- Major Pathological Response (MPR) [ Time Frame: From date of randomization to an average of 12 weeks after the first dose ]Defined as ≤10% residual cancer cells in the main tumour, as assessed per central pathology laboratory post-surgery
- Pathological complete response (pCR) [ Time Frame: From date of randomization to an average of 12 weeks after the first dose ]Defined as absence of any residual cancer cells in the dissected tumour samples, including the main tumour and lymph nodes, assessed post-surgery
- Event-free survival (EFS) [ Time Frame: Up to approximately 42 months after the last patient is randomized ]An event is defined as documented disease progression that precludes surgery or requires non-protocol therapy; recurrence or a new lesion, local or distant (a new primary malignancy confirmed by pathology is not considered to be an EFS event.); death due to any cause
- Overall Survival (OS) [ Time Frame: Up to approximately 5.5 years after the last patient is randomized ]Patients will be followed up to approximately 5.5 years after they are randomized.
- Disease free survival (DFS) [ Time Frame: From date of randomization up to approximately 42 months after date of resection ]DFS is defined as the time from the date of surgery until the first date of disease recurrence (local or distant) or date of death due to any cause, whichever occurs first.
- Downstaging [ Time Frame: From date of randomization to an average of 12 weeks after the first dose ]Measured using pathologic mediastinal lymph node evaluation
- Difference between treatment arms in change from baseline in EORTC QLQ-C30 (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 items) [ Time Frame: From randomization to 264 weeks post-surgery ]Assess disease-related symptoms, functioning, and global health status/quality-of-life in patients
- Concordance of EGFRm status between tumour tissue DNA and patient-matched plasma-derived ctDNA [ Time Frame: Baseline ]
- Corcordance of EGFR mutation status between the local and central cobas EGFR mutation test results from baseline tumour samples [ Time Frame: Baseline ]
- PK plasma concentrations of osimertinib [ Time Frame: From the pre-dose of Cycle 2 to post-dose of Cycle 3 (each cycle is 21 days) ]
- Difference between treatment arms in change from baseline in EORTC QLQ-LC13 (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Lung Cancer 13 items) [ Time Frame: From randomization to 264 weeks post-surgery ]Assess lung cancer-associated symptoms and side effects from conventional chemotherapy and radiotherapy
- Cure rate [ Time Frame: From the surgery until 5 years after surgery ]The cure rate is defined as the percentage of people in this study who are still alive and disease free for a certain period of time after they finished the surgery. Here 5-year landmark cure rate will be calculated in the same time as OS analysis.
- Number of adverse events as assessed by CTCAE 5.0 and other clinical variables for safety and tolerability profile of neoadjuvant osimertinib as monotherapy or in combination with chemotherapy prior to surgery compared with chemotherapy alone [ Time Frame: From the time of enrollment to either 28-days after the last dose of last study treatment for patients who do not undergo surgery, or 90-days post-surgery ]Other clinical variables include deaths, laboratory data, vital signs (pulse and BP), ECG, LVEF, ECOG performance status, and ophthalmologic assessment
- MPR using plasma-derived circulating-free tumour DNA (ctDNA) [ Time Frame: From randomization to 5 years post-surgery ]
