ZINBRYTA® (daclizumab) VOLUNTARY WITHDRAWAL
Biogen, in collaboration with our partner AbbVie, voluntarily withdrew the marketing application for ZINBRYTA in the United States on April 30, 2018.
Biogen and AbbVie believe it is in the best interest of patients to voluntarily withdraw ZINBRYTA in the United States. Given the nature and complexity of adverse events being reported with ZINBRYTA, characterizing the evolving benefit/risk profile of ZINBRYTA will not be possible going forward, given the limited number of patients being treated.
Patients that have not started a new treatment plan are advised to speak with their HCP as soon as possible. Click here to view the patient letter that Biogen has issued regarding the withdrawal and associated timing.
