Study of the Pharmacokinetics of Trappsol and Effects on Potential Biomarkers of Niemann-Pick C1 (NPC1)

Completed · Phase 1

Conditions studied: Niemann-Pick Disease, Type C1

In brief

This research study is being conducted to find out whether Trappsol® Cyclo™, an experimental treatment for people with Niemann Pick disease Type C (NPC-1) is safe at 2 different dose levels and what effects it has on people who have this condition. NPC-1 is caused by a defect in the protein which is important for the transport of fatty substances like cholesterol out of cells. Without this protein, fats build up in the cells ultimately leading to organ damage. The way in which this experimental treatment works is not fully understood but laboratory experiments have shown that it can potentially remove cholesterol build up from the cells in people who have NPC-1. Approximately 12 patients will be asked to take part in this research study for up to 20 weeks (w) in total (including screening. treatment and follow-up). Recruitment is expected to take 6- 9 months.Patients who take part will receive treatment by an intravenous infusion every two weeks. The study will look at what the body does to the drug as well as what the drug does to the body by taking and examining blood and urine samples. A sample(s) of cerebrospinal fluid (CSF) will be taken by lumbar puncture during the first treatment dose and may be collected during subsequent doses. Liver and skin biopsy specimens will be taken to assess filipin staining. Cholesterol metabolism will be investigated in liver samples and splenic and hepatic elasticity will be assessed by ultrasound. Patients will also have their hearing tested, be asked questions by their doctor as well completing questionnaires to help assess any changes in their condition during treatment.This study is being sponsored and funded by CTD holdings Inc. It is planned to be run in the USA,.
