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

    1. Mean % change in BMI [From Baseline to Week 60]

    Secondary Outcome Measures

    1. 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]

    2. Mean change in the weekly average of the daily most hunger score in patients ≥12 years old [From Baseline to Week 60]

    3. Proportion of patients with a ≥2 point reduction in the weekly average of the daily most hunger score [From Baseline to Week 60]

    4. Mean change in Symptoms of Hyperphagia total score [From Baseline to Week 60]

    5. Proportion of patients with a ≥10% reduction in BMI [From Baseline to Week 60]

    6. Mean percent change in weight in patients ≥18 years [From Baseline to Week 60]

    7. 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]

    8. Proportion of patients aged ≥4 to <18 years with ≥0.2-point reduction of BMI Z-score [From Baseline to Week 60]

    9. Proportion of patients with BMI <30 kg/m2 (patients aged ≥18 years) or <95th percentile (patients aged <18 years) [From Baseline to Week 60]

    10. 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]

    11. 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]
