Brief summary (registry, in English)

This is a sub-study of Study RM-493-040 (NCT05774756). The goal of this sub-study is to learn how well Setmelanotide works to improve weight reduction, hunger, and quality of life in patients 4 years of age and older with congenital Hypothalamic Obesity (cHO). To determine how well setmelanotide works and how safe it is, patients with cHO will take a daily injection of either setmelanotide or placebo and complete trial assessments for up to 26 weeks on a therapeutic regimen.
