About this trial

This phase II trial compares the effect of folate receptor alpha dendritic cells (FRαDCs) to placebo in treating patients with stage III or IV ovarian, fallopian tube or primary peritoneal cancer. FRαDCs, a dendritic cell vaccine, is made from a person's white blood cells. The white blood cells are treated in the laboratory to make dendritic cells (a type of immune cell) mixed with folate receptor alpha (FRalpha), a protein found in high levels on ovarian tumor cells. FRαDCs work by boosting the immune system to recognize and destroy the tumor cells by targeting the FRalpha protein on the tumor cell. Placebo is an inactive substance that looks the same as, and is given the same way as, the active drug or treatment being tested. The effects of the active drug are compared to the effects of the placebo. Giving FRαDCs may work better in preventing or delaying recurrence compared to placebo in patients with stage III or IV ovarian, fallopian tube, or primary peritoneal cancer.

Eligibility criteria

Qualifiers

Age ≥ 18 years

Histological confirmation of Federation of Gynecology and Obstetrics (FIGO) stage III or stage IV epithelial ovarian, fallopian tube, or primary peritoneal cancer. NOTE: Histologic confirmation of the primary tumor is required. Eligible histotypes include high grade serous; endometrioid; and clear cell carcinoma, as these histotypes have high expression of FRα (Kalli, Oberg, Keeney, & et al., 2008). Mixed carcinomas, including carcinosarcomas, with ≥ 50% of the tumor comprised of high grade serous; and/or endometrioid; and/or clear cell carcinoma are eligible

Completion of cytoreductive surgery and one (and only one) course of platinum-based chemotherapy (5-9 cycles) ≥ 4 but ≤ 12 weeks prior to registration

NOTE: Cytoreductive surgery may have been prior to or after one or more cycles of chemotherapy and must include hysterectomy and bilateral salpingo-oophorectomy (if the uterus and/or ovaries were not previously removed)
