Amgen registers two Phase 3 extension trials for obesity drug maridebart cafraglutide

Both studies extend earlier Phase 3 parent trials to track long-term weight loss and safety through week 48 and beyond.

Amgen posted two new Phase 3 extension trials this week, both recruiting participants who took maridebart cafraglutide (MariTide, AMG 133) in earlier studies.

  • "MARITIME-1-EXTENSION" (NCT07684235) is an extension of trial 20210181 (NCT06858839), following participants with obesity or overweight who continue or are re-randomized to different doses of maridebart cafraglutide.1 The study is estimated to enroll 3200 participants1 and its primary outcome tracks percent change in body weight from the parent trial's baseline through week 48 of the current trial, along with treatment-emergent and serious adverse events through 60 weeks.1
  • "MARITIME-2-EXTENSION" (NCT07684144) is a Phase 3 extension trial evaluating maridebart cafraglutide in participants with obesity or overweight who also have type 2 diabetes mellitus, extending trial 20210184 (NCT06858878).2 The study is estimated to enroll 950 participants2, with primary outcomes covering percent change in body weight from the parent trial's baseline and adverse event rates through 60 weeks.2
