DEC-205/NY-ESO-1 Fusion Protein CDX-1401, Poly ICLC, and IDO1 Inhibitor INCB024360 in Treating Patients With Ovarian, Fallopian Tube, or Primary Peritoneal Cancer in Remission

A Phase I/IIb Study of DEC205mAb-NY-ESO-1 Fusion Protein (CDX-1401) Given With Adjuvant Poly-ICLC in Combination With INCB024360 for Patients in Remission With Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Carcinoma Whose Tumors Express NY-ESO-1 or LAGE-1 Antigen

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.

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.
