CyBeR Association in Relapsed/Refractory DLBCL

Summary

Forty percent of patients with diffuse large B cell lymphoma (DLBCL) have primary refractory or relapsed disease (R/R). For these fit patients, standard treatment in second line therapy is high dose therapy with autologous stem cell transplantation (ASCT). In 48% of DLBCL no ASCT is possible due to progressive disease. For these patients or ineligible to transplantation patients, salvage therapy is often rituximab-gemcitabine-oxaliplatine regimen with an overall response rate (ORR) about 50%. Bendamustine in combination with rituximab, used as a single agent in the setting of R/R DLBCL patients, have shown an ORR of 62.7% and 45.8% with a good safety profile. Bendamustine and cytarabine (BAC) showed high synergy in inducing cell death in mantle cell lymphoma and DLBCL cell lines. In a recent phase II study, the combination of cytarabine with Rituximab and Bendamustine (R-BAC) in patients with mantle cell lymphoma who were previously untreated, refractory or relapsed was evaluated. The efficacy and safety of the R-BAC association will be evaluated in this phase II trial enrolling 78 patients with relapsed or refractory DLBCL.
