only against us, and the trustee and paying agents will have no liability therefor.

Governing Law. The senior indenture and the senior debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York.

Certain Terms of the Subordinated Debt Securities

Other than the terms of the subordinated indenture and subordinated debt securities relating to subordination or otherwise as described in the prospectus supplement relating to a particular series of subordinated debt securities, the terms of the subordinated indenture and subordinated debt securities are identical in all material respects to the terms of the senior indenture and senior debt securities.

Additional or different subordination terms may be specified in the prospectus supplement applicable to a particular series.

Subordination. The indebtedness evidenced by the subordinated debt securities is subordinate to the prior payment in full of all of our senior indebtedness, as defined in the subordinated indenture. During the continuance beyond any applicable grace period of any default in the payment of principal, premium, interest or any other payment due on any of our senior indebtedness, we may not make any payment of principal of or interest on the subordinated debt securities (except for certain sinking fund payments). In addition, upon any payment or distribution of our assets upon any dissolution, winding-up, liquidation or reorganization, the payment of the principal of and interest on the subordinated debt securities will be subordinated to the extent provided in the subordinated indenture in right of payment to the prior payment in full of all our senior indebtedness. Because of this subordination, if we dissolve or otherwise liquidate, holders of our subordinated debt securities may receive less, ratably, than holders of our senior indebtedness. The subordination provisions do not prevent the occurrence of an event of default under the subordinated indenture.

The term “senior indebtedness” of a person means with respect to such person the principal of, premium, if any, interest on, and any other payment due pursuant to any of the following, whether outstanding on the date of the subordinated indenture or incurred by that person in the future:

all of the indebtedness of that person for money borrowed;

all of the indebtedness of that person evidenced by notes, debentures, bonds or other securities sold by that person for money;

all of the lease obligations that are capitalized on the books of that person in accordance with generally accepted accounting principles;

all indebtedness of others of the kinds described in the first two bullet points above and all lease obligations of others of the kind described in the third bullet point above that the person, in any manner, assumes or guarantees or that the person in effect guarantees through an agreement to purchase, whether that agreement is contingent or otherwise; and

all renewals, extensions or refundings of indebtedness of the kinds described in the first, second or fourth bullet point above and all renewals or extensions of leases of the kinds described in the third or fourth bullet point above;

unless, in the case of any particular indebtedness, renewal, extension or refunding, the instrument creating or evidencing it or the assumption or guarantee relating to it expressly provides that such indebtedness, renewal, extension or refunding is not superior in right of payment to the subordinated debt securities. Our senior debt securities constitute senior indebtedness for purposes of the subordinated debt indenture.

DESCRIPTION OF CAPITAL STOCK

General

The following description of our capital stock is intended as a summary only and therefore is not a complete description of our capital stock. This description is based upon, and is qualified by reference to, our Restated and Amended Articles of Incorporation, as amended (our “Charter”), our Amended and Restated Bylaws, as amended (our “Bylaws”), and applicable provisions of Nevada corporate law. You should read our Charter and Bylaws for the provisions that are important to you.

Our authorized capital stock consists of 325,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of preferred stock, $0.001 par value per share, all of which preferred stock is undesignated. The following description of our capital stock and provisions of our Charter and Bylaws are summaries and are qualified by reference to our Charter and Bylaws. Copies of these documents are filed with the SEC as exhibits to our Annual Report on Form 10-K for the year ended March 31, 2023, filed with the SEC on June 28, 2023.

The following is a description of our common stock and certain provisions of our Charter, and our amended and restated bylaws, and certain provisions of Nevada law.

We may elect or be required to amend our Charter to increase the number of shares of common stock authorized for issuance prior to completing sales of shares of our common stock, or securities convertible and/or exchangeable into shares of our common stock described in this prospectus and/or any accompanying prospectus supplement.

Common Stock

This section describes the general terms of our common stock that we may offer from time to time. For more detailed information, a holder of our common stock should refer to our Charter and our Bylaws.

Except as otherwise expressly provided in our Charter, or as required by applicable law, all shares of our common stock have the same rights and privileges and rank equally, share ratably and are identical in all respects as to all matters, including, without limitation, those described below. All outstanding shares of common stock are fully paid and nonassessable.

Voting Rights     Each holder of our common stock is entitled to cast one vote for each share of common stock held on all matters submitted to a vote of stockholders. Cumulative voting for election of directors is not allowed under our Charter, which means that a plurality of the shares voted can elect all of the directors then outstanding for election. Except as otherwise provided under Nevada law or our Charter and Bylaws, on matters other than election of directors, action on a matter is approved if the votes cast favoring the action exceed the votes cast opposing the action.

Dividend Rights   The holders of outstanding shares of our common stock are entitled to receive dividends out of funds legally available, if our Board of Directors (our “Board”), in its discretion, determines to issue a dividend, and only at the times and in the amounts that our Board may determine. Our Board is not obligated to declare a dividend. We have not paid any dividends on our common stock in the past and we do not intend to pay dividends in the foreseeable future.

Liquidation Rights Upon our liquidation, dissolution or winding-up, the holders of our common stock will be entitled to share equally, identically and ratably in all assets remaining, subject to the prior satisfaction of all outstanding debt and liabilities and the preferential rights and payment of liquidation preferences, if any, on any outstanding shares of preferred stock.

No Preemptive or Similar Rights Our common stock is not subject to conversion, redemption, sinking fund or similar provisions.

Listing on The Nasdaq Capital Market Our common stock is listed on The Nasdaq Capital Market under the symbol “VTGN.”

Authorized but Unissued Shares The authorized but unissued shares of common stock are available for future issuance without stockholder approval, subject to any limitations imposed by applicable listing rules of The Nasdaq Stock Market. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock could make it more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

17

Transfer Agent and Registrar The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

Securities Offered Under Prior Registration Statements

On October 2, 2023, we entered into an underwriting agreement (the “Underwriting Agreement”) with Jefferies LLC, Stifel, Nicolaus & Company, Incorporated, and William Blair & Company, L.L.C., as the representatives of the underwriters listed on Schedule A attached thereto (the “Underwriters”), in connection with the underwritten offering, issuance and sale by us of 15,010,810 shares common stock, pre-funded warrants to purchase up to 3,577,240 shares of common stock (the “Pre-Funded Warrants”), warrants to purchase up to 9,294,022 shares of common stock (or pre-funded warrants to purchase up to 9,294,022 shares of common stock in lieu thereof) (the “Tranche 1 Warrants”) and warrants to purchase 11,265,086 shares of common stock (or pre-funded warrants to purchase up to 11,265,086 shares of common stock in lieu thereof) (the “Tranche 2 Warrants”).

We are also offering shares of common stock issuable from time to time upon exercise of our pre-funded warrants, Tranche 1 Warrants and Tranche 2 Warrants. The following is a summary of certain terms and conditions of the pre-funded warrants, Tranche 1 Warrants and Tranche 2 Warrants, which summary is subject in all respect to the provisions contained in the pre-funded warrants, Tranche 1 Warrants and Tranche 2 Warrants. Forms of each of the pre-funded warrants, Tranche 1 Warrants and Tranche 2 Warrants are filed with the SEC as exhibits to our Current Report on Form 8-K, dated October 4, 2023 and incorporated by reference herein.

Pre-Funded Warrants

Exercisability. The pre-funded warrants are exercisable at any time after their original issuance. The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and by payment in full in immediately available funds for the number of shares of common stock purchased upon such exercise. As an alternative to payment in immediately available funds, the holder may, in its sole discretion, elect to exercise the pre-funded warrant through a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the pre-funded warrant. No fractional shares of common stock will be issued in connection with the exercise of a pre-funded warrant. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price.

Exercise Limitations. A holder will not have the right to exercise any portion of the pre-funded warrant if the holder (together with its affiliates) would beneficially own in excess of 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. However, any holder may elect, prior to issuance of its pre-funded warrant, to include a provision in such holder’s pre-funded warrant that will permit such holder to elect to increase or decrease such percentage to any other percentage upon at least 61 days’ prior notice from the holder to us.

