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 3-AP, cisplatin, and paclitaxel in treating patients who have advanced or metastatic cancer.

Full description

OBJECTIVES:

• Determine the safety and tolerability of 3-AP, cisplatin, and paclitaxel in patients with advanced or metastatic cancer.
• Determine the toxic effects of this regimen in these patients.
• Determine the maximum tolerated dose and recommended phase II dose of this regimen in these patients.
• Determine the pharmacokinetic parameters of this regimen in these patients.
• Determine the tumor response in patients treated with this regimen.

OUTLINE: This is a dose-escalation study.

Patients receive 3-AP IV continuously over 96 hours on days 1-4 and paclitaxel IV over 3 hours followed by cisplatin IV over 1 hour on day 3. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients achieving complete response (CR) receive 1 additional course of therapy after documented CR. Patients with partial response or stable disease may receive therapy for up to 6 months.

Cohorts of 1-6 patients receive escalating doses of 3-AP, paclitaxel, and cisplatin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

PROJECTED ACCRUAL: Approximately 25-30 patients will be accrued for this study.
