Study Overview
=================
Brief Summary
-----------------
This is a phase II randomized controlled study of miglustat in adult and juvenile patients with Niemann-Pick Type C disease. Up to 42 patients will be randomised in a 2:1 ratio to either treatment with miglustat or to a non-treatment group. Both groups will follow an identical visit schedule.

Inclusion Criteria: Patients with Niemann-Pick Type C disease confirmed by abnormal cholesterol esterification and abnormal filipin staining. Patients who can ingest a capsule. Patients who are above the age of four (4) years of age. Exclusion Criteria: Patients younger than 18 years who are unable to give informed assent and/or whose legal guardian is unable to provide informed consent. Patients aged 18 and over who cannot provide informed consent and/or whose legal guardian is unable to provide witnessed informed consent.

Patients who cannot tolerate the study procedures or who are unable to travel to the study center as required by this protocol. Patients currently undergoing therapy with other investigational agents or patients taking drugs or food supplements which may interfere with gastrointestinal absorption or motility. Patients suffering from clinically significant diarrhea (>3 liquid stools per day for >7 days) without definable cause within 3 months of Screening Visit, or who have a history of significant gastrointestinal disorders. Patients with an intercurrent medical condition that would render them unsuitable for the study e.g. HIV, hepatitis infection. Patients who in the opinion of the Investigator (for whatever reason) are thought to be unsuitable for the study. Patients with an adjusted Creatinine Clearance of less than 70 ml/min/1.73m2 (CrCl <70). Patients younger than four (4) years of age.
