Brenipatide (INN , USAN ; developmental code name LY-3537031) is a dual glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP) receptor agonist which is under development for the treatment of alcoholism, bipolar disorder, asthma, smoking withdrawal, cardiovascular disorders, liver disorders, metabolic disorders, and obesity. [1] [2] It is taken by subcutaneous injection once per month. [1] [2] The drug has a longer elimination half-life than tirzepatide or retatrutide. [2] Brenipatide is under development by Eli Lilly and Company. [1] As of December 2025, it is in phase 3 clinical trials for alcoholism and bipolar disorder, phase 2 trials for asthma and smoking withdrawal, and phase 1 trials for cardiovascular disorders, liver disorders, metabolic disorders, and obesity.

Brenipatide is a once-monthly dual-acting peptide from Eli Lilly that targets GLP-1R and GIPR (Table 1) and is currently in a Phase 3 clinical trial for moderate-to-severe alcohol use disorder (NCT07219966). Although it has a single C20 diacid, it exhibits a longer half-life than tirzepatide and retatrutide, likely because of a backbone optimized for stability against enzymatic degradation through a Trp to αMe-Tyr substitution.
