Class Action Lawsuit Against Altimmune: What You Need to Know

On September 19, 2025, Levi & Korsinsky, LLP announced a class action securities lawsuit targeting investors in Altimmune, Inc. (NASDAQ: ALT). This lawsuit aims to seek redress for investors who suffered losses due to alleged securities fraud occurring between August 10, 2023, and June 25, 2025.

Background

The lawsuit stems from a concerning situation that arose post the announcement of topline results from the IMPACT Phase 2b trial regarding Pemvidutide for the treatment of NASH (Non-Alcoholic Steatohepatitis). On June 26, 2025, Altimmune reported results that contradicted the inflated expectations portrayed by its executive team leading up to the announcement. While a positive trend was noted in fibrosis improvement, the results failed to achieve statistical significance, largely attributed to a higher than expected placebo response.

As a result of this disappointing information, Altimmune's stock price plummeted from $7.71 per share on June 25, 2025, to $3.61 per share the following day, marking a staggering decline of 53.2%. This dramatic fall left many investors questioning the integrity of the information previously provided by the company, leading to the institution of this law suit.

Who Can Join?

Please note that the deadline for filing your request to be appointed lead plaintiff is October 6, 2025.
