Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 18 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Single Arm Uncontrolled 12 Months Clinical Study to Evaluate the Safety and Efficacy of Miglustat (Zavesca) for the Treatment of Niemann Pick Type C Disease (NPC) in Chinese Subjects
Estimated Study Start Date : December 20, 2019
Estimated Primary Completion Date : July 1, 2021
Estimated Study Completion Date : February 1, 2022


Arm Intervention/treatment
Experimental: Miglustat
Miglustat is administered three times a day as an oral capsule
Drug: Miglustat
capsule, oral use




Primary Outcome Measures :
  1. Observed change in HSEM (ms/deg) [ Time Frame: baseline to week 52 ]
    Change in HSEM from baseline to week 52


Secondary Outcome Measures :
  1. Change in Pineda disability scale score [ Time Frame: baseline to week 52 ]
    Change in the modified Pineda disability scale score. The scale is assessing 4 key domains (manipulation, ambulation, language and swallowing). Individual scores of the domains are claculated ted into a composite score, 6 being the lowest and best score and 24 being the worst and highest score.

  2. Incidence of treatment-emergent AEs and SAEs [ Time Frame: Baseline to 30 days after End of Treatment (Week 52) ]
    Treatment-emergent adverse events (AEs) up to 30 days after EOT
