Primary Endpoints

Percent change from baseline in body weight
Baseline (Day 0) to Week 64
Percent change from baseline in body weight at Week 28
Baseline (Week 0) through Week 28 (Day 197)

Evaluate the efficacy at Week 28 of four dose regimens of QW MET097 switching to QM compared to placebo.

Percent change from baseline in body weight at Week 28 (Day 197)
Baseline (Week 0) through Week 28 (Day 197)
Percent Change From Baseline in Body Weight at Week 28: Part A
Baseline (last non-missing measurement prior to the first dose), Week 28

Analysis was performed using mixed model for repeated measures (MMRM) with treatment group, visit, and treatment by visit interaction, sex, and baseline body weight as fixed effects using unstructured covariance. The analysis excluded weight measurements after protocol specified intercurrent events (ICEs) including permanent treatment discontinuation, non-compliance to treatment and lifestyle change.

(Part C) Percent change from baseline in body weight at Week 12 (Day 85).
Day 1 (Week 0) to Day 85 (Week 12)

Frequently asked questions about MET097

What is MET097?

MET097 is an investigational small molecule being developed by Metsera, Inc. (ticker MTSR) for the treatment of obesity, overweight, and obesity in people with type 2 diabetes. It is a metabolic therapy in clinical development and is also referred to as MET097 Injection.

What is MET097 used for?

MET097 is being studied for obesity, overweight, and obesity in diabetes. Clinical trials have enrolled adults with overweight or obesity, including a Phase 2 study in adults with obesity or overweight and type 2 diabetes. It is investigational and has not been approved for any use.

Who makes MET097?

MET097 is developed by Metsera, Inc., which trades under the ticker MTSR. Metsera is the sponsor of the clinical program evaluating MET097 in obesity and overweight, including a Phase 3 trial and Phase 2 trials.

What phase is MET097 in?

MET097 is in Phase 2 development, with a Phase 3 trial also underway. The Phase 3 study NCT07311850 is active but not recruiting, and Phase 2 studies include NCT06973720 and the completed NCT06897202. MET097 is investigational and has not been approved.

What clinical trials is MET097 in?

MET097 has been studied in four registered trials. NCT07311850 is a Phase 3 trial in overweight or obesity, NCT06973720 is a Phase 2b once-monthly study, NCT06897202 is a completed Phase 2 trial in obesity with type 2 diabetes, and NCT06857617 is a completed Phase 1 study.

Is MET097 the same as MET097 Injection?

Yes. MET097 Injection is another name for MET097, and the drug is also listed as (Part C) MET097. All of these names refer to the same investigational small molecule developed by Metsera, Inc. for obesity and overweight.
