Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with overweight or obesity who have not been treated with GLP-1-based therapies or certain diabetes conditions.

Probably not a fit

Individuals with diabetes or prior GLP-1, GIP, or amylin analogue treatments may be less likely to benefit and may not meet eligibility.

What this trial studies

This Phase 3, randomized, double-blind trial compares daily oral Zenagamtide to a placebo in adults with overweight or obesity. Participants are assigned by chance to receive either Zenagamtide or placebo for a set period, and safety and weight loss outcomes are collected. Key eligibility includes adults 18+ without diabetes and without prior GLP-1 or related treatments. The study is led by Novo Nordisk A/S with sites in Alabama, and recruitment prioritizes participants who meet the weight criteria and have no diabetes. Results will inform whether Zenagamtide can be a safe and effective option for weight management.

Why it matters

Potential benefit: If successful, participants may experience weight loss and improved health markers related to weight management.

How similar studies have gone: Other GLP-1–based weight loss studies have shown benefit, but this exact Zenagamtide approach is being tested in a Phase 3 trial.
