Gemtuzumab Ozogamicin in Treating Young Patients With Newly Diagnosed Acute Myeloid Leukemia Undergoing Remission Induction and Intensification Therapy
- Conditions
- Leukemia
- Registration Number
- NCT00070174
- Lead Sponsor
- Children's Oncology Group
- Brief Summary
RATIONALE: Giving chemotherapy before a donor bone marrow transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. Also, monoclonal antibodies, such as gemtuzumab ozogamicin, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal 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.
PURPOSE: This phase II trial is studying how well gemtuzumab ozogamicin works in treating young patients who are undergoing remission induction, intensification therapy, and allogeneic bone marrow transplant for newly diagnosed acute myeloid leukemia.
- Detailed Description
OBJECTIVES:
Primary
* Determine the safety of gemtuzumab ozogamicin in children with newly diagnosed acute myeloid leukemia undergoing intensive remission induction and intensification therapy.
* Determine the complete remission rate of patients treated with this regimen.
Secondary
* Determine the feasibility of performing biological studies (e.g., FLT3-ITD and MRD) for risk group stratification in these patients.
* Determine the effect of karyotypic abnormalities on survival in patients treated with this regimen.
OUTLINE: This is a multicenter study.
* Induction I: Patients receive high-dose cytarabine (ARA-C) IV twice daily on days 1-10; daunorubicin IV over 6 hours on days 1, 3, and 5; etoposide IV over 4 hours on days 1-5; and gemtuzumab ozogamicin IV over 2 hours on day 6. Patients with CNS-negative disease receive ARA-C intrathecally (IT) on day 1. Patients with CNS-positive disease receive ARA-C IT twice weekly for 2-3 weeks. Between days 28-35, patients are evaluated. Patients achieving remission or who have no more than 20% blasts proceed to induction II.
* Induction II: Patients receive ARA-C IV twice daily on days 1-8; ARA-C IT on day 1; and daunorubicin IV and etoposide IV as in induction I. Between days 28-35 patients are evaluated. Patients achieving complete remission proceed to intensification course I.
* Intensification course I: Patients receive ARA-C IV over 1 hour twice daily on days 1-5; ARA-C IT as in induction II; and etoposide IV over 1 hour on days 1-5. Patients are evaluated at day 28. Patients with a 5/6 or 6/6 matched family donor proceed to allogeneic bone marrow transplantation. All other patients in complete remission proceed to intensification course II.
* Intensification course II: Patients receive ARA-C IV over 2 hours twice daily on days 1-4; ARA-C IT as in induction II; mitoxantrone IV over 1 hour on days 3-6; and gemtuzumab ozogamicin IV over 2 hours on day 7. Patients are evaluated on day 28 and then proceed to intensification course III.
* Intensification course III: Patients receive ARA-C IV over 3 hours twice daily on days 1, 2, 8, and 9 and asparaginase intramuscularly on days 2 and 9.
* Allogeneic bone marrow transplantation: Patients receive a preparative regimen comprising busulfan IV over 2 hours 4 times daily on days -9 to -6 and cyclophosphamide IV over 1 hour once daily on days -5 to -2. Allogeneic stem cells are infused on day 0.
* Graft-versus-host disease prophylaxis: Patients receive oral or IV cyclosporine twice daily on days -1 to 50 and methotrexate IV once daily on days 1, 3, 6, and 11.
In all courses, treatment continues in the absence of disease progression or unacceptable toxicity.
Patients are followed monthly for 6 months, every 2 months for 6 months, every 4 months for 1 year, every 6 months for 1 year, and then annually thereafter.
PROJECTED ACCRUAL: A total of 330 patients will be accrued for this study.
