Registered outcomes4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change in Hyperphagia and Food-related Behaviors (Hyperphagia Questionnaire for Clinical Trials; HQ-CT) | Baseline to month 3 | Change from baseline to the end of the 3-month Core Period for HQ-CT total score. The HQ-CT score range is 0 to 36 where the higher score represents more severe abnormal food related behaviors. |
| Secondary | Percentage Change From Baseline to Month 3 in Total Body Fat Mass in Patients Eight to 65 Years of Age Defined as Overweight/Obese | Baseline to month 3 | Total body fat mass was assessed using dual energy X-ray absorptiometry (DXA) scan. DXAs were conducted at each local facility using standardized procedures and settings. Overweight/obese patients were defined as follows: * patients ≥18 years of age: BMI ≥27 kg/m2 * patients 4-17 years of age: BMI ≥90th percentile for the same age and sex |
| Secondary | Change From Baseline to Month 3 in Waist Circumference in Patients Eight to 65 Years of Age Defined as Overweight/Obese | Baseline to month 3 | The waist circumference was measured in fasting condition at the superior border of iliac crest, according to recommendations from the Anthropometry Procedures Manual of the National Health and Nutrition Examination Survey, Revised 2007. Overweight/obese patients were defined as follows: * patients ≥18 years of age: BMI ≥27 kg/m2 * patients 4-17 years of age: BMI ≥90th percentile for the same age and sex |
| Secondary | Percentage Change From Baseline to Month 3 in Body Weight in Patients Eight to 65 Years of Age Defined as Overweight/Obese | Baseline to month 3 | Patients were weighed in fasting condition, clothed (underwear, light gown or light clothing), without footwear or heavy jewelry, using a calibrated scale. The same scale should be used throughout the study if possible. The conditions under which patients are weighed should be kept consistent if possible. Overweight/obese patients were defined as follows: * patients ≥18 years of age: BMI ≥27 kg/m2 * patients 4-17 years of age: BMI ≥90th percentile for the same age and sex |
