Primary Outcome Measures :
  1. Median Progression Free Survival (PFS) (Months) [ Time Frame: At baseline and every 6 weeks for the first 18 months and then every 12 weeks relative to randomisation until progression (approximately 11.5 months) ]
    Progression-free survival was defined as the time from randomization until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the participant withdrew from randomized therapy or received another anti-cancer therapy prior to progression and was used to assess the efficacy of single agent osimertinib compared with SoC EGFR-TKI therapy as measured by PFS.

  2. Percentage of Participants in Progression Free Survival at 6, 12, and 18 Months [ Time Frame: At baseline and every 6 weeks for the first 18 months and then every 12 weeks relative to randomisation until progression (approximately 11.5 months) ]
    Progression-free survival was defined as the time from randomization until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the participant withdrew from randomized therapy or received another anti-cancer therapy prior to progression and was used to assess the efficacy of single agent osimertinib compared with SoC EGFR-TKI therapy as measured by PFS.


Secondary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: At baseline and every 6 weeks for the first 18 months and then every 12 weeks relative to randomisation until progression (approximately 11.5 months) ]
    ORR was defined as the number (%) of patients with measurable disease with at least 1 visit response of Complete response (CR) or Partial response (PR) and it was used to further assess the efficacy of osimertinib compared with SoC EGFR-TKI therapy

  2. Duration of Response (DoR) [ Time Frame: At baseline and every 6 weeks for the first 18 months and then every 12 weeks until objective disease progression (approximately 11.5 months) ]
    Duration of response was defined as the time from the date of first documented response until the date of documented progression or death in the absence of disease progression and was used to further assess the efficacy of osimertinib compared with SoC EGFR-TKI therapy.

  3. Disease Control Rate (DCR) [ Time Frame: At baseline and every 6 weeks for the first 18 months and then every 12 weeks until objective disease progression (approximately 11.5 months) ]
    The DCR was defined as the percentage of participants who had a best overall response (BOR) of Complete response (CR), Partial response (PR) or Stable disease (SD) ≥6 weeks prior to any Progressive disease (PD) event and was used to further assess the efficacy of osimertinib compared with SoC EGFR-TKI therapy.

  4. Depth of Response [ Time Frame: At baseline and every 6 weeks for the first 18 months and then every 12 weeks until objective disease progression (approximately 11.5 months) ]
    The Depth of response was defined as the relative change in the sum of the longest diameters of Response Evaluation Criteria in Solid Tumors (RECIST) Target lesions (TLs) at the nadir, in the absence of new lesions (NLs) or progression of Non-target lesions (NTLs), compared to baseline and was used to further assess the efficacy of osimertinib compared with SoC EGFR-TKI therapy

  5. Overall Survival (OS)- Number of Participants With an Event [ Time Frame: From first dose to end of study or date of death from any cause, whichever comes first, assessed every 6 weeks (approximately 29 months) ]
    Overall survival was defined as the time from the date of randomisation until death from any cause and was used to further assess the efficacy of osimertinib compared with SoC EGFR-TKI therapy

  6. Plasma Concentrations of AZD9291 [ Time Frame: Blood samples collected from each participant at pre-dose, 0.5 to 2 hours, and 3 to 5 hours post-dose on Day 1 Cycle 1, and every other cycle thereafter up to and including Cycle 13 (approximately 9 months) ]
    To characterise the pharmacokinetics (PK) of osimertinib

  7. Plasma Concentrations of Metabolites AZ5104 [ Time Frame: Blood samples collected from each participant at pre-dose, 0.5 to 2 hours, and 3 to 5 hours post-dose on Day 1 Cycle 1, and every other cycle thereafter up to and including Cycle 13 (approximately 9 months) ]
    To characterise the pharmacokinetics (PK) of osimertinib metabolite AZ5104.

  8. Plasma Concentrations of Metabolite AZ7550 [ Time Frame: Blood samples collected from each participant at pre-dose, 0.5 to 2 hours, and 3 to 5 hours post-dose on Day 1 Cycle 1, and every other cycle thereafter up to and including Cycle 13 (approximately 9 months) ]
    To characterise the pharmacokinetics (PK) of osimertinib metabolite AZ7550.

  9. Participants Reported Outcome by Cancer Therapy Satisfaction Questionnaire 16 Items (CTSQ-16 Questionnaire) [ Time Frame: Questionnaire completed in cycle 2 and 3, prior to Week 6 scan (approximately 2 months) ]
    The CTSQ-16 was a 16-item questionnaire measuring 3 domains related to participant's satisfaction with cancer therapy: Expectations of therapy, Feelings about side effects, and Satisfaction with therapy. Scores ranged from 0 to 100 for each domain, with a higher score associated with the best outcome on each domain. The three domains of interest were separately analysed using an ANCOVA stratified by race (Asian versus Non-Asian) and mutation type (Ex19del versus L858R). The results of the analyses were presented in terms of mean together with standard deviation.

  10. Change From Baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life (QLQ) Questionnaires Lung Cancer 13 (QLQ-LC13) [ Time Frame: Questionnaires completed at baseline, first 9 months, and at week 1, 2, 3, 4, 5, 6, 12, 18, 24, 30 and 36 ]
    The EORTC QLQ-LC13 was a lung-cancer-specific module comprising 13 questions to assess lung cancer symptoms (cough, haemoptysis, dyspnoea, and site-specific pain [pain in chest, pain in arm or shoulder, and pain in other parts); treatment related side-effects (sore mouth, dysphagia, peripheral neuropathy, and alopecia); and pain medication. Except for a multi-item scale for dyspnoea, all were single items. An outcome variable consisting of a score from 0 to 100 was derived for each of the symptom scales/symptom items. Higher scores on the global health status/QoL and functioning scales indicated better health status/QoL and better function. Higher scores on the symptoms scales indicated greater symptom burden. The results of the analyses were presented in terms of a least squares mean together with its associated 95% profile likelihood CI.

  11. Change From Baseline in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 Items (EORTC QLQ-C30) [ Time Frame: Questionnaires completed at baseline, first 9 months, and at week 6, 12, 18, 24, 30, and 36. ]
    The EORTC QLQ-C30 cancer-specific questionnaire consisted of 30 questions, which were combined to produce 5 functional scales (Physical, Role, Cognitive, Emotional, Social); 3 symptom scales (Fatigue, Pain, Nausea/Vomiting); 6 individual items (dyspnoea, insomnia, appetite loss, constipation, diarrhoea, and financial difficulties); and a global measure of health status/QoL. An outcome variable consisting of a score from 0 to 100 was derived for each of the symptom scales/symptom items, the functional scales, and the global health status/QoL scale in the EORTC QLQ-C30. Higher scores on the global health status and functioning scales indicated better health status/function. Higher scores on the symptoms scales indicated greater symptom burden. The results of the analyses were presented in terms of a least squares mean together with its associated 95% profile likelihood CI.
