Importance Cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4) blockade with
ipilimumab prolongs survival in patients with metastatic melanoma. CTLA-4 blockade and
granulocyte-macrophage colony-stimulating factor (GM-CSF)–secreting tumor vaccine
combinations demonstrate therapeutic synergy in preclinical models. A key unanswered
question is whether systemic GM-CSF (sargramostim) enhances CTLA-4 blockade.
