- Progression-Free Survival (Site Read, Investigator Assessment) [ Time Frame: Radiologic evaluations were carried out every 6 weeks from randomization until documented progression, withdrawal of consent, loss to follow up, death or the primary data cut off (DCO) for the analysis, assessed up to 50 weeks ]PFS is the time from randomisation until the date of objective disease progression as defined by Response Evaluation Criteria In Solid Tumours (RECIST version 1.1) or death (by any cause in the absence of progression). Progression is defined using RECIST (v1.1), as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm.
- Median Progression-Free Survival (Site Read, Investigator Assessment) [ Time Frame: Radiologic evaluations were carried out every 6 weeks from randomization until documented progression, withdrawal of consent, loss to follow up, death or the primary data cut off (DCO) for the analysis, assessed up to 50 weeks ]PFS is the time from randomisation until the date of objective disease progression as defined by Response Evaluation Criteria In Solid Tumours (RECIST version 1.1) or death (by any cause in the absence of progression). Progression is defined using RECIST (v1.1), as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm.
- Overall Survival (OS) [ Time Frame: Following progression survival data was collected every 8 weeks until documentation of death, withdrawal of consent, loss to follow-up or the final data cut-off, whichever occurs first. ]OS is the time from the date of randomisation until death due to any cause. Any subject not known to have died at the time of analysis will be censored based on the last recorded date on which the subject was known to be alive.
- Median Overall Survival (OS) at Time of PFS Analysis [ Time Frame: Baseline and then every 6 weeks after randomization until objective disease progression. OS is then assessed 8 weekly following PFS progression up to PFS analysis data cut off. ]
- Objective Response Rate (ORR) (Site Read Data) [ Time Frame: Radiologic evaluations were carried out every 6 weeks from randomization until documented progression, withdrawal of consent, loss to follow up, death or the primary data cut off (DCO) for the analysis. ]ORR rate is defined as the number (%) of subjects with at least one visit response of Complete Response (CR) or Partial Response (PR) , as defined by Response Evaluation Criteria in Solid Tumours (RECIST v1.1) for target lesions and assessed by CT or MRI. CR, Disappearance of all target lesions; PR, ≥30% decrease in the sum of the longest diameter of target lesions. Data obtained up until progression, or last evaluable assessment in the absence of progression, was included in the assessment of ORR.
- Disease Control Rate (DCR) [ Time Frame: Radiologic evaluations were carried out every 6 weeks from randomization until documented progression, withdrawal of consent, loss to follow up, death or the primary data cut off (DCO) for the analysis. ]DCR is the percentage of patients who achieve disease control at 6 weeks following randomisation. DCR is defined as a Best Objective Response (BOR) of Complete Response, Partial Response or Stable Disease, as defined by Response Evaluation Criteria in Solid Tumours (RECIST v1.1) for target lesions and assessed by CT or MRI. CR, Disappearance of all target lesions; PR, ≥30% decrease in the sum of the longest diameter of target lesions; SD, neither sufficient shrinkage to qualify for PR not sufficient increase to qualify for Progressive Disease (PD); PD, ≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study, and the sum must have shown an absolute increase of ≥5mm
- Improvement in Trial Outcome Index [ Time Frame: At visits 2-8, then every 6 weeks until progression, at progression or treatment discontinuation, and every 8 weeks after progression until PFS analysis data cut off. ]An improvement is defined as a change from baseline of ≥ +6 (0-84 score range). Measured by the Functional Assessment of Cancer Therapy for Lung Cancer (FACT-L) questionnaire.
- Time to Worsening in Trial Outcome Index [ Time Frame: At visits 2-8, then every 6 weeks until progression, at progression or treatment discontinuation, and every 8 weeks after progression until PFS analysis data cut off. ]A worsening is defined as a change from baseline of ≤ -6 (0-84 score range). Measured by the Functional Assessment of Cancer Therapy for Lung Cancer (FACT-L) questionnaire
- Improvement in FACT-L Total Score [ Time Frame: At visits 2-8, then every 6 weeks until progression, at progression or treatment discontinuation, and every 8 weeks after progression until PFS analysis data cut off. ]An improvement is defined as a change from baseline of ≥ +6 (0-136 score range). Measured by the Functional Assessment of Cancer Therapy for Lung Cancer (FACT-L) questionnaire
- Time to Worsening in FACT-L Total Score [ Time Frame: At visits 2-8, then every 6 weeks until progression, at progression or treatment discontinuation, and every 8 weeks after progression until PFS analysis data cut off. ]A worsening is defined as a change from baseline of ≤ -6 (0-136 score range). Measured by the Functional Assessment of Cancer Therapy for Lung Cancer (FACT-L) questionnaire
- Improvement in Lung Cancer Subscale [ Time Frame: At visits 2-8, then every 6 weeks until progression, at progression or treatment discontinuation, and every 8 weeks after progression until PFS analysis data cut off. ]An improvement is defined as a change from baseline of ≥ +2 (0-28 score range). Measured by the Functional Assessment of Cancer Therapy for Lung Cancer (FACT-L) questionnaire
- Time to Worsening in Lung Cancer Subscale [ Time Frame: At visits 2-8, then every 6 weeks until progression, at progression or treatment discontinuation, and every 8 weeks after progression until PFS analysis data cut off. ]A worsening is defined as a change from baseline of ≤ -2 (0-28 score range).
