Brief Summary:
Background:
For people who have Niemann-Pick disease, type C1 (NPC1), cholesterol and other fats have trouble moving out of liver and other tissue cells. This makes the cells sick. Researchers want to find out if a drug called VTS-270 can help.
Objective:
To test if VTS-270 is safe and effective in treating chronic liver disease associated with NPC1.
Eligibility:
People ages 3-60 with NPC1
Design:
Participants may be screened by phone or under another protocol.
Participants will have visits once a month for 12 months. If they have intrathecal injections, the study may last 15 months or more. The first visit will last about 5 days. Others will last 2-3 days.
Participants will get VTS-270 injected into a vein at each visit. They can also choose to have intrathecal injections. These are like spinal taps.
Some visits will also include:
Physical exam
Urine tests
Blood tests. A small tube or needle will be inserted into the participants vein to collect blood. The small tube will also be used to give the VTS-270.
Hearing tests: For one test, participants will have electrodes taped to their head. These will record brain waves.
Breathing tests
Ultrasound of abdomen: Sounds waves will take pictures of the participant s body.
Chest x-ray: This is a picture of the lungs.

Detailed Description:
Niemann-Pick disease type C (NPC) is a lethal, autosomal recessive, lysosomal storage disorder characterized by neurodegeneration in early childhood and death in adolescence. NPC results from mutation of either the NPC1 (approximately 95% of cases) or NPC2 genes. Biochemically, NPC is characterized by the endolysosomal storage of unesterified cholesterol and lipids in both the central nervous system and peripheral tissues such as the liver. Individuals with NPC demonstrate progressive cerebellar ataxia and dementia. Acute cholestatic liver disease is frequently observed in the neonatal/infantile period but subsequently resolves. However, chronic, sub-clinical liver disease persists. Intrathecal 2-hydroxypropyl-beta-cyclodextrin (HPbetaCD, VTS-270) has proven effective in reducing signs and prolonging life in NPC1 animal models, and Phase 1/2a data support efficacy in NPC1 patients. Parenteral administration of VTS-270 has also been shown to be effective in treating liver disease in the NPC1 cat.
In this Phase 1/2a, open-label, randomized, parallel dose, single-center study, we will examine whether VTS-270 can be used to treat chronic subacute liver disease in NPC1 patients. Our primary objective is to determine the safety and tolerability of intravenous VTS-270 in NPC1 disease. Secondary objectives will be to evaluate the efficacy of VTS-270 to reduce plasma cholestane-3beta,5alpha,6beta-triol, an NPC1-specific pharmacodynamic biomarker, and to normalize the degree of liver injury. Exploratory testing will include lipid and protein biomarkers. This study will evaluate three dose levels (500, 1000 and 1500 mg/kg) administered monthly for twelve months. Safety will be assessed by adverse event recording, clinical laboratory testing and physical examination. Clinical efficacy will be evaluated by assessment of liver chemistries, determination of liver size; and liver STIFFNESS. Biochemical efficacy will be assessed by measurement of plasma cholestane-3beta,5alpha,6beta-triol and other biomarkers.
