LY3537031

Eli Lilly and Company · Phase 3 active Small molecule ✓ Verified May 2026

LY3537031 is a GLP-1/GIP receptor dual agonist Small molecule drug developed by Eli Lilly and Company. It is currently in Phase 3 development for Type 2 diabetes mellitus, Obesity or weight management. Also known as: Brenipatide.

LY3537031 is a GLP-1 and GIP receptor dual agonist that activates both incretin pathways to improve glucose control and promote weight loss.

LY3537031 is a compound studied in clinical trials, including those for asthma, renal impairment, and end stage renal disease. It is a dual agonist of glucagon-like peptide-1 (GLP-1) receptors and gastric inhibitory polypeptide (GIP) receptors, similar to brenipatide.

Likelihood of approval
61.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Big-pharma sponsor +3.0pp
    Eli Lilly and Company is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr

Mechanism of action

By simultaneously activating GLP-1 and GIP receptors, LY3537031 enhances insulin secretion in response to glucose, slows gastric emptying, and increases satiety. This dual mechanism produces greater glycemic control and weight reduction compared to single GLP-1 agonists. The drug is being developed as a once-weekly injectable for metabolic disorders.
