Exclusion Criteria:

Cancer-Specific Exclusion Criteria

• Known active or untreated central nervous system (CNS) metastases.Patients with a history of treated asymptomatic CNS metastases are eligible, if they meet all of the following criteria: No metastases to brain stem, midbrain, pons, medulla, cerebellum, or within 10 mm of the optic apparatus. Radiographic demonstration of improvement upon the completion of CNS directed therapy and no evidence of interim progression between the completion of CNS-directed therapy and the screening radiographic study
• History of intracranial hemorrhage
• Ongoing requirement for dexamethasone for CNS disease
• Stereotactic radiation or whole-brain radiation within 28 days prior to Cycle 1,Day 1
• Screening CNS imaging ≥ 4 weeks since completion of radiotherapy and ≥ 2 weeks since discontinuation of corticosteroids
• Spinal cord compression not definitively treated with surgery and/or radiation or previously diagnosed and treated spinal cord compression that has not been clinically stable for ≥ 2 weeks prior to randomization
• Leptomeningeal disease
• Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures
• Uncontrolled tumor-related pain: patients requiring pain medication must be on a stable regimen at study entry. Symptomatic lesions amenable to palliative radiotherapy should be treated prior to enrolment. Asymptomatic metastatic lesions whose further growth would likely cause functional deficits or intractable pain should be considered for loco-regional therapy prior to enrolment.
• Hypercalcemia (Ca > 1.5 mmol/L ionized calcium or Ca > 12 mg/dL or corrected serum calcium > ULN) or symptomatic hypercalcemia requiring continuous bisphosphonate therapy or denosumab. Patients who are receiving bisphosphonate therapy or denosumab specifically to prevent skeletal events and without a history of clinically significant hypercalcemia are eligible.
• Malignancies other than NSCLC within 5 years prior to randomization, with the exception of those with a negligible risk of metastasis or death and treated with curative outcome

General Exclusion Criteria

• Significant uncontrolled concomitant disease that could affect compliance with the protocol or interpretation of results, including significant liver disease
• Significant cardiovascular disease, such as myocardial infarction within 3 months prior to randomization, unstable arrhythmias, or unstable angina.
• Known left ventricular ejection fraction (LVEF) \< 40%. Patients with known coronary artery disease, congestive heart failure not meeting the above criteria, or LVEF \< 50% must be on a stable medical regimen.
