Registered outcomes7

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryChange From Baseline in Hyperphagia Behavior as Measured by the Hyperphagia Questionnaire for Clinical Trials (HQ-CT)Baseline, Week 13
The HQ-CT measures hyperphagia by Prader-Willi syndrome (PWS)-specialized clinicians. The HQ-CT generates a score ranging from 0 to 36, where a higher score represents more severe abnormal food related behaviors. The change from baseline was calculated from two time points as the value at the later time point minus the value at the earlier time point: value at Week 13 minus value at Baseline.
SecondaryChange From Baseline In Total Body WeightBaseline, Week 13
Total body weight refers to participants' weight throughout the study. The change from baseline was calculated from two time points as the value at the later time point minus the value at the earlier time point: value at Week 13 minus value at Baseline.
SecondaryResponder Rate From Baseline Through Study CompletionBaseline up to Week 13A responder was defined as having a 6 or more points decrease in HQ-CT score.
SecondaryChange In Patient Global Impression Of Change (PGI-C) QuestionnaireWeek 3, Week 13The change in PGI-C scores at Week 3, Week 9, and Week 13 of the participant are evaluated.
SecondaryChange From Baseline In The Three Factor Eating Questionnaire - 18-item Version (TFEQ-R18)Baseline, Week 13The change from baseline to Week 13 of the participant's TFEQ-R18 score is evaluated.
SecondaryChange From Baseline In Quality Of Life [Patient-Reported Outcomes Measurement Information System (PROMIS) Life Satisfaction And Positive Affect Questionnaires]Baseline, Week 13The change from baseline to Week 13 of the participant's quality of life (PROMIS life satisfaction and positive affect questionnaire) score is evaluated.
SecondaryChange From Baseline In Physical Activity (PROMIS Physical Activity And Fatigue Questionnaires)Baseline, Week 13The change from baseline to Week 13 of the participant's physical activity (PROMIS physical activity and fatigue questionnaires) score is evaluated.
