Details of the Allegations

The lawsuit alleges that throughout the class period, key executives of Altimmune misrepresented the efficacy of the company's IMPACT Phase 2b MASH trial. The firm claims that instead of providing reliable outcomes, Altimmune failed to report crucial data regarding the trial, particularly concerning the primary endpoint aimed at fibrosis reduction. The misleading information led many investors to believe that the trial would yield favorable results, masking the reality of the company’s failure to meet significant statistical benchmarks.

Once the actual data was made public, it triggered a wave of investor losses as the stock price was adversely affected. The firm asserts that Altimmune had touted unrealistic expectations during the trial while downplaying less favorable outcomes related to results seen in the placebo group. Consequently, those who were misled by these assertions have been given the chance to seek redress through the ongoing legal action.
