Introduction:
The management of relapsed and/or refractory (R/R) large B-cell lymphoma (LBCL) has witnessed dramatic changes in the recent past. Despite the availability of multiple novel immunotherapies in R/R setting, there remains an unmet need for off-the-shelf therapies, particularly in patients with primary refractory, multiply relapsed disease or those experiencing cellular immunotherapy failure. To harness the power of the T-cell mediated immunity, a novel class of drugs called bispecific antibodies (BsAbs) have been developed. These BsAbs are currently under investigation both in frontline and R/R setting and hold the potential to revolutionize the management of LBCL.
Areas Covered:
This review article summarizes the currently available BsAbs, their mode of action, efficacy, and safety data for untreated and R/R LBCL. In addition, the role of these BsAbs in combination with currently available chemoimmunotherapy regimens is also discussed.
Expert Opinion:
Two BsAbs have secured FDA approval for R/R LBCL, with expected approval of more BsAbs (including in earlier treatment lines). These drugs provide a highly efficacious and relatively safe treatment option for patients with highly pretreated disease including relapse after cellular immunotherapies. In addition, these BsAbs provide a platform for chemotherapy-free regimen for older/frail patients.
