A Trial of Setmelanotide in Acquired Hypothalamic Obesity
Study Details
Study Description
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 up to 60 weeks.

Outcome Measures
Primary Outcome Measures
- Mean % change in BMI [From Baseline to Week 60]
Secondary Outcome Measures
- Proportion of patients with ≥5% reduction in BMI in adult patients (≥18 years of age) or a BMI Z-score reduction of ≥0.2 points in pediatric patients (<18 years of age) [From Baseline to Week 60]
- Mean change in the weekly average of the daily most hunger score in patients ≥12 years old [From Baseline to Week 60]
- Proportion of patients with a ≥2 point reduction in the weekly average of the daily most hunger score [From Baseline to Week 60]
- Mean change in Symptoms of Hyperphagia total score [From Baseline to Week 60]
- Proportion of patients with a ≥10% reduction in BMI [From Baseline to Week 60]
- Mean percent change in weight in patients ≥18 years [From Baseline to Week 60]
- Mean BMI-z score and BMI percentile reduction in patients <18 (using combined height and weight to report BMI in kg/m2) [From Baseline to Week 60]
- Proportion of patients aged ≥4 to <18 years with ≥0.2-point reduction of BMI Z-score [From Baseline to Week 60]
- Proportion of patients with BMI <30 kg/m2 (patients aged ≥18 years) or <95th percentile (patients aged <18 years) [From Baseline to Week 60]
- Mean change in physical functioning score and total score for the Impact of Weight on Quality of Life-Lite (IWQOL) [From Baseline to Week 60]
- Safety and tolerability of setmelanotide compared to placebo assessed by frequency and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs) [From Baseline to Week 60]
