Résumé
Date de début de l'étude : 1 mai 2000
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: * Determine the maximum tolerated dose (MTD) of capecitabine when combined with paclitaxel in patients with metastatic adenocarcinoma of the breast. * Determine the clinical efficacy of the dose immediately preceding the MTD identified in phase I, in terms of response rate, time to treatment failure, time to disease progression, and overall survival, in these patients. * Determine the toxicity of this regimen in these patients. * Determine a well-tolerated drug combination for these patients. OUTLINE: This is a dose-escalation, multicenter study of capecitabine. Patients receive oral capecitabine twice daily on days 1-14 and paclitaxel IV over 1 hour on days 1, 8, and 15. Treatment repeats every 21 days for a maximum of 6 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of capecitabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 2 or more of 6 patients experience dose-limiting toxicity. Once the MTD is determined, additional patients are treated at the dose level immediately preceding the MTD. Patients are followed every 3 months. PROJECTED ACCRUAL: A total of 3-24 patients will be accrued for phase I and 15-46 patients will be accrued for phase II of this study.
