Zinbryta (daclizumab), a Therapy for Relapsing MS, is Withdrawn from Market

• Biogen and AbbVie have announced the voluntary withdrawal Zinbryta ™ (daclizumab) from the worldwide market.
• Zinbryta is an immune-modulating therapy that was approved in 2016 for people with relapsing MS and generally reserved for people who had an inadequate response to two or more MS therapies.
• According to a company press release, the European Medicines Agency had raised new safety concerns related to reports of inflammation of the brain or its surrounding tissues (inflammatory encephalitis and meningoencephalitis) among people taking Zinbryta.
• Individuals currently taking Zinbryta should contact their healthcare providers to determine alternative treatment options, and to continue safety monitoring. According to the medication guide, this would include monthly blood tests to monitor liver function for up to six months after the last dose.
