Lilly’s Tirzepatide Meets Trial Weight Loss Endpoints

Lilly says its tirzepatide achieved superior weight loss compared to placebo in the 72-week Phase 3 SURMOUNT-1 study. A company statement says the drug met both co-primary endpoints of superior mean percent change in body weight from baseline and a greater percentage of participants achieving body weight reductions of at least 5% compared to placebo. It says the study also achieved all secondary endpoints at 72 weeks.

Participants taking tirzepatide lost up to 52 pounds in the study and 63% of participants taking the 15 mg dose achieved at least 20% bodyweight reduction as a key secondary endpoint, Lilly says.

Tirzepatide is described as “a once-weekly glucose-dependent insulinotropic polypeptide receptor and glucagon-like peptide-1 receptor agonist that integrates the actions of both incretins into a single novel molecule.”
