  • Human leukocyte antigen (HLA)-A2 positive.
  • No evidence of radiographic disease
  • Predefined performance status
  • Female patients of childbearing potential must have a negative serum pregnancy test within 72 hours prior to randomization.

  • Patients with defined abnormal laboratory values:
  • Patients with presence of other concomitant active, invasive malignancies .
  • Patients with clinically significant active infection, cardiac disease, significant medical or psychiatric disease/condition that, in the opinion of the Investigator, would interfere with the interpretation of patient safety or study results or that would prohibit the understanding or rendering of informed consent
  • Patients with suspected autoimmune or active autoimmune disorder or known history of an autoimmune neurologic condition (e.g., Guillain-Barré syndrome)..
