A Study Of Crizotinib Versus Chemotherapy In Previously Untreated ALK Positive East Asian Non-Small Cell Lung Cancer Patients

Inclusion Criteria:

* Histologically or cytologically proven diagnosis of locally advanced not suitable for local treatment, recurrent and metastatic non-squamous cell carcinoma of the lung.
* Positive for translocation or inversion events involving the ALK gene locus.
* No prior systemic treatment for locally advanced or metastatic disease. Patients with brain metastases only if treated and neurologically stable for at least 2 weeks and are not taking any medications contraindicated in Exclusion Criteria
* Evidence of a personally signed and dated informed consent document and willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures including completion of patient reported outcome \[PRO\] measures.

Exclusion Criteria:

* Current treatment on another therapeutic clinical trial.
* Prior therapy directly targeting ALK.
* Any of the following within the 3 months prior to starting study treatment: myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, congestive heart failure, or cerebrovascular accident including transient ischemic attack. Appropriate treatment with anticoagulants is permitted.
* Ongoing cardiac dysrhythmias of NCI CTCAE Grade \>=2, uncontrolled atrial fibrillation of any grade, or QTc interval \>470 msec.
* Pregnancy or breastfeeding.
* Use of drugs or foods that are known potent CYP3A inducers/inhibitors Concurrent use of drugs that are CYP3A substrates with narrow therapeutic indices.
* Known HIV infection
* History of extensive disseminated/bilateral or known presence of Grade 3 or 4 interstitial fibrosis or interstitial lung disease, including a history of pneumonitis, hypersensitivity pneumonitis, interstitial pneumonia, interstitial lung disease, obliterative bronchiolitis, and pulmonary fibrosis, but not history of prior radiation pneumonitis.
* Other severe acute or chronic medical conditions (including severe gastrointestinal conditions such as diarrhea or ulcer) or psychiatric conditions, or end-stage renal disease on hemodialysis, or laboratory abnormalities that would impart, in the judgment of the investigator and/or sponsor, excess risk associated with study participation or study drug administration, and which would, therefore, make the patient inappropriate for entry into this study.
