Bridging chemotherapy: Adult acute lymphoblastic leukaemia

Abstract

Bridging therapy can be given after leukapheresis and before lymphodepletion during CAR-T cell manufacturing. The primary goal of bridging therapies is to prevent uncontrolled progression of the underlying disease during the manufacturing period before CAR-T cell infusion. Several studies indicate that a high tumour burden is associated with an increased risk of complications after CAR-T cell infusion (Cohen et al. 2019). Therefore, controlling the disease and even possibly decreasing the tumour burden is critical during the manufacturing period. The choice of bridging therapies is essential for the success of the procedure.
