Localized palliative radiation therapy to non-target lesions is permitted within the four weeks prior to randomization. * A predicted life expectancy of at least 6 months. * Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Exclusion Criteria: * Receipt of more than three (3) systemic treatment regimens for malignant melanoma (including IL-2). * A second malignancy within the last 5 years other than curatively treated carcinoma-in-situ or non-melanoma skin cancer. * Pregnant or lactating females.
