MC1963 Folate Receptor Alpha Dendritic Cells (FRαDCs) or Placebo for Patients With Advanced Stage Ovarian Cancer: A Phase II Double-Blind Randomized Clinical Trial (FAROUT)
Mayo Clinic
Summary
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.
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 asses…
