Gene Transfer Clinical Trial for Infantile and Late Infantile Krabbe Disease Treated Previously With HSCT

Summary

This is a non-blinded, non-randomized dose escalation study of intravenous FBX-101 in which subjects will receive a single infusion of an adeno-associated virus gene therapy product, after more than 21 days of the HSCT (UCBT preferred HSCT source). Data from previously transplanted patients with infantile and late infantile Krabbe disease will be used as a comparator group.
