A Phase II Trial of 72-Hour Continuous IV Infusion of 9-Aminocamptothecin With G-CSF Support in Patients With Advanced Ovarian Cancer Previously Treated With Paclitaxel and Cisplatin

This is a Phase II study of 9-aminocamptothecin (9-AC), administered as an intravenous continuous infusion over 72 hours with G-CSF support for patients with advanced refractory ovarian cancer. The objectives of the present study are to determine the response rate to 9-AC in patients with advanced ovarian cancer who have recurrent disease after paclitaxel- and cisplatin-based chemotherapy regimens.

DISEASE CHARACTERISTICS:

Histologically proven, advanced epithelial ovarian cancer.

Histologic confirmation by Pathology Department, NIH, required.

Recurrent disease after paclitaxel and either cisplatin or carboplatin. Combination platinum/paclitaxel acceptable.

Bidimensionally measurable disease on physical exam, radiographs, or peritoneoscopy. Repeat peritoneoscopy after 8 courses of therapy required if documentation of disease was solely by peritoneoscopy.

Laparotomy not required.

No CNS metastasis.

No borderline or mixed histology.

PRIOR/CONCURRENT THERAPY:

See Disease Characteristics.

More than 4 weeks since any prior therapy and recovered.

No prior camptothecin analogue-based chemotherapy.

No prior radiotherapy except intraperitoneal 32-P.
