About Trappsol® Cyclo™ (hydroxypropyl-beta-cyclodextrin) Trappsol® Cyclo™ (hydroxypropyl-beta-cyclodextrin) is a first-in-class propriety cyclodextrin formulation administered intravenously (IV) that mobilizes lysosomal cholesterol. Trappsol® Cyclo™ is designed to directly impact the root cause of Niemann-Pick Disease Type C1 (NPC1) by mobilizing cholesterol from late-stage endosomes and lysosomes. Trappsol® Cyclo™ has also been shown to cross the blood-brain barrier after IV administration, suggesting that therapeutic concentrations are reached in the central nervous system over the infusion time window. The potential clinical significance of those concentrations will be evaluated based upon the results of the Phase 3 TransportNPC study.About the Trappsol® Cyclo™ Study Program The Phase 3 TransportNPC study is a prospective, randomized, double-blind, placebo-controlled study evaluating the safety and efficacy of Trappsol® Cyclo™ (hydroxypropyl-beta-cyclodextrin) administered intravenously (2000 mg/kg dose every 2 weeks) in patients aged 3 years and older with confirmed diagnosis of Niemann-Pick Disease Type C1 (NPC1) (CTD-TCNPC-301; NCT04860960). The TransportNPC study enrolled 94 patients in over 25 sites across 13 countries. The study duration is 96 weeks, an unblinded interim analysis was reviewed by an independent DMC when all patients reached 48 weeks and recommended to continue the study for the full 96 weeks. A Phase 3 open-label extension study of up to 96 weeks follows the interventional study.The primary endpoints of the Phase 3 TransportNPC study are the mean change in the 4-domain NPC Clinical Severity Scale (4D-NPC-CSS) score in the United States and the 5-domain NPC Clinical Severity Scale (5D-NPC-CSS) score in Europe. The 4D-NPC-CSS score (inclusive of ambulation, fine motor, speech, and swallow) and 5D-NPC-CSS score (inclusive of ambulation, fine motor, speech, swallow, and cognition) are measures of NPC disease progression that look at items that patients with NPC and their caregivers and physicians have identified as most relevant. Important secondary and exploratory endpoints will also be assessed across measures of disease activity.As part of the Phase 3 study, a Phase 3 open-label sub-study is being conducted in NPC1 patients from birth to 3 years of age outside of the United States. Ten patients have been recruited and are continuing in the study. Outcomes for the sub-study include safety, clinical, and caregiver impression of the disease.Cyclo Therapeutics has completed 2 studies, including a Phase 1 study (CTD-TCNPC-101; NCT02912793) and a Phase 2 study (CTD-TCNPC-201; NCT02912793). Patients who completed the Phase 1 study continue to receive Trappsol® Cyclo™ treatment in the ongoing Phase 1 open-label extension study (CTD-TCNPC-102; NCT03893071).About Niemann-Pick Disease Type C1 (NPC1) Niemann-Pick Disease Type C1 (NPC1) is a rare genetic disease that affects approximately 1 in 100,000 live births globally and often leads to premature death. NPC1 is characterized by an inability for cells to transport and process cholesterol, resulting in excessive amounts of cholesterol accumulating and damaging affected organs, including the liver, spleen, and brain. The disease can be life-limiting, with symptoms including progressive intellectual decline, loss of motor skills, seizures, and dementia. Approximately 95% of individuals with NPC have mutations in the NPC1 gene, and 5% have mutations in the NPC2 gene. About Rafael Holdings, Inc.
