Treatment with an investigational drug within five half-lives of the compound 7. Participation in another clinical study with an investigational product (IP) during the last 3 weeks before the first day of study treatment 8. Patients who have received prior immunotherapies 9. Patients who have received prior EGFR treatments for lung cancer 10. Patients who have received prior treatment with an EGFR TKI including in the adjuvant setting 11. Patients who have received previous treatment for metastatic or stage IV disease 12. Prior treatment with cytotoxic chemotherapy for advanced NSCLC 13. Patients with a history of cancer that has been completely treated, with no evidence of malignant disease currently cannot be enrolled in the study if their chemotherapy was completed less than 6 months prior and/or have received a bone marrow transplant less than 2 years before the first day of study treatment 14. 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 15. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses or active infection (eg, patients receiving treatment for infection) including hepatitis C and human immunodeficiency virus (HIV), or active uncontrolled Hepatitis B virus (HBV) infection. 16. Patients who have had a surgical procedure unrelated to the study within 14 days or major surgery within 1 month prior to the administration of the study drug 17. Past medical history of interstitial lung disease (ILD), drug-induced ILD, radiation pneumonitis 18. Any of the following cardiac criteria: Mean resting QT interval corrected for heart rate (QTc) more than 470 msec, obtained from 3 ECGs, using the screening clinic ECG machine derived QTc value. Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG e.g. complete left bundle branch block, third degree heart block and second degree heart block. Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalaemia, hypomagnesaemia, hypocalcaemia, 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 19. Spinal cord compression, symptomatic and unstable brain metastases except for those patients who have completed definitive therapy, and have had a stable neurological status for at least 2 weeks after completion of definitive therapy. 20.Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of osimertinib 21.Inadequate bone marrow reserve or organ function 22.Female patients who are breastfeeding 23.Patients currently receiving medications or herbal supplements known to be potent inducers of cytochrome (CYP) 3A4. 24.Patient unwilling to undergo a biopsy at the time of disease progression 25.History of hypersensitivity to active or inactive excipients of osimertinib or drugs with a similar chemical structure or class to osimertinib 26.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 27.Involvement in the planning and/or conduct of the study 28.Previous enrolment in the present study
