Flavopiridol Plus Cisplatin or Carboplatin in Treating Patients With Advanced Solid Tumors

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of flavopiridol plus cisplatin or carboplatin in treating patients who have advanced solid tumors.

Detailed Description
-----------------
OBJECTIVES: Determine the maximum tolerated dose (MTD) of flavopiridol and cisplatin in patients with advanced solid tumors. (Part 1) Determine the MTD of carboplatin when combined with flavopiridol in another group of patients with advanced solid tumors. (Part 2) Determine the toxic effects of these regimens in this patient population. Determine the objective clinical response in patients treated with this regimen. Determine the pharmacokinetics of these regimens in this patient population. OUTLINE: This is a dose-escalation study of flavopiridol and cisplatin (part 1), followed by a dose-escalation study of carboplatin (part 2). Part 1: Patients receive flavopiridol IV over 24 hours. Two weeks later, patients receive cisplatin IV over 2 hours immediately followed by flavopiridol IV over 24 hours. Treatment with cisplatin/flavopiridol continues every 3 weeks in the absence of unacceptable toxicity or disease progression. Sequential dose escalation of flavopiridol is followed by sequential dose escalation of cisplatin. Cohorts of 3-6 patients receive escalating doses of flavopiridol and then cisplatin until the maximum tolerated dose (MTD) of the combination is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity. Part 2: Additional patients are accrued for part 2. Those patients receive carboplatin IV over 30 minutes immediately followed by flavopiridol IV over 24 hours. Treatment continues every 3 weeks in the absence of unacceptable toxicity or disease progression. Cohorts of 3-6 patients receive escalating doses of carboplatin until the MTD is determined. The MTD is defined as in part 1. PROJECTED ACCRUAL: Approximately 36-48 patients will be accrued for this study within 2 years.