Exercise Price. The exercise price per whole share of our common stock purchasable upon the exercise of the pre-funded warrants is $0.001 per share of common stock. The exercise price of the pre-funded warrants is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock and also upon any distributions of assets, including cash, stock or other property to our stockholders.

Transferability. Subject to applicable laws, the pre-funded warrants may be offered for sale, sold, transferred or assigned without our consent.

Exchange Listing. The pre-funded warrants are not listed, and we do not intend to list the pre-funded warrants on The Nasdaq Capital Market, any other national securities exchange or any other nationally recognized trading system.

Fundamental Transactions. In the event of a fundamental transaction, as described in the pre-funded warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, the holders of the pre-funded warrants will be entitled to receive upon exercise of the pre-funded warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the pre-funded warrants immediately prior to such fundamental transaction.

18

Rights as a Stockholder. Except by virtue of such holder’s ownership of shares of our common stock, the holder of a pre-funded warrant does not have the rights or privileges of a holder of our common stock, including any voting rights, until the holder exercises the pre-funded warrant.

Tranche 1 Warrants

Exercisability. The Tranche 1 Warrants are exercisable at any time after their original issuance and will expire 60 days after the later of (i) the date on which we first publicly disclose, whether by press release or Form 8-K filing, the top-line data for our PALISADE-3 study and (ii) the date on which we first publicly disclose, whether by press release or Form 8-K filing, the top-line data for our PALISADE-4 study. The Tranche 1 Warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and by payment in full in immediately available funds for the number of shares of common stock or pre-funded warrants purchased upon such exercise. As an alternative to payment in immediately available funds, the holder may if and only if at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the common stock or pre-funded warrants to the holder, then in its sole discretion, elect to exercise the Tranche 2 Warrant through a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock or pre-funded warrants determined according to the formula set forth in the Tranche 1 Warrant. No fractional shares of common stock or pre-funded warrants will be issued in connection with the exercise of a Tranche 1 Warrant. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price.

Exercise Limitations. A holder will not have the right to exercise any portion of the Tranche 1 Warrant if the holder (together with its affiliates) would beneficially own in excess of 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Tranche 1 Warrant. However, any holder may elect, prior to issuance of its Tranche 1 Warrant, to include a provision in such holder’s Tranche 1 Warrant that will permit such holder to elect to increase or decrease such percentage to any other percentage upon at least 61 days’ prior notice from the holder to us.

Exercise Price.

Exchange Listing. The Tranche 1 Warrants are not listed, and we do not intend to list the Tranche 1 Warrants on The Nasdaq Capital Market, any other national securities exchange or any other nationally recognized trading system.

Fundamental Transactions. In the event of a fundamental transaction, as described in the Tranche 1 Warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, the holders of the Tranche 1 Warrants will be entitled to receive upon exercise of the Tranche 1 Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Tranche 1 Warrants immediately prior to such fundamental transaction.

Rights as a Stockholder. Except by virtue of such holder’s ownership of shares of our common stock, the holder of a Tranche 1 Warrant does not have the rights or privileges of a holder of our common stock, including any voting rights, until the holder exercises the Tranche 1 Warrant.

You should review the form of Tranche 2 Warrants, which will be filed as an exhibit to a Current Report on Form 8-K, for a complete description of the terms and conditions applicable to the Tranche 2 Warrants.

Exercisability. The Tranche 2 Warrants are exercisable at any time after their original issuance and will expire on the five year anniversary of the original issuance. The Tranche 2 Warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and by payment in full in immediately available funds for the number of shares of common stock or pre-funded warrants purchased upon such exercise. As an alternative to payment in immediately available funds, the holder may, in its sole discretion, elect to exercise the Tranche 2 Warrant through a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock or pre-funded warrants determined according to the formula set forth in the Tranche 2 Warrant. No fractional shares of common stock or pre-funded warrants will be issued in connection with the exercise of a Tranche 2 Warrant. In lieu of fractional shares, we will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price.

Exercise Limitations. A holder will not have the right to exercise any portion of the Tranche 2 Warrant if the holder (together with its affiliates) would beneficially own in excess of 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Tranche 2 Warrant. However, any holder may elect, prior to issuance of its Tranche 2 Warrant, to include a provision in such holder’s Tranche 2 Warrant that will permit such holder to elect to increase or decrease such percentage to any other percentage upon at least 61 days’ prior notice from the holder to us.

In the event of a fundamental transaction, as described in the Tranche 2 Warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, the holders of the Tranche 2 Warrants will be entitled to receive upon exercise of the Tranche 2 Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Tranche 2 Warrants immediately prior to such fundamental transaction.

DESCRIPTION OF PREFERRED STOCK

This section describes the general terms and provisions of our authorized preferred stock, as well as preferred stock that we may offer from time to time. The applicable prospectus supplement will describe the specific terms of the shares of preferred stock offered through that prospectus supplement, which may differ from the terms we describe below. We will filea copy of the certificate of designation that contains the terms of each new series of preferred stock with the SEC each time we issue a new series of preferred stock, and these certificates of designation will be incorporated by reference into the registration statement of which this prospectus is a part. Each certificate of designation will establish the number of shares included in a designated series and fix the designation, powers, privileges, preferences and rights of the shares of each series as well as any applicable qualifications, limitations or restrictions. A holder of our preferred stock should refer to the applicable certificate of designation, our Charter, and the applicable prospectus supplement (and any related free writing prospectus that we may authorize to be provided to you) for more specific information.

We are authorized, subject to limitations prescribed by Nevada law, to issue up to 10.0 million shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each series and to fix the designation, powers, preferences and rights of the shares of each series and any of its qualifications, limitations or restrictions.

Our Board may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of the common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of the Company and may adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock.

Shares of Preferred Stock Issuable Pursuant to this Prospectus

Any preferred stock offered pursuant to this prospectus will have the terms described below unless otherwise provided in the prospectus supplement relating to a particular series of preferred stock. You should read the prospectus supplement relating to the particular series of preferred stock being offered for specific terms, including:

the designation and stated value per share of the preferred stock and the number of shares offered;

the amount of liquidation preference per share;

the price at which the preferred stock will be issued;

the dividend rate, or method of calculation of dividends, the dates on which dividends will be payable, whether dividends will be cumulative or noncumulative and, if cumulative, the dates from which dividends will commence to accumulate;

any redemption or sinking fund provisions;

if other than the currency of the United States, the currency or currencies including composite currencies in which the preferred stock is denominated and/or in which payments will or may be payable;

any conversion provisions;

any special tax implications of the preferred stock; and

any other rights, preferences, privileges, limitations and restrictions on the preferred stock.

The preferred stock will, when issued, be fully paid and nonassessable. Unless otherwise specified in the prospectus supplement, each series of preferred stock will rank equally as to dividends and liquidation rights in all respects with each other series of preferred stock. The rights of holders of shares of each series of preferred stock will be subordinate to those of our general creditors.

Rank. Unless otherwise specified in the prospectus supplement, the preferred stock will, with respect to dividend rights and rights upon our liquidation, dissolution or winding up of our affairs, rank:

senior to our common stock and to all equity securities ranking junior to such preferred stock with respect to dividend rights or rights upon our liquidation, dissolution or winding up of our affairs;

21

on a parity with all equity securities issued by us, the terms of which specifically provide that such equity securities rank on a parity with the preferred stock with respect to dividend rights or rights upon our liquidation, dissolution or winding up of our affairs; and

junior to all equity securities issued by us, the terms of which specifically provide that such equity securities rank senior to the preferred stock with respect to dividend rights or rights upon our liquidation, dissolution or winding up of our affairs.

The term “equity securities” does not include convertible debt securities.

