Rituximab, the first immunotherapy, and a monoclonal antibody targeting CD20, improved DLBCL overall survival when added to chemotherapy 2 decades ago. Since then, the advent of further \"naked\" monoclonal antibodies that target malignant B-cells or stimulate the immune system to kill cancer, as well as antibody-drug conjugates and bispecific antibodies have all entered the DLBCL armamentarium; with 5 antibody therapy approvals in the last 6 years alone.

Next, we will focus on the recent landmark studies that have established the use of CAR T-cell therapy as second-line treatment. While no direct prospective head-to-head comparisons exist of the 3 constructs, we will review some retrospective studies that suggest some emerging differences between the products. Lastly, we will turn our attention to the horizon as we explore some of the ongoing questions of how to best leverage the curative potential of CAR T-cell therapy for the most effective management of LBCL.
