Experimental: rV- and rF-NY-ESO-1
Patients received a single intradermal injection of rV-NY-ESO-1 (3.1 × 10^7 PFU) on Day 1, followed by subcutaneous injections of rF-NY-ESO-1 (7.41 × 10^7 PFU) on Days 29, 57, 85, 113, 141, and 169 or until observation of treatment-related ≥ grade 3 toxicity or disease progression.
Biological: rV-NY-ESO-1 vaccine
Patients received a single intradermal injection of rV-NY-ESO-1 (3.1 × 10^7 PFU) on Day 1.
Biological: rF-NY-ESO-1 vaccine
Patients received subcutaneous injections of rF-NY-ESO-1 (7.41 × 10^7 PFU) on Days 29, 57, 85, 113, 141, and 169.
- Percentage of Patients in Remission at 1 Year [ Time Frame: 12 months ]Time to failure (TTF) was evaluated as the crude proportion of patients in remission at 1 year, calculated as: 100 x (number of patients in remission at 1 year)/(number of patients with known status at 1 year). The Kaplan-Meier cumulative estimate of the proportion of patients in remission at 1 year was also calculated.
- Mean Time to Failure Among Patients Who Progressed On Study [ Time Frame: Up to 20 months ]TTF was calculated as the number of days from the first dose until the patient discontinued due to progressive disease. Patients who completed the study or discontinued for other reasons were considered censored at the day of their last study visit, including the follow-up visits after Day 197. Progression was defined using the Response Evaluation Criteria In Solid Tumors (RECIST [version 1.0]) as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions
- Number of Patients With Best Overall Tumor Response [ Time Frame: Up to 20 months ]Tumor responses were evaluated using computed tomography and were categorized according to RECIST (version 1.0) at Screening, on Days 85 and 197 and every 2 months thereafter for at least 12 months. Per RECIST, target lesions are categorized as follows: Complete Response (CR): Disappearance of all target lesions (no evaluable disease); Partial Response (PR): ≥ 30% decrease in the sum of the longest diameter of target lesions; Progressive Disease (PD): ≥ 20% increase in the sum of the longest diameter of target lesions; Stable Disease (SD): small changes that do not meet above criteria.
- Mean Absolute Cancer Antigen-125 Values Over Time on Study [ Time Frame: Up to 20 months ]Blood samples were collected to measure serum levels of tumor marker cancer antigen (CA)-125 at Screening and on Days 1, 29, 57, 85, 113, 141, 169, and 197 and every 2 months for at least 12 months following Day 197.
- Number of Patients With NY-ESO-1 and LAGE-1-specific Immunity [ Time Frame: Up to 20 months ]Specific antibody response to the NY-ESO-1 and LAGE-1 antigen was measured by enzyme-linked immunosorbent assay (ELISA) at Screening, Days 29, 57, 85, 113, 141, 169, 197, Month 6, and Month 12.
- Number of Patients With Release of Interferon-Gamma by T Cells in Response to Cancer Antigens [ Time Frame: Up to 20 months ]Intracellular cytokine staining assays were performed at Screening, Days 85 and 197, Month 6, and Month 12 to evaluate the release of interferon-gamma by CD4 and CD8 T cells following study injections.
- Number of Patients With Detectable T-cell Responses Following Vaccination [ Time Frame: Up to 20 months ]NY-ESO-1-specific CD8+ T cells (human leukocyte antigen [HLA]-A2 patients only) and NY-ESO-1-specific CD4+ T cells (HLA-DP4 patients only) were measured by interferon-gamma enzyme-linked immunosorbent spot (ELISPOT) assay. The response to the ELISPOT assay was considered to be positive if the number of spots in the peptide-exposed well was 2-fold or more higher than the number of spots in the unstimulated well, and if there was a minimum of 10 (after subtraction of background spots) peptide-specific spots/25,000 T-cells, or less if T-cell clones were used.
- Number of Patients With Delayed-Type Hypersensitivity Reactions Following Vaccination [ Time Frame: Up to 6 months ]NY-ESO-1 antigen-specific delayed-type hypersensitivity (DTH) was measured by skin test at Screening and on Days 113 and 197. All patients were tested for the NY-ESO-1 protein, with additional DTH testing as follows: patients who were HLA-A2+ had NY-ESO-1b testing, patients who were HLA-DP4+ had NY-ESO-DP4 testing, and patients who were both HLA-A2+ and HLA-DP4+ had NY-ESO-1b and NY-ESO-DP4 testing.
- Number of Patients With Treatment-emergent Adverse Events [ Time Frame: Continuously for up to 20 months ]Toxicity was graded in accordance with the National Cancer Institute (NCI) Common Toxicity Criteria (CTC), version 3.0. Treatment-emergent adverse events (TEAEs) were reported based on clinical laboratory tests, physical examinations, and vital signs from pre-treatment through the study period.
