What is Spinraza™?

Spinraza™ (nusinersen) is the first treatment approved to treat SMA in Europe.

Spinraza™ is intrathecal applied medicine that is designed to increase SMN protein levels in the central nervous system (CNS). This SMN-enhancing therapy is a antisense oligonucleotide that targets the SMN2 gene and helps to increase the amount of stable SMN protein made by this gene.
