Altimmune Class Action Lawsuit Overview
Faruqi & Faruqi, LLP, a distinguished national securities law firm, is currently investigating possible claims against Altimmune, Inc. (NASDAQ: ALT). Investors who acquired securities in the company between August 10, 2023, and June 25, 2025, are encouraged to assess their legal options before the impending lead plaintiff deadline on October 6, 2025.
The firm's inquiry follows alarming revelations concerning Altimmune's IMPACT Phase 2b MASH trial concerning Pemvidutide. On June 26, 2025, the company disclosed topline results that indicated a significant failure to meet statistical expectations regarding fibrosis reduction. Despite previous assertions of potential success, the trial results did not back these inflated claims, highlighting a concerning discrepancy between what was touted and the actual outcomes. The press release suggested a negative trend in the expected results, with the responses from the company indicating a lack of urgency or responsibility regarding the disappointing data.
As a consequence of this disclosure, Altimmune's stock plummeted from $7.71 to $3.61—a staggering decline of over 53% in a single trading day—a clear indication of investors' disappointment and diminishing confidence in the company's future prospects.
