Phase II Study of First-Line Therapy of Ovarian Cancer With Sequential Regimens: Cisplatin-Prolonged Oral Topotecan (C-PORT) Followed by Paclitaxel/Carboplatin (PC)

OBJECTIVES:

• Determine the toxicity and tolerance of sequential therapy with prolonged
• Determine the response rate and time to progression in this patient
• Determine the relative pharmacokinetics of IV and prolonged oral administration of topotecan in the same patients and compare the pharmacodynamics of topo-1 inhibition when given by IV or oral route.

OUTLINE:

• Regimen A: Patients receive cisplatin IV over 60-90 minutes on day 1 of each course. Topotecan IV is administered continuously on days 1-14 of course 1. Oral topotecan is administered twice daily on days 1-14 for courses 2, 3, and 4. Treatment repeats every 28 days for 4 courses.
• Regimen B: After completion of regimen A, patients receive paclitaxel IV over 3 hours followed by carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for 4 courses.

PROJECTED ACCRUAL: A total of 30 patients (15 per arm) will be accrued for this study.
