Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Obinutuzumab

Drug: Obinutuzumab
Chemotherapy will be conducted according to PALG ALL7 protocol, which is considered a standard of care in Poland. Patients in experimental arm will receive obinutuzumab .Obinutuzumab: 1000 mg i.v. (first infusion divided into 100 mg on d. 1 and 900 mg on d. 2).
Active Comparator: Rituximab
Patients in reference arm (Arm A) will receive rituximab. Patients in experimental arm (Arm B) will receive obinutuzumab instead of rituximab in the same time-points.
Drug: Rituximab
Chemotherapy will be conducted according to PALG ALL7 protocol, which is considered a standard of care in Poland.The protocol includes the use of rituximab in combination chemotherapy. Rituximab: 375 mg/m2 intravenously (i.v.)
