ClinConnect Summary

This clinical trial is studying two treatment options—Epcor-only (Epcoritamab alone) and Epcor-R2 (Epcoritamab combined with two other medications, lenalidomide and rituximab)—to see how effective they are in preventing the return of large B-cell lymphoma in patients who have recently undergone CAR T-cell therapy. The focus is on patients who have shown some improvement but still have detectable cancer cells in their blood, known as Minimal Residual Disease (MRD). The trial aims to find out if these treatments can help keep the cancer from coming back.

To be eligible for the trial, participants need to be at least 18 years old and have a diagnosis of relapsed or refractory large B-cell lymphoma. They should have received anti-CD19 CAR T-cell therapy recently and have shown a partial or complete response to treatment. Participants will undergo regular check-ups and tests to monitor their health throughout the study. It's important for potential participants to discuss any existing health issues with their doctor, as certain conditions may prevent them from joining the trial. Overall, this study hopes to improve treatment options for patients facing this challenging cancer.

• • 7. Adequate haematological function documented within 7 days prior to randomisation
• • 8. Adequate cardiac function.
• • 9. Adequate renal function, documented within 7 days prior to randomisation
• • 10. Adequate hepatic function documented within 7 days prior to randomisation
• • 11. Complete resolution of cytokine release syndrome (CRS), macrophage-activation syndrome (MAS)/haemophagocytic lymphohistiocytosis (HLH) or immune effector cell-associated neurotoxicity syndrome (ICANS) related to prior CAR T-cell therapy.
• • 12. Female patients of childbearing potential (FCBP) must be willing to follow the contraceptive method/procedure as outline in the PICF
• • 13. Sexually active males must agree to use a condom during sexual contact with a pregnant female or a FCBP for the course of the study through to 4 months after the last dose of epcoritamab, even if he has undergone a successful vasectomy
• • 14. Women must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction. Men must also not donate sperm during the trial and for 4 months after receiving the last dose of epcoritamab
• • 15. The patient understands the purpose of the trial and procedures required for the trial which includes compliance with the protocol requirements and restrictions listed in the PICF and in this protocol
• • Exclusion Criteria
• • 1. A history of Grade 4 CRS or ICANS related to prior CAR T-cell therapy
• • 2. Patients whose lymphoma is known to be CD20 negative on the most recent biopsy prior to CAR T-cell therapy
• • 3. Ongoing active bacterial, viral, fungal, mycobacterial, parasitic, or other infection requiring systemic treatment
• • 4. Progression or relapse within 3 months after a regimen containing a bispecific antibody targeting CD3 and CD20

• • 6. Active secondary CNS involvement of lymphoma at time of screening
• • 7. A known history or current autoimmune disease or other diseases resulting in permanent immunosuppression

• • 13. Exposed to live or live attenuated vaccine within 4 weeks prior to signing the PICF.
• • 14. Women who are pregnant or lactating
• • 15. Known hypersensitivity to epcoritamab, lenalidomide, rituximab, tocilizumab or their excipients
• • 16. Presence of any psychological, social or geographical or other condition for which participation would not be in the best interest of the patient
