S0919 Idarubicin, Cytarabine, and Pravastatin in Treating Patients With Relapsed Acute Myeloid Leukemia

Leukemia Clinical Trial

Official title: S0919, A Phase II Study of Idarubicin and Ara-C in Combination With Pravastatin for Poor-Risk Acute Myelogenous Leukemia

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as idarubicin and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Pravastatin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Pravastatin may also help idarubicin and cytarabine work better by making cancer cells more sensitive to the drugs. Giving idarubicin and cytarabine together with pravastatin may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving idarubicin and cytarabine together with pravastatin works in treating patients with relapsed acute myeloid leukemia (AML). ADDITIONAL BACKGROUND: S0919 was initially designed for patients with relapsed acute myeloid leukemia (AML), where the patient's preceding remission had lasted ≥ 3 months. The null response rate was 30%. The study closed to accrual on Nov 1, 2012 after meeting the defined criterion for a positive study; and the results are being submitted to the American Society of Clinical Oncology meeting. Based on the promising results from this trial, the trial has now been amended to evaluate this therapeutic regimen in poor-risk patients (patients with newly diagnosed acute myeloid leukemia (AML) arising out of myelodysplastic syndrome (MDS), primary refractory acute myeloid leukemia (AML), and relapsed acute myeloid leukemia (AML) with the patient's preceding remission lasting < 6 months).

Clinical Trial Description

COHORTS: Cohort 1 (Initial cohort: Relapsed AML with previous remission ≥ 3 months), Cohort 2 (Poor-risk cohort: MDS transformed to AML), Cohort 3 (Poor-risk cohort: Refractory or relapsed AML with previous remission < 6 months) OBJECTIVES: - To test whether the complete remission (CR) rate (including CR with incomplete recovery) in patients with relapsed acute myeloid leukemia (AML) treated with idarubicin and cytarabine in combination with pravastatin is sufficiently high to warrant a phase III investigation. - To estimate relapse-free survival and overall survival rates in these patients. - To estimate the frequency and severity of toxicities of this regimen in these patients. - To evaluate, in a preliminary manner, whether pre-study cytogenetic features correlate with response in these patients. OUTLINE: This is a multicenter study. - Induction therapy: Patients receive oral pravastatin once daily on days 1-8, idarubicin IV over 10-15 minutes on days 4-6, and cytarabine IV continuously on days 4-7. Patients achieving complete remission proceed to consolidation therapy. - Consolidation therapy: Beginning 30-60 days after the start of induction therapy, patients receive oral pravastatin once daily on days 1-6 and idarubicin IV over 10-15 minutes and cytarabine IV continuously on days 4 and 5. Treatment repeats approximately every 5 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed periodically for 5 years. ;
