Strategic Insights

— 1 min read

Altimmune investors who suffered losses after the company's failed trial may be eligible to participate in a class action lawsuit. According to the complaint, Altimmune's management team led investors to believe that the company's Pemvidutide treatment in the Treatment of MASH trial would achieve statistical significance in reducing fibrosis, but the actual results showed a higher-than-expected placebo response, leading to a significant decline in the company's stock price.

Key Takeaways:

  • The lawsuit was filed by Levi & Korsinsky, LLP on behalf of Altimmune investors who suffered losses between August 10, 2023, and June 25, 2025.
  • The complaint alleges that Altimmune's management team engaged in securities fraud by leading investors to believe that the company's Pemvidutide treatment would achieve statistical significance in reducing fibrosis.
  • The trial results showed a higher-than-expected placebo response, leading to a significant decline in the company's stock price, from $7.71 per share on June 25, 2025, to $3.61 per share on June 26, 2025, a decline of 53.2%.
  • The lawsuit seeks to recover losses on behalf of investors who were adversely affected by the alleged securities fraud.
  • The court has given investors until October 6, 2025, to request that the Court appoint them as lead plaintiff.
  • Levi & Korsinsky has a track record of winning high-stakes cases and has secured hundreds of millions of dollars for aggrieved shareholders.

Statistics:

  • 53.2% decline in Altimmune's stock price on June 26, 2025, from a closing market price of $7.71 per share on June 25, 2025.
  • June 25, 2025, to June 26, 2025, is two days, but the 53.2% loss happened in a one-day span.
