The Allegations: Robbins LLP is Investigating Allegations that Altimmune, Inc. (ALT) Misled Investors Regarding the Viability of its IMPACT Phase 2b MASH Trial

According to the complaint, during the class period, defendants repeatedly touted their positive expectations of the topline results of the Company's MASH trial. On June 26, 2025, Altimmune announced the results from its IMPACT Phase 2b MASH trial of Pemvidutide in the treatment of MASH. Specifically, the Company failed to achieve statistical significance in the trial due to a higher-than-expected placebo response. On this news, the price of Altimmune's common stock fell from $7.71 per share on June 25, 2025 to $3.61 per share on June 26, 25, or more than 53% in a single day.
