Summary

This phase I trial is studying the side effects and best dose of alvocidib in treating patients with metastatic or unresectable refractory solid tumors or hematologic malignancies. Drugs used in chemotherapy, such as alvocidib, work in different ways to stop cancer cells from dividing so they stop growing or die.

Detailed description

PRIMARY OBJECTIVE: I. Determine the maximum tolerated dose of flavopiridol in patients with metastatic or unresectable refractory solid tumors or hematologic malignancies. (Accrual for patients with hematologic malignancies temporarily closed as of 11/30/04) SECONDARY OBJECTIVES: I. Determine the safety profile and toxic effects of this drug in these patients. II. Determine the pharmacokinetics of this drug in these patients. III. Determine, by pharmacodynamic assays, the ability of this drug to inhibit cyclin-dependent kinase activity in tumor tissue, normal proliferating tissues, circulating tumor cells, and in plasma in these patients. IV. Determine, preliminarily, the antitumor activity of this drug in these patients. OUTLINE: This is a 2-part, dose-escalation, multicenter study. PART 1 (closed to accrual as of 8/2005): Patients receive alvocidib IV over 1 hour on days 1, 8, and 15. Cohorts of 3-6 patients receive escalating doses of alvocidib until the maximum tolerated dose (MTD)\* is determined. PART 2: Patients receive alvocidib IV over 1 hour at or below the MTD determined in part 1 and then receive a maintenance dose of alvocidib IV over 1-6 hours on days 1, 8, and 15. Cohorts of 3-6 patients receive escalating durations of the maintenance dose of alvocidib until the MTD\* is determined. An additional cohort of 10-20 patients receives alvocidib over 1 hour on days 1 and 15 at the MTD. NOTE: \*The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. In both parts, courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients are followed at 1 month and then every 2 months thereafter.
