Phase II Study of Clinical Activity of Pegaspargase in Women With Relapsed or Refractory Epithelial Ovarian Cancer, Fallopian Tube Cancer, and/or Primary Peritoneal Cancer

Detailed Summary

Background: \- The best treatment for ovarian and related female reproductive tract cancers is not yet known for patients whose disease has not responded to or has recurred after standard treatment. The cancer treatment drug pegaspargase (ONCASPAR (Trademark)), which works differently from standard chemotherapy, has been approved to treat leukemia and has been given to a small number of patient with ovarian and other types of cancer. Because pegaspargase may reduce the development of cancer cells and blood vessel cells that contribute to cancer growth and ability to spread, treatment with pegaspargase could shrink ovarian cancer tumors and help ovarian cancer patients live longer and with fewer symptoms from their disease. Objectives: \- To evaluate the safety and effectiveness of pegaspargase in patients with recurrent or refractory ovarian cancer, fallopian tube cancer, and/or primary peritoneal cancer. Eligibility: \- Women at least 18 years of age who have been diagnosed with epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer that has not responded to at least one operation, chemotherapy, and/or radiotherapy. Design: * Before the start of the study, participants will be screened with a medical history, blood tests, imaging scans of the affected areas, tumor biopsies, and other tests as directed by the study doctors. * Participants will receive an infusion of pegaspargase on Day 1 and Day 15 of each 28-day cycle. * Participants will have dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) at the start of the study, before beginning pegaspargase, and again 6 weeks into the treatment. This test will determine if pegaspargase is affecting blood flow to the cancer site. * Participants will have a computed tomography scan or other imaging every other cycle (approximately every 8 weeks) to determine whether the therapy is affecting the cancer site. * The treatment will be repeated as long as the participant tolerates the medication and his or her cancer is either steady or improving.
