简要总结
This is a prospective, multicenter, single arm, phase II trial in patients with ≥ 18 and <65 years with poor-prognosis (IPI ≥ 2) and newly diagnosed ABC-DLBCL.
Aim of the study is to assess the efficacy and the safety of R-CHOP in combination with ibrutinib for 6 cycles followed by ibrutinib maintenance for 18 months in ABC-DLBCL patients achieving at least a PR after the induction phase
详细描述
Step 1 - Screening phase If central review will confirm and define the diagnosis of ABC-DLBCL according the COO, eligible patients will have to sign an additional informed consent prior to receive the study subsequent treatment.
Step 2 - study treatment phases Induction phase: 5 courses of R-CHOP every 21 days combined with ibrutinib (560 mg/day, continuously).
Maintenance phase: patients achieving a CR or a PR after 5 courses of RI-CHOP21 will enter the maintenance phase with ibrutinib (560 mg/day, continuously) for 18 months.
Radiotherapy could be delivered as consolidation treatment at the end of R-chemotherapy, according to Institution local clinical practice, in patients with focal PET positive residual disease and to bone extranodal lesions or scrotum, if testicular involvement irrespective of initial tumor diameter.
