3-AP and Cisplatin in Treating Patients With Recurrent or Persistent Platinum-Resistant Ovarian Epithelial or Primary Peritoneal Cancer

PRIMARY OBJECTIVES:

I. Determine the antitumor activity of 3-AP and cisplatin in patients with recurrent or persistent platinum-resistant ovarian epithelial or primary peritoneal cancer.

II. Determine the toxicity of this regimen in these patients.

SECONDARY OBJECTIVES:

I. Determine the duration of progression-free survival and overall survival in patients treated with this regimen.

II. Determine the effects of prognostic variables, including initial performance status, age, and mucinous (or clear cell) histology, in these patients.

OUTLINE: This is a non-randomized study.

Patients receive 3-AP IV over 2 hours on days 1-4 and cisplatin IV over 1 hour on days 2 and 3. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients are followed for 5 years.

PROJECTED ACCRUAL: A total of 23-48 patients will be accrued for this study within 13 months.
