ZOLGENSMA (onasemnogene abeparvovec-xioi)

How It Works

Zolgensma works by delivering a functional copy of the SMN gene into the patient’s cells using a viral vector called adeno-associated virus 9 (AAV9). This vector targets motor neuron cells and introduces the healthy SMN gene, which then produces the survival motor neuron (SMN) protein. This protein is essential for the maintenance and function of motor neurons, and its presence helps to improve muscle function and slow the progression of SMA.
