Chidamide Bridging for CAR-T Therapy

"1. Chidamide monotherapy mode: Chidamide was administered for at least 6 times after leukapheresis, 10mg oral D1-4, 20mg oral D7 every 3 days to the beginning day of FC conditioning.~2. Chidamide combination mode: The combination of one or more of the following drugs in addition to chidamide is permitted: glucocorticoids, BTK inhibitors, chemotherapy, other previously used resistance drugs, etc."

Patients should be received FC regimen conditioning 3 to 5 days prior to CAR-T cell infusion. The recommended regimen is intravenous fludarabine (25-30 mg/m\^2) and cyclophosphamide (250-500 mg/m\^2) daily for 3 consecutive days. The clinician may also adjust the cleansing regimen according to the patient's actual situation.

A single infusion of CAR-transduced autologous T cells administered intravenously at a target dose of 100 × 10\^6 for Relma-cel or 2 × 10\^6/kg for Axi-cel. Other commercial CAR-T doses are determined by specific drug infusion instructions. The dose of experimental CAR-T was determined by the investigator. Infusion volume was calculated based on CAR-T cell density and recommended dose.
