Different Therapies in Treating Infants With Newly Diagnosed Acute Leukemia (Interfant06)

July 29, 2019 updated by: Dutch Childhood Oncology Group

International Collaborative Treatment Protocol for Infants Under One Year With Acute Lymphoblastic or Biphenotypic Leukemia

RATIONALE: Giving chemotherapy before a donor stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine, methotrexate, leucovorin, and antithymocyte globulin before and after transplant may stop this from happening. It is not yet known which treatment regimen is most effective in treating acute leukemia.

PURPOSE: This randomized clinical trial is studying how well different therapies work in treating infants with newly diagnosed acute leukemia.

Detailed Description

OBJECTIVES:

Primary

  • To compare an early intensification regimen comprising two "acute myeloid leukemia" induction therapy blocks with a standard protocol IB regimen administered directly after induction therapy in medium-risk (MR) and high-risk (HR) patients with newly diagnosed acute lymphoblastic or biphenotypic leukemia.

Secondary

  • To compare through a randomized study the role of these regimens in treating these patients.
  • To compare the overall outcome of the Interfant-06 study with outcomes in the historical control series, especially in the Interfant-99 study.
  • To compare the outcomes of low-risk, MR, or HR patients in this study with those of patients in the historical control series Interfant-99 study.
  • To study which factors have independent prognostic value in patients treated with these regimens.
  • To assess the role of stem cell transplantation in HR patients.

OUTLINE: This is a multicenter study.

  • Induction therapy:

    • Prednisone phase: Patients receive prednisone orally or IV three times daily on days 1-7 and methotrexate (MTX) and prednisolone (PRDL) intrathecally (IT) on day 1. Patients then proceed to remission induction therapy.
    • Remission induction phase: Patients receive dexamethasone (DEXA) IV or orally three times daily on days 8-28 followed by a taper to 0 over 1 week; vincristine (VCR) IV on days 8, 15, 22, and 29; cytarabine (ARA-C) IV over 30 minutes on days 8-21; daunorubicin hydrochloride (DNR) IV over 1 hour on days 8 and 9; asparaginase (ASP) IV over 1 hour or intramuscularly (IM) on days 15, 18, 22, 25, 29, and 33; MTX IT on days 1 and 29*; and ARA-C IT on day 15. Patients also receive PRDL or therapeutic hydrocortisone (HC) IT on days 1, 15, and 29.

NOTE: *Patients with CNS involvement at initial diagnosis also receive MTX IT on days 8 and 22. If CNS leukemia is still present at day 29, then patients receive weekly MTX IT until the CNS is free of leukemia.

After completion of induction therapy, patients are stratified according to risk group (low-risk [LR] vs medium-risk [MR] vs high-risk [HR]). Patients with low-risk disease are assigned to treatment arm I. Patients with MR or HR disease that is in complete remission (CR) on day 33 are randomized to 1 of 2 treatment arms. These patients are stratified according to status (MR with rearranged MLL vs MR with unknown MLL vs HR).

  • Arm I (standard therapy):

    • Protocol IB therapy (beginning on day 36 of induction therapy): Patients receive cyclophosphamide (CPM) IV over 1 hour on days 1 and 29 and oral mercaptopurine (MP) on days 1-28; ARA-C IV on days 3-6, 10-13, 17-20, and 24-27; ARA-C IT on day 10; and MTX IT on day 24. Patients also receive PRDL or therapeutic HC IT on days 10 and 24.

    • MARMA therapy:

      • Part I: Patients receive oral MP once daily on days 1-14; high-dose (HD) MTX IV over 24 hours on days 1 and 8; leucovorin calcium orally or IV at 42, 48, and 54 hours after each dose of MTX until MTX plasma levels are safe; and MTX IT on days 2 and 9. Patients also receive PRDL or therapeutic HC IT on days 2 and 9.
      • Part II: Patients receive HD ARA-C IV over 3 hours twice daily with 12-hour intervals on days 15, 16, 22, and 23; and pegaspargase (PEG-ASP) IV over 1 hour or IM on day 23.

