Eligibility Criteria
-----------------
Inclusion Criteria: Any patient who meets all of the following inclusion criteria will qualify for entry into the study: Male or female, aged at least 18 years. Histologically confirmed diagnosis of primary non small lung cancer (NSCLC) on predominantly non-squamous histology. Brain examination must be done prior to surgery as it is considered standard of care. Patients are pathologically confirmed to be stage I after operation, containing solid, micropapillary, and/or complex gland components ≥10%. Confirmation by the central laboratory that the tumour harbours one of the 2 common EGFR mutations known to be associated with EGFR-TKI sensitivity (Ex19del, L858R), either alone or in combination with other EGFR mutations including T790M. Providing paraffin embedded section(10-15sheets),wax blocks or fresh frozen tissues. Complete surgical resection of the primary NSCLC is mandatory. All gross disease must have been removed at the end of surgery. All surgical margins of resection must be negative for tumour. World Health Organization Performance Status of 0 to 1. Women of childbearing age should take appropriate contraceptive measures from screening to 3 months after stopping the study treatment and should not breastfeed. Before starting the administration, the pregnancy test was negative. Male patients should be willing to use barrier contraception from screening to stopping study treatment for 3 months.(i.e., condoms). For inclusion in study, patient must provide a written informed consent. ≤10 weeks between surgery and treatment period Exclusion Criteria: Any patient who meets any of the following exclusion criteria will not qualify for entry into the study: Treatment with any of the following: Pre-operative or post-operative or planned radiation therapy for the current lung cancer Pre-operative (neo-adjuvant) platinum based or other chemotherapy Prior treatment with neoadjuvant or adjuvant EGFR-TKI at any time Any other anti-tumor treatment for lung cancer(Including proprietary Chinese patent medicine with anti-tumor effects and anti-tumor immunotherapy, etc.) Major surgery (excluding placement of vascular access) within 4 weeks of the first dose of study drug. Treatment with an investigational drug within five half-lives of the compound or any of its related material. Medications that are predominantly CYP3A4 strong inhibitors or inducers or sensitive substrates of CYP3A4 with a narrow therapeutic range within 7 days of the first dose of study drug.. Patients who have had only segmentectomies or wedge resections History of other malignancies, except: adequately treated non-melanoma skin cancer, curatively treated in-situ cancer, or other solid tumours curatively treated with no evidence of disease for > 5 years following the end of treatment. Any unresolved toxicities from prior therapy greater than CTCAE Grade 1 at the time of starting study treatment with the exception of alopecia and Grade 2, prior platinum-therapy related neuropathy. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses; or active infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV). Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product, or previous significant bowel resection that would preclude adequate absorption of Aumolertinib. Any of the following cardiac criteria: Mean resting corrected QT interval (QTc) > 470 ms obtained from 3 electrocardiograms (ECGs), using the screening clinic's ECG machine and Fridericia's formula for QT interval correction (QTcF). Any clinically important abnormalities in rhythm, conduction, or morphology of the resting ECG (e.g., complete left bundle branch block, third-degree heart block, second-degree heart block, PR interval > 250 ms). Any factors that increase the risk of QTc prolongation or risk of arrhythmic events, such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age in first degree relatives or any concomitant medication known to prolong the QT interval. Past medical history of ILD, drug-induced ILD, radiation pneumonitis which required steroid treatment, or any evidence of clinically active ILD. Inadequate bone marrow reserve or organ function. History of hypersensitivity to any active or inactive ingredient of Aumolertinib, or to drugs with a similar chemical structure or class to Aumolertinib. Any severe and uncontrolled ocular disease that may, in the ophthalmologist's opinion, present a specific risk to the patient's safety. Judgment by the Investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions, and requirements. Any disease or condition that, in the opinion of the Investigator, would compromise the safety of the patient or interfere with study assessments.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 2-year Disease free survival (DFS) rate | Defined as the proportion of patients alive and disease free at 2 years,estimated from Kaplan Meier plots of the primary endpoint of DFS at the time of the primary analysis | From date of treatment start until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 3-, 4-, and 5-year DFS rate | Defined as the proportion of patients alive and disease free at 3, 4 and 5 years, respectively, estimated from Kaplan Meier plots of the primary endpoint of DFS at the time of the primary analysis. | From date of treatment start until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months | 
| Overall Survival (OS) | Defined as the time from the date of treatment start until date of death due to any cause | Start of study drug to Survival Endpoint through study completion, an average of 5 years, assessed up to 60 months | 
| Patient health-related quality of life and symptoms (HRQoL) by SF-36v2 Health Survey | Defined as a patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section and the scores range from 0-100. A score of 0 is equivalent to maximum disability and a score of 100 is equivalent to no disability. | From date of treatment start until treatment completion or discontinuation, assessed up to 60 months |
