Tirapazamine, Carboplatin, and Paclitaxel in Treating Patients With Advanced Malignant Solid Tumors
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 tirapazamine, carboplatin, and paclitaxel in treating patients who have advanced malignant solid tumors.
Unspecified Adult Solid Tumor, Protocol Specific
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Phase I Dose Escalation Study of Tirapazamine (NSC 130181) in Combination With Carboplatin and Paclitaxel in Advanced Malignant Solid Tumors|
|Study Start Date:||March 2000|
|Primary Completion Date:||July 2012 (Final data collection date for primary outcome measure)|
- Determine the maximum tolerated dose of tirapazamine in combination with carboplatin and paclitaxel in patients with advanced solid tumors who have or have not received prior chemotherapy.
- Assess the toxicity and preliminary efficacy of this regimen in these patients.
- Determine the pharmacokinetic profile of this regimen in these patients.
- Investigate potential predictors of response by studying patient tissue specimens after receiving this regimen.
OUTLINE: This is a dose-escalation study of tirapazamine. Patients are stratified according to prior chemotherapy status (previously untreated vs previously treated).
Patients receive tirapazamine IV over 2 hours, paclitaxel IV over 3 hours, and carboplatin IV over 30 minutes. Treatment continues every 21 days for a maximum of 8 courses in the absence of unacceptable toxicity or disease progression. Some patients may continue therapy in the absence of unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of tirapazamine 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. An additional 12 patients in the previously untreated stratum are treated at the MTD.
Patients are followed indefinitely.
PROJECTED ACCRUAL: A total of 36-68 patients (18-34 per stratum) will be accrued for this study within 12-18 months.
