A Phase I/II Study to Determine the Maximum Tolerated Doses of Oral Topotecan, Carboplatin and Paclitaxel Administered Every 21 Days to Patients With Epithelial Ovarian Cancer Stages IIb, IIc, III and IV

OBJECTIVES:

• Determine the maximum tolerated dose, dose-limiting toxicity, and quantitative and qualitative toxic effects of oral topotecan combined with intravenous carboplatin and paclitaxel in patients with stage IIB, IIC, III, or IV ovarian epithelial cancer. (phase I closed to accrual 12/21/00)
• Evaluate the anti-tumor activity of this regimen in this patient population.

OUTLINE: This is a multicenter, dose-escalation study of topotecan.

Patients receive oral topotecan on days 1-5 and paclitaxel IV over 3 hours followed by carboplatin IV over 30 minutes on day 5. Courses repeat every 21 days for a maximum of 6 courses in the absence of disease progression or unacceptable toxicity.

• Phase I: Cohorts of 3-6 patients receive escalating doses of topotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 2 of 6 patients experience dose-limiting toxicity. (phase I closed to accrual 12/21/00)
• Phase II: An additional 50 patients receive up to 6 courses of treatment as in phase I at the MTD.
