Class
GLP-1 / glucagon receptor dual agonist (peptide)
Function
Once-weekly dual GLP-1 and glucagon receptor agonist studied for effects on body weight and liver fat
Context
Investigational compound (Altimmune); studied in trials for obesity and metabolic dysfunction-associated steatohepatitis — not authorized by Health Canada

Engineered to mimic the complementary effects of GLP-1 and glucagon without dose titration in reported protocols.

Also known as: ALT-801

Part of the Metabolic & GLP-1 peptides cluster

Overview

Pemvidutide (ALT-801) is an investigational dual GLP-1/glucagon receptor agonist developed by Altimmune and studied in clinical trials for obesity and MASH. It illustrates how a lipidated peptide can be designed for once-weekly dosing. It is not authorized by Health Canada, and this page is educational only.

Source & context

Biological / chemical source: Synthetic peptide with a lipid moiety engineered for weekly subcutaneous dosing

Primary research or clinical context: Investigational compound (Altimmune); studied in trials for obesity and metabolic dysfunction-associated steatohepatitis — not authorized by Health Canada

Design and dosing

Pemvidutide is a lipidated peptide that activates both the GLP-1 and glucagon receptors. In the developer's framework, GLP-1 activity supports appetite and glucose signalling while glucagon activity is associated with energy expenditure and hepatic lipid handling. The lipid moiety extends its half-life to support once-weekly subcutaneous administration in reported trials.

Research and regulatory status

Pemvidutide has been evaluated in phase 2 obesity and liver trials. It remains investigational and is not authorized by Health Canada. This educational summary describes its mechanism and development history without asserting any therapeutic benefit; decisions about metabolic health belong with a licensed clinician.
