Clinical summary

Indications and usage TECARTUS is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of: Adult patients with relapsed or refractory mantle cell lymphoma (MCL). Adult patients with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). Standard dosing For autologous use only. For intravenous use only. Do NOT use a leukodepleting filter. Administer a lymphodepleting regimen of cyclophosphamide and fludarabine before infusion of TECARTUS. ( 2.2 ) Verify the patient's identity prior to infusion. ( 2.2 ) Premedicate with acetaminophen and diphenhydramine. ( 2.2 ) Confirm availability of tocilizumab prior to infusion. ( 2.2 , 5.1 ) Dosing of TECARTUS is based on the number of chimeric antigen receptor (CAR)-positive viable T cells. ( 2.1 ) MCL: dose is 2 × 10 6 CAR-positive viable T cells per kg body weight, with a maximum of 2 × 10 8 CAR-positive viable T cells. ( 2.1 ) ALL: dose is 1 × 10 6 CAR-positive viable T cells per kg body weight, with a maximum of 1 × 10 8 CAR-positive viable T cells. ( 2.1 ) Contraindications None. Key warnings Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome: Administer treatment per institutional standards. ( 5.3 ) Hypersensitivity Reactions: Monitor for hypersensitivity reactions during infusion. ( 5.4 ) Severe Infections: Monitor patients for signs and symptoms of infection; treat appropriately. ( 5.5 ) Prolonged Cytopenias: Patients may exhibit Grade 3 or higher cytopenias for several weeks following TECARTUS infusion. Monitor complete blood counts. ( 5.6 ) Hypogammaglobulinemia: Monitor and provide replacement therapy. ( 5.7 ) Secondary Malignancies: T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies. In the event that a secondary malignancy occurs after treatment with TECARTUS, contact Kite at 1-844-454-KITE (5483). ( 5.8 ) Pregnancy guidance Risk Summary There are no available data with TECARTUS use in pregnant women. No animal reproductive and developmental toxicity studies have been conducted with TECARTUS to assess whether TECARTUS can cause fetal harm when administered to a pregnant woman. It is not known if TECARTUS has the potential to be transferred to the fetus. Based on the mechanism of action of TECARTUS, if the transduced cells cross the placenta, they may cause fetal toxicity, including B cell lymphocytopenia. Therefore, TECARTUS is not recommended for women who are pregnant. Pregnancy after TECARTUS infusion should be discussed with the treating physician. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% – 4% and 15% – 20%, respectively.
