Evrysdi (risdiplam), marketed by Genentech, a member of the Roche Group, is an FDA-approved therapy to treat SMA. It is an SMN-enhancing therapy that works by targeting the SMN2 gene. It is a small molecule that causes that gene to make more complete SMN protein.

History of Evrysdi

Evrysdi is an oral medicine that is systemically distributed and designed to increase SMN protein levels in the central nervous system (CNS) and throughout the body. It is designed to help the SMN2 gene produce more functional SMN protein, which better supports motor neurons and muscle function. Roche and Genentech led the clinical development of Evrysdi in collaboration with The SMA Foundation and PTC Therapeutics. The approval of Evrysdi was based on four multicenter clinical trials in people with SMA.
