What Happened?

On August 15, 2025, activist investor organization Scorpion Capital LLC published a 415-page report regarding Soleno entitled โ€œRussian Roulette With Prader-Willi Children: How The Latest Rare-Disease Price-Gouging Scheme Fleeced the FDA, Parents, And Its Own Study Investigators With A Worthless, Toxic Drug.โ€ The report alleges a number of problems with the Companyโ€™s diazoxide choline tablet (โ€œDCCRโ€), including clinical trial conduct, safety and efficacy concerns, and patient reports of serious adverse reactions following its commercial launch.

On this news, the price of Soleno stock declined $9.27 per share, or 11.98%, over two trading days to close at $68.09 on August 18, 2025, thereby injuring investors.

Then, on September 10, 2025, Soleno filed a Form 8-K with the U.S. Securities and Exchange Commission disclosing that a patient had died after taking DCCR.

On this news, the price of Soleno stock declined $13.49 per share, or 19.21%, over two trading days to close at $56.72 on September 11, 2025, thereby further injuring investors.

Finally, on November 4, 2025, Soleno reported its third quarter 2025 financial results, revealing that the Scorpion Capital report had disrupted DCCRโ€™s launch trajectory and raised concerns within the Prader-Willi syndrome community, in part resulting in a lower number of patient start forms and increased discontinuations beginning after the reportโ€™s publication.

On this news, the price of Soleno stock declined $16.98 per share, or 26.59% to close at $46.87 on November 5, 2025, thereby further injuring investors.

What Is The Lawsuit About?

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Companyโ€™s business, operations, and prospects. Specifically, Defendants failed to disclose to investors 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; and (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, Defendantsโ€™ positive statements about the Companyโ€™s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
