What is Zinbryta?

Daclizumab (trade name Zinbryta) is a humanized monoclonal antibody drug that is once-monthly self-injected into the persons thigh muscle for treatment of relapsing multiple sclerosis (MS).  Zinbryta was first approved by the FDA in 1997 and used to prevent acute rejection of kidney transplants.

The second FDA approval took place in May 2016 (including a boxed warning due to risks of liver damage) for the treatment of relapsing multiple sclerosis in adults.  It’s estimated that over 8,000 patients have been treated with Zinbryta worldwide.

Zinbryta was brought to market by AbbVie Inc for sale in America.  Biogen is the seller in Switzerland, Canada and European Union.  Since it was the first of its kind, a humanized antibody, its annual sales were forecasted to be between $100 million and $250 million.

Zinbryta Recall – Removed from the Market.

Last November European regulators voiced safety concerns about the risks of possible serious liver damage.  Biogen pulled Zinbryta from the market April 30, 2018 because of potential adverse events such as liver damage, inflammatory brain disease, encephalitis, seizures, and even death.

Biogen’s executive vice president and chief medical officer Dr. Alfred Sandrock issued this statement:  “Biogen believes the voluntary worldwide withdrawal of Zinbryta, a treatment for relapsing multiple sclerosis, is in the best interest of patients.” He further states:  “Biogen and AbbVie continue to prioritize patient safety and the care of multiple sclerosis patients worldwide.”Zinbryta Class Action Lawsuit

The company explained in its press release that it will work with the FDA and EMA as well as doctors worldwide in removing Zinbryta from the market.

The European Medicines Agency (EMA), the EU version of our FDA, issued a press release on February 3, 2018; the following is a direct excerpt from it:

EMA urgently reviewing multiple sclerosis medicine Zinbryta following cases of inflammatory brain disorders

Medicine to be voluntarily withdrawn from the market by the company

The European Medicines Agency (EMA) has started an urgent review of the multiple sclerosis medicine Zinbryta (daclizumab) following 7 cases of serious inflammatory brain disorders in Germany, including encephalitis and meningoencephalitis, and one case in Spain.European Medicines Agency Zinbryta

In parallel to the start of the review, the company that markets Zinbryta (Biogen Idec Ltd) has informed EMA of its intention to voluntarily withdraw the medicine’s marketing authorisations.

Doctors in the EU will be contacted directly in the coming days with further information. Until then EMA advises that:

  • doctors should not start new patients on Zinbryta;
  • doctors should review patients currently treated with Zinbryta and initiate alternative therapy, as soon as possible;
  • patients must not stop their medication without discussing with their doctor;
  • patients who have any questions should talk to their doctor.

The company has also informed EMA of its decision to stop ongoing clinical studies with Zinbryta in the EU. Patients in clinical studies who have any question should contact the doctor treating them in their study.  EMA will communicate further as necessary.
