OPT-821 With or Without Vaccine Therapy in Treating Patients With Ovarian Epithelial Cancer, Fallopian Tube Cancer, or Peritoneal Cancer in Second or Third Complete Remission

This randomized phase II trial studies OPT-821 and vaccine therapy to see how well they work compared with OPT-821 alone in treating patients with ovarian epithelial cancer, fallopian tube cancer, or peritoneal cancer that has decreased or disappeared, but the cancer may still be in the body. Biological therapies, such as OPT-821, may stimulate the immune system in different ways and stop tumor cells from growing. Vaccines may help the body build an effective immune response to kill tumor cells. It is not yet known whether OPT-821 is more effective with or without vaccine therapy in treating patients with ovarian epithelial cancer, fallopian tube cancer, or peritoneal cancer.
