Abstract
Background: A malfunction in the melanocortin-4 receptor (MC4R) is associated with obesity in rare genetic syndromes; setmelanotide is a new drug that activates this receptor and is being used to treat severe obesity. This meta-analysis evaluated the efficacy and safety of setmelanotide for weight loss in severe obesity linked to human MC4R deficiency. Methods: We searched PubMed, Embase, and Cochrane for randomized and nonrandomized clinical trials using setmelanotide. We considered a p-value ≤ 0.05 statistically significant. Results: We included 376 patients, of whom 328 (87.2%) received setmelanotide for a mean follow-up of 52 weeks. The mean age was 32.8 (14.67) years. Weight loss was significant (MD −3.52; 95% CI −3.98, −3.05; p = 0.01; I2 = 92%), with an average proportion of −6.91% weight loss during treatment. Changes in BMI showed an MD of −10.55 kg/m2 in patients > 18 years and −0.61 kg/m2 in patients < 18 years (BMI score). However, the drug was associated with a higher risk of skin hyperpigmentation (OR 0.69; 95% CI 0.55, 0.80; p = 0.08). Conclusions: Our results support the use of setmelanotide in treating severe obesity. [ABSTRACT FROM AUTHOR]
