Liposomal Cisplatin in Treating Patients With Recurrent Ovarian Cancer

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of liposomal cisplatin in treating patients who have recurrent ovarian cancer.

OBJECTIVES: I. Determine the objective response rate in patients with recurrent platinum sensitive ovarian epithelial cancer treated with cisplatin liposomal (SPI-77). II. Determine the time to response, duration of response, time to progression, and survival in these patients treated with this regimen. III. Characterize the safety of this regimen in these patients.

OUTLINE: Patients receive cisplatin liposomal (SPI-77) IV over a minimum of 4 hours on day 1. Treatment repeats every 3 weeks for 6 courses in the absence of disease progression or unacceptable toxicity. Patients with clinical benefit after 6 courses may receive additional courses upon approval by the pharmaceutical sponsor. Patients are followed every 2 months for a minimum of 6 months and then periodically for survival.

PROJECTED ACCRUAL: A total of 26-63 patients will be accrued for this study.

Eligibility Criteria:
DISEASE CHARACTERISTICS: Histologically or cytologically proven recurrent ovarian epithelial cancer Metastatic disease allowed Must have received prior platinum containing chemotherapy Must be considered platinum sensitive and have had the following: Response to a prior platinum containing regimen No disease progression during prior platinum containing regimen Disease free interval of greater than 6 months following platinum containing regimen At least 1 bidimensionally measurable lesion No CNS metastases

PATIENT CHARACTERISTICS: Age: 18 and over Performance status: Karnofsky 70-100% Life expectancy: At least 3 months Hematopoietic: Absolute neutrophil count at least 1,500/mm3 Platelet count at least 100,000/mm3 Hemoglobin at least 9.0 g/dL Hepatic: Bilirubin no greater than 2.0 mg/dL AST no greater than 2 times upper limit of normal Albumin at least 2.5 g/dL Renal: Creatinine clearance at least 50 mL/min Cardiovascular: No uncontrolled heart disease or abnormal symptomatic cardiac function Other: Must have had a baseline hearing evaluation including an audiogram Not pregnant or nursing Negative pregnancy test Fertile patients must use effective contraception No acute infection requiring systemic therapy No signs of confusion or disorientation or prior major psychiatric illness that may preclude informed consent No grade 3 or 4 neurotoxicity from prior anticancer treatment or grade 2 or higher neuropathy from other causes No requirement for total parental nutrition with lipids No prior allergic reaction to cisplatin or platinum containing products
