Tysabri (natalizumab)
BLA #125104
REMS last update: 10/14/2016

What is the purpose of the REMS?

The goals of the Tysabri REMS are:

  1. To inform prescribers, infusion center healthcare providers, and patients about the risk of progressive multifocal leukoencephalopathy (PML) associated with TYSABRI including the increased risk of PML with longer treatment duration, prior immunosuppressant use and the presence of anti-JCV antibodies.
  2. To warn against concurrent use with antineoplastic, immunosuppressant, or immunomodulating agents, and in patients who are immunocompromised.
  3. To promote early diagnosis of PML and timely discontinuation of TYSABRI in the event of suspected PML.

What do participants need to know?

Lower PML-related mortality and morbidity have been reported following Tysabri discontinuation in patients with PML who were initially asymptomatic compared to patients with PML who had characteristic clinical signs and symptoms at diagnosis” within Section 5.1—Progressive Multifocal Leukoencephalopathy of the prescribing information.
  2. Change the sponsor name change from Biogen Idec to Biogen in the REMS document and all REMS materials.
  3. Update the list of immunosuppressants, antineoplastics, and immunomodulators with a recently approved medication for multiple sclerosis (Zinbryta [daclizumab]) in the REMS materials.
  4. Change the signature statements to enable certified prescribers to delegate the completion of the forms to individuals within their office who are not certified prescribers in the reauthorization and discontinuation status forms.
