Excluding Sales Tax
Investigational triple agonist (GLP‑1/GIP/glucagon). Phase 2 data show large, dose‑dependent weight loss and improvements in metabolic markers. Potential benefits include potent appetite reduction plus higher energy expenditure via glucagon signaling. Long‑term safety and outcomes are still under evaluation.

  • Retatrutide(LY3437943) Research & Chemical Profile

    Description

    Retatrutide (LY3437943) is an investigational, acylated peptide that acts as a triple agonist at the glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon (GCGR) receptors. This multi-receptor profile is designed to combine incretin-driven appetite and glycemic effects (GLP-1, GIP) with glucagon-mediated increases in energy expenditure and lipid mobilization. In a phase 2 obesity study, retatrutide produced substantial weight reduction over 48 weeks with dose-dependent effects.

    Primary Research Focus

    • Obesity and weight management: phase 2 trial reported mean weight reduction up to ~24% at 48 weeks at the highest dose in adults with obesity without diabetes.
    • Glycemic and metabolic effects: improvements in glycemic markers in early studies; ongoing evaluation versus active comparators.
    • Cardiometabolic biomarkers and liver fat: reports of reductions in triglycerides, apoC-III, and liver fat content in development program updates.
    • Mechanistic rationale: GLP-1/GIP promote satiety and insulinotropic effects; GCGR engagement may increase energy expenditure and fat oxidation.

     

    Safety / Limitations

    • Adverse events consistent with incretin/glucagon agonism: gastrointestinal events (nausea, vomiting, diarrhea) were common and dose-related in trials; dose titration was used to improve tolerability.
    • Transient heart rate increases and other class effects are being monitored; full long-term cardiovascular and hepatic safety remain under study.
    • Drug is investigational; phase 3 trials are ongoing. Safety and efficacy are not established for clinical use outside trials.
