• Known severe hypersensitivity to pre-medications required for treatment with cisplatin / vinorelbine doublet chemotherapy.
• Inability to comply with protocol or study procedures.
• A serious concomitant systemic disorder that, in the opinion of the investigator, would compromise the patient's ability to complete the study.
• A serious cardiac condition, such as myocardial infarction within 6 months, angina, or heart disease.
• Interstitial pneumonia.

Cured basal cell carcinoma of the skin and cured in situ carcinoma of the uterine cervix are permitted.
• Any unstable systemic disease (including active infection, uncontrolled hypertension, unstable angina, congestive heart failure, myocardial infarction within the previous year, serious cardiac arrhythmia requiring medication, hepatic, renal, or metabolic disease).
• Eye inflammation or eye infection not fully treated or conditions predisposing the subject to this.
• Evidence of any other disease, neurological or metabolic dysfunction, physical examination or laboratory finding giving reasonable suspicion of a disease or condition that contraindicated the use of an investigational drug or puts the subject at high risk for treatment-related complications.
