Cytokine-induced Killer Study for Patients With Stage II Melanoma

For investigators' current experimental clinical trial, patients are given 4 injections of ipilimumab, given 3 weeks apart x 4 injections with or without cytokine-induced killer therapy. Investigators propose to test this dual therapy in patients with melanoma who have known stage I, metastatic melanoma. Investigators hypothesize that this form of combinatorial immunotherapy will result in tumor stabilization or shrinkage, significant prolongation of progression-free, disease-free or overall survival compared to the use of ipilimumab alone
