Brief Summary:

The trial B-NHL 2013 is a collaborative prospective, multi-national, multi-center, randomized trial with participating centers of the NHL-BFM group (Austria, Switzerland, Czech Republic, Germany) and the Scandinavian NOPHO group (Denmark, Finland, Norway, Sweden). The aim of the trial is to evaluate the role of rituximab in the treatment of mature aggressive B-cell Non-Hodgkin lymphoma and leukemia (B-NHL and B-AL) in children and adolescents.

The following primary study questions are going to be analyzed:

  • the effectiveness (event-free survival) in pediatric patients with very limited mature B-NHL (R1 and R2 stage I and II) of substituting anthracyclines by the rituximab window without compromising survival rates.
  • the effectiveness (event-free survival) in pediatric patients with limited mature B-NHL (R2 stage III) randomly assigned to receive the rituximab window plus standard chemotherapy or standard chemotherapy without the rituximab window.
  • the effectiveness (event-free survival) and the immune reconstitution (recovery of CD19+ B-cells, IR) in pediatric patients with advanced mature B-NHL/B-AL (R3 and R4 incl. R4 CNS+) treated with BFM-type chemotherapy and randomly assigned schedules of one versus seven doses rituximab.

Secondary study questions will address

  • additional parameters for immune reconstitution, lymphocyte subpopulations, immunoglobulin levels, vaccination titers and infection rates
  • kinetics of immune reconstitution after treatment
  • adverse event and severe adverse event profile
  • inter-individual variability of rituximab response
  • role of different mechanisms of action of rituximab in advanced B-NHL/B-AL

Condition or disease Intervention/treatment Phase
Mature B-cell Non-Hodgkin Lymphoma Drug: Rituximab window Drug: Additional doses of Rituximab Drug: Cyclophosphamide Drug: Cytarabine Drug: Dexamethasone Drug: Doxorubicin hydrochloride Drug: Vindesine Sulfate Drug: Etoposide Drug: Ifosfamide Drug: Methotrexate Drug: Prednisolone Drug: Vincristine Phase 3

Detailed Description:

Risk group stratification:

R1/R2 stage I+II:

  • R1: resection status: complete
  • R2: resection status: incomplete, stage I and II

R2 III:

- R 2: resection status: incomplete, stage III and LDH < 2 x ULN (according to local reference value for adults)

R3/R4:

  • R3: resection status: incomplete, stage III and LDH ≥ 2 x ULN but < 4 x ULN or stage IV/B-AL and LDH < 4 x ULN and CNS negative
  • R4: resection status: incomplete, Stage III and LDH ≥ 4 x ULN or stage IV/B-AL and LDH ≥ 4 x ULN and CNS negative
  • R4 CNS +: stage IV/B-AL and CNS positive

For patients with very limited disease (R1/R2 stage I/II), the addition of rituximab might allow the omission of anthracyclines without jeopardizing survival rates but reducing acute and long term toxicities. In this treatment arm, it is tested whether the event-free survival is similar to that of the historical control when all patients receive one dose of rituximab as monotherapeutic agent in the rituximab window R five days prior to the start of standard chemotherapy as a substitute for anthracyclines.

For patients with limited disease (R2 stage III) it is tested whether the event-free survival can be improved by adding rituximab to the standard chemotherapy. Two different treatment regimens will be evaluated in a randomized design: Patients in the standard arm will receive the standard chemotherapy. Patients of the rituximab plus arm will receive one dose of rituximab as monotherapeutic agent in the rituximab window R five days prior to the start of standard chemotherapy.

For patients with advanced disease (R3/R4) it is tested whether the event-free survival can be improved by adding rituximab to the standard chemotherapy. Two different rituximab regimens will be evaluated in a randomized design: Patients in the standard arm will receive one dose of rituximab as monotherapeutic agent in the rituximab window R five days prior to the start of standard chemotherapy. Patients of the rituximab plus arm will receive the rituximab window and additional six doses of rituximab added to the first four courses of chemotherapy. In addition the immune reconstitution will be analyzed comparing the effect of the two regimens of rituximab added to standard chemotherapy.

Inclusion Criteria:

  • Newly diagnosed, histological or cytological and immunological proven aggressive mature B-cell Non-Hodgkin lymphoma including Burkitt lymphoma (BL), Burkitt leukemia (B-AL), diffuse large B-cell lymphoma (DLBCL), or mature B-cell NHL not further classified according to current WHO classification.

  • diagnostics and treatment in one of the participating centers of the trial
  • no previous chemotherapy, no previous lymphoma-directed treatment. No application of steroids for more than two days during the last month
  • adequate hepatic, renal and cardiac function, except if alteration is due to lymphoma infiltration
  • signed informed consent of patient and/or parents/guardians for participation and transfer of data
  • follow-up of at least two years after initial diagnosis is expected
