About
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.
Full description
PRIMARY OBJECTIVE:
I. Compare recurrence-free survival (RFS) in advanced ovarian carcinoma (OC) patients vaccinated with multi-epitope folate receptor alpha-loaded dendritic cell vaccine (FRαDCs) (active vaccine) versus placebo.
SECONDARY OBJECTIVES:
I. Compare overall survival (OS) in advanced OC patients vaccinated with FRαDCs versus placebo.
II. Compare the adverse event (AE) profile of FRαDCs with that of placebo.
CORRELATIVE RESEARCH OBJECTIVES:
I. Assess association of pre-existing immune microenvironment with RFS. II. Characterize the T cell and antibody responses to FRα and assess the association between the emergence of immunity and RFS.
III. Assess for epitope spreading and evaluate the association between epitope spreading and RFS.
IV. Compare archival tissue from surgery with post-recurrence biopsy tissue in those patients who develop recurrence to assess for common immune evasion mechanisms.
V. Evaluate differences in ribonucleic acid (RNA) expression of FRαDCs and its association with RFS.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients may receive tetanus and diphtheria vaccine (Td) or tetanus-diphtheria-accellular pertussis vaccine (Tdap) intramuscularly (IM) prior to undergoing leukapheresis. Patients receive FRalphaDCs intradermally (ID) on day 1 of each cycle. Cycles repeat every 21 days for cycles 1-5 and then repeat every 91 days for cycles 6-12 in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo biopsy prior to apheresis and optionally at end of treatment, and blood sample collection, computed tomography (CT) and/or magnetic resonance imaging (MRI) throughout the study.
ARM II: Patients may receive Td or Tdap IM prior to undergoing leukapheresis. Patients receive placebo ID on day 1 of each cycle. Cycles repeat every 21 days for cycles 1-5 and then repeat every 91 days for cycles 6-12 in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo biopsy prior to apheresis and optionally at end of treatment, and blood sample collection, CT and/or MRI throughout the study.
After completion of study treatment, patients are followed up every 3 months for up to month 36 then every 3 months until progression followed by every 6 months for up to year 8.

Inclusion criteria
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
Germline and somatic genetic testing have been completed
Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1, or 2
Expected survival ≥ 6 months
Hemoglobin ≥ 8.5 g/dL (≤ 15 days prior to registration)
Absolute neutrophil count (ANC) ≥ 1000/mm^3 (≤ 15 days prior to registration)
Platelet count ≥ 75,000/mm^3 (≤ 15 days prior to registration)
Lymphocytes ≥ 0.3 x 10^9/L (≤ 15 days prior to registration)
Monocytes ≥ 0.25 x 10^9/L (≤ 15 days prior to registration)
Total bilirubin ≤ upper limit of normal (ULN), unless patient has a documented history of Gilbert's disease, then direct bilirubin ≤ ULN (≤ 15 days prior to registration)
Aspartate transaminase (AST) ≤ 3 x ULN (≤ 15 days prior to registration)
Creatinine clearance ≥ 30 mL/min per Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation (≤ 15 days prior to registration)
Provide written informed consent
Willing to provide mandatory blood specimens for correlative research
Willing to provide archival tissue specimen for correlative research
Willing to return a participating institution for follow-up (during the active monitoring phase of the study)
Willing to undergo a tetanus vaccination (if not performed ≤ 365 days prior to registration)
Willing to have a central access line placed, if needed (as determined during venous access assessment)
Exclusion criteria
Any of the following because this study involves an investigational agent, the genotoxic, mutagenic, and teratogenic effects of which on the developing fetus and newborn are unknown
Evidence of disease at the time of registration, including clinical concern for disease recurrence based on each of the following:
Germline or somatic BRCA1 or BRCA2 mutation, as determined by Clinical Laboratory Improvement Act (CLIA)-approved tests
Prior radiation therapy for this cancer
Treatment with chemotherapy, angiogenesis inhibitor therapy, poly (ADP-ribose) polymerase (PARP) inhibitor therapy, radiation therapy, or other immunotherapy ≤ 4 weeks prior to registration
Receiving any other standard therapy (angiogenesis inhibitor, PARP inhibitor) or investigational agent, which would be considered as a treatment for the primary neoplasm. These agents have been shown to be active in later line therapy and can be used at that time for patients who relapse after treatment on this trial
Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
Immunocompromised patients and patients known to be HIV positive and currently receiving antiretroviral therapy
Uncontrolled intercurrent illness including, but not limited to:
Other active malignancy ≤ 3 years prior to registration
History of myocardial infarction ≤ 6 months prior to registration, or congestive heart failure requiring use of ongoing maintenance therapy for life-threatening ventricular arrhythmias
Treatment with systemic immunosuppressive medication (including, but not limited to, prednisone, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor [TNF]-alpha agents) ≤ 2 weeks prior to registration, or anticipation of need for systemic immunosuppressive medication during the course of the study
