Brief Summary:
This Phase 3 study is designed to test the effectiveness of intranasal carbetocin (LV-101) in participants with Prader-Willi syndrome (PWS). Carbetocin is an oxytocin analog (a man-made chemical that is like oxytocin). This study will also evaluate the safety and tolerability of LV-101.

Condition or disease Intervention/treatment Phase
Prader-Willi Syndrome Drug: intranasal carbetocin Dose 1 Drug: intranasal carbetocin Dose 2 Drug: placebo Phase 3

Detailed Description:

This is a Phase 3 randomized, double-blind study with an 8-week, placebo-controlled period designed to test the effectiveness, safety, and tolerability of LV-101 in participants with PWS.

Effectiveness will be measured using both caregiver-reported and clinician-reported measures of hyperphagia (extreme hunger), obsessive and compulsive behaviors, and anxiety. Safety and tolerability will be measured by adverse events, laboratory tests, and physical exams.

After the 8-week placebo-controlled period, there will be a long-term follow-up period of 56 weeks during which all participants will receive active treatment with LV-101. At Week 8, participants who were randomized to placebo in the placebo-controlled period will be randomized to one of the two LV-101 doses, administered three times per day before meals.

    Change in obsessive and compulsive behaviors as measured by the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) Total Score versus placebo

Secondary Outcome Measures :
  1. Anxiety [ Time Frame: baseline to Week 8 ]
    Change in participant anxiety as measured by the PWS Anxiety and Distress Questionnaire (PADQ) Total Score versus placebo

  2. Global impression [ Time Frame: baseline to Week 8 ]
    Change in Clinical Global Impression of Change (CGI-C) score versus placebo

  3. Hyperphagia behavior [ Time Frame: baseline to Week 8 ]
    Change in hyperphagia as measured by the change in specified subsets of HQ-CT questions versus placebo
