Setmelanotide offers significant, long-lasting weight loss


 

Hypothalamic obesity

During the pediatric conference, another speaker presented the results of a phase 2 study that evaluated the efficacy and tolerability of setmelanotide as a new treatment for hypothalamic obesity. Lesions in the hypothalamus can alter melanocortin 4 receptor pathway signaling and thus lead to hypothalamic obesity. Eighteen patients aged 6-40 years with a BMI greater than or equal to the 95th percentile (for patients aged 6-18 years) or greater than or equal to 35 kg/m2 (for adults aged ≥ 18 years) and hypothalamic obesity (craniopharyngioma or other benign brain tumors, surgical removal, and/or chemotherapy) were enrolled. A significant proportion of patients achieved a reduction of greater than or equal to 5% of their BMI (n = 16, 88.9%, CI 90%, 69%-89%, P < .0001), and 72.2% achieved a reduction of greater than or equal to 10% by week 16. The mean change in BMI was −14.9% (9.6%, n = 17). These early results may justify further studies of setmelanotide in treating hypothalamic obesity.

Dr. Dubern has collaborated with Rhythm Pharmaceuticals and Novo Nordisk.
