Abstract
In their paper, the authors present their experience with the use of chimeric antigen receptor T cells targeting CD7 as a bridge to allogeneic haematopoietic cell transplantation in patients with relapsed/refractory T-cell acute lymphoblastic leukaemia/lymphoblastic lymphoma. Commentary on: Cao et al. A safety and efficacy study of allogeneic haematopoietic stem cell transplantation for refractory and relapsed T-cell acute lymphoblastic leukaemia/lymphoblastic lymphoma patients who achieved complete remission after autologous CD7 chimeric antigen receptor T-cell therapy. Br J Haematol 2024;204:2351-2364.

Bone Marrow Transplant 2024; 59:162-170. [PMID: 38102213 DOI: 10.1038/s41409-023-02176-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 11/29/2023] [Accepted: 12/01/2023] [Indexed: 12/17/2023]
Abstract
In recent years, chimeric antigen receptor T-cell therapy (CAR T) has revolutionized the treatment landscape for large B cell lymphoma (LBCL), demonstrating remarkable efficacy and ushering a new era of therapeutic possibilities. However, a subset of patients may not achieve the desired response with CAR T. This review examines strategies aimed at optimizing outcomes for patients who relapse or progress after CAR T. Available data on utilization of CD19-directed monoclonal antibodies and antibody drug conjugates have shown limited efficacy in this setting. Moreover, bispecific antibodies have also emerged as an alternative therapy in relapsed and or refractory LBCL, but long-term follow up treated cases post-CAR T failure are lacking. Several observational studies have shown efficacy of allogeneic hematopoietic cell transplantation, but attainment of a complete remission prior to allografting is a prerequisite to achieve durable remissions. As we navigate the intricate landscape of treatment of post CAR T failure, it becomes evident that this represents a therapeutic challenge which necessitates a multifaceted approach.

How to integrate CD19 specific chimeric antigen receptor T cells with other CD19 targeting agents in diffuse large B-cell lymphoma? Hematol Oncol 2024; 42:e3237. [PMID: 37937474 DOI: 10.1002/hon.3237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 10/12/2023] [Accepted: 10/13/2023] [Indexed: 11/09/2023]
Abstract
About one third of patients with diffuse large B-cell lymphoma (DLBCL) have a relapsing/refractory (R/R) disease after first line chemo-immunotherapy, with particularly poor outcomes observed in patients with primary refractory disease and early relapse. CD19 specific chimeric antigen receptor (CAR) T cell therapy is a game changer that results in durable and complete response rates in almost half of the patients with R/R DLBCL. Other emerging CD19-targeting therapies include monoclonal antibodies, bispecific antibodies and targeting antibody-drug conjugates, which also show encouraging results. However, the timing and sequencing of different anti-CD19-targeting agents and how they might interfere with subsequent CAR T cell treatment is still unclear. In this review, we summarize the results of the pivotal clinical trials as well as evidence from real-world series of the use of different CD19-targeting approved agents. We discuss the effect of various therapies on CD19 expression and its implications for treatment sequencing.
