Currently, there are three FDA-approved treatments for SMA:
• Nusinersen (Spinraza) - given by spinal injection, approved for all ages
• Risdiplam (Evrysdi) - oral medication available for all ages
• Onasemnogene abeparvovec-xioi (Zolgensma) - currently only approved for children under age 2

Currently, there are three FDA-approved treatments for SMA:
• Nusinersen (Spinraza) - given by spinal injection, approved for all ages
• Risdiplam (Evrysdi) - oral medication available for all ages
• Onasemnogene abeparvovec-xioi (Zolgensma) - currently only approved for children under age 2
Both Spinraza and Evrysdi work by increasing SMN protein production from the SMN2 gene and are available treatment options for adults. While Zolgensma is currently only approved for young children, researchers are studying its potential use in adults. Early research suggests the viral delivery method used in Zolgensma might be suitable for adult patients regardless of their age, SMA type, walking ability, or ventilatory status. However, this is still being investigated through clinical trials and is not yet an approved treatment option for adults.
