Background: Bispecific antibodies are effective for relapsed/refractory B-cell lymphoma patients even after CAR-T therapy.
Methods: Peripheral blood CAR-T kinetics and functional analysis in vivo were carried out pre- and post-epcoritamab infusion in B-cell lymphoma patients relapsing after CAR-T therapy.
Results: CAR copy numbers spiked at relapse and rose again following epcoritamab administration. Expression levels of CAR-T exhaustion markers did not increase, whereas perforin and granzyme B expression increased after epcoritamab induction.
Conclusion: Early epcoritamab administration without cytotoxic agents at relapse after CAR-T therapy revives CAR-T cell numbers and cytotoxicity, which may potentially lead to favorable clinical outcomes.

T-cell-engaging antibodies are a promising new type of treatment for patients with refractory or relapsed (R/R) diffuse large B-cell lymphoma, which has changed the prognosis and evolution of these patients in clinical trials. Bispecific antibodies (BsAbs) bind to two different targets (B and T lymphocytes) at the same time and in this way mimic the action of CAR (chimeric antigen receptor) T-cells. They are the T-cell-engaging antibodies most used in practice and are a solution for patients who do not respond to second- or later-line therapies, including chemoimmunotherapy, followed by salvage chemotherapy and hematopoietic stem cell transplantation.

Introduction: Relapsed or refractory diffuse large B-cell lymphoma (DLBCL) poses considerable treatment challenges, with disheartening odds of long-term survival. Numerous strategies exist, including non-cross-resistant combination chemoimmunotherapy regimens, autologous stem cell transplantation, and chimeric antigen receptor (CAR) T-cell therapy, but some patients are not appropriate candidates or cannot sustain response to treatment. Epcoritamab, a bispecific CD20-directed CD3 T-cell engager, has been given accelerated approval by the US Food and Drug Administration for relapsed or refractory DLBCL.

Antibody-drug conjugates (ADCs) and T-cell-dependent bispecific antibodies (TDBs) show single-agent efficacy in relapsed/refractory (R/R) lymphomas. While coadministering therapeutics with orthogonal mechanisms of action may safely enhance efficacy, testing every potential combination regimen is infeasible in the clinic. An integrated quantitative systems pharmacology model of a CD19-targeted ADC and CD3/CD20-targeted TDBs was developed to predict combination regimen efficacy in R/R diffuse large B-cell lymphoma (DLBCL).

Despite advancements in treatment for B-cell non-Hodgkin lymphoma (B-NHL) in recent decades, many patients still relapse or are refractory to treatment, which represents a high unmet medical need. Novel CD20 × CD3 T-cell-engaging bispecific antibodies (bsAbs) have created a new paradigm for the treatment of B-NHL. Pivotal studies of four CD20 × CD3 bsAbs, mosunetuzumab, glofitamab, epcoritamab, and odronextamab, as monotherapy, have demonstrated robust responses with generally manageable safety profiles in patients with relapsed or refractory follicular lymphoma and diffuse large B-cell lymphoma after ≥ 2 lines of systemic therapy.
