A Single Arm, Open Label, Clinical Study of Cryopreserved Autologous CD34+ Cells Transduced With Lentiviral Vector Containing Human ARSA cDNA (OTL-200), for the Treatment of Early Onset Metachromatic Leukodystrophy (MLD)

In Brief

A Phase 2 clinical trial evaluating OTL-200 for Lysosomal Storage Disease and Metachromatic Leukodystrophy. Completed, enrolled 10 participants across 1 site.

Detailed Summary

OTL-200 is autologous CD34+ cells transduced with lentiviral vector containing human arylsulfatase A (ARSA) complementary deoxyribonucleic acid (cDNA) used for the treatment of MLD. MLD is an autosomal recessive lysosomal storage disorder (LSD) characterized by severe and progressive demyelination affecting the central and peripheral nervous system. This study will assess safety and efficacy of treatment using cryopreserved formulation of OTL-200 in pediatric subjects with pre-symptomatic Early Onset MLD (Late Infantile (LI) to Early Juvenile (EJ) MLD) and early symptomatic EJ MLD.
