The acute recovery period is typically for 30 days after the CAR T-cell infusion. During this time, patients must remain within two hours of Dana-Farber/Brigham and Women's Cancer Center, and must have a caregiver with them at all times to monitor for signs of fever, infection, and neurologic difficulties.

What happens before CAR T cell therapy?

A few days before CAR T cell therapy, you would receive low-dose chemotherapy. This would help prepare your body for treatment and make room for the new CAR T cells. The CAR T cells would be returned to your body. The modified CAR T cells would be put back into your body by infusion. This usually takes about 1 hour.

How do you prepare for CAR T cell therapy?