Dividends. Holders of the preferred stock of each series will be entitled to receive, when, as and if declared by our Board, cash dividends at such rates and on such dates described in the prospectus supplement. Different series of preferred stock may be entitled to dividends at different rates or based on different methods of calculation. The dividend rate may be fixed or variable or both. Dividends will be payable to the holders of record as they appear on our stock books on record dates fixed by our board of directors, as specified in the applicable prospectus supplement.

Dividends on any series of preferred stock may be cumulative or noncumulative, as described in the applicable prospectus supplement. If our Board does not declare a dividend payable on a dividend payment date on any series of noncumulative preferred stock, then the holders of that noncumulative preferred stock will have no right to receive a dividend for that dividend payment date, and we will have no obligation to pay the dividend accrued for that period, whether or not dividends on that series are declared payable on any future dividend payment dates. Dividends on any series of cumulative preferred stock will accrue from the date we initially issue shares of such series or such other date specified in the applicable prospectus supplement.

No dividends may be declared or paid or funds set apart for the payment of any dividends on any parity securities unless full dividends have been paid or set apart for payment on the preferred stock. If full dividends are not paid, the preferred stock will share dividends pro rata with the parity securities.

No dividends may be declared or paid or funds set apart for the payment of dividends on any junior securities unless full dividends for all dividend periods terminating on or prior to the date of the declaration or payment will have been paid or declared and a sum sufficient for the payment set apart for payment on the preferred stock.

Liquidation Preference. Upon any voluntary or involuntary liquidation, dissolution or winding up of our affairs, then, before we make any distribution or payment to the holders of any common stock or any other class or series of our capital stock ranking junior to the preferred stock in the distribution of assets upon any liquidation, dissolution or winding up of our affairs, the holders of each series of preferred stock shall be entitled to receive out of assets legally available for distribution to stockholders, liquidating distributions in the amount of the liquidation preference per share set forth in the prospectus supplement, plus any accrued and unpaid dividends thereon. Such dividends will not include any accumulation in respect of unpaid noncumulative dividends for prior dividend periods. Unless otherwise specified in the prospectus supplement, after payment of the full amount of their liquidating distributions, the holders of preferred stock will have no right or claim to any of our remaining assets. Upon any such voluntary or involuntary liquidation, dissolution or winding up, if our available assets are insufficient to pay the amount of the liquidating distributions on all outstanding preferred stock and the corresponding amounts payable on all other classes or series of our capital stock ranking on parity with the preferred stock and all other such classes or series of shares of capital stock ranking on parity with the preferred stock in the distribution of assets, then the holders of the preferred stock and all other such classes or series of capital stock will share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be entitled.

Upon any such liquidation, dissolution or winding up and if we have made liquidating distributions in full to all holders of preferred stock, we will distribute our remaining assets among the holders of any other classes or series of capital stock ranking junior to the preferred stock according to their respective rights and preferences and, in each case, according to their respective number of shares. For such purposes, our consolidation or merger with or into any other corporation, trust or entity, or the sale, lease or conveyance of all or substantially all of our property or assets will not be deemed to constitute a liquidation, dissolution or winding up of our affairs.

Redemption. If so provided in the applicable prospectus supplement, the preferred stock will be subject to mandatory redemption or redemption at our option, as a whole or in part, in each case upon the terms, at the times and at the redemption prices set forth in such prospectus supplement.

22

The prospectus supplement relating to a series of preferred stock that is subject to mandatory redemption will specify the number of shares of preferred stock that shall be redeemed by us in each year commencing after a date to be specified, at a redemption price per share to be specified, together with an amount equal to all accrued and unpaid dividends thereon to the date of redemption.

Voting Rights. Holders of preferred stock will not have any voting rights, except as required by law or as indicated in the applicable prospectus supplement.

Unless otherwise provided for under the terms of any series of preferred stock, no consent or vote of the holders of shares of preferred stock or any series thereof shall be required for any amendment to our restated certificate of incorporation that would increase the number of authorized shares of preferred stock or the number of authorized shares of any series thereof or decrease the number of authorized shares of preferred stock or the number of authorized shares of any series thereof (but not below the number of authorized shares of preferred stock or such series, as the case may be, then outstanding).

Conversion Rights. The terms and conditions, if any, upon which any series of preferred stock is convertible into our common stock will be set forth in the applicable prospectus supplement relating thereto. Such terms will include the number of shares of common stock into which the shares of preferred stock are convertible, the conversion price, rate or manner of calculation thereof, the conversion period, provisions as to whether conversion will be at our option or at the option of the holders of the preferred stock, the events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption.

Transfer Agent and Registrar. The transfer agent and registrar for the preferred stock will be set forth in the applicable prospectus supplement.

23

DESCRIPTION OF WARRANTS

The following description, together with the additional information we include in any applicable prospectus supplements or free writing prospectus, summarizes the material terms and provisions of the warrants that we may offer under this prospectus. Warrants may be offered independently or together with common stock or preferred stock and/or debt securities offered by any prospectus supplement or free writing prospectus, and may be attached to or separate from those securities. While the terms we have summarized below will generally apply to any future warrants we may offer under this prospectus, we will describe the particular terms of any warrants that we may offer in more detail in the applicable prospectus supplement or free writing prospectus. The terms of any warrants we offer under a prospectus supplement or free writing prospectus may differ from the terms we describe below.

We may issue warrants to purchase common stock, preferred stock or debt securities. We may offer warrants separately or together with one or more additional warrants, common stock, preferred stock or debt securities, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. If we issue warrants as part of a unit, the accompanying prospectus supplement will specify whether those warrants may be separated from the other securities in the unit prior to the expiration date of the warrants. The applicable prospectus supplement will also describe the following terms of any warrants:

the specific designation and aggregate number of, and the offering price at which we will issue, the warrants;

the currency or currency units in which the offering price, if any, and the exercise price are payable;

the date on which the right to exercise the warrants will begin and the date on which that right will expire or, if you may not continuously exercise the warrants throughout that period, the specific date or dates on which you may exercise the warrants;

whether the warrants are to be sold separately or with other securities as parts of units;

whether the warrants will be issued in definitive or global form or in any combination of these forms, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any security included in that unit;

any applicable material U.S. federal income tax consequences;

the identity of the warrant agent for the warrants and of any other depositaries, execution or paying agents, transfer agents, registrars or other agents;

the proposed listing, if any, of the warrants or any securities purchasable upon exercise of the warrants on any securities exchange;

the designation and terms of any equity securities purchasable upon exercise of the warrants;

the designation, aggregate principal amount, currency and terms of any debt securities that may be purchased upon exercise of the warrants;

if applicable, the designation and terms of the preferred stock with which the warrants are issued and the number of warrants issued with each security;

if applicable, the date from and after which any warrants issued as part of a unit and the related debt securities, preferred stock, or common stock will be separately transferable;

the number of shares of common stock, preferred stock purchasable upon exercise of a warrant and the price at which those shares may be purchased;

if applicable, the minimum or maximum amount of the warrants that may be exercised at any one time;

information with respect to book-entry procedures, if any;

the anti-dilution provisions of, and other provisions for changes to or adjustment in the exercise price of, the warrants, if any;

any redemption or call provisions; and

any additional terms of the warrants, including terms, procedures and limitations relating to the exchange or exercise of the warrants.

In the event that we issue warrants, we may issue the warrants under a warrant agreement, which, if applicable, we will enter into with a warrant agent to be selected by us. Forms of these warrant agreements and forms of the warrant certificates representing the warrants, and the complete warrant agreements and forms of warrant certificates containing the terms of the warrants being offered, will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC. We use the term “warrant agreement” to refer to any of these warrant agreements. We use the term “warrant agent” to refer to the warrant agent under any of these warrant agreements. The warrant agent will act solely as an agent of ours in connection with the warrants and will not act as an agent for the holders or beneficial owners of the warrants.

