Investigation Commenced Against Supernus Pharmaceuticals, Inc.:
On March 21, 2025, Levi & Korsinsky, a leading securities law firm, announced that it has initiated an investigation into Supernus Pharmaceuticals, Inc. (Supernus) following the company’s disappointing Phase 2b study results for its lead drug candidate, SPN-820, for treatment-resistant depression. The investigation focuses on potential violations of federal securities laws.
Background:
Supernus Pharmaceuticals, Inc., headquartered in Rockville, Maryland, is a specialty pharmaceutical company focused on developing and commercializing products for central nervous system disorders. SPN-820 is a novel, investigational, oral, selective 5-HT1A agonist for the treatment of major depressive disorder (MDD) and treatment-resistant depression (TRD).
February 19, 2025: Disappointing Clinical Trial Results:
On February 19, 2025, Supernus announced the failure of its Phase 2b study of SPN-820 for TRD to meet its primary endpoint. The study, which enrolled 158 patients, demonstrated no significant improvement in the efficacy of SPN-820 compared to placebo in reducing depressive symptoms. The company attributed the failure to a lack of statistical significance in the primary endpoint.
Investigation Details:
Levi & Korsinsky is investigating whether Supernus and certain of its executives or members of the board of directors failed to disclose material information to investors. Specifically, the investigation focuses on whether Supernus and certain executives and board members misrepresented or failed to disclose the risks and challenges associated with the development of SPN-820 for TRD, and whether they failed to disclose that the clinical trial results were not meeting expectations prior to the public disclosure on February 19, 2025.
Impact on Investors:
Following the announcement of the failed clinical trial, Supernus stock prices dropped significantly, causing substantial losses for investors. Those who purchased Supernus securities between November 1, 2022, and February 18, 2025, may be entitled to recover their losses through the investigation.
Impact on the Pharmaceutical Industry:
The announcement of the failed clinical trial for SPN-820 could have far-reaching consequences for the pharmaceutical industry as a whole. The failure of a clinical trial, particularly one for a promising drug candidate like SPN-820, can significantly impact investor confidence in the industry and individual companies. Additionally, it highlights the inherent risks and challenges involved in drug development and the importance of transparency in communicating those risks to investors.

The impact on investors is significant, with substantial losses following the drop in Supernus stock prices.
