Inclusion Criteria:

• Histological or cytological confirmation of malignant melanoma that is metastatic or unresectable
• Measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension as 10mm or greater with spiral CT scan
• Patients may have received up to 4 prior treatments for their disease including immunotherapies such as high-dose interleukin 2 and antibodies directed against the human cytotoxic T-lymphocyte antigen 4
• 18 years of age or older
• Life expectancy of greater than three months
• ECOG Performance status of 0 or 1
• Adequate organ and marrow function as outlined in the protocol
• Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment
• INT < 1.5 or a PT/PTT within normal limits. Patients receiving anti-coagulation treatment wih an agent such as warfarin or heparin may be allowed to participate. For patients on warfarin, the INR should be measured prior to initiation of sorafenib and monitored at least weekly, or as defined by the local standard of care, until INR is stable
• Women of child-bearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation.

• Participants receiving any medications or substances that are inducers of CYP3A4
• Known cardiac disease including congestive heart failure > class II NHYA, unstable angina or new onset angina, myocardial infarction within the past 6 months, or electrocardiographic evidence of acute ischemic or active conduction system abnormalities. Prior to study entry, any ECG abnormality at screening has to be documented by the investigator as not medically relevant
