Conditions

Adult Acute Myeloid Leukemia With 11q23 (MLL) Abnormalities, Adult Acute Myeloid Leukemia With Inv(16)(p13;q22), Adult Acute Myeloid Leukemia With t(16;16)(p13;q22), Adult Acute Myeloid Leukemia With t(8;21)(q22;q22), Secondary Acute Myeloid Leukemia, Untreated Adult Acute Myeloid Leukemia

Brief summary

Phase I trial to study the effectiveness of combining oblimersen with cytarabine and daunorubicin in treating older patients who have previously untreated acute myeloid leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Oblimersen may help cytarabine and daunorubicin kill more cancer cells by making them more sensitive to chemotherapy.

Detailed description

OBJECTIVES: I. Determine the maximum tolerated dose of daunorubicin in combination with cytarabine and oblimersen in older patients with previously untreated acute myeloid leukemia. II. Determine the qualitative and quantitative toxic effects of this regimen in these patients. III. Determine the pharmacokinetics of oblimersen in this regimen in these patients. IV. Determine the disease-free survival and overall survival of patients treated with this regimen. V. Assess the spontaneous rate of apoptosis in leukemic blasts in patients before and after initiation of treatment with oblimersen. VI. Determine therapeutic response (complete remission) in patients treated with this regimen. OUTLINE: This is a dose-escalation study of daunorubicin. Patients are stratified according to disease status (primary vs secondary). INDUCTION THERAPY: Patients receive oblimersen (G3139) IV continuously on days 1-10 and cytarabine IV continuously on days 4-10. Patients also receive daunorubicin IV daily on days 4-6. Patients with bone marrow cellularity of at least 20% and at least 5% leukemic blasts at day 17 or evidence of refractory disease receive a second induction comprising G3139 IV continuously on days 1-8, cytarabine IV continuously on days 4-8, and daunorubicin IV on days 4-5. CONSOLIDATION THERAPY: Beginning no sooner than 14 days after hematologic recovery from induction therapy, patients receive G3139 IV continuously on days 1-8 and cytarabine IV over 4 hours on days 4-8. Patients receive a second course of consolidation therapy no sooner than 14 days after hematologic recovery from the first course. Cohorts of 3-6 patients receive escalating doses of daunorubicin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Patients are followed every 2 months for 2 years.

Design outcomes

Primary

MeasureTime frameDescription
MTD of cytarabine and daunorubicin in combination with G3139, defined as the dose level just below the dose level at which DLT is observed in 2 patients, graded according to NCI CTC version 2.0Up to day 10
Incidence of adverse events, graded according to NCI CTC version 2.0Up to 2 yearsWe will define the qualitative and quantitative toxicities in regard to organ specificity, time course, predictability, and reversibility.

Secondary

MeasureTime frame

Level of bcl-2 in circulating and/or marrow leukemic blasts before and after initiation of treatment with G3139Up to 18 weeks
Spontaneous rate of apoptosis in leukemic blasts before and after initiation of treatment with G3139Up to 18 weeks
