Summary

This study tests whether tirzepatide, a once-weekly injection, helps teenagers with obesity or overweight (with related health issues) lose weight. About 160 teens will receive either tirzepatide or a placebo for 72 weeks, alongside lifestyle advice. The main goal is to see if body mass index (BMI) changes, with additional checks on weight, waist size, and quality of life.

What this could lead to
If successful, this could offer a new weight-loss option for teens with obesity or weight-related health problems.
