Conclusion: This systematic review identifies the state and mechanism of action of emerging pharmacotherapies undergoing or having completed phase 2 and phase 3 clinical trials. The information provided herein furthers the understanding of obesity management, implying direct clinical implications and stimulating research initiatives.
PubMed 39952695 ↗Conclusion: GLP-1 RAs and co-agonists are efficacious for weight loss, with reported safety concerns predominantly gastrointestinal in nature, when used among adults with overweight or obesity and without diabetes.
PubMed 39761578 ↗Conclusion: GLP-1 RAs carry a slightly increased risk of pancreatitis, which is not significant when stratified by background medication use. Overall risk for pancreatic cancer was not observed, but a slight association was found when stratified with background medications. However, this difference is likely minimal, given the numerous studies excluded from the meta-analysis where both treatment arms had zero events.
PubMed 40988099 ↗Conclusion: Retatrutide (both doses) and tirzepatide exhibited superior efficacy compared to other GLP-1 receptor agonists and polyagonists in reducing body weight and waist circumference. Patients without T2DM, those with a high BMI, and individuals undergoing longer treatment cycles demonstrated significantly greater weight loss and reductions in waist circumference. Dual or triple receptor agonists (GLP-1 plus glucose-dependent insulinotropic polypeptide and/or Glucagon receptor) are more effective for weight loss than GLP-1 receptor agonists.
