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.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing VTS-270 in people with Niemann-Pick Disease, Type C1, run by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 0 inclusion and 32 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 30 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 30 Aug 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Participants With Adverse Events by Grade (time frame: 18 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03887533, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Aug 2022.
