Access through your institution Buy or subscribe The survival outcomes of patients with relapsed and/or refractory mantle-cell lymphoma (MCL) after receiving BTK inhibitors are poor; therefore, new treatment options are needed for these patients. Chimeric antigen receptor (CAR) T cell therapies targeting CD19 have demonstrated efficacy in several subtypes of B cell lymphomas, although limited results in patients with MCL have been reported. Now data from the ZUMA-2 trial reveal promising activity of the anti-CD19 CAR T cell product KTE-X19 against MCL. In ZUMA-2, KTE-X19 was successfully manufactured for 71 of 74 patients with relapsed and/or refractory MCL. A high content of leukaemic blasts in peripheral blood has been proposed as the cause of failed manufacturing of CAR T cells because it results in proportionally low numbers of non-exhausted T cells in the starting cell population. During the manufacturing of KTE-X19, circulating CD19+ malignant cells were removed in order to address this issue by reducing the potential activation and exhaustion of anti-CD19 CAR T cells in the ex vivo portion of the process.
