Bispecific T-Cell Engagers Show Promise as Later-Line Therapies for Relapsed/Refractory DLBCL
- Two bispecific T-cell engagers, epcoritamab-bysp and glofitamab-gxbm, received FDA accelerated approval in 2023 for relapsed/refractory diffuse large B-cell lymphoma, offering new treatment options for heavily pretreated patients.
- Both agents demonstrate remarkable activity with overall response rates above 50-60% and complete response rates around 40% in patients with CAR T-cell therapy failure, addressing a significant unmet medical need.
- Epcoritamab offers convenient subcutaneous administration in outpatient settings with manageable cytokine release syndrome rates below 3%, while glofitamab provides fixed-duration therapy with durable responses lasting over one year after treatment completion.
- These bispecific antibodies may challenge the paradigm that CAR T-cell therapy is the only curative option for relapsed/refractory patients, with emerging data suggesting potential for long-term disease control.
