Background to the Altimmune Investigation

Altimmune is a clinical stage biopharmaceutical company that focuses on developing treatments for obesity, metabolic, and liver diseases.

The Altimmune class action lawsuit alleges that defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (i) defendants created the false impression that they possessed reliable information pertaining to the results of Altimmune’s IMPACT Phase 2b metabolic associated steatohepatitis (“MASH”) trial; (ii) Altimmune failed to meet an important statistical significance marker relating to the fibrosis reduction primary endpoint; and (iii) Altimmune concealed higher responses in the placebo group, which defendants knew or should have known would negatively impact the IMPACT Phase 2b MASH trial’s topline results.

ALTIMMUNE INVESTIGATION

The Altimmune class action lawsuit further alleges that on June 26, 2025, Altimmune announced topline results from the IMPACT Phase 2b Trial of Pemvidutide in the Treatment of MASH and disclosed that “[a]lthough we saw positive trends in fibrosis improvement, statistical significant was not achieved on this endpoint.”

On this news, the price of Altimmune stock fell more than 53%, according to the complaint.

Damage to Altimmune, Inc.

As a result of the foregoing, the company lost over half of its market capitalization and has been sued by its shareholders in federal court for violating the federal securities laws for which the Company will have to pay substantial compensation to defend, and may face a judgment or settlement in the millions of dollars which the Company will be required to pay. The investigation seeks to determine whether Altimmune’s executive officers and/or directors breached their fiduciary duties to the Company and its stockholders and/or committed other violations of state and/or federal law.
