Frequently asked questions about Pemvidutide

What is Pemvidutide used for?

Pemvidutide is an investigational peptide being developed for Metabolic Dysfunction-Associated Steatohepatitis (MASH), Alcohol Use Disorder (AUD), Alcohol-associated Liver Disease, and Nonalcoholic Steatohepatitis (NASH). It is currently in Phase 2 and Phase 3 clinical trials for these conditions.

What does Pemvidutide target?

Pemvidutide targets the GLP-1 and glucagon receptors (GLP-1/GCGR). It is a peptide that acts as an agonist at these receptors, which are involved in metabolic regulation. This dual targeting is being studied for its potential effects in MASH, NASH, and alcohol-related conditions.

Who makes Pemvidutide?

Pemvidutide is being developed by Altimmune, Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol ALT. The company is conducting clinical trials to evaluate the drug's safety and efficacy in multiple indications.

What phase is Pemvidutide in?

Pemvidutide is in Phase 2 and Phase 3 clinical development. It has a Phase 3 trial recruiting for MASH, and Phase 2 trials for alcohol-associated liver disease and alcohol use disorder. It is not FDA approved and remains investigational.

What clinical trials is Pemvidutide in?

Pemvidutide is being studied in several trials: NCT07795164 (Phase 3, MASH, recruiting), NCT07009860 (Phase 2, alcohol-associated liver disease, active), NCT06987513 (Phase 2, AUD, completed), and NCT05989711 (Phase 2, NASH, completed). These trials are primarily in the United States.

Is Pemvidutide the same as other drugs?

Pemvidutide is a distinct investigational drug with no alternative names provided. It is a peptide targeting GLP-1 and glucagon receptors, and it is being developed specifically by Altimmune for metabolic and alcohol-related liver conditions.
