Brief Summary

This study is an Open-labeled, multicenter Phase II study of Bortezomib for maintenance therapy in patients with high risk diffuse large B cell lymphoma (DLBCL). Primary objective is 3 years relapse free survival (RFS) and Secondary objectives are 3 years overall survival (OS), 3 years event free survival (EFS),Toxicities profiles, Quality of Life (FACT&GOG-Ntx)

Detailed Description

High-intermediate or high risk in IPI has a long-term chance of cure in the range about 50% in patients with DLBCL treated by R-CHOP. These high risk patients should be considered for additional new treatment to standard R-CHOP or investigational approaches in the context of clinical trials that are designed to ensure that potentially curative therapy.

Bortezomib has shown activity in vitro against DLBCL-derived cell lines. Single-agent bortezomib or chemotherapy combined bortezomib are feasible in follicular, mantle cell, marginal zone lymphoma and DLBCL with manageable toxicities. Bortezomib enhances the activity of chemotherapy in non-GCB but not GCB DLBCL, and provide a rational therapeutic approach based on genetically distinct DLBCL subtypes.

High CR/CRu rate with bortezomib with standard R-CHOP suggests it may be a good backbone for additional maintenance leading to durable response. However, there is no study of bortezomib as maintenance therapy after treated with R-CHOP in high risk patients with DLBCL. So we applied additional bortezomib as maintenance therapy in order to assess improving efficacy and survival rates in high risk patients with non-GCB DLBCL who had been confirmed CR after treated with R-CHOP.
