Introduction to the Biohaven Class Action Lawsuit

The Biohaven class action lawsuit stands out in the ever-evolving landscape of securities litigation as a significant case that has captured the attention of investors and legal experts alike. This lawsuit, which targets Biohaven Ltd. (NYSE: BHVN), addresses allegations of misleading information that may have adversely affected shareholders. As we jump into the very complex nature of this case, it is essential to understand the broader context of securities litigation, the specific allegations against Biohaven, and the rights of investors involved.

Understanding Securities Litigation

Securities litigation represent a significant legal mechanism for investors who have suffered financial losses due to corporate malfeasance. These lawsuits typically arise when a company or its executives engage in deceptive practices that mislead investors about the company’s financial health or prospect.

The goal of such litigation is to hold the perpetrators accountable and secure compensation for the affected investors. Securities fraud encompasses a range of activities, including insider trading, false financial statements, and misleading disclosures, all of which can severely impact market integrity and investor confidence.

In a class action context, a group of investors collectively brings the lawsuit against the defendant, which could be a corporation or its executives. This collective approach is particularly powerful in the securities realm because it allows individual investors, who might not have the resources to pursue litigation on their own, to band together and seek justice.

The class action mechanism ensures that the legal process is efficient and that the interests of all affected investors are represented.

The complexity of securities fraud class action lawsuits requires plaintiffs to navigate a labyrinth of legal standards and procedural hurdles. One of the most significant challenges is surviving a motion to dismiss, a legal maneuver by the defendants to have the case thrown out before it reaches trial.

Understanding the nuances of securities class actions is crucial for any stakeholder involved, as it sets the stage for the strategic decisions that will follow.

Allegations in the Biohaven Class Action Lawsuit

Biohaven is a biopharmaceutical company that discovers, develops, and commercializes therapies for immunology, neuroscience, and oncology.  According to the complaint, Biohaven is developing, among other product candidates, troriluzole for the treatment of spinocerebellar ataxia (“SCA”), among other indications, as well as BHV-7000 for the treatment of bipolar disorder, among other indications.

The Biohaven class action lawsuit alleges that defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that:

  • Troriluzole’s regulatory prospects as a treatment for SCA, and/or the sufficiency of data that Biohaven submitted in support of troriluzole’s regulatory approval for this indication, were overstated;
  • BHV-7000’s efficacy and clinical prospects as a treatment for bipolar disorder were likewise overstated; and
  • all the above, once revealed, was likely to have a significant negative impact on Biohaven’s business and financial condition.

The Biohaven class action lawsuit further alleges that on July 27, 2023, Biohaven disclosed that the U.S. Food and Drug Administration (“FDA”) had rejected its troriluzole New Drug Application (“NDA”), refusing even to review the application because Biohaven’s Phase 3 SCA trial had failed to meet its primary endpoint.  On this news, the price of Biohaven stock fell nearly 23%.

Then, on March 3, 2025, the Biohaven class action lawsuit further alleges that Biohaven disclosed that recent data from a late-stage study of BHV-7000 in bipolar mania “did not statistically separate from the comparator on the Young Mania Rating Scale primary outcome measure.”  On this news, the price of Biohaven stock nearly 14%, according to the complaint

Thereafter, on April 25, 2025, multiple news reports emerged that, according to the European Medicines Agency, Biohaven had withdrawn its troriluzole Marketing Authorization Application in late March 2025, the Biohaven class action lawsuit further alleges.  On this news, the price of Biohaven stock fell more than 15%, according to the complaint.

Finally, the complaint further alleges that on May 14, 2025, Biohaven “accounced that the Division of Neurology 1 within FDA’s Office of Neuroscience informed Biohaven that they are extending the [Prescription Drug User Fee Act (‘PDUFA’)] date for the troriluzole . . . NDA for the treatment of . . . SCA by three months to provide time for a full review of Biohaven’s recent submissions related to information requests from the FDA.”

According to the Biohaven class action lawsuit, Biohaven further announced that “[t]he Division also informed Biohaven that it is currently planning to hold an advisory committee meeting to discuss the application, but no date has been scheduled.”  On this news, the price of Biohaven stock fell more than 19%, according to the complaint.

  3. Lead Plaintiff: In a class action, one or more individuals may be appointed as lead plaintiffs to represent the interests of the entire class. This role is crucial in guiding the litigation process.
