2.3 Administration
Preparing Patient for KYMRIAH Administration with Lymphodepletion
- Confirm availability of KYMRIAH prior to starting the lymphodepleting regimen.
Pediatric and Young Adult Relapsed or Refractory (r/r) B-cell Acute Lymphoblastic Leukemia (ALL)
Lymphodepleting chemotherapy: Fludarabine (30 mg/m2 intravenous daily for 4 days) and cyclophosphamide (500 mg/m2 intravenous daily for 2 days starting with the first dose of fludarabine). Infuse KYMRIAH 2 to 14 days after completion of the lymphodepleting chemotherapy.
Adult Relapsed or Refractory (r/r) Diffuse Large B-cell lymphoma (DLBCL)
• Lymphodepleting chemotherapy: Fludarabine (25 mg/m2 i.v. daily for 3 days) and cyclophosphamide (250 mg/m2 IV daily for 3 days starting with the first dose of fludarabine).
• Alternate lymphodepleting chemotherapy: bendamustine 90 mg/m2 i.v. daily for 2 days if a patient experienced a previous Grade 4 hemorrhagic cystitis with cyclophosphamide or demonstrates resistance to a previous cyclophosphamide containing regimen.
• Infuse KYMRIAH 2 to 11 days after completion of the lymphodepleting chemotherapy.
• Lymphodepleting chemotherapy may be omitted if a patient’s white blood cell (WBC) count is less than or equal to 1 x 109/L within 1 week prior to KYMRIAH infusion.
Preparation of KYMRIAH for Infusion and Administration
Delay the infusion of KYMRIAH if a patient has unresolved serious adverse reactions (including pulmonary reactions, cardiac reactions, or hypotension) from preceding chemotherapies, active uncontrolled infection, active graft versus host disease (GVHD), or worsening of leukemia burden following lymphodepleting chemotherapy [see Warnings and Precautions (5.1)].
A KYMRIAH dose may be contained in up to three cryopreserved patient specific infusion bags. Verify the number of bags received for the dose of KYMRIAH with the Certificate of Conformance (CoC) and Certificate of Analysis (CoA). Coordinate the timing of thaw of KYMRIAH and infusion in the following manner. Confirm the infusion time in advance, and adjust the start time for thaw so that KYMRIAH is available for infusion when the recipient is ready. If more than one bag has been received for the treatment dose, thaw 1 bag at a time. Wait to thaw/infuse the next bag until it is determined t
