Biogen has received a Complete Response Letter (CRL) from the FDA for its supplemental Biologic License Application for a subcutaneous delivery method of TYSABRI (natalizumab) to treat multiple sclerosis. The FDA's response indicates the filing cannot be approved as it stands. Biogen is reviewing the CRL and will decide on further actions. However, the intravenous administration of TYSABRI remains unaffected and continues to be a viable treatment for relapsing MS. The subcutaneous delivery was approved in March 2021 by the European Commission, and Biogen intends to pursue regulatory filings in other countries.
