About

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 combining flavopiridol and docetaxel in treating patients who have advanced solid tumors.

Full description

OBJECTIVES:

• Determine the dose-limiting toxic effects and maximum tolerated dose of flavopiridol and docetaxel in patients with advanced solid tumors.
• Determine the objective response rate and duration of response in patients treated with this regimen.
• Determine the pharmacokinetics of these drugs in this patient population.

OUTLINE: This is a dose-escalation study.

Patients receive docetaxel IV over 60 minutes on day 1 and flavopiridol IV continuously over 24 hours on day 2. Treatment repeats every 3 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of docetaxel and flavopiridol until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 6 patients experience dose-limiting toxicity.

PROJECTED ACCRUAL: A total of 18-24 patients will be accrued for this study within 9-11 months.

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
