Key exclusion criteria
1. Has exclusion criteria as assessed by NPC Clinical Severity Scale:

1. Unable to walk, wheelchair dependent (ambulation NPC score=5)
2. Has need for a nasogastric tube to overcome swallowing difficulties (swallowing NPC score=5) unless used for supplemental feeding or administering medication
3. severe dysmetria (fine motor score =5) or
4. minimal cognitive function (cognition NPC score=5)
2. Weighs less than 15 kg
3. Has had prior treatment with intravenous 2-hydroxypropyl-ß-cyclodextrin (HP-ß-CD) for NPC1 disease, unless the subject has undergone a minimum 3-month washout period prior to Study Day 0, or has had any prior intrathecal (IT) administration of HP-ß-CD
4. Is taking antipsychotics for treatment of psychosis; use of antipsychotic medication for treatment of other disorders (e.g., Attention Deficit Hyperactivity Disorder) will not exclude participation in this trial
5. Has a history of hypersensitivity reactions to any product containing HP-ß-CD
6. Has a spinal deformity that could impact the ability to perform a lumbar puncture
7. Has had a skin infection in the lumbar region within 2 months of study entry
