• • An adequate liver function: ASAT (SGOT) and ALAT (SGPT) ≤ 2.5 x ULN (≤ 5 x ULN if there are liver metastases). Total bilirubin \< 1.5 x ULN. Alkaline phosphatase ≤ 2.5 x ULN ( ≤ 5 x ULN in the case of liver metastases or ≤ 10 x ULN in the case of bone metastases)
• Exclusion Criteria:
• • To have received prior systemic treatment for the metastatic disease
• • Diagnosis or suspicion of brain or leptomeningeal metastases

• • Serious active infection, including active tuberculosis and HIV diagnosis.
• • Chronic immunological or hormonal treatment, except for hormone replacement treatment at physiological doses.
• • Known drug or alcohol abuse.
• • Legal incapacity or limited legal capacity.
