Purpose

This was a study of tirzepatide in participants with obesity or overweight. The main purpose was to learn more about how tirzepatide maintained body weight loss. The study had two phases: a lead-in phase in which all participants took tirzepatide and a treatment phase in which participants either continued tirzepatide or switched to placebo. The study lasted about 2 years (25 visits).
