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 oxaliplatin and paclitaxel in treating patients who have metastatic or unresectable cancer.

Full description

OBJECTIVES:

• Determine the maximum tolerated dose of oxaliplatin and paclitaxel in patients with metastatic or unresectable cancer.
• Determine the qualitative and quantitative toxicities of this regimen in these patients.
• Determine the therapeutic response to this regimen in these patients.
• Determine the relationship between the pharmacokinetics of this regimen and toxicity and response in these patients.
• Determine the effects of oxaliplatin on peripheral blood cells and correlate this to pharmacokinetics, toxicity, and response in these patients.

OUTLINE: This is a dose escalation study.

Patients receive oxaliplatin IV over 2 hours followed by paclitaxel IV over 1 hour weekly for 4 weeks. Treatment repeats every 6 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of oxaliplatin and paclitaxel until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 of 6 patients experiences dose limiting toxicity.

PROJECTED ACCRUAL: Approximately 20 patients will be accrued for this study within 12-18 months.

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
