• Patients untreated or previously treated with one or more systemic regimen
• ECOG Performance status 0-2 (Appendix A)
• At least one untreated (not previously irradiated) target lesion that could be measured in one dimension, according to RECIST criteria
• A life expectancy of 12 weeks or more

• Adequate baseline bone marrow, hepatic and renal function, defined as follows:

  • Neutrophils > 1.5 x 109/L and platelets > 100 x 109/L
  • Bilirubin < 1.5 x ULN
  • AST and/or ALT < 2.5 x ULN in absence of liver metastasis or < 5 x ULN in presence of liver metastasis
  • Serum creatinine < 1.5 x ULN
  • Creatinine clearance (estimated according to Cockcroft-Gault formula) ≥ 50 ml/min

• Patients may have had prior treatment providing the following conditions are met before treatment start:

  • Surgery and radiation therapy: wash-out period of 14 days
  • Systemic therapy: wash-out period of 21 days
  • Patients must give written informed consent

Exclusion Criteria:

• Patients may not receive any other investigational agents while on study
• Patients with myocardial infarction within the last six (6) months, unstable angina, New York Heart Association (NYHA) grade II or greater congestive heart failure, or serious cardiac arrhythmia requiring medication
• LVEF < 55% (only for patients candidate for doxorubicin treatment)
• Uncontrolled hypertension
• Prolonged QTc interval (congenital or acquired) > 450 ms
• History or evidence upon physical examination of CNS disease unless adequately treated (e.g., primary brain tumor, any brain metastasis, seizure not controlled with standard medical therapy) or history of stroke
• Patients with active or uncontrolled systemic disease/infections or with serious illness or medical conditions, which is incompatible with the protocol
• Known hypersensitivity/allergic reaction or contraindications to human albumin preparations or to any of the excipients
• Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol
• Pregnancy or lactation. Patients - both males and females - with reproductive potential (i.e. menopausal for less than 1-year and not surgically sterilized) must practice effective contraceptive measures throughout the study. Women of child-bearing potential must provide a negative pregnancy test (serum or urine) within 14 days prior to registration
