Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an observational study that will enroll any patients with Krabbe disease that have participated in prior interventional clinical trials involving the administration of FBX-101.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

FBX-101-LTFU is a multicenter, non-interventional, Long-Term Follow-Up (LTFU) study of participants from prior interventional trials involving the administration of FBX-101. Eligible participants will undergo clinical evaluations at prespecified intervals for at least 3 years from the last visit in the prior clinical trial (up to 5 years post-FBX-101 treatment). Overall safety and additional signs of efficacy will be collected with a series of laboratory tests, diagnostic tests, and performance surveys. Additionally, children participating in interventional trials that are terminated early will be transferred to this LTFU study and will complete any pending visits from the interventional trial before starting the clinical evaluations included in this protocol.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients enrolled in the FBX-101-LTFU study

The participants will be followed for 36 months after they have concluded their participation in the interventional trial. They will complete 5 scheduled visits with assessments as specified in the schedule of assessments, to collect data for safety and additional signs of efficacy for FBX-101. Those patients enrolled from any other early terminated trial, will first complete pending evaluations from that trial.

Intervention Type BIOLOGICAL

A replication-deficient adeno-associated virus gene transfer vector expressing the human galactocerebrosidase (hGALC) cDNA will be delivered one-time through a venous catheter inserted into a peripheral limb vein.
