CAR T cells or allogeneic transplantation as standard of care for advanced large B-cell lymphoma: an intent-to-treat comparison.

CD19-directed chimeric antigen receptor (CAR) T-cell treatment has evolved as standard of care (SOC) for multiply relapsed/refractory (R/R) large B-cell lymphoma (LBCL). However, its potential benefit over allogeneic hematopoietic cell transplantation (alloHCT) remains unclear. We compared outcomes with both types of cellular immunotherapy (CI) by intention to treat (ITT).

Feasibility and Safety of CD19 Chimeric Antigen Receptor T Cell Treatment for B Cell Lymphoma Relapse after Allogeneic Hematopoietic Stem Cell Transplantation.

Although CD19-directed chimeric antigen receptor (CAR) T cells have been successfully used after a preceding allogeneic stem cell transplant (alloHCT) in patients with acute lymphoblastic leukemia, little is known about the feasibility and outcome of CAR T cell treatment in patients who have been previously allotransplanted for lymphoma. In a single-center retrospective analysis, course and outcome of all allografted patients treated with CD19 CAR constructs for B cell lymphoma between October 2018 and November 2019 were studied. CAR therapy consisted either of a third-generation CAR (HD-CAR-1) or of commercially manufactured axicabtagene ciloleucel (axi-cel; Gilead, Santa Monica, U.
