- Histologically confirmed melanoma that is surgically incurable and either:
- Stage IIIc melanoma including locally relapsed, satellite, in-transit lesions or bulky draining lymph node metastasis.
- Stage IV melanoma (M1a, M1b, M1c) with accessible lesions for biopsy.
- At least 2 lesions amenable for outpatient biopsies
- No restriction based on prior treatments
- Disease progression after the last dose of prior therapy
- A minimum of one measurable lesion defined as:
- Meeting the criteria for measurable disease according to Response Evaluation Criteria in Solid Tumors
- Skin lesion(s) selected as non-completely biopsied target lesions that can be accurately measured and recorded by color photography with a ruler to document the size of the target lesion(s).
