Study Arms:
- R-CHOP- blinatumomab (Type: EXPERIMENTAL): Patients will first undergo a prior debulking therapy including 2 cycles of R-CHOP.~At Day1 (D1) : Rituximab 375 mg/m² Intravenous (IV) + Cyclophosphamide 750 mg/m² IV + Doxorubicin 50 mg/m² IV + Vincristine 1.4 mg/m² IV.~From D1 to D5 : Prednisone 60 mg/m² Per Os (PO). Patients with CR and no measurable lesion left will not be treated further in the setting of the present trial. All the remaining patients will be continuing and treating on study with a single cycle of blinatumomab induction therapy : Blinatumomab at 9 μg/d IV by continuous vein infusion from day 1-7, 28 μg/d from day 8-14 and 112 μg/d from day 15-56.~Patients who achieve an objective response after induction are eligible to receive one further optional cycle of blinatumomab consolidation : blinatumomab 9 μg/d IV by continuous vein infusion from day 1-7, 28 μg/d from day 8-14 and 112 μg/day IV from day 15-28.

Based on this trial design, predict the completion outcome and termination type (if applicable).
