This is an open-label extension study of intravenous HP-β-CD (administered as Trappsol® Cyclo(TM)) in patients with NPC-1 to evaluate long-term safety and efficacy by providing continued access to treatment following completion of study CTD-TCNPC-101. Patients will receive medication at their home or local site under the supervision of a home nurse professional or at the parent site under the supervision of the site principal investigator. Patients will visit the parent site for safety and efficacy evaluations after receiving treatment for 3 months in the extension protocol.
Thereafter, visits to the parent site will be every 6 months until cessation. The study will continue until Trappsol® Cyclo (TM) becomes commercially available or study/site/patient discontinuation. All patients who complete study CTD-TCNCP-101 and pass the screening criteria will be eligible for this study. The study will be directed from parent site in the US. Vital signs, AEs Adverse Events (AEs) and concomitant meds will be recorded by the home nurse professional or deputy at the local site and reported immediately to the parent site for entry into the Electronic Data Capture (EDC) and reporting to the sponsor.
For logistical reasons home infusions will be permitted as long as AEs, infusion details and concomitants medications are reported directly to the parent site by an authorised deputy according to local guidelines. A Safety Review Committee (SRC) consisting of an independent advisor, the medical monitor, and the principal investigator will be established to review AEs and laboratory data throughout the study.
