Altimmune Plans Phase 3 MASH Trial as Pemvidutide Gains Breakthrough Status

  • Altimmune plans to initiate a Phase 3 MASH trial for pemvidutide in 2026, following FDA Breakthrough Therapy Designation.
  • Pemvidutide showed statistically significant improvements in key non-invasive markers of fibrosis and inflammation in the IMPACT Phase 2b trial.
  • Altimmune raised $75 million in a registered direct offering in January 2026, bringing total cash and investments to $340 million as of February 28, 2026.
  • Topline data from the RECLAIM Phase 2 trial of pemvidutide in alcohol use disorder (AUD) is expected in the third quarter of 2026.

Altimmune's strategic focus on pemvidutide positions it to address critical unmet needs in serious liver diseases, particularly MASH. The company's recent financial strengthening and regulatory milestones underscore its commitment to advancing the compound through Phase 3 development. The biopharmaceutical industry is increasingly focused on innovative therapies for liver diseases, and Altimmune's progress could position it as a key player in this space.
