Phase 3 Study to Evaluate Intravenous Trappsol(R) Cyclo(TM) in Pediatric and Adult Patients With Niemann-Pick Disease Type C1

Summary

A prospective, randomized, double-blind, placebo controlled, multi-center therapeutic study for patients age 3 and older with confirmed diagnosis of Niemann Pick disease type C1 (NPC1). The objective of this study is to evaluate the safety, tolerability and efficacy of 2000 mg/kg dose of Trappsol Cyclo (hydroxypropyl betacyclodextrin) administered intravenously compared to standard of care. An open-label sub-study in countries following European Medicines Agency (EMA) guidance will enroll asymptomatic or symptomatic patients from infancy up to age 3 to evaluate safety in that population.
