The candidate supported monthly dosing with the longest half-life of any known amylin analog, 19 days. MET-233i had no safety indications and was well tolerated. The trial included 80 overweight or obese participants, with individual cases resulting in weight loss of up to 10.2%.

MET-233i displayed high tolerability and dose-linear pharmacokinetics when tested in both single and multiple ascending dose formats. The majority of adverse gastrointestinal events occurred in the first week and were mild and dose-dependent.

According to preliminary findings, it might make it practical to use its fully-biased GLP-1 RA candidate, MET-097i, in the first monthly GLP-1 + amylin combination therapy. Topline results from combination trials and an ongoing monotherapy study with MET-097i are anticipated in late 2025. Metsera, Inc. (NASDAQ:MTSR)’s HALO™ peptide stabilization platform supports the program.
