Arm description |
Adult and pediatric subjects aged 4 years and older, with established diagnosis of niemann-pick disease type C (NPC) were enrolled and recieved miglustat 200 miligrams (mg) from Day 1 through Week 52. Adult subjects received miglustat 200 mg thrice daily (t.i.d), while for subjects with mild renal impairment, the starting dose was 200 mg twice daily (b.i.d) and for moderate renal impairment, the starting dose was 200 mg once daily. For subjects with NPC less than 12 years of age, dosage regimen (0.2 grams [g] t.i.d, 0.2 g b.i.d, 0.1 g t.i.d, 0.1 g b.i.d, and 0.1 g once daily) was adjusted based on body surface area (BSA). | ||||||||||||

Change From Baseline to Week 52 in Horizontal Saccadic Eye Movement (HSEM) as Measured by Saccadic Peak Acceleration [1] | ||||||||
End point description |
Change from baseline to Week 52 in HSEM as measured by saccadic peak acceleration was reported. Saccadic eye movements (SEM) were rapid eye movements under voluntary control (including saccade initiation, speed and extent) that were essential for the normal shifting of focus from one object to another within the visual field. Full analysis set included all enrolled subjects who completed the screening period. Here, 'N' (number of subjects analysed) signifies number of subjects who were evaluable for this endpoint.

Number of Subjects with Treatment-emergent Serious Adverse Events (TESAEs) | ||||||
End point description |
A SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. An AE is any untoward medical occurrence, i.e., any unfavorable and unintended sign, including an abnormal laboratory finding, symptom, or disease that occurs in a subject during the course of the study, whether or not considered by the investigator as related to study treatment. Treatment-emergent SAEs are defined as serious events between administration of study drug and after the last dose that were absent before treatment or that worsen relative to pretreatment state. The safety set (SS) included all subjects who received at least one dose of miglustat.