24

DESCRIPTION OF OUR UNITS

This section outlines some of the provisions of the units and the unit agreements. This information may not be complete in all respects and is qualified entirely by reference to the unit agreement with respect to the units of any particular series. The specific terms of any series of units will be described in the applicable prospectus supplement. If so described in a particular prospectus supplement, the specific terms of any series of units may differ from the general description of terms presented below.

We may issue units comprised of one or more of the other securities that may be offered under this prospectus, in any combination. The following, together with the additional information we may include in the applicable prospectus supplement, summarizes the material terms and provisions of the units that we may offer under this prospectus. While the terms summarized below will apply generally to any units we may offer, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement.

Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time, or at any time before a specified date.

Any applicable prospectus supplement will describe:

the material terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

any material provisions relating to the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units;

any special tax implications of the units; and

any material provisions of the governing unit agreement that differ from those described above.

25

DESCRIPTIONOF CERTAIN PROVISIONS OF NEVADA LAW AND

OUR CHARTER AND BYLAWS

Transactions with Interested Persons

Under the Nevada Revised Statutes (the “NRS”) a transaction with the Company (i) in which a Company director or officer has a direct or indirect interest, or (ii) involving another corporation, firm or association in which one or more of the Company’s directors or officers are directors or officers of the corporation, firm or association or have a financial interest in the corporation firm or association, is not void or voidable solely because of the director’s or officer’s interest or common role in the transaction if any one of the following circumstances exists:

the fact of the common directorship, office or financial interest is known to our Board or a committee of our Board and a majority of disinterested directors on the Board (or on the committee) authorize, approved or ratify the transaction in good faith;

the fact of the common directorship, office or financial interest is known to the stockholders and stockholders holding a majority of the shares, including shares held by the common or interested directors or officers, authorize, approve or ratify the transaction in good faith;

the fact of the common directorship, office or financial interest is not known to the director or officer at the time the transaction is brought to the Board for action; or

the transaction is fair to the Company at the time it is authorized or approved.

Anti-Takeover Provisions

Our Charter and Nevada law include certain provisions which may have the effect of delaying or deterring a change in control or in our management or encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts. These provisions include authorized blank check preferred stock, restrictions on business combinations, and the availability of authorized but unissued common stock.

Combination with Interested Stockholders Statute

Sections 78.411 to 78.444 of the NRS, which apply to any Nevada corporation which has at least 200 stockholders of record and is publicly traded, including us, prohibits an “interested stockholder” from entering into specified types of business “combinations” with the Nevada corporation for two years, unless certain conditions are met. A “combination” includes:

any merger of the corporation or any subsidiary of the corporation with an “interested stockholder,” or any other entity, whether or not itself an “interested stockholder,” which is, or after and as a result of the merger would be, an affiliate or associate of an “interested stockholder;”

any sale, lease, exchange, mortgage, pledge, transfer, or other disposition in one transaction, or a series of transactions, to or with an “interested stockholder” or any affiliate or associate of an “interested stockholder,” of assets of the corporation or any subsidiary:

i.

having an aggregate market value equal to more than 5% of the aggregate market value of the corporation’s assets, determined on a consolidated basis;

ii.

having an aggregate market value equal to more than 5% of the aggregate market value of all outstanding voting shares of the corporation; or

iii.

representing more than 10% of the earning power or net income, determined on a consolidated basis, of the corporation; or

the issuance or transfer by the corporation or any subsidiary, of any shares of the corporation or any subsidiary to an “interested stockholder” or any affiliate or associate of an “interested stockholder,” having an aggregate market value equal to 5% or more of the aggregate market value of all of the outstanding voting shares of the corporation, except under the exercise of warrants or rights to purchase shares offered, or a dividend or distribution paid or made, pro rata to all stockholders of the resident domestic corporation;

26

the adoption of any plan, or proposal for the liquidation or dissolution of the corporation, under any agreement, arrangement or understanding, with the “interested stockholder,” or any affiliate or associate of the “interested stockholder;”

if any of the following actions occurs:

i.

a reclassification of the corporation’s securities, including, without limitation, any splitting of shares, share dividend, or other distribution of shares with respect to other shares, or any issuance of new shares in exchange for a proportionately greater number of old shares;

ii.

recapitalization of the corporation;

iv.

merger or consolidation of the corporation with any subsidiary; or

v.

any other transaction, whether or not with or into or otherwise involving the interested stockholder,

under any agreement, arrangement or understanding, whether or not in writing, with the interested stockholder or any affiliate or associate of the interested stockholder, which has the immediate and proximate effect of increasing the proportionate share of the outstanding shares of any class or series of voting shares or securities convertible into voting shares of the corporation or any subsidiary of the corporation which is beneficially owned by the interested stockholder or any affiliate or associate of the interested stockholder, except as a result of immaterial changes because of adjustments of fractional shares; or

any receipt by an “interested stockholder” or any affiliate or associate of an “interested stockholder,” except proportionately as a stockholder of the corporation, of the benefit of any loan, advance, guarantee, pledge or other financial assistance or any tax credit or other tax advantage provided by or through the corporation.

An “interested stockholder” is a person who is:

directly or indirectly, the beneficial owner of 10% or more of the voting power of the outstanding voting shares of the corporation; or

an affiliate or associate of the corporation, which at any time within two years immediately before the date in question was the beneficial owner, directly or indirectly, of 10% or more of the voting power of the then outstanding shares of the corporation.

A corporation to which the Combinations with Interested Stockholders Statute applies may not engage in a “combination” within two years after the interested stockholder first became an interested stockholder, unless the combination meets all of the requirements of the corporation’s articles of incorporation and (i) the combination or the transaction by which the person first became an interested stockholder is approved by the board of directors before the person first became an interested stockholder, or (ii)(a) the combination is approved by the board of directors and (b) at or after that time, the combination is approved at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of the stockholders representing at least 60% of the outstanding voting power of the corporation not beneficially owned by the interested stockholder or the affiliates or associates of the interested stockholder. If this approval is not obtained, the combination may be consummated after the two year period expires if either (i)(a) the combination or transaction by which the person first became an interested stockholder is approved by the board of directors before such person first became an interested stockholder, (b) the combination is approved by a majority of the outstanding voting power of the corporation not beneficially owned by the interested stockholder or any affiliate or associate of the interested stockholder, or (c) the combination otherwise meets the requirements of the Combination with Interested Stockholders statute. Alternatively, a combination with an interested stockholder engaged in more than 2 years after the date the person first became an interested stockholder may be permissible if the aggregate amount of cash and the market value of consideration other than cash to be received by holders of shares of common stock and holders of any other class or series of shares meets the minimum requirements set forth in the statue, and prior to the completion of the combination, except in limited circumstances, the interested stockholder has not become the beneficial owner of additional voting shares of the corporation.

PROSPECTUS
27

Acquisition of Controlling Interest Statute

In addition, Nevada’s “Acquisition of Controlling Interest Statute,” prohibits an acquiror, under certain circumstances, from voting shares of a target corporation’s stock after crossing certain threshold ownership percentages, unless the acquiror obtains the approval of the target corporation’s stockholders. Sections 78.378 to 78.3793 of the NRS only apply to Nevada corporations with at least 200 stockholders, including at least 100 record stockholders who are Nevada residents, that do business directly or indirectly in Nevada and whose articles of incorporation or bylaws in effect ten days following the acquisition of a controlling interest by an acquiror do not prohibit its application.

We do not intend to “do business” in Nevada within the meaning of the Acquisition of Controlling Interest Statute. Further, our Bylaws contain a specific opt out from the statute. Therefore, we believe it is unlikely that this statute will apply to us. The statute specifies three thresholds:

at least one-fifth but less than one-third;

at least one-third but less than a majority; and

a majority or more, of the outstanding voting power.

