Study Description

Brief Summary: This was a Phase 1, open-label study of repeated vaccination with NY-ESO-1 overlapping peptides (OLP4) with or without the immunoadjuvants Montanide and polyinosinic-polycytidylic acid - poly-L-lysine carboxymethylcellulose (poly-ICLC) administered every 3 weeks for a total of 5 vaccinations in subjects with epithelial ovarian, fallopian tube, or primary peritoneal cancer in second or third clinical remission. Study objectives included determination of the safety and immunogenicity following vaccination.

Detailed Description: Subjects received NY-ESO-1 OLP4 by subcutaneous injection once every 3 weeks (Weeks 1, 4, 7, 10, and 13) for a total of 5 vaccinations. Subjects were assigned sequentially to 1 of 3 dosing cohorts: Cohort 1: received NY-ESO-1 OLP4 alone; Cohort 2: received NY-ESO-1 OLP4 in combination with Montanide; Cohort 3: received NY-ESO-1 OLP4 in combination with Montanide and Poly-ICLC. Enrollment into each subsequent dosing cohort was dependent on a dose-limiting toxicity (DLT) rate of \<33% in the preceding cohort. No dose escalation was planned. Subjects were observed by study staff for up to 30 minutes following each vaccination. Immunologic assessments were performed prior to the first vaccination and 3 weeks after each vaccination. Toxicity assessments were performed with each vaccination and 3 weeks after the completion of therapy (ie, the final study visit was Week 16). Immunologic assessments included measurement of the anti-NY-ESO-1 antibody by enzyme-linked immunsorbent assay (ELISA), detection of CD-4 and CD-8 cellular responses by tetramer and enzyme-linked immunosorbent spot assay (ELISPOT), and delayed-type hypersensitivity (DTH).
