Switching to Oral Weight Management After GLP-1 Therapy

This study is looking at two oral medications, orforglipron and phentermine, to see if they can help people maintain weight loss after stopping injectable GLP-1 (glucagon-like peptide-1) medications like semaglutide or tirzepatide. You might be able to join if you are between 18 and 80 years old, have a history of obesity (BMI ≥30 kg/m²), and have lost at least 10% of your body weight using a GLP-1 medication within the last 8 weeks. The main goal is to see how much your body weight changes after 6 months on one of these new medications. The study is currently unclear on its recruitment status and plans to enroll 60 participants.
