Résumé
Date de début de l'étude : 1 octobre 1999
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: I. Determine the maximum tolerated dose of fludarabine and cytarabine when combined with augmerosen (G3139) in patients with refractory or relapsed acute myeloid leukemia or acute lymphoblastic leukemia and recommend a starting dose for phase II studies. II. Determine the qualitative and quantitative toxic effects of this regimen in these patients with regard to organ specificity, time course, predictability, and reversibility. III. Document the therapeutic response in patients treated with this regimen. IV. Measure bcl-2 and related antiapoptotic and proapoptotic proteins in circulating and/or marrow leukemia cells before, during, and after treatment with G3139. V. Measure WT1 expression in leukemic blasts as a surrogate marker for minimal residual disease and correlate it with bcl-2 and related antiapoptotic and proapoptotic gene expression. VI. Determine the time required for bcl-2 levels to recover after treatment with this regimen. VII. Determine if TP53 mutations are present in leukemic blasts and how these mutations may affect expression of BAX, level of treatment induced apoptosis, and clinical endpoints. VIII. Assess apoptosis in leukemic cells before, during, and after treatment with this regimen. IX. Determine the pharmacokinetics of fludarabine and cytarabine in patients treated with this regimen. X. Perform pharmacodynamic studies of fludarabine and cytarabine on the leukemic cells of patients prior to treatment. OUTLINE: This is a dose-escalation study of fludarabine and cytarabine. Patients receive augmerosen IV continuously on days 1-10 and filgrastim (G-CSF) subcutaneously beginning on day 5 and continuing until blood counts recover. Patients receive fludarabine IV over 30 minutes followed 3.5 hours later by cytarabine IV over 4 hours on days 6-10. Patients who achieve complete response (CR) receive a second course beginning 4 weeks after completion of the first course. Patients who achieve CR and have a matched sibling or unrelated bone marrow donor may undergo allogeneic bone marrow transplantation. Cohorts of 3-6 patients receive escalating doses of fludarabine and cytarabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.
