Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression-Free Survival (PFS) (Modified Intent-to-Treat [mITT] Set)
Time Frame: Tumor scans performed at screening, every 8 weeks ±1 week up to 48 weeks, and then every 12 weeks ±1 week thereafter until confirmed PD. Assessed up to the DCO date 23-Jun-2024 (a maximum of approximately 2035 days)
The PFS per Response Evaluation Criteria in Solid Tumors 1.1. (RECIST 1.1) using blinded independent central review (BICR) assessments was defined as the time from the date of randomization until the date of objective disease progression (PD) or death (by any cause in the absence of progression) regardless of whether the participant withdrew from therapy or received another anti-cancer therapy prior to progression. The PD was defined as at least a 20% increase in the sum of diameters of target lesions (TLs) and an absolute increase of >=5 millimeters (mm), taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters. Median PFS was calculated using the Kaplan-Meier technique.
Tumor scans performed at screening, every 8 weeks ±1 week up to 48 weeks, and then every 12 weeks ±1 week thereafter until confirmed PD. Assessed up to the DCO date 23-Jun-2024 (a maximum of approximately 2035 days)

Tumor scans performed at screening, every 8 weeks ±1 week up to 48 weeks, and then every 12 weeks ±1 week thereafter until confirmed PD. Assessed up to the DCO date 23-Jun-2024 (a maximum of approximately 2035 days)
Duration of Response (DoR)
Time Frame: Tumor scans performed at screening, every 8 weeks ±1 week up to 48 weeks, and then every 12 weeks ±1 week thereafter until confirmed PD. Assessed up to the DCO date 23-Jun-2024 (a maximum of approximately 2035 days)

The PD was defined as at least a 20% increase in the sum of diameters of target lesions and an absolute increase of >=5 mm, taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters. The PFS12 and PFS18 were defined as the Kaplan-Meier estimate of PFS per RECIST 1.1 as assessed by the Investigator at 12 and 18 months, respectively and both were obtained using the algorithm for the RECIST 1.1 site Investigator tumor data.
Months 12 and 18
Time From Randomization to Second Progression (PFS2)

Serum Concentration of Durvalumab
Time Frame: End of infusion on Cycle 1 Day 1, pre-infusion on Cycles 2 and 4 Day 1 and Month 3 follow-up (each cycle=28 days)

Number of Participants With Anti-Drug Antibody (ADA) Response to Durvalumab
Time Frame: Pre-dose on Day 1 of Cycles 1, 2 and 4 (each cycle=28 days)
Blood samples were collected to determine the presence of ADAs and ADA-neutralizing antibodies (nAb) for durvalumab using validated assays. ADA prevalence was defined as the number of participants with positive ADA result at any time, baseline or post-baseline. ADA incidence was defined as either treatment-induced (post-baseline ADA positive only) or treatment-boosted ADA (baseline positive ADA titer that was boosted to >=4-fold during the study period). Treatment-induced ADA was defined as ADA positive only post-baseline and not detected at baseline. Persistently positive was defined as having at least 2 post-baseline ADA positive assessments with at least 16 weeks between the first and last positive assessment, or ADA positive at the last post-baseline assessment. Transiently positive was defined as having at least 1 post-baseline ADA positive assessment without fulfilling the conditions for persistently positive.
Pre-dose on Day 1 of Cycles 1, 2 and 4 (each cycle=28 days)
Change From Baseline in Patient-Reported Symptoms as Assessed by European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires (EORTC QLQ) at Week 132
Time Frame: Baseline (Day 1) and Week 132
Patient reported outcomes for 5 disease related symptoms was assessed using EORTC QLQ-Core 30 (C30) items questionnaire (fatigue, appetite loss) and EORTC QLQ-Lung Cancer module 13 (LC13) (dyspnoea, cough and pain in chest).An outcome variable consisting of a score from 0 to 100 was derived for each of the symptom scales/symptom items, functional scales, and global health status scale with higher scores on global health status/QoL and functioning scales representing better health status/function, but higher scores on symptom scales/items representing greater symptom severity. An improvement in symptoms were indicated by a negative change in score from baseline. A positive change in score from baseline indicated a deterioration of symptoms. A minimum clinically meaningful change was defined as change from baseline of >=10. Change from baseline in C30: global health status/QoL, physical functioning, fatigue, appetite loss and LC13: dyspnoea, cough and pain in chest are presented.
Baseline (Day 1) and Week 132
Number of Participants With Positive Programmed Death Ligand 1 (PD-L1) Status Based on Overall Survival, Progression-Free Survival and Objective Response Rate
Time Frame: Up to 9 years
Blood samples will be collected for clinical biomarker testing and a tumor specimen will be collected as per tumor specimen collection requirements. The specimen will be evaluated by immunohistochemistry to determine the expression of tumor specific antigens and immune markers. The PD-L1 is a biomarker and data for number of participants with its positive status will be presented.
Up to 9 years
