Intervention code 
Comparator / control treatment
Primary outcome 
Number of Patients With Treatment-emergent Adverse Events - Toxicity was graded in accordance with the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.0. Treatment-emergent adverse events (TEAEs) were reported based on clinical laboratory tests, physical examinations, and vital signs from pre-treatment through the study period. Dose-limiting toxicity (DLT) was defined as any = Grade 3 hematologic or non-hematologic toxicity that was definitely, probably, or possibly related to the administration of the NY-ESO-1 vaccine or as any toxicity that was definitely, probably, or possibly related to ipilimumab and required permanent discontinuation of ipilimumab in accordance with local prescribing information. DLT assessments were based on the combination of all vaccine components, not on the components individually.
Continuously for up to 6 months
Secondary outcome 
Number of Patients With Immune-related Tumor Response at the Last Assessment - Immune-related tumor response was evaluated using the imaging techniques considered appropriate by the Investigators at Baseline, Week 13, and at the end of the study (Week 20 ± 1 week). Tumor response was designated according to the immune-related Response Criteria (irRC) (Wolchok et al. Clin Cancer Res 2009;15:7412-20) into the following categories: immune-related complete response (irCR) requires disappearance of all lesions in two consecutive observations not less than 4 weeks apart; immune-related partial response (irPR) requires = 50% decrease in tumor burden compared with baseline in two observations at least 4 weeks apart; immune-related stable disease (irSD) is assigned when neither a 50% decrease from baseline tumor burden nor a 25% increase in tumor burden from nadir can be established; immune-related progressive disease (irPD) requires a = 25% increase from nadir in tumor burden at any single time point in two consecutive observations at least 4 weeks apart.

Ethics application status
This was a Phase 1, open-label, non-randomized study of the combination of NY-ESO-1 plus
ipilimumab in patients with unresectable or metastatic melanoma for whom treatment with
ipilimumab was indicated. Patients must have had evidence of NY-ESO-1 or LAGE-1 tumor
positivity and radiologically measurable disease by the immune-related Response Criteria
(irRC). Primary study objectives were to determine the safety and tolerability of the
combination and to evaluate humoral and cellular immune response. Secondary objectives were
to evaluate tumor response and immunological changes in the tumor microenvironment.
