Core Viewpoint - Altimmune, Inc. is set to present topline data from its IMPACT Phase 2b trial evaluating pemvidutide for treating metabolic dysfunction-associated steatohepatitis (MASH) on June 26, 2025 [1][2]. Group 1: Company Overview - Altimmune is a late clinical-stage biopharmaceutical company focused on developing novel peptide-based therapeutics for liver and cardiometabolic diseases [5]. - The company's lead program, pemvidutide, is a GLP-1/glucagon dual receptor agonist aimed at treating MASH, obesity, Alcohol Use Disorder (AUD), and Alcohol-associated Liver Disease (ALD) [5]. Group 2: IMPACT Study Details - The IMPACT trial enrolled 212 patients with biopsy-confirmed MASH and fibrosis stages F2/F3, randomized to receive either weekly subcutaneous pemvidutide at doses of 1.2 mg and 1.8 mg or placebo for 24 weeks [3]. - Key efficacy endpoints include MASH resolution or fibrosis improvement at 24 weeks, with secondary endpoints focusing on weight loss and non-invasive tests [3]. - A total of 48 weeks of treatment is planned, with final readout expected in Q4 2025 [3]. Group 3: Pemvidutide Characteristics - Pemvidutide is an investigational peptide-based dual receptor agonist that mimics the effects of diet and exercise on weight loss, suppressing appetite and increasing energy expenditure [4]. - Clinical trials have shown significant MASH resolution, liver fibrosis improvement, and weight loss, along with reductions in liver fat content, triglycerides, LDL cholesterol, and blood pressure [4]. - The U.S. FDA has granted Fast Track designation to pemvidutide for MASH treatment, with ongoing trials for AUD and ALD [4].
