Overview

Efinopegdutide (MK-6024) is an investigational dual GLP-1/glucagon receptor co-agonist studied by Merck, more recently focused on non-alcoholic fatty liver disease. It is a long-acting peptide conjugate 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 conjugate engineered for extended half-life

Primary research or clinical context: Investigational compound (Merck); studied in trials for non-alcoholic fatty liver disease and NASH — not authorized by Health Canada

From diabetes to liver disease

Efinopegdutide began as a candidate for type 2 diabetes and obesity before those indications were discontinued and development refocused on fatty liver disease. As a balanced dual agonist it engages both the GLP-1 and glucagon receptors, a mechanism reported to lower hepatic fat but also associated with gastrointestinal effects common to the class.

Regulatory context

Efinopegdutide has received Fast Track designation in the United States for NASH but remains investigational and is not authorized by Health Canada. This page describes its chemistry and program history for education only and makes no claim that it treats or cures liver disease, diabetes or obesity.
