CD19-targeting chimeric antigen receptor (CAR)-T cell therapy has shown great efficacy in patients with relapsed/refractory non-Hodgkin lymphoma (NHL) but has been associated with serious adverse effects, such as cytokine release syndrome (CRS).
In conclusion, a reduced dose of a PD‑1 inhibitor combined with CD19 CAR‑T cells appears to be a promising treatment option for relapsed/refractory B‑NHL exhibiting high PD‑1 expression by T cells.
Strategies to augment the cytokine response to lymphodepletion could be tested in future studies of CD19 CAR T-cell immunotherapy for aggressive B-cell NHL.
The aim of this article is to provide consensus opinion from experts in the fields of hematopoietic cell transplantation, cellular immunotherapy, and lymphoma regarding key clinical questions pertinent to the use of CD19 CAR T cell products for the treatment of NHL.
Chimeric antigen receptor modified T (CAR-T) cell therapy against the CD19 antigen has revolutionized the therapeutic landscape for patients with relapsed, refractory B cell non-Hodgkin lymphoma (NHL).
The astonishing clinical success of CD19 chimeric antigen receptor (CAR) T-cell therapy has led to the approval of two second generation chimeric antigen receptors (CARs) for acute lymphoblastic leukemia (ALL) andnon-Hodgkin lymphoma (NHL).
