Obesity

Impact of Setmelanotide on Metabolic Syndrome Risk in Patients With Bardet-Biedl Syndrome

J Clin Endocrinol MetabPublished Secondary analysis of a phase 3 trial

Authors' conclusion

MetS-Z-BMI score reductions were observed after 52 weeks of treatment, suggesting that setmelanotide may decrease metabolic syndrome severity and risk of future obesity-related comorbidities in those with BBS.
