Key Highlights and Anticipated Milestones
Metabolic Dysfunction-Associated Steatohepatitis (MASH)
- Pemvidutide was granted Breakthrough Therapy Designation by the U.S. Food and Drug Administration (FDA) based on 24-week data from the IMPACT Phase 2b trial
- In August 2026, the Company announced the initiation of the global PERFORMA Phase 3 MASH trial, with 52-week data readout anticipated in 2029
- The PERFORMA trial is a Phase 3, Global, Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy, Safety, and Clinical Outcomes of Pemvidutide in Subjects with MASH
- The PERFORMA trial is a Phase 3, Global, Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy, Safety, and Clinical Outcomes of Pemvidutide in Subjects with MASH
Alcohol Use Disorder (AUD)
- In July 2026, the Company reported positive topline results from the RECLAIM Phase 2 trial of pemvidutide in AUD
- The RECLAIM trial evaluated the safety and efficacy of pemvidutide versus placebo in 100 patients with AUD over a 24-week treatment period
- Pemvidutide achieved a statistically significant and clinically meaningful reduction in heavy drinking days, the primary endpoint of the trial
- Important secondary endpoints were also met, including a 2-level reduction in WHO-risk drinking levels and zero heavy drinking days, both recognized by the FDA as registrational endpoints
- A generally favorable safety and tolerability profile was observed in the trial
- The Company plans to request an End-of-Phase 2 meeting with the FDA and engage with the European regulatory agencies to discuss a path forward in AUD
- The FDA granted Fast Track designation to pemvidutide for the treatment of AUD
Alcohol-associated Liver Disease (ALD)
- In July 2026, the Company completed patient enrollment in the RESTORE Phase 2 trial of pemvidutide in ALD
- The RESTORE trial is a 48-week study evaluating the safety and efficacy of pemvidutide versus placebo in approximately 120 patients with liver disease due to excessive alcohol consumption
- The trial enrolled patients with ALD and a history of chronic and heavy drinking at baseline
- To support future regulatory discussions, the Company has amended the trial protocol to more fully evaluate the liver benefits pemvidutide may provide after one year of treatment in the ALD population
- The primary endpoint, change from baseline in Liver Stiffness Measurement (LSM), will now be assessed hierarchically at Week 48 and then at Week 24

About Pemvidutide
Pemvidutide is an investigational novel 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 July 2026, the Company completed enrollment of the RESTORE Phase 2 trial in ALD.
