Investors Allege Securities Fraud in Vistagen Therapeutics' Drug Development Disclosures

Legal Action Against Vistagen Therapeutics: A Closer Look

In a significant development for investors, Levi & Korsinsky, LLP has initiated a class action lawsuit against Vistagen Therapeutics, Inc. (NASDAQ: VTGN), targeting claims of securities fraud related to the company's communications regarding its drug development trials. The lawsuit covers shareholders who purchased Vistagen securities between April 1, 2024, and December 16, 2025.

Background on Vistagen Therapeutics

Vistagen Therapeutics is a clinical-stage biopharmaceutical company that specializes in creating treatments for neuropsychiatric and neurological disorders. The company is particularly focused on a novel investigational pherine nasal spray, touted as a potential game-changer in treating social anxiety disorder—a condition affecting around 30 million adults in the U.S., representing a glaring unmet medical need.

Despite the substantial market opportunity, Vistagen's recent troubles have cast a shadow over its promising outlook. The company faced scrutiny after initiating a Phase 3 clinical trial, essential for obtaining potential FDA approval. Allegations surfaced claiming that Vistagen had made materially misleading statements about its trials, creating an impression of reassuring results based on previous outcomes.

The Allegations

The complaint accuses Vistagen of making optimistic claims about its Phase 3 clinical trial's success likelihood while supposedly concealing significant risks that could affect the trial's outcome. Specifically, they allegedly omitted the presence of elevated placebo responses and variability among trial sites, both issues raised during earlier studies. When results were finally made public in December 2025, they revealed that the trial had not met its primary endpoint, leading to a sharp decline in Vistagen's stock price. This unexpected downturn left investors who had relied on Vistagen's earlier reassurances facing considerable financial losses.

What Investors Should Know

For shareholders who acquired Vistagen shares during the specified class period, this lawsuit provides a possible avenue for recovering losses without any upfront costs. The legal team at Levi & Korsinsky has a strong track record, having recovered hundreds of millions of dollars for aggrieved shareholders over the past two decades. Given its ranking in ISS Securities Class Action Services’ Top 50 Report for seven consecutive years, the firm embodies considerable expertise in securities litigation.

Investors affected by the decline in Vistagen's stock value and those who purchased shares during the class period are encouraged to seek more information about their legal options. Contacting attorney Joseph E. Levi may provide potential claimants with insights into the next steps and eligibility for compensation.

While Vistagen as a company focuses on unmet medical needs within the anxiety disorder space, the unfolding legal situation may serve as a cautionary tale about the importance of transparency and risk disclosure in corporate communications. As the lawsuit proceeds, the developments will be crucial for stakeholders and the future of Vistagen Therapeutics.

Conclusion

The class action lawsuit spearheaded by Levi & Korsinsky underscores a critical juncture in the biotech industry's intersection with investor interests. As Vistagen Therapeutics navigates these allegations, it will be vital for the company to rebuild trust with its stakeholders and address the concerns brought to light through this ongoing legal matter.
