Summary
This research study is being conducted to find out whether Trappsol® Cyclo™, an experimental
treatment for people with Niemann-Pick disease Type C1 (NPC-1) is safe at 3 different dose
levels and what effects it has on people who have this condition. NPC-1 is caused by a defect
in a 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 56 weeks in total. recruitment is expected to take 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. Samples of Cerebrospinal fluid (CSF) are also taken by
lumbar puncture during and following the first treatment dose. 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. Optional assessments patients can
choose to take part in include liver biopsies, additional lumbar punctures for
CSF.examinations to see if the drug is affecting these. This study is being sponsored and
funded by CTD holdings INC. It is planned to be run in the UK, Italy, and Sweden.
