• Presence of active nodal metastases (e.g., radiologic or clinical evidence of current nodal disease)
• Presence of more than 50 melanoma lesions
• Radiation therapy to any Study Lesion within 6 weeks of initial study treatment.

• Immunotherapy for cancer within 4 weeks of initial study treatment
• Local treatment (e.g., surgery, cryotherapy, laser ablation) to any Study Lesion within 4 weeks of initial study treatment
• Anti-tumor vaccine therapy within 6 weeks of initial study treatment.
• Investigational agents within 4 weeks of initial study treatment.

• Impaired wound healing or other extremity complications due to diabetes mellitus in subjects whose Study Lesions are located in an extremity
• Severe peripheral vascular disease in subjects whose Study Lesions are located in an extremity
• Significant concurrent or intercurrent illness, psychiatric disorders, or alcohol or chemical dependence that would, in the opinion of the Investigator, compromise the subject's safety or compliance or interfere with interpretation of study results.
