Company description

Altimmune, Inc. is a late clinical-stage biopharmaceutical company developing novel therapies for serious liver diseases. Our lead product candidate, pemvidutide (formerly known as 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”). We may also pursue additional indications for pemvidutide that leverage its differentiated clinical profile. Except where the context indicates otherwise, references to “we,” “us,” “our,” “Altimmune”, or the “Company” refer to the company and its subsidiaries. Pemvidutide We obtained pemvidutide as part of the acquisition Spitfire Pharma Inc., in July of 2019. Pemvidutide was designed as a MASH therapeutic based on the understanding that targeting both metabolic and liver-specific effects could lead to an improved and differentiated candidate. Early work provided compelling preclinical efficacy data obtained from a mouse model of MASH. Following a first-in-human clinical trial where we observed initial signs of weight loss and pronounced liver effects, we evaluated pemvidutide in participants with fatty liver disease, or metabolic-dysfunction associated liver disease (MASLD), where we observed robust reductions in liver fat content and weight loss. These results confirmed the earlier study and paved the way for the biopsy-driven IMPACT Phase 2b trial in MASH.
