This partially randomized phase I/IIb trial studies the side effects and best dose of IDO1
inhibitor INCB024360 in combination with DEC-205/NY-ESO-1 fusion protein CDX-1401 and poly
ICLC and to see how well they work in treating patients with ovarian, fallopian tube, or
primary peritoneal cancer who no longer have evidence of disease. Antigens (such as
cancer/testis antigen [NY-ESO-1] protein) are found on many cancer cells. Vaccines made from
NY-ESO-1 protein may cause the immune system to produce immune cells and antibodies that may
help locate the NY-ESO-1 and/or cancer/testis antigen 2 (LAGE-1) antigens on cancer cells. By
finding them, the immune system may then work to control or eliminate the remaining cancer
cells. INCB024360 is an inhibitor of an enzyme called indoleamine 2,3 dioxygenase (IDO). This
enzyme is produced by tumor cells to disable immune cells, and limit the efficacy of immune
attack. Giving DEC-205/NY-ESO-1 fusion protein CDX-1401 with poly ICLC and IDO1 inhibitor
INCB024360 may generate stronger and more long lasting anti-cancer immune responses in
patients with ovarian, fallopian tube, and primary peritoneal cancer in remission.
PRIMARY OBJECTIVES:
I. To determine the safety of fixed doses of DEC205mAb-NY-ESO-1 fusion protein
(DEC-205/NY-ESO-1 fusion protein CDX-1401) with adjuvant poly-ICLC given as a vaccine in
combination with INCB024360 (IDO1 inhibitor INCB024360). (Phase I) II. To evaluate toxicity
as defined by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events
(CTCAE) Version 4.0. (Phase I) III. To determine the progression free survival (PFS) (primary
endpoint) using standard immune-related response criteria (irRC) criteria. (Phase IIb)
SECONDARY OBJECTIVES:
I. To determine the effectiveness of INCB024360 on enhancing vaccine efficacy by assessing
cancer-testis antigen (NY-ESO-1) specific cellular and humoral immunity.
II. To determine the effectiveness of Sirolimus on enhancing vaccine efficacy by assessing
NY-ESO-1 specific cellular and humoral immunity (Exploratory Cohort ONLY) III. Peripheral
blood NY-ESO-1 specific cluster of differentiation (CD)8+ and CD4+ T cells.
IV. Peripheral blood NY-ESO-1 specific antibodies. V. Peripheral blood frequency of
CD4+CD25+forkhead box P3 (FOXP3)+ regulatory T cells.
VI. Pharmacokinetics of INCB02360 in relation to T cell frequency and function in correlation
with PFS.
OUTLINE:
PHASE I:
Patients receive DEC-205/NY-ESO-1 fusion protein CDX-1401 via intracutaneous injection on day
1, poly ICLC subcutaneously (SC) on days 1 and 2, and IDO1 inhibitor INCB024360 orally (PO)
twice daily (BID) on days 1-28. Treatment repeats every 28 days for up to 5 courses in the
absence of disease progression or unacceptable toxicity. Patients receive IDO1 inhibitor
INCB024360 for up to 7 courses.
PHASE IIb: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive DEC-205/NY-ESO-1 fusion protein CDX-1401 and poly ICLC as in Phase I.
ARM II: Patients receive DEC-205/NY-ESO-1 fusion protein CDX-1401, poly ICLC, and IDO1
inhibitor INCB024360 as in Phase I.
After completion of study treatment, patients are followed up for 30 days and then at 3, 6,
and 12 months.
