Phase 2: Change From Baseline in European Organization for the Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) Global Health Status Scale Score at End of Treatment (EOT)	EORTC QLQ-C30 is a 30-question tool used to assess the overall quality of life (QoL) in cancer participants. It consisted of 15 domains: 1 global health status (GHS) scale, 5 functional scales (Physical, role, cognitive, emotional, social), and 9 symptom scales/items (Fatigue, nausea and vomiting, pain, dyspnoea, sleep disturbance, appetite loss, constipation, diarrhea, financial impact. The EORTC QLQ-C30 GHS/QoL score ranges from 0 to 100; High score indicates better GHS/QoL. Score 0 represents: very poor physical condition and QoL. Score 100 represents: excellent overall physical condition and QoL.	Baseline and EOT (up to 110 weeks)
Phase 2: Time-to-Symptom Progression (TTSP)	TTSP was measured from randomization to symptomatic progression by lung cancer symptom scale (LCSS) used to measure symptom changes relevant to quality of life (QoL).It consisted of 9 items focused on cancer symptoms (loss of appetite, fatigue, cough, shortness of breath, blood in sputum, pain, symptoms of cancer, illness affecting normal activity, QoL).For each symptom score distance from left boundary to point where participant has marked line was measured in millimeters (mm).Total scale length was 100 mm. Symptomatic progression was defined as increase/worsening of average symptomatic burden index (ASBI) (mean of 6 major lung cancer specific symptom scores);Worsening defined as 10% increase of scale breadth from baseline. Score 0 indicate no/minimum symptoms;100 indicates maximum level of symptoms.	Up to 328 weeks
