Amgen Bets on Icelandic Genomics and Monthly Injections in High-Stakes Obesity Drug Race

Amgen is advancing its experimental obesity drug, maridebart cafraglutide (MariTide), into Phase 3 trials. The drug, developed using genomic data from Iceland, aims to compete with weekly injectables like semaglutide and tirzepatide. Phase 2 results showed up to 20% weight loss over 52 weeks. Amgen's approach differs by blocking the GIP receptor, contrasting with competitors' strategies. The global obesity drug market is projected to exceed $120 billion annually by 2030.
