Pomerantz Law Firm Files Class Action Against Biohaven Ltd. for Securities Fraud Allegations
In a significant legal development, Pomerantz LLP has announced the initiation of a class action lawsuit against Biohaven Ltd. and several key officers of the company, marking a pivotal moment for investors and stakeholders alike. The lawsuit has been officially filed in the United States District Court for the District of Connecticut. This legal action is on behalf of all individuals and entities, excluding the defendants, who acquired Biohaven securities between March 24, 2023, and May 14, 2025. The primary goal of the class action is to seek damages resulting from alleged violations of federal securities laws, particularly under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, in addition to Rule 10b-5.
The class action comes in response to what plaintiffs allege were misleading statements and materially false representations made by Biohaven's defendants regarding the company’s operational viability, prospects for regulatory approval, and overall financial health. Notably, the claims focus on Biohaven's development of its drug, troriluzole, aiming to treat spinocerebellar ataxia (SCA), and BHV-7000 for bipolar disorder among other indications.
The backdrop to this legal action unfolds with the disappointing results of a Phase 3 clinical trial for troriluzole that failed to meet its primary endpoint in May 2022. Following these results, investors allege that Biohaven's top officials continued to promote the drug's potential for commercialization based on selective data analysis, which ultimately misled investors about its actual viability and regulatory prospects. Furthermore, it is claimed that Biohaven made exaggerated claims regarding BHV-7000's efficacy, fostering a misleading narrative about its potential benefits prior to ultimately disappointing trial results.
In May 2023, the company submitted a New Drug Application (NDA) for troriluzole, which investors anticipated would reinvigorate interest in Biohaven. However, the FDA subsequently rejected this submission on July 27, 2023, citing previous trial failures as the core reason for their decision. Following this announcement, Biohaven saw a staggering 22.61% decrease in its stock price, plummeting $5.38 to close trades at $18.42 per share.
The tide turned further against the company as they continued to face setbacks in their pursuit of regulatory approval. In December 2024, Biohaven attempted to resubmit its NDA based on new data, but subsequent reports in March 2025 regarding clinical trials revealed that BHV-7000 did not deliver statistically significant results, leading to another sharp decline in share price.
The plaintiffs of the class action are encouraged to act swiftly. Investors who acquired Biohaven shares within the specified class period have until September 12, 2025, to apply for lead plaintiff status. Pomerantz LLP has provided resources on their website where interested parties can review the filed complaints and the details of the class action.
Pomerantz LLP, renowned for its expertise in corporate and securities class actions, has a rich legacy dating back over 85 years, fighting for the rights of those affected by securities fraud. Investors and stakeholders are thus drawn to monitor the progression of this case closely, not only for potential recovery of losses but also for its broader implications on the pharmaceutical industry and securities law. This case is not only a legal matter but serves as a wake-up call for corporate transparency in the burgeoning biopharmaceutical field, urging companies to uphold their obligations with stakeholders regarding the claims they make about their products.
