Short answer

MariTide (maridebart cafraglutide) is Amgen's investigational obesity drug: an antibody that blocks the GIP receptor, joined to two GLP-1 agonist peptides. Unusually, it antagonises GIP where tirzepatide activates it, and it is being studied with monthly or less frequent injections. Phase 2 reported substantial weight loss with gastrointestinal side effects, especially early. Phase 3 (MARITIME) trials are ongoing; it is not approved.
