About ALT
Altimmune, Inc. is a late clinical-stage biopharmaceutical company. The Company is developing novel therapies for serious liver diseases. Its lead product candidate, pemvidutide (formerly ALT-801), is a balanced 1:1 glucagon/GLP-1 dual receptor agonist 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, including reductions in liver fat, inflammation and fibrosis, whereas the activation of GLP-1 receptors mediates suppression of appetite and reduction of cravings as well as metabolic effects such as weight loss. It has completed Phase II development of pemvidutide. It also develops and commercializes surfactant-functionalized (EuPort domain) incretin-based peptide therapeutics, including (GLP-1-glucagon)/oxyntomodulin, and variants.
