Overview

The prognosis of DLBCL with MYC rearrangement is dismal. Previous study showed that lenalidomide in combination with R-CHOP showed promising therapeutic activity and that R-DA EPOCH was superior compared to R-CHOP regimen in this cohort of patients. The investigators therefore design this phase I/II study to investigate the safety and efficacy of lenalidomide in combination with R-DA EPOCH in patients with untreated MYC-rearranged DLBCL.
