Phase 3, Open-Label, Single-Arm, Single-Dose Gene Replacement Therapy Clinical Trial for Patients With Spinal Muscular Atrophy Type 1 With One or Two SMN2 Copies Delivering AVXS-101 by Intravenous Infusion
In Brief
A Phase 3 clinical trial evaluating Onasemnogene Abeparvovec-xioi for SMA. Completed, enrolled 33 participants across 10 sites in 4 countries.
Detailed Summary
Phase 3, open-label, single-arm, single-dose, trial of onasemnogene abeparvovec-xioi (gene replacement therapy) in patients with spinal muscular atrophy (SMA) Type 1 who meet enrollment criteria and are genetically defined by a biallelic pathogenic mutation of the survival motor neuron 1 gene (SMN1) with one or two copies of survival motor neuron 2 gene (SMN2). Up to 30 patients \< 6 months (\< 180 days) of age at the time of gene replacement therapy (Day 1) will be enrolled.

Interventions
Onasemnogene abeparvovec-xioi is a non-replicating recombinant adeno-associated virus serotype 9 (AAV9) containing the human survival motor neuron (SMN) gene under the control of the cytomegalovirus (CMV) enhancer/chicken β-actin-hybrid promoter (CB).
