This phase I trial studies the side effects and best dose of indoleamine-2,3-dioxygenase (IDO1) inhibitor INCB024360 when given together with donor natural killer (NK) cells and aldesleukin after preparative chemotherapy in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back despite previous treatment. Chemotherapy is given before treatment to prepare the body for the infusion by lowering the immune system so that it does not see the donor NK cells as foreign invaders and to make room in the bone marrow for the donor NK cells to expand. NK cells are a type of white blood cell that can kill viruses and tumor cells. Aldesleukin is given to stimulate the NK cells to expand. Giving donor NK cells and aldesleukin directly into the abdominal space may be a way to get higher doses of treatment directly to the cancer cells with less severe side effects than intravenous administration. IDO1 blocks the immune system from being able to attack the cancer cells. INCB024360 is thought to inhibit (block) IDO1, which in turn should increase the body’s immune response and effectiveness of the NK cells.

PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD) of INCB024360 (IDO1 inhibitor INCB024360) when administered with intraperitoneal haploidentical donor NK cells/interleukin-2 (IL-2) (aldesleukin) after a nonmyeloablative cyclophosphamide/fludarabine (fludarabine phosphate) (Cy/Flu) preparative regimen in patients with recurrent ovarian, fallopian tube, and primary peritoneal cancer.
SECONDARY OBJECTIVES:
I. To characterize the frequency and severity of toxicities of oral INCB024036 when administered twice daily for 3 months after intraperitoneal delivery of haploidentical donor NK cells and IL-2.
II. To obtain preliminary efficacy information of this treatment in recurrent ovarian, fallopian tube, primary peritoneal cancer.
III. To estimate time to progression (TTP), progression-free survival (PFS) and overall survival (OS).
TERTIARY OBJECTIVES:
I. To determine the proportion of patients with NK cell expansion at day 14.
II. To assess whether or not NK cells are present in the blood and peritoneum.
III. To quantify the number of NK cells in the blood and peritoneum.
IV. To evaluate peripheral blood immune cell IDO inhibition, as well as markers of inflammation and immune modulation and to correlate these parameters with response and/or survival.
V. To evaluate IDO expression and characterize immune response in ascites, intraperitoneal washings, and/or tumor tissue and how these parameters correlate with response and/or survival.
VI. To evaluate the suppression of the rise in the kynurenine (KYN)/tryptophan (TRP) ratio after adoptive transfer and its role as a biomarker.
OUTLINE: This is a dose-escalation study of IDO1 inhibitor INCB024360.
PREPARATIVE REGIMEN: Patients receive fludarabine phosphate intravenously (IV) over 1 hour on days -6 to -2, cyclophosphamide IV over 2 hours on days -5 and -4, and IDO1 inhibitor INCB024360 orally (PO) twice daily (BID) for 3 months beginning on day -2.
ALLOGENEIC NK CELL INFUSION AND ALDESLEUKIN: Patients receive NK cells intraperitoneally (IP) on day 0 followed by aldesleukin IP three times per week for 6 doses beginning on day 0.
Patients achieving initial response or clinical benefit who progress after 6 months may repeat treatment.
After completion of study treatment, patients are followed up at days 90, 180, and 365.
