Altimmune Announces Initiation of Phase 2b IMPACT Trial Evaluating the Efficacy and Safety of Pemvidutide in Non-Alcoholic Steatohepatitis (NASH)
- Altimmune has enrolled the first subject in the Phase 2b IMPACT trial for pemvidutide, a potential treatment for NASH. Results from a Phase 1b trial showed promising reductions in liver fat and inflammation markers, as well as weight loss. Top-line results from the Phase 2b trial are expected in Q1 2025.
- None.
GAITHERSBURG, Md., Aug. 01, 2023 (GLOBE NEWSWIRE) -- Altimmune, Inc. (Nasdaq: ALT), a clinical-stage biopharmaceutical company, today announced that it has enrolled the first subject in the Phase 2b IMPACT trial evaluating the efficacy and safety of pemvidutide in subjects with non-alcoholic steatohepatitis (NASH). Pemvidutide is a novel, investigational GLP-1/glucagon dual receptor agonist under development for the treatment of obesity and NASH.
This randomized, placebo-controlled biopsy-driven trial is being conducted at approximately 60 sites in the United States, with Dr. Stephen Harrison, Medical Director, Pinnacle Research, and Adjunct Professor of Medicine, Oxford University, serving as the Principal Investigator. The trial is expected to enroll approximately 190 subjects with and without diabetes randomized 1:2:2 to receive either 1.2 mg, 1.8 mg pemvidutide or placebo weekly for 48 weeks. The key efficacy endpoints are NASH resolution and fibrosis improvement at 24 weeks of treatment, with subjects followed for an additional 24 weeks to a total of 48 weeks for safety and biomarker responses. Top-line results are expected in Q1 2025.
Results from a blinded, 24-week Phase 1b trial of pemvidutide in subjects with non-alcoholic fatty liver disease (NAFLD) showed a greater than
“Initiation of the IMPACT Phase 2b trial represents an important milestone in the development of pemvidutide for NASH,” said Scott Harris, M.D., Chief Medical Officer of Altimmune. “We are encouraged by the robust reductions of liver fat, inflammatory markers, serum lipids and body weight in our Phase 1b trial and anti-fibrotic effects in preclinical studies of pemvidutide and are excited about the prospect of achieving impressive rates of NASH resolution and fibrosis improvement in our IMPACT trial.”
About Pemvidutide
Pemvidutide is a novel, investigational, peptide-based GLP-1/glucagon dual receptor agonist in development for the treatment of obesity and NASH. Activation of the GLP-1 and glucagon receptors is believed to mimic the complementary effects of diet and exercise on weight loss, with GLP-1 suppressing appetite and glucagon increasing energy expenditure. Glucagon is also recognized as having direct effects on hepatic fat metabolism, leading to rapid reductions in levels of liver fat. Pemvidutide incorporates the EuPortTM domain, a proprietary technology that increases its serum half-life for weekly dosing while likely slowing the entry of pemvidutide into the bloodstream, which may improve its tolerability.
