Itacitinib Pre-modulation in DLBCL Receiving CAR T Cell Therapy

Participants start itacitinib 200 mg PO once daily within 1-4 days after apheresis while awaiting CAR-T-cell manufacturing, which is expected to take approximately from week -4 until day -7. Patients will remain on itacitinib 200 mg PO once daily from initiation until 30 days post-CAR-T-cell therapy (Day 30) including throughout lymphodepleting chemotherapy period (Days -5, -4, -3) and axi-cel infusion (Day 0) for a total of approximately 58 doses.

Yescarta is an autologous anti-CD19 CAR T cell therapy manufactured from the patient's own T cells, which have been extracted and then reprogrammed with CAR molecules to help the T cells recognize cancer cells. The reengineered T cells are infused back into the patient to attack the cancer.
