Documented measurable disease as defined by RECIST v1.1 7. Adequate hematologic parameters, and hepatic and renal functions defined as 1. absolute neutrophil count = 1,000/µL 2. platelets = 75,000/µL 3. total bilirubin = 2.5X ULN (= 5X ULN if attributable to liver metastases) 4. AST/ALT = 2.5X ULN (= 5X ULN if attributable to liver metastases) 5. serum creatinine = 2 mg/dL or creatinine clearance = 30 mL/min (by calculated or 24-hour urine collection) 8. Normal ECG or ECG without any clinical significant findings 9. Able to understand and sign an informed consent (or have a legal representative who is able to do so) Exclusion Criteria: Patients will be excluded from the study if they meet any of the following criteria: 1.