Once an acquiror crosses one of these thresholds, shares which it acquired in the transaction taking it over the threshold (or within 90 days preceding the date thereof) become “control shares” which could be deprived of the right to vote until a majority of the disinterested stockholders restore that right. A special stockholders’ meeting may be called at the request of the acquiror to consider the voting rights of the acquiror’s shares. If the acquiror requests a special meeting and gives an undertaking to pay the expenses of said meeting, then the meeting must take place no earlier than 30 days (unless the acquiror requests that the meeting be held sooner) and no more than 50 days (unless the acquiror agrees to a later date) after the delivery by the acquiror to the corporation of an information statement which sets forth the range of voting power that the acquiror has acquired or proposes to acquire and certain other information concerning the acquiror and the proposed control share acquisition.

If no such request for a stockholders’ meeting is made, consideration of the voting rights of the acquiror’s shares must be taken at the next special or annual stockholders’ meeting. If the stockholders fail to restore voting rights to the acquiror, or if the acquiror fails to timely deliver an information statement to the corporation, then the corporation may, if so provided in its articles of incorporation or bylaws, call certain of the acquiror’s shares for redemption at the average price paid for the control shares by the acquiror.

Our Charter and our Bylaws do not currently permit us to redeem an acquiror’s shares under these circumstances. The Acquisition of Controlling Interest Statute also provides that in the event the stockholders restore full voting rights to a holder of control shares that owns a majority of the voting stock, then all other stockholders who do not vote in favor of restoring voting rights to the control shares may demand payment for the “fair value” of their shares as determined by a court in dissenter’s rights proceeding pursuant to Chapter 92A of the NRS.

28

PLAN OFDISTRIBUTION

We may sell securities:

through underwriters;

through dealers;

through agents;

directly to purchasers; or

through a combination of any of these methods of sale.

We may also sell equity securities covered by this registration statement in an “at the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). Such offering may be made into an existing trading market for such securities in transactions at other than a fixed price, either:

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; and/or

to or through a market maker other than on The Nasdaq Capital Market or such other securities exchanges or quotation or trading services.

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act, and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis.

The distribution of the securities may be effected from time to time in one or more transactions:

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

at market prices prevailing at the time of sale;

at prices related to such prevailing market prices; or

at negotiated prices.

Each prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

The prospectus supplement with respect to the securities of a particular series will describe the terms of the offering of the securities, including the following:

the name of the agent or any underwriters;

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

any discounts and commissions to be allowed or re-allowed or paid to the agent or underwriters;

all other items constituting underwriting compensation;

29

any discounts and commissions to be allowed or re-allowed or paid to dealers; and

any exchanges on which the securities will be listed.

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

If a dealer is utilized in the sale of the securities in respect of which this prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

Remarketing firms, agents, underwriters, dealers and other persons may be entitled under agreements which they may enter into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

the purchase by an institution of the securities covered under that contract shall not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and

if the securities are also being sold to underwriters acting as principals for their own account, the underwriters shall have purchased such securities not sold for delayed delivery. The underwriters and other persons acting as our agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

Certain agents, underwriters and dealers, and their associates and affiliates may be customers of, have borrowing relationships with, engage in other transactions with, and/or perform services, including investment banking services, for us or one or more of our respective affiliates in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. The applicable prospectus supplement may provide that the original issue date for your securities may be more than two scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the second business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle more than two scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

The securities may be new issues of securities and may have no established trading market. The securities may or may not be listed on a national securities exchange. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights selected information about us and this offering and does not contain all of the information that you should consider before investing in our securities. Before investing in our common stock, you should carefully read the information contained and incorporated by reference in this prospectus supplement, the accompanying prospectus, any related free-writing prospectus that we have authorized for use in connection with this offering and the documents incorporated by reference herein or therein, including the sections titled Risk Factors,Cautionary Note Regarding Forward-Looking Statements and the financial statements and accompanying notes.

Business Overview

We are a clinical-stage biopharmaceutical company pioneering neuroscience to deliver first-in-class therapies for psychiatric and neurological disorders. Five of our six clinical-stage product candidates – fasedienol (PH94B), itruvone (PH10), PH15, PH80 and PH284 – belong to a new class of drugs known as pherines, which have the potential to rapidly deliver meaningful efficacy with a differentiated safety profile. Pherines are investigational neuroactive nasal sprays with innovative proposed mechanisms of action that activate chemosensory neurons in the nasal passages to impact fundamental neural circuits in the brain without the need for systemic absorption or binding to receptors in the brain. Our sixth clinical-stage product candidate, AV-101, is an investigational oral drug candidate with the potential to inhibit, but not block, NMDA receptor activity.

We are passionate about transforming what is possible in the treatment of anxiety, depression, and other neuroscience disorders.

Our Clinical-Stage Neuroscience Product Candidates

Fasedienol Nasal Spray for Social Anxiety Disorder (SAD)

Fasedienol (PH94B) is an odorless, tasteless synthetic investigational pherine nasal spray from the androstane family in Phase 3 clinical development for the acute treatment of anxiety for adults with SAD. When administered intranasally in microgram-level doses, fasedienol activates receptors of peripheral nasal chemosensory neurons connected to subsets of neurons in the olfactory bulbs that, in turn, connect to neurons in the limbic amygdala involved in the pathophysiology of SAD, and potentially other anxiety and mood disorders. Fasedienol is pharmacologically active without requiring apparent systemic absorption or direct activity on neurons in the brain to achieve its rapid-onset and short-duration anxiolytic effects. We believe fasedienol has the potential to achieve these effects with significantly reduced risks of side effects and other safety concerns, such as potential drug-drug interactions, abuse, misuse, and addiction, associated with certain other systemic pharmaceuticals that act directly on neurons in the brain and are sometimes prescribed for anxiety disorders.

The U.S. Food and Drug Administration (the FDA) has granted Fast Track designation for the development of fasedienol as a potential treatment for SAD.

Fasedienol PALISADE Phase 3 Program in SAD

Given how fasedienol’s rapid-onset mechanism of action (MOA) is differentiated from all FDA-approved anxiety drugs, our primary target indication for fasedienol is the acute treatment of anxiety in adults with SAD.  Currently, there is no FDA-approved drug therapy for the acute treatment of SAD.  For that acute indication, we have aligned with the FDA that the Subjective Units of Distress Scale (SUDS) is an appropriate primary efficacy endpoint because it provides a measure of anxiety on a minute-by-minute basis immediately related to the specific stressor. We believe utilizing a simulated anxiety-provoking public speaking challenge study design provides the most appropriate and efficient path for the Phase 3 clinical development of fasedienol’s potential to become the first FDA-approved acute treatment of anxiety for adults with SAD. Our PALISADE Phase 3 Program currently includes four randomized, double-blind, placebo-controlled, Phase 3 clinical trials designed to evaluate the efficacy, safety, and tolerability of a single dose of fasedienol to relieve anxiety symptoms in adult patients with SAD during a simulated, anxiety-provoking public speaking challenge in a clinical setting, as measured using the patient-reported SUDS, two of which Phase 3 trials (PALISADE-1 and PALISADE-2) have been concluded and two of which Phase 3 trials (PALISADE-3 and PALISADE-4) will be initiated in 2024, each with open-label extension. Our PALISADE Phase 3 Program also includes an open-label safety study concluded in 2022 (PALISADE OLS), a Phase 2 repeat dose study to be initiated in 2024 (Repeat Dose Study), two standard preclinical studies to be initiated in 2024, and a small human factor study planned to be initiated in 2025. 

