Interventions

Onasemnogene Abeparvovec-xioibiological

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).
