Combination Chemotherapy in Treating Patients With Advanced Solid Tumors

National Cancer Institute (NCI)13 enrolled

Overview

Phase I trial to study the effectiveness of combining alvocidib, irinotecan hydrochloride, and cisplatin in treating patients who have advanced solid tumors. 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.

OBJECTIVES: I. Determine the maximum tolerated dose of flavopiridol (alvocidib), irinotecan (irinotecan hydrochloride), and cisplatin in patients with advanced solid tumors. II. Determine the clinical pharmacokinetics of this regimen in these patients. III. Determine, preliminarily, the therapeutic activity of this regimen in these patients. OUTLINE: This is a dose-escalation study. Patients are stratified according to the number of prior treatment regimens (0 or 1 vs more than 1). Patients receive irinotecan hydrochloride intravenously (IV) over 30 minutes followed immediately by cisplatin IV over 30 minutes followed 7 hours later by alvocidib IV over 1-4.5 hours weekly for 2 weeks. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of cisplatin, alvocidib, and irinotecan hydrochloride until the maximum tolerated dose (MTD) of each is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, 12 additional patients are treated at the recommended phase II dose.

Outcomes

Primary Outcomes

MTD alvocidib when administered in conjunction with irinotecan hydrochloride and cisplatin

Defined as the dose one level below the dose at which two or more of the patients in the initial cohort experience dose limiting toxicity (DLT) during the first treatment course. DLT is defined as the occurrence of Grade 4 hematologic toxicity, Grade 3 or 4 non-hematologic toxicity including diarrhea despite antidiarrheal prophylaxis, or any delay in treatment resulting in less than 2 treatments in 3 weeks.

Time frame: Course 1

Secondary Outcomes

Clinical pharmacokinetics of the regimen

Time frame: Week 1 of courses 1 and 2

Therapeutic activity of alvocidib in combination with irinotecan hydrochloride in patients with advanced solid tumors

Evaluated using Response Evaluation Criteria In Solid Tumors (RECIST).

Time frame: After 2 courses of treatment

Safety and tolerability

Evaluated using the National Cancer Institute (NCI) Common Toxicity Criteria. Tabulated individually, and summarized by body system, according to dosage of study medication.

Time frame: Weekly