S-5

In early August 2023, we received and reported positive topline results from our PALISADE-2 Phase 3 trial of fasedienol in SAD based on the 141 subjects who completed the trial. Our PALISADE-2 Phase 3 trial met its primary efficacy endpoint, the difference in mean SUDS scores during the public speaking challenge at baseline (Visit 2) and treatment (Visit 3) for subjects treated with fasedienol versus placebo at Visit 3.  Fasedienol-treated patients demonstrated a greater mean change from baseline (least-squares (LS) mean = -13.8) compared to placebo (LS mean = -8.0), for a statistically significant, and we believe clinically relevant, difference between groups of -5.8 (p=0.015).  The trial also met its secondary endpoint, demonstrating a statistically significant difference in the proportion of clinician-assessed responders between fasedienol and placebo as measured by the Clinical Global Impressions – Improvement (CGI-I) scale.  Responders were identified as those who were rated ‘very much less anxious’ or ‘much less anxious’ and 37.7% of fasedienol-treated patients were rated as responders, as compared to 21.4% of those treated with placebo (p=0.033). The trial also met the important exploratory endpoint of the difference in the proportion of patient-assessed responders between fasedienol and placebo as measured by the Patient’s Global Impression of Change (PGI-C). Responders were identified as those who self-rated ‘very much less anxious’ or ‘much less anxious’ and 40.6% of fasedienol-treated patients were rated as responders, as compared to 18.6% of those treated with placebo (p=0.003). In addition, our PALISADE-2 trial also met the exploratory endpoint of the difference in the proportion of patients in each treatment group with a 20-point or greater improvement in patient-assessed SUDS score from baseline (Visit 2) to treatment (Visit 3). Of the fasedienol-treated patients, 35.7% demonstrated this statistically significant and clinically meaningful improvement in SUDS score, as compared to 18.6% in the placebo-treated group (p=0.020). Fasedienol was observed to be well-tolerated with no serious adverse events, and the treatment-emergent adverse event (TEAE) profiles were comparable between fasedienol and placebo. Overall, no TEAE, except for pyrexia in the placebo group (2.49%), was more prevalent than 2.0%. 

To complement the positive topline results from PALISADE-2, we are preparing to launch PALISADE-3 in the first half of 2024 and PALISADE-4 in the second half of 2024. Like PALISADE-2, both PALISADE-3 and PALISADE-4 will be multi-center, randomized, double-blind, placebo-controlled studies designed to evaluate the efficacy, safety, and tolerability of the acute administration of fasedienol to relieve anxiety symptoms in adult patients with SAD after a single dose of fasedienol during a simulated, anxiety-provoking public speaking challenge in a clinical setting, as measured using the patient-reported SUDS as the primary efficacy endpoint. In addition, both PALISADE-3 and PALISADE-4 will have an open-label extension for a period of up to 12 months. We believe either PALISADE-3 or PALISADE-4, if successful, together with PALISADE-2, may establish substantial evidence of effectiveness of fasedienol in support of a potential fasedienol NDA submission for the acute treatment of anxiety in adults with SAD with the FDA.

We are also planning to initiate the Repeat Dose Study in the second half of 2024. The Repeat Dose Study will be a multi-center, randomized, double-blind, placebo-controlled, clinical trial designed to evaluate repeated dosing of fasedienol in adult patients with SAD during a single simulated, anxiety-provoking public speaking challenge in a clinical setting. The Repeat Dose Study trial will consist of three different dosing arms, with an open-label extension for a period of up to 12 months.

The U.S. FDA has granted Fast Track designation for the investigation of fasedienol for the acute treatment of SAD.

Itruvone Nasal Spray for Major Depressive Disorder (MDD)

Itruvone (PH10) is an odorless, tasteless synthetic investigational neuroactive pherine nasal spray from the pregnane family with an innovative potential MOA that is fundamentally differentiated from the MOA of all currently approved treatments for depression disorders. Itruvone neuroactive nasal spray is administered at microgram-level doses and is designed to engage and activate chemosensory neurons in the nasal cavity, which are connected to neural circuits in the brain that produce antidepressant effects. Unlike all currently approved oral antidepressants (ADs) and rapid-onset intravenous and intranasal ketamine-based therapy, we believe itruvone does not require systemic absorption or direct activity on neurons in the brain to produce antidepressant effects without the side effects and safety concerns that may be associated with current antidepressant therapies.

We are currently preparing and planning for potential U.S. Phase 2B clinical development of itruvone for treatment of  MDD.  In a randomized, double-blind, placebo-controlled parallel design Phase 2A clinical trial of itruvone in MDD and published in the peer-reviewed British Journal of Pharmaceutical and Medical Research, at a 6.4 μg dose administered intranasally twice daily for eight weeks, PH10 significantly reduced depressive symptoms as early as one week based on the 17-item Hamilton Depression Scale (HAM-D-17) scores compared to placebo (p=0.022). Itruvone was well-tolerated and did not cause psychological side effects (such as dissociation or hallucinations) or other safety concerns that may be associated with other approved pharmacological therapies for MDD. The trial was sponsored by Pherin Pharmaceuticals (Pherin), now a wholly-owned subsidiary of Vistagen, and was conducted in Mexico. Positive data from our recent U.S. IND-enabling Phase 1 trial demonstrated that there were no reported treatment-related serious adverse events (SAEs) or discontinuations due to adverse events in the trial. Overall, itruvone was well-tolerated and continued to demonstrate a favorable safety profile consistent with all other itruvone trials completed to date.

The U.S. FDA has granted Fast Track designation for the investigation of itruvone for the treatment of MDD. 

PH80 Nasal Spray for Womens Health Disorders

PH80 is an odorless, tasteless synthetic investigational pherine nasal spray with a novel, rapid-onset potential MOA that is fundamentally differentiated from the MOA of all currently approved treatments for vasomotor symptoms (hot flashes) due to menopause, premenstrual dysphoric disorder (PMDD), and other women’s health disorders and migraine headaches. PH80 activates chemosensory neurons in the nasal cavity connected to neural circuits that modulate the basal forebrain associated with the control of body temperature.

S-6

PH80 for Moderate to Severe Vasomotor Symptoms (hot flashes) due to Menopause. We recently reported positive results from a previously unpublished exploratory randomized, double-blind, placebo-controlled Phase 2A study of PH80 for the acute treatment of vasomotor symptoms (hot flashes) due to menopause sponsored by Pherin, now our wholly-owned subsidiary. This Phase 2A study conducted in a real-world setting demonstrated a statistically significant reduction in the daily number of menopausal hot flashes compared to placebo at the end of the first week of treatment (p=<0.001), and the improvement was maintained through each treatment week until the end of the four-week treatment period (p=<0.001). PH80 treatment also significantly reduced the severity, disruption in function, and sweating related to hot flashes during the treatment period as compared with placebo. PH80 was well-tolerated with no serious adverse events (SAEs), and the adverse event profiles were comparable between PH80 and placebo. All 36 subjects completed four weeks of treatment and no subject discontinued participation in the study as a result of TEAEs.

PH80 for Premenstrual Dysphoric Disorder (PMDD). We also recently reported positive results from a previously unpublished exploratory randomized, double-blind, placebo-controlled Phase 2A clinical study of PH80 for acute management of the symptoms of PMDD, including negative mood and physical and behavioral symptoms, in subjects with a regular menstrual cycle and at least a one-year history of PMDD. This Phase 2A study was sponsored by Pherin, now our wholly-owned subsidiary, and demonstrated a statistically significant improvement versus placebo in acute management of the symptoms of PMDD, including negative mood and physical and behavioral symptoms. The initial study visit occurred after the onset of symptoms. All subjects were administered a placebo nasal spray, and those who showed no symptom improvement were eligible to return for the second visit, which occurred after the onset of symptoms during the next menstrual cycle. At the second study visit, subjects were randomized to receive a single dose of 0.9 µg PH80 nasal spray or placebo in the clinic. PH80 demonstrated statistically and clinically significant improvement versus placebo in symptoms of PMDD using the subject-rated Penn Daily Symptom Report (DSR) as early as Day 4 and continuing to Day 6 (p=0.008). PH80 also demonstrated statistically and clinically significant improvement versus placebo at Day 6 on the clinician-rated Premenstrual Tension Scale (PMTS) total score (p=0.006). PH80 was well-tolerated with no SAEs. The most common TEAE was headache, reported by 17% in the placebo group and 7% in the PH80 group. No other TEAE occurred more than once per subject.

