Primary |
Part A: Change from baseline in the 9-item Hyperphagia Questionnaire for Clinical Trials (HQ-CT) |
The HQ-CT is a questionnaire designed to measure symptoms of food-related preoccupations, problems, and behaviors completed by the caregiver. The scale provides a composite value from 9 questions, each rated on a scale of 0 to 4 units (possible total score range: 0 to 36). Higher scores represent increased hyperphagia. |
Part A: Baseline to Day 42 |

Part B: Change from baseline in the 9-item Hyperphagia Questionnaire for Clinical Trials (HQ-CT) |
The HQ-CT is a questionnaire designed to measure symptoms of food-related preoccupations, problems, and behaviors completed by the caregiver. The scale provides a composite value from 9 questions, each rated on a scale of 0 to 4 units (possible total score range: 0 to 36). Higher scores represent increased hyperphagia. |

Part A and Part B: Change from baseline in the 9-item Hyperphagia Questionnaire for Clinical Trials (HQ-CT) |
The HQ-CT is a questionnaire designed to measure symptoms of food-related preoccupations, problems, and behaviors completed by the caregiver. It consists of 9 items, with a 2-week recall period. The scale provides a composite value from 9 questions, each rated on a scale of 0 to 4 units (possible total score range: 0 to 36). Higher scores represent increased hyperphagia. |

Part A and Part B: Change from baseline in Hyperphagia Questionnaire for Clinical Trials (HQ-CT) domain scores (drive and severity, self-directed behavior) |
The HQ-CT is a questionnaire designed to measure symptoms of food-related preoccupations, problems, and behaviors completed by the caregiver. The scale provides a composite value from 9 questions, each rated on a scale of 0 to 4 units (possible total score range: 0 to 36). Higher scores represent increased hyperphagia. |

Secondary |
Part A and Part B: Caregiver Global Impression-Change (CaGI-C) |
