SPINRAZA® contains the active substance nusinersen, which belongs to a group of medicines known as antisense oligonucleotides (ASOs).1
SPINRAZA® increases the proportion of SMN2 mRNA transcripts that include exon 7 by targeting SMN2 pre-messenger ribonucleic acid (pre-mRNA).1
Once SMN2 mRNA with exon 7 is produced, it can be translated into functional, full-length SMN protein.1
