Carbetocin for the Treatment of PWS

Study Purpose

Carbetocin (LV-101) is an investigational drug that was created to have effects in the body like oxytocin.  Carbetocin is not approved in the United States, but is approved in some other countries for treatment of women with excessive bleeding after giving birth via caesarean section. This Phase 3 study of intranasal carbetocin (LV-101) is a randomized, double-blind study with an 8-week, placebo controlled period, followed by 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.
