A Trial of Setmelanotide in Acquired Hypothalamic Obesity

Phase 3
Active, not recruiting
Conditions
Hypothalamic Obesity
Interventions
Drug: Placebo
Registration Number
NCT05774756
Lead Sponsor
Rhythm Pharmaceuticals, Inc.
Brief Summary

The goal of this trial 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 acquired Hypothalamic Obesity (HO). To determine how well setmelanotide works and how safe it is, patients with HO will take a daily injection of either setmelanotide or placebo and complete trial assessments for 52 weeks on a therapeutic regimen.

A separate sub-study in patients with congenital HO is detailed under NCT06760546.
