Biogen today announced that it has received approval from the U.S. Food and Drug Administration (FDA) for the High Dose regimen of SPINRAZA (nusinersen) to treat people living with spinal muscular atrophy (SMA). With broad label approval for all those living with SMA, this is an excellent result for the SMA community.
SPINRAZA (nusinersen) is an antisense oligonucleotide therapy that works by increasing production of survival motor neuron (SMN) protein, which is critical for motor neuron function. The High Dose regimen is designed to further enhance SMN protein levels.
This FDA approval marks another important step forward in the ongoing effort to treat and manage SMA. The High Dose regimen of SPINRAZA has the potential to provide additional benefit, offering new possibilities for improved outcomes and quality of life. Cure SMA is committed to working closely with Biogen, healthcare providers, and the SMA community to support timely education and access to this new dosing option, in alignment with its approved use.
