Study of IV VTS-270 for Infantile Liver Disease Associated With Niemann-Pick Disease, Type C

United States4 participantsStarted 2019-02-22

Plain-language summary

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 Niemann-Pick C1 disease (NPC1) (\~95% of cases) or NPC2 genes. 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 central nervous system decline including inability to coordinate balance, gait, extremity and eye movements. Acute liver disease in the newborn/infant period is frequently observed, but subsequently resolves. However, chronic, sub-clinical liver disease persists. Intrathecal 2-Hydroxypropyl-β-Cyclodextrin (HP-β-CD, VTS-270), also known as adrabetadex, has proven effective in reducing the signs and prolonging life in animal models and Phase 1/2a data support efficacy in NPC1 patients. Adrabetadex (VTS-270) also has been shown to be effective in treating liver disease in the NPC1 cat. This Phase 1/2a, open-label, multiple ascending dose trial will evaluate whether adrabetadex (VTS-270) administered intravenously is effective in treating acute liver disease in NPC1 infants.

. Diagnosis of NPC (either NPC1 or NPC2) based upon meeting any of the two following conditions:
. Subjects with evidence of NPC-related liver disease as defined by direct bilirubin (DB) \>2mg/dL or DB/total bilirubin ratio \>0.2.
. Ability to travel to a research site.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
