3. Metastasis to the central nervous system or brain

4. Evidence of hearing impaired ≥ Grade 2 as assessed by pure tone audiometry or other neurotoxicity ≥ Grade 2

   * Patients with age-associated hearing loss at the high frequencies that, in the judgment of the investigator, would not interfere significantly with patient's safety or study assessments will be eligible to enroll.

As judged by the investigator, any evidence of significant laboratory findings or severe/uncontrolled clinical disorders (e.g. dementia, myocardial infarction within 6 months prior to enrollment, New York Heart Association (NYHA) Class III or IV heart failure, unstable angina, active cardiomyopathy, unstable arrhythmia, and other unstable or uncompensated respiratory, cardiac, hepatic, renal and/or infectious disease)
11. Patient with known hypersensitivity to Pt compounds
12. Known severe drug hypersensitivity
13. Treatment with a non-approved or investigational product within 30 days before Day 1 of study treatment

14. Alcoholic liver disease* or liver disease with obvious clinical symptom or sign

    * the investigator should judge from medical examination by interview and laboratory test including γ-GTP, AST and ALT

15.

21. Observation of "attenuated or reversed hepatic venous portal blood flow*" was confirmed by doppler ultrasonography or CT (recommend evaluation in arterial phase, portal-venous phase and equilibrium phase) of the liver * On doppler ultrasonography of right and left branch of portal vein, blood flow is measured as about 0 mL/min or between plus and minus, which indicate obvious blood flow obstruction