We are preparing to conduct certain nonclinical studies during the 2024 calendar year necessary to submit our U.S. IND for potential Phase 2B clinical development of PH80 in the U.S. for one or more women’s health indications.

PH15 Nasal Spray for Cognitive and Psychomotor Performance and Improvement

PH15 is an odorless, tasteless synthetic investigational pherine nasal spray with a novel, rapid-onset potential MOA that is fundamentally differentiated from the MOA of all currently approved treatments to improve cognitive impairment caused by mental fatigue and potentially other disorders. We believe intranasal PH15 has the potential to improve cognitive and psychomotor performance and improvement of reaction time in individuals with mental fatigue. We are currently evaluating the potential path forward for PH15, including an assessment of completed studies and studies we believe are necessary to submit a U.S. IND for potential further Phase 2 clinical development of PH15 in the U.S., including the appropriate indication for demonstrating improvement of cognitive function.

PH284 Nasal Spray for Cachexia

PH284 is an odorless, tasteless synthetic investigational pherine nasal spray with a novel, rapid-onset potential MOA that is fundamentally differentiated from the MOA of all currently approved treatments for the loss of appetite associated with chronic disorders such as cancer. Cachexia is a serious but under-recognized consequence of many chronic diseases with body mass loss of >10% and a prevalence of 5 to 15 %. We believe PH284 may have therapeutic potential for improving subjective feelings of hunger in patients with cachexia.  We are currently evaluating the potential path forward for PH284, including assessment of completed studies and studies we believe are necessary to submit a U.S. IND for potential further Phase 2 clinical development of PH15 for the treatment of cachexia, including the appropriate patient populations for demonstrating an increase in appetite and weight gain.

AV-101for Neurological Disorders

AV-101 (4-Cl-KYN) is a novel, oral prodrug that targets the NMDAR (N-methyl-D-aspartate receptor), an ionotropic glutamate receptor in the brain. Based on observations and findings from preclinical studies, we believe AV-101 has the potential to become a new oral treatment alternative for multiple neuroscience disorders, including levodopa-induced dyskinesia and neuropathic pain among others. We are currently assessing a path forward for potential Phase 2A clinical development of AV-101, either on our own or with collaborators, as a treatment for levodopa-induced dyskinesia associated with Parkinson’s disease therapy and possibly one or more additional neurological disorders involving the NMDAR receptor.

The U.S. FDA has granted Fast Track designation for the investigation of AV-101 for the treatment of neuropathic pain and for the adjunctive treatment of MDD.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described below and in our Annual Report on Form10-Kfor the fiscal year ended March31, 2023 and our Quarterly Reports on Form10-Qfor the periods ended June30, 2023, September 30, 2023 and December 31, 2023 incorporated by reference into this prospectus supplement and the accompanying prospectus, any amendment or update thereto reflected in our subsequent filings with the SEC, any related free writing prospectus and all of the other information contained in this prospectus supplement, the accompanying prospectus, any related free writing prospectus and the documents incorporated by reference herein or therein, including our financial statements and related notes. If any of these risks is realized, our business, financial condition, results of operations and prospects could be materially and adversely affected. In that event, the trading price of our common stock could decline, and you could lose part or all of your investment. Additional risks and uncertainties that are not yet identified or that we currently believe to be immaterial may also materially harm our business, operating results and financial condition and could result in a complete loss of your investment.

Risks Relating to this Offering

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

The shares sold in this offering, if any, will be sold from time to time at various prices. However, we expect that the offering price of our common stock will be substantially higher than the net tangible book value per share of our outstanding common stock. After giving effect to the sale of shares of our common stock in the aggregate amount of $100,000,000 at an assumed offering price of $4.90 per share, the last sale price of our common stock on February 9, 2024 on The Nasdaq Capital Market, and after deducting commissions and estimated offering expenses, our as adjusted net tangible book value as of December 31, 2023 would have been approximately $220.0 million or approximately $4.64 per share. This represents an immediate increase in net tangible book value of approximately $0.10 per share to our existing stockholders and an immediate dilution in as adjusted net tangible book value of approximately $0.26 per share to purchasers of our common stock in this offering. See “Dilution” for more information.

In addition to this offering, subject to market conditions and other factors, we may pursue additional equity financings in the future, including future public offerings or future private placements of equity securities or securities convertible into or exchangeable for equity securities at prices that may be higher or lower than the price per share in this offering. Further, the exercise of outstanding options or warrants could result in further dilution to investors and any additional shares issued in connection with acquisitions, collaborations, licensing transactions or other similar transactions will result in dilution to investors. In addition, the market price of our common stock could fall as a result of resales of any of these shares of common stock due to an increased number of shares available for sale in the market.

The common stock offered hereby will be sold in at the market offerings, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and accordingly may experience different levels of dilution and different outcomes in their investment results. We will have discretion, subject to market demand and the terms of the Sales Agreement, to vary the timing, prices and number of shares sold in this offering. In addition, subject to the final determination by our board of directors or any restrictions we may place in any applicable placement notice, there is no minimum or maximum sales price for shares to be sold in this offering. Investors may experience a decline in the value of the shares they purchase in this offering as a result of sales made at prices lower than the prices they paid.

Sales of a substantial number of shares of our common stock, or the perception that such sales may occur, may adversely impact the price of our common stock.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception that such sales may occur, may adversely impact the price of our common stock, even if there is no relationship between such sales and the performance of our business. As of December 31, 2023, we had 27,025,209 shares of common stock outstanding, as well as outstanding options to purchase an aggregate of 729,500 shares of our common stock at a weighted average exercise price of $36.48 per share, and outstanding warrants to purchase up to an aggregate of 24,182,034 shares of our common stock at a weighted average exercise price of $6.24 per share. The exercise and/or conversion of such outstanding derivative securities may result in further dilution of your investment.

S-9

Our management will have broad discretion in the use of the net proceeds from this offering and may allocate such net proceeds in ways that you and other stockholders may not approve.

Our management will have broad discretion in the use of the net proceeds from this offering, including for any of the purposes described in the section titled “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. The failure of our management to use these funds effectively could harm our business. Pending their use, we may invest the net proceeds from this offering in short- and intermediate-term, interest-bearing obligations, investment-grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government. These investments may not yield a favorable return to our stockholders.

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.

Because we have no current plans to pay cash dividends on our common stock for the foreseeable future, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.

We intend to retain future earnings, if any, for future operations and expansion of our business and have no current plans to pay any cash dividends for the foreseeable future. The declaration, amount and payment of any future dividends on shares of common stock will be at the sole discretion of our Board of Directors. Our Board of Directors may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions, implications on the payment of dividends by us to our stockholders or by our subsidiaries to us and such other factors as our Board of Directors may deem relevant. In addition, our ability to pay dividends may be limited by covenants in connection with any indebtedness we or our subsidiaries may incur. As a result, you may not receive any return on an investment in our common stock unless you sell our common stock for a price greater than that which you paid for it.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. We currently have research coverage by four securities and industry analysts. If one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

We may be subject to securities litigation, class action and derivative lawsuits, which could result in substantial costs and could divert management attention away from other business concerns.

The market price of our common stock may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Even if the lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources from other business concerns, which could seriously harm our business. An adverse judgment could result in monetary damages, which could have a negative impact on our liquidity and financial condition.

The market price of our common stock may be adversely affected by market conditions affecting the stock markets in general, including price and trading fluctuations on Nasdaq.

Market conditions may result in volatility in the level of, and fluctuations in, market prices of stocks generally and, in turn, our common stock and sales of substantial amounts of our common stock in the market, in each case being unrelated or disproportionate to changes in our operating performance. A weak global economy or other circumstances, such as changes in tariffs and trade, could also contribute to extreme volatility of the markets, which may have an effect on the market price of our common stock.

