Nusinersen,[7] marketed as Spinraza,[4] is a medication used in treating spinal muscular atrophy (SMA), a rare neuromuscular disorder.[8][4] In December 2016, it became the first approved drug used in treating this disorder.

Since the condition it treats is so rare, Nusinersen has so-called "orphan drug" designation in the United States and the European Union.[9]
