Study Summary

This is a multinational, multicenter, open-label, rater-blinded prospective Phase II study which will assess the safety and efficacy of N-Acetyl-L-Leucine (IB1001) for the treatment of Niemann-Pick type C disease (NPC). There are two phases to this study: the Parent Study, and the Extension Phase. The Parent Study evaluates the safety and efficacy of N-Acetyl-L-Leucine (IB1001) for the symptomatic treatment of NPC. The Extension Phase evaluates the long-term safety and efficacy of IB1001 for the neuroprotective, disease-modifying treatment of NPC.

Primary Outcome

The Clinical Impression of Change in Severity assessment will instruct the blinded rater to consider: 'compared to the first video, how has the severity of their performance on the 9 Hole Peg Test of the Dominant Hand (9HPT-D) or 8 Meter Walk Test (8MWT) changed (improved or worsened) in 6-weeks as observed in the second video?' The Clinical Impression of Change in Severity is evaluated on a 7 point Likert scale (+3=significantly improved to -3= significantly worse).