S-10

USE OF PROCEEDS

We may issue and sell shares of our common stock having aggregate sales proceeds of up to $100,000,000 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 we will sell any shares under or fully utilize our Sales Agreement with Jefferies.

We intend to use the net proceeds from this offering to advance the clinical development of our product candidates and for working capital and other general corporate purposes. Pending other uses, we intend to invest our proceeds from this offering in short-term investments or hold them as cash. We cannot predict whether the proceeds invested will yield a favorable return. Our management will have broad discretion in the use of the net proceeds from this offering, and investors will be relying on the judgment of our management regarding the application of the net proceeds. 

S-11

DILUTION

Purchasers of our common offered by this prospectus supplement and the accompanying prospectus will suffer immediate and substantial dilution in the net tangible book value per share of common stock. Net tangible book value is total assets minus the sum of liabilities and intangible assets. Net tangible book value per share is net tangible book value divided by the total number of shares of common stock outstanding. As of December 31, 2023, our net tangible book value was approximately $122.7 million, or approximately $4.54 per share.

After giving effect to the assumed sale of 20,408,163 shares of common stock in the aggregate amount of $100,000,000 at an assumed public offering price of $4.90 per share, the last reported price of our common stock on The Nasdaq Capital Market on February 9, 2024, after deducting the underwriting discount and commissions, and estimated offering expenses payable by us, our pro forma net tangible book value as of December 31, 2023 would have been approximately $220.0 million or approximately $4.64 per share. This amount represents an immediate increase in net tangible book value of approximately $0.10 per share to existing stockholders and an immediate dilution in net tangible book value of approximately $0.26 per share to purchasers of our common stock in this offering.

The following table illustrates the dilution in net tangible book value per share to new investors:

Assumed Public offering price per share

     $4.90 

Net tangible book value per share as of December 31, 2023

 $4.54     

Increase in pro forma, net tangible book value per share after this offering

 $0.10     

Pro forma net tangible book value per share after this offering

     $4.64 

Dilution in pro forma net tangible book value per share to new investors in this offering

     $0.26 

The foregoing discussion and table do not take into account further dilution to new investors that could occur upon the exercise of outstanding options or warrants having a per share exercise price less than the assumed public offering price in this offering. To the extent that we raise additional capital through the sale of equity or convertible debt securities after this offering, the issuance of those securities could result in further dilution to our stockholders.

The above discussion and table are based on 27,025,209 shares of common stock outstanding as of December 31, 2023 and excludes the following securities:

24,182,034 shares of common stock that have been reserved for issuance upon exercise of outstanding warrants, with a weighted average exercise price of $6.24 per share;

729,500 shares of common stock reserved for issuance upon exercise of outstanding stock options under our 2019 Omnibus Equity Incentive Plan, as amended (the “2019 Plan”), with a weighted average exercise price of $36.48 per share;

552,295 shares of common stock reserved for future issuance in connection with future grants under the 2019 Plan; and

19,480 shares of common stock reserved for future issuance in connection with our 2019 Employee Stock Purchase Plan (the “ESPP”).

S-12

PLAN OF DISTRIBUTION

We have previously entered into the Sales Agreement with Jefferies, under which we may offer and sell shares of common stock from time to time through Jefferies acting as agent. Pursuant to this prospectus supplement, we may offer and sell up to $100,000,000 of our shares of common stock. Sales of our shares of common stock, if any, under this prospectus supplement and the accompanying base 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. Pursuant to recent amendments to Rule 15c6-1 of the Exchange Act, settlement for any securities offered under this prospectus supplement on or after May 28, 2024, may occur on the first business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We will pay Jefferies a commission up to 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 in an amount not to exceed $75,000, in addition to certain ongoing disbursements of its legal counsel, unless we and Jefferies otherwise agree. 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 $215,000. 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 as permitted therein.

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 is filed as an exhibit to the registration statement of which this prospectus supplement forms a part.

Jefferies and its affiliates may in the future provide various investment banking, commercial banking, financial advisory and other financial services for us and our affiliates, for which services they may in the future receive customary fees. In the course of its business, Jefferies may actively trade our securities for its own account or for the accounts of customers, and, accordingly, Jefferies may at any time hold long or short positions in such securities.

A prospectus supplement and the accompanying base prospectus in electronic format may be made available on a website maintained by Jefferies, and Jefferies may distribute the prospectus supplement and the accompanying prospectus electronically.

ITEM 15.INDEMNIFICATION OF OFFICERS AND DIRECTORS

Section 78.7502 of the NRS permits a corporation to indemnify any person who was, is or is threatened to be made a party in a completed, pending or threatened proceeding, whether civil, criminal, administrative or investigative (except an action by or in the right of the corporation), by reason of being or having been an officer, director, employee or agent of the corporation or serving in certain capacities at the request of the corporation. Indemnification may include attorneys' fees, judgments, fines and amounts paid in settlement. The person to be indemnified must have acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action, such person must have had no reasonable cause to believe his conduct was unlawful.

With respect to actions by or in the right of the corporation, indemnification may not be made for any claim, issue or matter as to which such a person has been finally adjudged by a court of competent jurisdiction to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action was brought or other court of competent jurisdiction determines upon application that in view of all circumstances the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.

Unless indemnification is ordered by a court, the determination to pay indemnification must be made by the stockholders, by a majority vote of a quorum of the Board of Directors who were not parties to the action, suit or proceeding, or in certain circumstances by independent legal counsel in a written opinion. Section 78.751 of the NRS permits the articles of incorporation or bylaws to provide for payment to an indemnified person of the expenses of defending an action as incurred upon receipt of an undertaking to repay the amount if it is ultimately determined by a court of competent jurisdiction that the person is not entitled to indemnification.

Section 78.7502 also provides that to the extent a director, officer, employee or agent has been successful on the merits or otherwise in the defense of any such action, he must be indemnified by the corporation against expenses, including attorneys' fees, actually and reasonably incurred in connection with the offering described in this registration statement, other than underwriting discounts and commissions, alldefense.

Item 15. Indemnification of Directors and Officers. 
Our amended and restated bylaws provideour Charter, entitled “Indemnification,” provides that we willshall indemnify, and shall advance or reimburse the reasonable expenses incurred in advance of final disposition of the proceeding of, any individual made a party to a proceeding because that individual is or was a director of the corporation to the full extent and under all circumstances permitted by applicable law. Article X of our Bylaws, entitled “Indemnification,” provides that we shall indemnify our directors officers and employeesofficers to the fullest extent permitted by the Nevada Revised Statutes (NRS).
If the NRS are amended to authorize corporate action further eliminating or limiting the personal liability of a director, then the liability of our directors will be eliminated or limited to the fullest extent permittednot prohibited by the NRS, as so amended. Our articlesexcept in the case of incorporation do not eliminate a director’s duty of care and, in appropriate circumstances, equitable remedies,proceedings initiated by such as injunctiveofficers or directors unless certain other forms of non-monetary relief, will remain available under the NRS. This provision also does not affect a director’s responsibilities under any other laws, such as the federal securities laws or other state or federal laws. Under our bylaws, wefactors are empowered to enter into indemnification agreements with our directors, officers and employees to purchase insurance on behalf of any person whom we are required or permitted to indemnify.
In addition to the indemnification required in our bylaws, we have entered into indemnification agreements with each of the individuals serving on our board of directors. These agreements provide for the indemnification of our directors to the fullest extent permitted by law. We believe that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors, officers and employees. We also maintain directors’ and officers’ liability insurance.
The limitation of liability and indemnification provisions in our bylaws may discourage stockholders from bringing a lawsuit against our directors and officers for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit us and our stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.
present.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and certain employees pursuant to the foregoing provisions, or otherwise, we have 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.

There is no pending litigation or proceeding naming any of our directors or officers as to which indemnification is being sought, nor are we aware of any pending or threatened litigation that may result in claims for indemnification.
