A Trial of Setmelanotide in Patients With Congenital Hypothalamic Obesity (Sub-study of NCT05774756)

Официальное название

A Phase 3, Double Blind, Randomized, Placebo-Controlled Trial to Evaluate the Efficacy and Safety of Setmelanotide in Patients With Acquired Hypothalamic Obesity

Обзор

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.

Вмешательства

• Препарат Setmelanotide
  Solution for daily subcutaneous injection
• Препарат Placebo
  Placebo matched to setmelanotide for daily subcutaneous injection
