Details of the case:

According to the lawsuit, defendants throughout the Class Period created the false impression that they possessed reliable information pertaining to the results of Altimmune’s IMPACT Phase 2b MASH trial. In truth, Altimmune failed to meet an important statistical significance marker relating to the fibrosis reduction primary endpoint. Altimmune had consistently touted its inflated expectations for positive topline results from the IMPACT Phase 2b MASH trial, while concealing higher responses in the placebo group, which they knew or should have known would negatively impact the topline results. Altimmune’s IMPACT Phase 2b MASH trial results fell short of reality, as shown by Altimmune’s topline data, which show that the statistical significance was not achieved for the fibrosis reduction primary endpoint.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor’s ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
