Outcome Measures

Primary Outcomes (1)

  • Proportion of patients achieving complete remission with Minimal Residual Disease level <0.1% of bone marrow cells after one course of induction treatment.

    assessed between days 33-34 since start of Induction I

Secondary Outcomes (8)

  • The proportion of patients achieving complete remission with Minimal Residual Disease level <0.01% of bone marrow cells after consolidation.

    assessed between days 20-28 since start of last course of consolidation

  • complete remission rate after Induction I

    assessed between days 33-34 since start of Induction I

  • Overall complete remission

    in 24month follow up

  • Probability of overall survival

    in 24 month follow up

  • Probability of relapse-free survival

    in 24 month follow up

  • +3 more secondary outcomes

Study Arms (2)

Obinutuzumab

EXPERIMENTAL

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: Obinutuzumab

Rituximab

ACTIVE COMPARATOR

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

Interventions

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).

Obinutuzumab

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.)
