Primary Outcome Measures
NameTimeMethod
Change from Baseline at Week 12 in caregiver-rated Hyperphagia Questionnaire for Clinical Trials (HQ-CT) scoreBaseline to Week 12

The HQ-CT is a nine-item questionnaire designed to be completed by caregivers of subjects with PWS. It is a revision of the 11-item HPWSQ-R and has been further validated. The Foundation for Prader-Willi Research has made the HQ-CT available for clinical studies in PWS, and it is the consensus instrument within the PWS research community for measuring observable behaviors that stem from subjects' excessive drive to eat.

The HQ-CT should be completed by the same caregiver throughout the study. The HQ-CT will be administered to the caregiver by a rater using standardized prompts. The Food Safe Zone should be administered immediately before administration of the HQ-CT.

A higher score on the HQ-CT indicates greater severity of hyperphagia.

Secondary Outcome Measures
NameTimeMethod
Change from Baseline at Week 12 in caregiver-rated Clinical Global Impression-Severity (CGI-S) score for PWSBaseline to Week 12

The CGI-S is a rating scale that records a clinician's global impression of the current severity of illness on a seven-point scale, using a range of responses from 1 (normal) to 7 (among the most severely ill subjects).

Clinical Global Impression-Change (CGI-C) for PWS score at Week 12Score at Week 12

The CGI-C is a rating scale that records a clinician's global impression of change in severity of illness, using a range of responses from 1 (very much improved) to 7 (very much worse).
