Regulatory Update on Nusinersen by Biogen
CAMBRIDGE, Mass. -- Biogen Inc. (Nasdaq: BIIB) has recently shared an important update regarding the high dose regimen of nusinersen, a treatment aimed at spinal muscular atrophy (SMA). This follows a Complete Response Letter (CRL) issued by the U.S. Food and Drug Administration (FDA) concerning Biogen's supplemental New Drug Application (sNDA).
Understanding the FDA's Response
The FDA's letter highlights a request for additional technical information to be included in the Chemistry Manufacturing and Controls (CMC) section of the sNDA. Importantly, no deficiencies were noted in the clinical data for the high dose regimen, signaling that the core efficacy findings remain intact and the path forward is still viable.
In response, Biogen has expressed its commitment to re-engaging with the FDA quickly, ensuring that the necessary information is submitted without unnecessary delays. According to Priya Singhal, M.D., M.P.H., the Head of Development at Biogen, the company is determined to make this treatment available to those living with SMA, underlining the urgency and importance of the situation.

Efforts are not limited to the United States.
