Maximum age: N/A
Minimum age: 18 Years

Inclusion Criteria:

1. Signed study Informed Consent Form

2. Karnofsky Performance Status (KPS) = 50

3. Age = 18 years

4. Patients with metastatic melanoma and multiple skin metastases with a documented
clinical progression despite the systemic treatments (chemotherapy, and/or Programmed
cell death 1 (PD1), cytotoxic T-lymphocyte antigen-4 (CTLA4) inhibitors or tyrosine
kinase inhibitors (TKIs), such as v-raf murine sarcoma viral oncogene homolog B1
(BRAF) or mitogen-activated extracellular signal-regulated kinase (MEK) inhibitors)

5. The size of the treated lesions should be = 5.5 cm in diameter and = 2.8 cm thick
(caliper-based measurement)

6. The treated lesions should be at least 5 cm apart and must not be located on the face.

7. Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy
test (urine or serum) during screening

8. WOCBP must use a contraceptive method

Exclusion Criteria:

2. Concomitant auto-immune disease with skin lesions

3. Concomitant use of radio-sensitizer drug

4. Women who are pregnant

5. Current, recent (within 10 days prior start of study treatment), or planned
participation in an experimental drug study. During the 4 weeks DLT period, the
patient will not be able to participate to any other clinical study.

6. Any serious underlying medical condition that could interfere with study treatment and
potential adverse events

7. Any mental or other impairment that may compromise compliance with the requirements of
the study
