Condition(s) targeted: 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

Intervention: oblimersen sodium (Biological); cytarabine (Drug); daunorubicin hydrochloride (Drug); laboratory biomarker analysis (Other); pharmacological study (Other)

Phase: Phase 1

Status: Completed

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.

Clinical Details

Official title: A Phase I Study of G3139 ( NSC # 683428) in Combination With Cytarabine and Daunorubicin in Previously Untreated Patients With Acute Myeloid Leukemia (AML)>= 60 Years of Age

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

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 2.0

Incidence of adverse events, graded according to NCI CTC version 2.0

Secondary outcome:

Pharmacokinetics of G3139

Level of bcl-2 in circulating and/or marrow leukemic blasts before and after initiation of treatment with G3139

Spontaneous rate of apoptosis in leukemic blasts before and after initiation of treatment with G3139

Incidence of therapeutic response (complete remission [CR])

Disease-free survival

Overall survival

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.
