treatment purpose

1, Male or female, at least 18 years or more.
2. NSCLC, of non-squamous histology.

3. Stage IA2 or IA3 disease, based on TNM8 classification.

4. Complete surgical resection (R0) of the primary NSCLC by lobectomy, bilobectomy, segmentectomy or sleeve resection.

5. Complete recovery from surgery at the time of randomisation. Study intervention cannot commence within 4 weeks following surgery. No more than 12 weeks may have elapsed between surgery and randomisation for participants.

6. World Health Organization performance status of 0 or 1.

7. Provision of tumour sample for central pathology assessment of pathologic risk factors and to assess EGFR mutation status prior to randomisation.

8. A tumour which harbours one of the 2 EGFR mutations (Ex19del, L858R) by cobas EGFR Mutation Test v2 (Roche Diagnostics) or FoundationOne test.

9. Minimum life expectancy of > 6 months.

10. Females must be using highly effective contraceptive measures, and must have a negative pregnancy test prior to start of dosing if of child-bearing potential, or must have evidence of non-child-bearing potential. Male subjects must be willing to use barrier contraception.

1. Mixed small cell and non-small cell cancer history.

2. Participants with incomplete (R1/R2) resection, or who have undergone pneumonectomy or only wedge resection.

3. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses; or active infection including HCV and HIV or active uncontrolled HBV infection.

4. History of another primary malignancy, including any known or suspected synchronous primary lung cancer except for malignancy treated with curative intent with no known active disease 5 years or more before the first dose of study intervention and of low potential risk for recurrence.

5. Any of the following cardiac criteria :

- Mean resting QTcF interval > 470ms, obtained from triplicate ECGs performed at screening.

- Any abnormalities in rhythm, conduction, or morphology of resting ECG,

- Any factors that increase the risk of QTcF prolongation or risk of arrhythmic events.

6. History of interstitial lung disease.

7. Inadequate bone marrow reserve or organ function

8. Any unresolved toxicities from prior therapy greater than CTCAE Grade 1 at the time of starting study intervention.

9. Prior treatment with any anticancer therapy for NSCLC (including chemotherapy, radiotherapy, immunotherapy, and EGFR-TKIs).

10. Major surgery or significant traumatic injury within 4 weeks of the first dose of study intervention.

11. Participants currently receiving medications or herbal supplements known to be strong inducers of CYP3A4.

Disease-Free Survival (DFS) in high-risk stratum [ Time Frame: From date of randomisation up to approximately 10 years ]
DFS is defined as the time from the date of randomisation until the date of disease recurrence or date of death (by any cause in the absence of recurrence), whichever occurs first.

Stratification to the high risk stratum will be based on pathologic features assessed by central pathology review during screening.
