Brief Summary:
CD20, the protein which is expressed on the surface of all mature B cells, is active in many B-cell lymphomas that express this molecule such as Diffuse Large B Cell Lymphoma (DLBCL), the most frequently occurring subtype of non-Hodgkin lymphomas. In clinical practice, Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone combination chemotherapy (CHOP) is still considered one of the standard treatment to DLBCL. CMAB304(Retuxira), the chimeric monoclonal antibody is designed to targeted against CD20 for treatment of lymphoma diseases. This trial aimed to observe the safety and efficacy of CMAB304, by added CMAB304 to CHOP chemotherapy regimen compared with CHOP chemotherapy alone.

Condition or disease Intervention/treatment Phase
Diffuse Large B Cell Lymphoma Drug: CHOP combined with CMAB304 Drug: CHOP, CMAB304 Phase 3

Detailed Description:
Rituximab, a chimeric anti-CD20 monoclonal antibody, has been proved valuable treatment for CD20-positive DLBCL. The combination of rituximab with CHOP has been shown to increase both survival and response rate, in comparison to CHOP alone. CMAB304(Retuxira), a biosimilar of rituximab, was developed by Shanghai CP Guojian Pharmaceutical Co.,Ltd. Previous Phase I study showed that CMAB304 was well tolerated as monotherapy and the pharmacokinetic data exhibited a non-linear profile over the dose range of 250 to 500 mg/m2. In this study, efficacy and safety of CMAB304 were evaluated in DLBCL patients.

Arm Intervention/treatment
Experimental: combination group Drug: CHOP combined with CMAB304
Patients treated with CHOP-304 undergo 1 cycle every 3 weeks, received CMAB304 at a dose of 375 mg/m2 on day 1 and CHOP on day 2 of each of the 6 cycles.
Other Name: cyclophosphamide, doxorubicin, vincristine, prednisone

Experimental: sequential group Drug: CHOP, CMAB304
First standard CHOP, then sequential CMAB304 in patients who reached a complete response or undocumented complete response at the end of treatment of 6 cycles.
Other Name: cyclophosphamide, doxorubicin, vincristine, prednisone

Primary Outcome Measures :
  1. overall response rate [ Time Frame: up to 18 weeks ]
    Tumor responses were assessed after 6 cycles of CMAB304-CHOP or 6 cycles of CHOP alone and classified as CR,CRu,PR,SD or PD.

Secondary Outcome Measures :
  1. event-free survival [ Time Frame: From date of randomization until the date of first documented progression or relapse, institution of a new anticancer treatment, or death from any cause, whichever came first, assessed up to 50 months ]
    Events were defined as disease progression or relapse, institution of a new anticancer treatment, or death from any cause.