    • OCTADA(D) reinduction therapy:

      • Part I: At least 2 weeks after the completion of MARMA chemotherapy, patients receive oral dexamethasone (DEXA) three times daily on days 1-14, followed by a taper to 0 at day 21; oral thioguanine (TG) once daily on days 1-28; VCR IV on days 1, 8, 15, and 22; DNR IV over 1 hour on days 1, 8, 15, and 22; PEG-ASP IV over 1 hour or IM on day 1; ARA-C IV on days 2-5, 9-12, 16-19, and 23-26; and ARA-C IT on days 1 and 15. Patients also receive PRDL or therapeutic HC IT on days 1 and 15.
      • Part II: Patients receive oral TG once daily on days 36-49; ARA-C IV once daily on days 37-40 and 45-48; and CPM IV over 1 hour on days 36 and 49.
    • Maintenance therapy: At least 2 weeks after completion of the last course of OCTADA(D) chemotherapy, patients receive oral MP once daily; oral MTX once weekly; MTX IT in weeks 1 and 15; and ARA-C IT in week 8. Patients also receive PRDL or therapeutic HC IT in weeks 1, 8, and 15. Treatment continues for up to 104 weeks after initial diagnosis in the absence of disease progression or unacceptable toxicity.

  • Arm II (experimental therapy):

    • ADE therapy (beginning on day 36 of induction therapy: Patients receive ARA-C IV every 12 hours on days 1-10; DNR IV over 1 hour on days 1, 3, and 5; etoposide (VP-16) IV over 4 hours on days 1-5; and ARA-C IT on day 1. Patients also receive PRDL or therapeutic HC IT on day 1.
    • MAE therapy: Patients receive ARA-C IV every 12 hours on days 1-10; mitoxantrone hydrochloride IV over 1 hour on days 1, 3, and 5; VP-16 IV over 4 hours on days 1-5; and MTX IT on day 1. Patients also receive PRDL or therapeutic HC IT on day 1.

    • MARMA therapy:

      • Part I: Patients receive oral MP once daily on days 1-14; high-dose (HD) MTX IV over 24 hours on days 1 and 8; leucovorin calcium orally or IV at 42, 48, and 54 hours after each dose of MTX until MTX plasma levels are safe; and MTX IT on days 2 and 9. Patients also receive PRDL or therapeutic HC IT on days 2 and 9.
      • Part II: Patients receive HD ARA-C IV over 3 hours twice daily with 12-hour intervals on days 15, 16, 22, and 23; and pegaspargase (PEG-ASP) IV over 1 hour or IM on day 23.

    • OCTADA reinduction therapy:

Patients also receive PRDL or therapeutic HC IT on days 1 and 15.
      • Part II: Beginning 1 week after completion of part I, patients receive oral TG once daily on days 36-49; ARA-C IV once daily on days 37-40 and 45-48; and CPM IV over 1 hour on days 36 and 49.
    • Maintenance therapy: At least 2 weeks after completion of the last course of OCTADA chemotherapy, patients receive oral MP once daily; oral MTX once weekly; MTX IT in weeks 1 and 15; and ARA-C IT in week 8. Patients also receive PRDL or therapeutic HC IT in weeks 1, 8, and 15. Treatment continues for up to 104 weeks after initial diagnosis in the absence of disease progression or unacceptable toxicity.

All HR patients with a suitably matched donor are scheduled for allogeneic stem cell transplantation (SCT) after MARMA or before or during OCTADA(D) chemotherapy, provided they are in CR1 and no more than 8 months have elapsed since initial diagnosis.

  • Conditioning regimens for allogeneic SCT:

    • Matched sibling donor (MSD): Patients receive oral busulfan (BU) every 6 hours on days -7 to -4; CPM IV over 1 hour on days -3 to -2; and melphalan (MEL) IV over 1 hour on day -1.
    • Matched donors (MD): Patients receive oral BU every 6 hours on days -7 to -4; CPM IV over 1 hour on days -3 to -2; MEL IV over 1 hour on day -1; and anti-thymocyte globulin (ATG) IV over 4 hours on days -3 to -1.

  • Graft-Versus-Host Disease (GVHD) prophylaxis and therapy:

    • MSD: Patients receive cyclosporine (CsA) IV or orally twice daily beginning on day -1 and continuing to day 60 after SCT, followed by a taper in the absence of GVHD symptoms.
    • MD: Patients receive CsA as in group MSD; MTX IV on days 1, 3, and 6; leucovorin calcium IV on days 2, 4, and 7; and ATG IV on days -3 to -1.
  • Allogeneic SCT: Patients undergo infusion of bone marrow, peripheral blood, or cord blood hematopoietic stem cells on day 0.

After completion of study therapy, patients are followed periodically for up to 2 years.
