About Obesity Treatment
Medical treatment of obesity and severe overweight conditions.
Research Evidence
Phase 3 TRIUMPH-4 trial (Dec 2025) showed 28.7% weight loss at 68 weeks, with average loss of 71 lbs. Also showed significant osteoarthritis pain relief, reduced cardiovascular risk markers, and 14 mmHg blood pressure reduction. Seven more Phase 3 readouts expected in 2026. NDA submission expected late 2025/early 2026.
Dosing for Obesity Treatment

Other Peptides for Obesity Treatment
These peptides are also researched for obesity treatment.
Semaglutide
FDAA GLP-1 receptor agonist with multiple FDA approvals including weight loss, T2D, CV risk reduction, and kidney protection. Wegovy pill approved Dec 2025 as first oral GLP-1 for weight loss.
Tirzepatide
FDAA dual GIP/GLP-1 receptor agonist representing the next generation of incretin-based therapies. Shows superior weight loss compared to semaglutide in head-to-head trials. First medication approved for obstructive sleep apnea.
Survodutide
Clinical TrialsA dual GLP-1/glucagon receptor agonist in development for obesity and MASH. Has FDA Breakthrough Therapy Designation for MASH with fibrosis.
Cagrilintide
Clinical TrialsA long-acting amylin analog developed by Novo Nordisk for obesity treatment. Works through a different mechanism than GLP-1 agonists, targeting amylin receptors in the brain to reduce appetite and slow gastric emptying. Shows enhanced weight loss when combined with semaglutide (CagriSema).
