Allegations

The lawsuit arose following Altimmune’s press release on June 26, 2025, announcing the topline results from the IMPACT Phase 2b MASH trial. Investors claim that prior to these disclosures, the company had consistently provided misleading and inflated expectations regarding trial outcomes. Notably, the results indicated a failure to achieve statistical significance in the primary analysis related to fibrosis reduction.

Altimmune attributed this outcome to the trial's early phase and projected better results in future phases. Following this release, the company's stock price plummeted dramatically from $7.71 per share on June 25 to $3.61 on June 26, marking a staggering 53.2% decline in a single day.
