Metsera, Inc. (NASDAQ:MTSR), a clinical-stage biotech based in New York, is emerging as an innovative player in obesity and metabolic disease treatments. The company develops next-generation injectable and oral hormone analog peptides designed for potency, scalability, and improved patient adherence.
In 2025, Metsera, Inc.’s lead candidate, MET-233i, an ultra-long-acting amylin analog, showed promising Phase 1 results, with patients achieving up to 8% body weight reduction over five weeks.
