Spinraza is an injection given by a health care provider into the fluid surrounding the spinal cord. This is known as an intrathecal injection. The first 3 doses are given every 14 days, followed by a 4th dose 30 days later. Injections are then given every 120 days.

Spinraza (nusinersen), from Biogen, is the first drug for spinal muscular atrophy (SMA), a rare and often fatal genetic disease affecting muscle strength and movement, primarily in children and young adults.

SMA is caused by low protein levels that are responsible for normal muscle functioning. The lack of protein causes motor neuron loss, worsening muscle weakness and possible death from respiratory failure.
