Lawsuit Background: Bronstein, Gewirtz & Grossman LLC has filed a class action lawsuit against Soleno Therapeutics and its executives, seeking damages for investors who purchased securities between March 26, 2025, and November 4, 2025, highlighting investor concerns over potential risks associated with the company.
Safety Concerns Allegations: The complaint alleges that Soleno failed to disclose significant safety concerns related to its DCCR clinical trial, including issues of fluid retention in participants, indicating that the safety risks of the drug were severely underestimated, potentially leading to greater losses for investors.
Declining Commercial Viability: Due to undisclosed safety risks, the commercial viability of DCCR is questioned, which may result in higher patient discontinuation rates, reduced prescriber willingness, and potential regulatory actions, further impacting the company's market performance and investor confidence.
Investor Action Recommendations: Affected investors must apply to be lead plaintiffs by May 5, 2026, to participate in any recovery, with the law firm promising to charge fees only upon success, thereby reducing the financial burden on investors.

Reason

Wells Fargo lowered the firm's price target on Soleno Therapeutics to $110 from $114 and keeps an Overweight rating on the shares. While management's commentary on building out a pipeline plus LCM for Vykat XR and the CFO's retirement may remove some investors' near-term takeout thesis, the firm notes shares remain cheap relative to expected FY26 revenue and cash flow. Wells is a buyer at these levels.

Stock Price Plunge: Soleno Therapeutics experienced a sharp 27% drop in stock price on November 4, 2025, following the release of its third-quarter financial results, indicating significant investor harm due to major disruptions in the commercial launch of its lead drug, DCCR.
Undisclosed Safety Risks: The class action lawsuit alleges that Soleno systematically concealed critical safety evidence related to “excess fluid retention” in its Phase 3 clinical trials, leading to a 12% decline in stock value in August 2025, which undermined market confidence in the drug's commercial viability.
Decline in Patient Engagement: Management disclosed a decrease in patient start forms and an increase in discontinuations within the Prader-Willi syndrome community, correlating with a 19% drop in share value starting September 10, 2025, reflecting a significant loss of investor confidence in DCCR.

Securities Class Action Filed Against Soleno Therapeutics

18 hours agoGlobenewswire

Lawsuit Background: A securities class action has been filed against Soleno Therapeutics (NASDAQ: SLNO) to represent investors who purchased common stock between March 26 and November 4, 2025, highlighting significant investor concerns regarding the company's future prospects.
Stock Price Plunge: Following Soleno's disappointing report on DCCR (trademarked as VYKAT™ XR) on November 5, 2025, the stock price plummeted by 26% that day, indicating strong market skepticism about the safety and efficacy of its products.
Safety Concerns: The lawsuit alleges that Soleno concealed significant safety risks associated with DCCR, including issues of fluid retention in clinical trial participants, leading to a severe misjudgment of the drug's commercial viability by investors.
Market Trust Crisis: The trust crisis triggered by short seller Scorpion Capital's report led Soleno to acknowledge during its November 4, 2025 earnings call that its launch trajectory had been disrupted, resulting in fewer start forms and increased discontinuations for non-serious adverse events, further exacerbating investor panic.
