About Pemvidutide
Pemvidutide is a novel, investigational peptide with balanced 1:1 glucagon/GLP-1 dual receptor agonist activity that has an effect on reducing liver fat, inflammation, and fibrosis, in development for the treatment of metabolic dysfunction-associated steatohepatitis (MASH), alcohol use disorder (AUD) and alcohol-associated liver disease (ALD). The activation of glucagon receptors results in direct effects on the liver, while GLP-1 receptors mediate metabolic effects such as appetite suppression and weight loss and are involved in pathways related to craving and reward.
The FDA granted Fast Track designations to pemvidutide for the treatment of MASH and AUD, as well as Breakthrough Therapy Designation for MASH. In
December 2025
, the Company announced topline 48-week data from the IMPACT Phase 2b trial in MASH. In
July 2026
, the PERFORMA Phase 3 trial, a global, randomized, double-blind, placebo-controlled, parallel-group study of pemvidutide in patients with MASH was initiated. In
July 2026
, the Company announced positive topline results from the RECLAIM Phase 2 trial in AUD. In
August 2026
, the Company announced completion of enrollment of the RESTORE Phase 2 trial in ALD.
