Combination Chemotherapy With or Without Filgrastim and/or Tretinoin in Treating Patients With Acute Myeloid Leukemia
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. It is not yet known whether combination chemotherapy with filgrastim and/or tretinoin is more effective than combination chemotherapy alone for acute myeloid leukemia.
PURPOSE: This randomized phase III trial is studying combination chemotherapy with filgrastim and/or tretinoin to see how well they work compared to combination chemotherapy alone in treating patients with acute myeloid leukemia.
Drug: daunorubicin hydrochloride
Drug: fludarabine phosphate
|Study Design:||Allocation: Randomized
Primary Purpose: Treatment
|Official Title:||Protocol for Patients With High Risk (Resistant, Refractory, Relapsed or Adverse Cytogenetic) AML|
|Study Start Date:||August 1998|
|Study Completion Date:||December 2004|
- Compare standard induction chemotherapy with cytarabine, daunorubicin, and etoposide vs fludarabine and cytarabine in terms of achievement of remission, reasons for remission failure, duration of remission, survival, toxicity, and supportive care needs in patients with high risk acute myeloid leukemia.
- Determine if the use of filgrastim (G-CSF) or tretinoin administered during and following chemotherapy improves outcome in this patient population.
- Determine the impact of these treatment regimens on quality of life in these patients.
OUTLINE: This is a randomized, controlled, multicenter study. Patients are stratified according to type of disease (resistant vs refractory vs relapsed vs adverse cytogenetic), age (under 15 vs 15 to 29, vs 30 to 49 vs 50-59 vs 60-69 vs 70 and over), performance status, and de novo and secondary leukemia. Patients with relapsed disease are further stratified according to duration of first remission (less than 6 months vs 6 to 12 months vs 12 months and over), and prior transplantation (yes vs no).
Patients are randomized into one of two treatment arms for induction chemotherapy.
- Arm I: Patients receive induction chemotherapy consisting of cytarabine IV every 12 hours on days 1-10, daunorubicin IV on days 1, 3, and 5 and etoposide IV over 1 hour on days 1-5. Patients receive a second course of therapy with cytarabine IV every 12 hours on days 1-8 and daunorubicin and etoposide as in course 1.
- Arm II: Patients receive 2 courses of induction chemotherapy consisting of fludarabine IV over 30 minutes followed by cytarabine IV over 4 hours on days 1-5.
Patients are further randomized into one of two treatment arms for colony stimulating factor therapy.
- Arm I: Patients receive filgrastim (G-CSF) subcutaneously or IV daily beginning on day 1 of each course of induction chemotherapy and continuing until blood counts recover, for up to a maximum of 28 days.
- Arm II: Patients receive no G-CSF during and following induction chemotherapy. Patients are further randomized into one of two treatment arms for retinoid therapy.
- Arm I: Patients receive oral tretinoin daily beginning on day 1 of induction chemotherapy and continuing for up to a maximum of 90 days.
- Arm II: Patients receive no retinoid therapy during and following induction chemotherapy.
Following completion of induction chemotherapy, patients achieving complete remission and blood count recovery may receive subsequent therapy consisting of consolidation chemotherapy and/or autologous or allogeneic transplantation.
Quality of life is assessed at 3 months.
PROJECTED ACCRUAL: Approximately 800-1,000 patients will be accrued for this study within 4-5 years.
