Outcomes

Primary Outcome Measures

Number of Participants With ≥ 5% Reduction in Body Weight From Baseline After 3 Months of Setmelanotide Treatment

Secondary Outcome Measures

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
An adverse event (AE) was any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug-related. An AE (also referred to as an adverse experience) could be any unfavorable and unintended sign (e.g., an abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, without any judgment about causality. TEAEs were defined as AEs reported after dosing on Day 1.
Change From Baseline in Body Weight After 3 Months of Setmelanotide Treatment
Percent Change From Baseline in Body Weight After 3 Months of Setmelanotide Treatment
Change From Baseline in Daily Hunger Questionnaire Scores After 3 Months of Setmelanotide Treatment in Participants Aged ≥ 12 Years
The mean change in daily hunger questionnaire scores for participants ≥ 12 years of age with obesity in treatment with setmelanotide was evaluated. On the Daily Hunger Questionnaire, each of the 3 items (average hunger in the last 24 hours, most/worst hunger in the last 24 hours, and morning hunger) was assessed daily and scored separately using a numeric rating score for each from 0 to 10, with 0 = not hungry at all and 10 = hungriest possible.
Change From Baseline in Daily Hunger Questionnaire Scores After 3 Months of Setmelanotide Treatment in Participants Aged < 12 Years
The mean change in daily hunger questionnaire scores for participants < 12 years of age with obesity in treatment with setmelanotide was evaluated. Hunger was assessed daily using a Daily Hunger Questionnaire with a pictorial (smiley face) version of the Likert rating scale with scores ranged from 0 to 4, with 0 = not hungry at all and 4 = hungriest possible.
Number of Participants With Shifts From Baseline in Global Hunger Questionnaire Scores After 3 Months of Setmelanotide Treatment in Participants Aged ≥ 12 Years
For participants ≥ 12 years of age, the following question was asked using the Global Hunger Questionnaire: Overall, how would you rate the hunger you experience now? Possible responses were: No hunger; Mild hunger; Moderate hunger; Severe hunger; and Not answered.
Number of Participants With Shifts From Baseline in Global Hunger Questionnaire Scores After 3 Months of Setmelanotide Treatment in Participants Aged < 12 Years
For participants < 12 years of age, the following question was asked to parents or caregivers of participants using the Global Hunger Questionnaire: How hungry is your child acting now? Possible responses were: Not hungry at all; A little hungry; Moderately hungry; Extremely hungry; and Not answered.
Percent Change From Baseline in Waist Circumference After 3 Months of Setmelanotide Treatment
Waist circumference (cm) was measured according to the National Heart, Lung, and Blood Institute (NHLBI) criteria. All measurements were single measures. Waist circumference was measured when participants were in fasting condition and at approximately the same time at each visit.
