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.

Conditions

  • Niemann-Pick Disease, Type C

Interventions

DRUG

VTS-270

VTS-270 (2-Hydroxypropyl-Beta-Cyclodextrin) will be administered intravenously to specifically target liver disease. In the first phase of the study, dosing frequency will be twice a week with IV adrabetadex (VTS-270) for six weeks for a total of 12 administrations. Subjects will be evaluated at each study visit for evidence of adverse effects. Doses to be studied are 500, and 1000 mg/kg. Six subjects will be studied at each dose level. Cohort 1: Subjects 1-6, 500 mg/kg Cohort 2: Subjects 7-12, 1000 mg/kg
