CAR T-cell therapy for relapse after autologous SCT

In the event of disease relapse after autologous SCT, many patients receive consolidation with CAR T-cell therapy.

Multiple trials describe patients with refractory large B-cell lymphoma who underwent an infusion of T cells that were engineered to express a CAR to target the CD19 antigen expressed on the malignant B cells using three different constructs: axi-cel, tisagenlecleucel, and liso-cel.[31-35] Each study reported a complete response rate of 50% to 60% and a 2-year OS rate of 40% to 50%, but the long-term durability of response has yet to be determined in these highly-selected patients.[31-33][Level of evidence C3] This therapy is an option for patients with otherwise refractory or resistant disease. These results have been verified off-study in two reports that included 397 patients treated after U.S. Food and Drug Administration (FDA) approval.[36,37][Level of evidence C3] The highest risk patients who respond adequately may receive a subsequent allogeneic SCT consolidation in some cases if eligible.

ASCO has compiled guidelines for the management of adverse events in patients treated with CAR T-cell therapy.[11]
