SOLENO THERAPEUTICS, INC. CLASS ACTION LAWSUIT - COMPLAINT ALLEGATION SUMMARY:
Soleno is a pharmaceutical company focused on developing therapies for rare diseases and is headquartered in Redwood City, California. At the time of the filing of the complaint, Soleno's only commercial product was diazoxide choline extended-release tablets (DCCR) for the treatment of hyperphagia in individuals afflicted with Prader-Willi syndrome (PWS).

The complaint alleges that, throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about Soleno's business and operations. Specifically, Defendants misrepresented and/or failed to disclose that: (1) the Soleno Phase 3 clinical trial program for DCCR had systematically downplayed, misrepresented, and/or concealed significant evidence of safety concerns potentially related to the administration of DCCR, including issues related to excess fluid retention in clinical trial participants; (2) as a result, the administration of DCCR to treat hyperphagia in individuals with PWS posed materially greater safety risks than disclosed by Soleno or its executives; (3) consequently, DCCR had materially lower commercial viability and undisclosed risks related to the likelihood of significant and widespread adverse events after its commercial launch, including risks related to patient discontinuation rates, lower patient adoption, prescriber reluctance, adverse regulatory action, and potential reputational and legal fallout; and (4) as a result of the foregoing, Defendants' statements about the company's business, operations, and prospects were materially false and misleading at all relevant times.

Why did Soleno's Stock Drop?
On November 4, 2025, Soleno reported its financial results for its third fiscal quarter ended September 30, 2025. The company also revealed that a report issued by Scorpion Capital, LLC on August 15, 2025, had purportedly caused a "disruption" in DCCR's launch trajectory and concerns within the PWS community, with a lower number of patient start forms and increased discontinuations beginning after the report's publication. The Scorpion Report had, among other things, revealed significant issues with Soleno's Phase 3 clinical trial program for DCCR for the treatment of hyperphagia in individuals afflicted with PWS. On this news, the price of Soleno stock declined over 26%.
