An investigational GLP-1 and glucagon receptor dual agonist peptide studied in preclinical liver models and clinical metabolic research.
Pemvidutide (ALT-801) is an investigational synthetic peptide engineered as a dual agonist of the glucagon-like peptide-1 (GLP-1) receptor and the glucagon receptor, under development by Altimmune. The dual mechanism is described in the literature as combining GLP-1-mediated appetite signaling with glucagon-mediated effects on energy expenditure and hepatic lipid metabolism.
It remains investigational and has been evaluated in preclinical models of steatohepatitis and in phase 2 clinical research in overweight and obesity populations.
Pemvidutide co-activates the GLP-1 and glucagon receptors, both class B GPCRs. Study reports describe GLP-1 receptor engagement with appetite and glycemic signaling, while glucagon-receptor activity is investigated for its proposed contribution to energy expenditure and to hepatic fat metabolism [1].
Researchers frame the dual-agonist design as intended to balance the two receptor activities within a single molecule.
In a translational mouse model of non-alcoholic steatohepatitis, investigators administered ALT-801 and reported effects on hepatic steatosis and related metabolic measures compared with controls [1].
In the 48-week, placebo-controlled phase 2 MOMENTUM trial, researchers randomized non-diabetic subjects with overweight or obesity to weekly pemvidutide (1.2, 1.8, or 2.4 mg) or placebo and reported mean body-weight changes and reductions in liver-fat measures across dose groups [2].
