Combination Chemotherapy in Treating Patients With Acute Promyelocytic Leukemia
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.
PURPOSE: This phase II trial is studying how well giving combination chemotherapy works in treating patients with acute promyelocytic leukemia.
|Leukemia||Drug: arsenic trioxide Drug: cytarabine Drug: daunorubicin hydrochloride Drug: mercaptopurine Drug: methotrexate Drug: tretinoin||Phase 2|
|Study Design:||Primary Purpose: Treatment|
|Official Title:||A Pilot Study of Arsenic Trioxide-Based Consolidation Therapy for the Primary Treatment of Acute Promyelocytic Leukemia|
- Disease-free survival at 2 and 5 years after study completion
- Safety of arsenic trioxide following cytarabine and anthracycline immediately after study completion
- Validate peripheral blood real-time PCR for minimal disease monitoring as measured by real-time PCR for PML-RARalpha monthly for two years after study completion
|Study Start Date:||October 2004|
|Study Completion Date:||June 2013|
|Primary Completion Date:||December 2007 (Final data collection date for primary outcome measure)|
- Determine, preliminarily, the safety of incorporating arsenic trioxide (ATO) into cytarabine and daunorubicin hydrochloride-based consolidation therapy followed by tretinoin maintenance therapy in patients receiving induction tretinoin and daunorubicin hydrochloride with acute promyelocytic leukemia (APL) induced into remission with tretinoin and daunorubicin hydrochloride.
- Determine, preliminarily, the efficacy of this strategy in inducing and maintaining molecular remissions in patients treated with this regimen.
OUTLINE: This is a pilot, multicenter study.
- Induction therapy: Patients receive oral tretinoin twice daily on days 1-60 and daunorubicin hydrochloride IV on days 4, 6, and 8. Patients are evaluated between days 60-67 and proceed to consolidation therapy.
- Consolidation therapy: Patients receive cytarabine IV continuously on days 1-3, daunorubicin hydrochloride IV on days 1-3, and arsenic trioxide IV over 1-2 hours once daily, 5 days a week, beginning on day 8 and continuing for 6 weeks. Patients with clinical and/or cytogenic, but not molecular, remission receive additional arsenic trioxide once daily, 5 days a week, for 30 doses (6 weeks). Patients achieving clinical and molecular remission after completion of 6 or 12 weeks of arsenic trioxide proceed to maintenance therapy.
- Maintenance therapy: Patients receive oral tretinoin once daily on days 1-15. Treatment repeats every 3 months for 8 courses (2 years).
After completion of study treatment, patients are followed periodically for up to 5 years.
PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study.
