Risk Evaluation and Mitigation Strategy


REMS Safety Information

A Risk Evaluation and Mitigation Strategy (REMS) is a program to manage known or potential serious risks associated with a drug product and is required by the Food and Drug Administration (FDA) to ensure that the benefits of the drug outweigh its risks. The FDA has required a REMS for Kymriah™ (tisagenlecleucel).




Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving KYMRIAH. Do not administer KYMRIAH to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab.


Neurological toxicities, which may be severe or life-threatening, can occur following treatment with KYMRIAH, including concurrently with CRS. Monitor for neurological events after treatment with KYMRIAH. Provide supportive care as needed.


KYMRIAH is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the KYMRIAH REMS. 


Goals of the REMS


The goals of the Kymriah™ (tisagenlecleucel) REMS Program are to mitigate the risks of cytokine release syndrome (CRS) and neurological toxicities by:


  • Ensuring that hospitals and their associated clinics that dispense Kymriah are specially certified and have on-site, immediate access to tocilizumab.

  • Ensuring those who prescribe, dispense, or administer Kymriah are aware of how to manage the risks of cytokine release syndrome and neurological toxicities. 


Kymriah is only available at select treatment centers.  For more information, please call the REMS Call Center at 1-844-4KYMRIAH (1-844-459-6742).


To learn more about Kymriah and its serious risks and clinical manifestations, read the Prescribing Information and the Medication Guide.


The Kymriah REMS Program Patient Wallet Card, the Kymriah REMS Live Training Program Slides, and Kymriah REMS Program Knowledge Assessment can be ordered through the REMS Call Center at 1-844-4KYMRIAH (1-844-459-6742). A laminated Kymriah REMS Program Patient Wallet Card is also available from the REMS Call Center.
