Large B-cell lymphomas (LBCLs) are one of the most common subtypes of non-Hodgkin lymphomas and while 1st-line standard of care has remained unchanged, the treatment paradigm has undergone a shift in recent years due to the development of novel therapeutic agents. These novel therapies include monoclonal antibody (mAb) therapies, mAb-conjugates, and chimeric antigen receptor (CAR)-T cell therapies.
