This phase I trial is studying the side effects and best dose of flavopiridol in treating patients with relapsed or refractory acute myeloid leukemia, acute lymphoblastic leukemia, or chronic myelogenous leukemia. Drugs used in chemotherapy, such as flavopiridol, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.

Study summary:

PRIMARY OBJECTIVES: I. To determine the maximal tolerable dose of flavopiridol in relapsed or refractory acute leukemia in adults (Stratum 1) and children (Stratum 2). II. To define the qualitative and quantitative toxicities of flavopiridol in regard to organ specificity, time course, predictability, and reversibility. III. To determine the preliminary clinical activity of flavopiridol in adults (Stratum 1) and children (Stratum 2) using this novel schedule in acute leukemia. IV. To evaluate the plasma and cellular pharmacokinetics of flavopiridol in patients enrolled on this study. SECONDARY OBJECTIVES: I. To measure pharmacodynamic measurements including effects on cell cycle; down modulation of bcl-2, mcl-1, XIAP, bax, RNA polymerase II phosphorylation; and signaling via the VEGF (VEGF, VEGF-R1, VEGF-R2, HIF-1), NF-Kappa B pathway, and PI3kinase pathway; and correlate with Css and other pharmacokinetic features. II. To assess drug induced apoptosis of acute leukemia cells in vitro and subsequent relationship to clinical response based upon Css of flavopiridol attained in vivo. II. To determine if increase in inflammatory cytokines (TNF-alpha, gamma-IFN, IL-6 and IL-8) correlate with pharmacokinetics, pharmacodynamics, laboratory (decrease in serum albumin) and clinical (hypotension observed with the first administration of flavopiridol) parameters of treatment. OUTLINE: This is a dose-escalation study. Patients are stratified according to age group (adult [≥ 18 years] vs pediatric [1-17 years]). Patients receive flavopiridol intravenously (IV) over 30 minutes followed by a 4-hour infusion on days 1-3. Treatment repeats every 21 days for up to 6 courses in the absence of unacceptable toxicity or disease progression. Cohorts of 3-6 patients receive escalating doses of flavopiridol 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 up every 2 months for 1 year and then every 6 months for 4 years.
