Summary:

      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.
