Vistagen Reports Fiscal Year 2026 First Quarter Financial Results and Corporate Update

Topline results of PALISADE-3 Phase 3 Trial of fasedienol for acute treatment of social anxiety disorder expected in the fourth quarter of 2025

PALISADE-4 Phase 3 Trial topline results expected in the first half of 2026

Vistagen continues to advance diverse intranasal pherine pipeline targeting treatments in psychiatry, women鈥檚 health, and cancer supportive care

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Vistagen (Nasdaq: VTGN), a late clinical-stage biopharmaceutical company pioneering neuroscience with nose-to-brain neurocircuitry to develop and commercialize a new class of intranasal product candidates called pherines, today reported financial results for its fiscal year 2026 first quarter ended June 30, 2025, and provided a corporate update.

鈥淲e had another productive quarter, advancing key programs across our pipeline,鈥� said Shawn Singh, President and Chief Executive Officer of Vistagen. 鈥淥ur lead program, fasedienol, for acute treatment of social anxiety disorder, continues to progress, with topline results from our PALISADE-3 Phase 3 trial anticipated later this year, and topline results from our PALISADE-4 Phase 3 trial expected in the first half of 2026. With no FDA-approved acute treatment, we remain optimistic about fasedienol鈥檚 potential to impact the lives of over 30 million U.S. adults affected by social anxiety disorder. As the PALISADE trials near completion, we鈥檙e encouraged by growing support for our pherine platform, including itruvone for MDD and PH80 for hot flashes, from patients, clinicians, and key opinion leaders. With multiple near-term catalysts and a differentiated pipeline, we remain focused on delivering long-term impact for patients and value for stockholders.鈥�

Clinical-stage Neuroscience Product Candidates

Vistagen is developing a broad and diverse pipeline of five clinical-stage intranasal pherine product candidates spanning three key therapeutic areas: psychiatry, women鈥檚 health, and cancer supportive care.

Lead Program Highlights

Fasedienol for the Acute Treatment of Social Anxiety Disorder

• Vistagen鈥檚 lead clinical development program 鈥� the U.S. registration-directed PALISADE Program evaluating intranasal fasedienol for the acute treatment of Social Anxiety Disorder (SAD) 鈥� is moving closer to key milestones. The PALISADE-3 Phase 3 trial is expected to provide topline data in the fourth quarter of this year. Topline results for the PALISADE-4 Phase 3 trial are expected in the first half of 2026.
• Vistagen believes either PALISADE-3 or PALISADE-4, if successful, together with the positive results from PALISADE-2, may establish substantial evidence of the effectiveness of fasedienol in support of a potential New Drug Application (NDA) submission to the U.S. Food and Drug Administration (FDA) for the acute treatment of social anxiety in adults.
• There is no FDA-approved acute treatment for SAD, a serious and potentially life-threatening mental health disorder often associated with co-morbidities such as major depressive disorder and suicidal ideation. SAD affects more than 30 million U.S. adults, with rising prevalence, especially among those aged 18-22.

PH80 for Menopausal Hot Flashes and Other Women鈥檚 Health Indications

• Following positive results from exploratory Phase 2A studies in women鈥檚 health conditions, including vasomotor symptoms (hot flashes) due to menopause and premenstrual dysphoric disorder (PMDD), Vistagen is preparing its U.S. Investigational New Drug Application (IND) to facilitate further Phase 2 clinical development of PH80 for treatment of vasomotor symptoms (VMS), also known as hot flashes, due to menopause.
• An estimated 60% - 80% of menopausal women in the U.S. experience VMS, according to SWAN (Study of Women Across the Nation) and other published studies.

Itruvone for Major Depressive Disorder

• Following positive results from an exploratory Phase 2A, Vistagen is also planning for further Phase 2 development of itruvone for Major Depressive Disorder (MDD) under its U.S. IND in MDD.
• Depression is a serious medical condition and a global public health concern that can arise at any time during a person's life. According to the World Health Organization (WHO), depression is the leading cause of disability worldwide, affecting over 250 million people. Statistics reported by the U.S. National Institute of Mental Health (NIMH) indicate that approximately 21 million adults in the U.S., or approximately 8.4% of all adults in the U.S., experienced at least one major depressive episode in 2020.

Corporate Updates

In June, Vistagen announced the appointment of Elissa Cote as its Chief Corporate Development Officer, responsible for overseeing strategic, commercial, and business development functions.

Financial Results for Fiscal Year 2026 First Quarter Ended June 30, 2025

Research and development (R&D) expense

• R&D expense was $11.7 million for the three months ended June 30, 2025, as compared to $7.6 million for the three months ended June 30, 2024. The increase in R&D expense was primarily due to an increase in research, development, contract manufacturing expenses, and headcount related to the U.S. registration-directed PALISADE Program for fasedienol in SAD.

General and administrative (G&A) expense

• G&A expense was $4.4 million for the three months ended June 30, 2025, as compared to $4.6 million for the three months ended June 30, 2024.

Net loss

• Net loss was $15.1 million for the three months ended June 30, 2025, as compared to $10.7 million for the three months ended June 30, 2024.

Other financial highlights

• Cash, cash equivalents, and marketable securities were $63.2 million as of June 30, 2025.

About Pherines

Vistagen鈥檚 neuroscience pipeline currently consists of five investigational pherine product candidates, each with a novel mechanism of action (MOA) and positive clinical data in their targeted indications. Pherines activate peripheral receptors in human nasal chemosensory neurons and are designed to rapidly activate nose-to-brain neurocircuits, believed to modulate brain areas, without requiring systemic absorption or uptake into the brain to achieve desired therapeutic benefits and differentiated safety.

About Vistagen

Headquartered in South San Francisco, CA, Vistagen (Nasdaq: VTGN) is a late clinical-stage biopharmaceutical company leveraging a deep understanding of nose-to-brain neurocircuitry to develop and commercialize a new class of intranasal product candidates called pherines. Pherines specifically and selectively activate peripheral receptors on human nasal chemosensory neurons and are designed to rapidly trigger olfactory bulb-to-brain neurocircuits believed to regulate brain areas involved in behavior and autonomic nervous system activity. They are designed to achieve therapeutic benefits without requiring absorption into the blood or uptake into the brain, giving them the potential to be a safer alternative to other pharmacological options if successfully developed and approved.

Vistagen is passionate about developing transformative treatment options to improve the lives of individuals underserved by the current standard of care for multiple highly prevalent indications, including social anxiety disorder, major depressive disorder, and multiple women鈥檚 health conditions, including vasomotor symptoms (hot flashes) associated with menopause.
