A Phase II Study to Evaluate the Efficacy and Safety of F520 Combined With F007 in Patients With RR DLBCL
An Open-label, Single-arm, and Multicenter Phase Ⅱ Study to Evaluate the Efficacay and Safety of F520 Combined With F007 in Patients With Relapsed or Refractory Diffuse Large B-Cell Lymphoma.
This is an open-label, single-arm, and multicenter phase Ⅱ study designed to evaluate the efficacy and safety of F520 (PD-1) combined with F007(rituximab biosimilar) in patients with Relapsed/Refractory diffuse large B-cell lymphoma. About 62 patients with relapsed/refractory DLBCL plan to be enrolled in about 8 study sites of the study.
Primary objective:
The purpose is to evaluate the objective response rate of F520 combined with F007 in Relapsed/Refractory diffuse large B-cell lymphoma.
Secondary objective:
The purpose is to compare the safety of F520 combined with F007 in Relapsed/Refractory diffuse large B-cell lymphoma.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: F520+F007
Treatment period: F007 (375 mg/m2) administered intravenously (IV) on Day 1 of each 14-day cycle for 8 cycles. F520 (200mg) administered intravenously (IV) on Day 2 of each 14-day cycle for cycle 1. F520 (200mg) administered intravenously (IV) on Day 1 of each 14-day cycle for cycle 2 to 8. Maintenance period: F007 (375 mg/m2) administered intravenously (IV) on Day 1 of each 56-day cycle for 10 cycles. F520 (200mg) administered intravenously (IV) on Day 1/15/29/43 of each 56-day cycle for 10 cycles. |
Drug: F007 F007 is an antibody to CD20 molecules. One of the mechanisms of killing tumor cells is through antibody-dependent cell-mediated cytotoxicity (ADCC). Drug: F520 F520 is a recombinant, humanized programmed death receptor-1 (PD-1) monoclonal antibody that binds to PD-1 and prevents binding of PD-1 with programmed death ligands 1 (PD-L1) and 2 (PD-L2). |
