Vaccine Therapy and OPT-821 or OPT-821 Alone in Treating Patients With Ovarian Epithelial Cancer, Fallopian Tube Cancer, or Primary Peritoneal Cancer in Complete Remission

RATIONALE: Vaccines made from tumor antigens may help the body build an effective immune response to kill tumor cells. Biological therapies, such as OPT-821, may stimulate the immune system in different ways and stop tumor cells from growing. Giving vaccine therapy together with OPT-821 may kill more tumor cells. It is not yet known whether giving vaccine therapy together with OPT-821 is more effective than OPT-821 alone in treating ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer. PURPOSE: This randomized phase III trial is studying vaccine therapy and OPT-821 to see how well they work compared with OPT-821 alone in treating patients with ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer in complete remission.
