Outcome(s)

Primary Outcome

Overall Survival (OS) [ Time Frame: Up to approximately 48 months ]
OS is defined as the time from randomization to death from any cause.

Secondary Outcome

Progression free survival (PFS) [ Time Frame: Up to approximately 48 months ]
PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 based on BICR or death due to any cause, whichever occurs first.

Objective Response (OR) [ Time Frame: Up to approximately 48 months ]
The OR is defined as a confirmed complete response (CR) or partial response (PR) per RECIST 1.1 as assessed by BICR.

Duration of Response (DOR) [ Time Frame: Up to approximately 48 months ]
For participants who demonstrate confirmed CR or PR per RECIST 1.1 as assessed by BICR, duration of response is defined as the time from the first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first.

Change from Baseline in Global Health Status/Quality of Life (QOL) [European Organisation for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) 29 Items and 30] Score [ Time Frame: Baseline and up to approximately 24 months ]
Change from baseline in the score of EORTC QLQ-C30 Items 29 and 30 will be presented. The EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life of cancer patients. Participant responses to Items 29 and 30 ("How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?") are scored on a 7-point scale (1=Very Poor to 7=Excellent). A higher score indicates a better overall outcome.

Change From Baseline in Dyspnea (EORTC QLQ-C30 Item 8) Score [ Time Frame: Baseline and up to approximately 24 months ]
Change from baseline in the score of EORTC QLQ-C30 Item 8 will be presented. The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant response to the question "Were you short of breath?" is scored on a 4-point scale (1=Not at All to 4=Very Much). A higher score indicates a worse level of dyspnea.

Change From Baseline in Cough (EORTC QLQ-LC13 Item 31) Score [ Time Frame: Baseline and up to approximately 24 months ]
Change from baseline in the score of EORTC QLQ-C13 Item 31 will be presented. The EORTC QLQ-C13 is a lung cancer specific health-related quality-of life (QoL) questionnaire. Participant response to the question "Have you coughed?" is scored on a 4-point scale (1=Not at All to 4=Very Much). A higher score indicates more frequent coughing.

Change From Baseline in Chest Pain (EORTC QLQ-LC13 item 40) Score [ Time Frame: Baseline and up to approximately 24 months ]
The EORTC QLQ-LC13 is a lung cancer-specific supplemental questionnaire used in combination with the EORTC QLQ-C30. Participant responses to the question "Have you had pain in your chest?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in chest pain (EORTC QLQ-LC13 Item 40) score will be presented. A lower score indicates a better outcome.

Time to Deterioration (TTD) Based on Change From Baseline in Global Health Status (GHS)/ QOL Score (EORTC QLQ-C30 Item 29 and 30) [ Time Frame: Up to approximately 24 months ]
The TTD in GHS/QOL score (EORTC QLQ-C30 Items 29 and 30) will be presented. Participant responses to Items 29 and 30 ("How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?") are scored on a 7-point scale (1=Very Poor to 7=Excellent). A higher score indicates a better overall outcome. TTD as assessed based on a negative change (decrease in score) from Baseline in GHS/QOL score. A longer TTD indicates a better outcome.

Time to Deterioration (TTD) Based on Change From Baseline in Dyspnea Score (EORTC QLQ-C30 Item 8) [ Time Frame: Up to approximately 24 months ]
The TTD in Dyspnea score (EORTC QLQ-C30 Item 8) will be presented. Participant response to the question "Were you short of breath?" is scored on a 4-point scale (1=Not at All to 4=Very Much). A higher score indicates a worse level of dyspnea. TTD is assessed based on the time to a negative change (increase in score) from baseline. A longer TTD indicates a better outcome.

Time to Deterioration (TTD) Based on Change From Baseline in Cough Score (EORTC QLQ-LC13 Item 31). [ Time Frame: Up to approximately 24 months ]
The TTD in Cough score (EORTC QLQ-LC13 Item 31) will be presented. Participant response to the question "Have you coughed?" is scored on a 4-point scale (1=Not at All to 4=Very Much). A higher score indicates more frequent coughing. TTD is assessed based on the time to a negative change (increase in score) from baseline. A longer TTD indicates a better outcome.

Time to Deterioration (TTD) Based on Change From Baseline in Chest Pain Score (EORTC QLQ-LC13 Item 40) [ Time Frame: Up to approximately 24 months ]
The TTD in Chest Pain score (EORTC QLQ-LC13 Item 40) will be presented. Participant response to the question "Have you had pain in your chest?" is scored on a 4-point scale (1=Not at All to 4=Very Much). A higher score indicates a worse level of chest pain.
