Eligibility
Key inclusion criteria
1. Provided written informed consent
2. Has reached the age of majority in the country of treatment (i.e. = 18 years in Australia; = 21 years in Singapore)
3. Histological or cytological documented NSCLC
4. Metastatic NSCLC, not amenable to curative surgery or curative radiotherapy
5. Brain metastases that meet the following criteria;

1. = 10 lesion/s visible and measurable on protocol screening MRI;

* At least one brain metastases able to be treated with SRS
* Definite but small brain metastases not for SRS treatment due to size, as per physician discretion, are included in the total
* Equivocal small lesions are not included in the total
2. No single brain metastasis exceeding 30mm longest diameter
3. Total brain metastasis volume = 15cc;

- Total brain metastases volume on protocol screening MRI should be using the formula (4/3) x (3.14159265359) x (1/2 x size lesion in centimetre)3. Table 1: Brain metastases volume estimates provides an estimate of the volume of brain metastases based on the size of the lesion
4. Diagnosed de novo (i.e. at the same time with a new diagnosis of NSCLC) or developed as a new site of progression while on first line EGFR TKI

NOTE: Surgery as part of local practice for the management of brain metastasis is allowed but must be completed between 2 to 4 weeks prior to randomisation. Patients must still fulfil criteria 5a, 5b and 5d pre-surgery, and have at least one target lesion post-surgery to be eligible for the study. Lesions that are partially or completely resected should not be used as a target lesion for MRI assessment.
6. Documented EGFR mutation;

1. Patients who developed brain metastases as a site of disease progression while on first line EGFR TKIs must have T790M mutation.
2. Documented EGFR mutation (at any time since the initial diagnosis of NSCLC) known to be sensitive to Osimertinib - These include exon 19 del; L858R (exon 21); G719X (exon 18); L861G (exon 21); S768I (exon 20) and T790M (exon 20) NOTE: Mutation analysis is to be done as per local practice. Please see section 7.1.1 for the recommended clinical practice for analysis.
7. Are one of the following cohorts:

1. First-line metastatic cancer: All newly diagnosed participants with documented sensitising EGFR mutation (criterion 6) and intracranial metastasis (criterion 5), with/without extracranial disease
2. Second-line metastatic cancer (T790M+): Participants who progressed after first-line 1st or 2nd generation EGFR TKI therapy with intracranial progression (criterion 5), with/without extracranial disease and have documented T790M mutation
3. Second-line metastatic cancer (T790M-): Participants with no T790M mutation who progressed after first-line 1st or 2nd generation EGFR TKI therapy with intracranial progression (criterion 5) but has no extracranial disease
4. Second-line metastatic cancer (T790M-): Participants with no T790M mutation who progressed after first-line 1st or 2nd generation EGFR TKI therapy with intracranial progression (criterion 5) but has stable extracranial disease
8. Karnofsky performance status 60-100 (ECOG performance status =2) with no deterioration over the previous 2 weeks and a minimum life expectancy of 12 weeks
9. Female patients who;

1. are willing to use adequate contraceptive measures until 6 weeks after the final dose of study treatment
2. are not breast feeding
3. have a negative pregnancy test prior to the start of dosing if of child bearing potential or have evidence of non-child bearing potential by fulfilling one of the following criteria at screening:

i. Post-menopausal defined as aged more than 50 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments ii. Women under 50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and with Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) levels in the post-menopausal range for the institution iii. Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy or bilateral salpingectomy but not tubal ligation
10. Male patients who are willing to use barrier contraception (i.e. condoms) until 4 months after the final dose of study treatment

Key exclusion criteria
Exclusion criteria:

1. Treatment with any of the following:

1. Prior systemic therapy for patients with newly diagnosed metastatic NSCLC and brain metastases de novo.

2. Prior whole brain radiotherapy (WBRT)
3. Radiologically progressive brain metastasis that underwent prior SRS (second line patients)
4. Previous treatment with Osimertinib or a 3rd generation EGFR TKI.

Screening for chronic conditions is not required.
8. 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.

2. Any clinically important abnormalities in rhythm, conduction or morphology of resting ECG e.g. complete left bundle branch block, third degree heart block or second degree heart block.
3. Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, electrolyte abnormalities (including: Serum/plasma potassium < LLN; Serum/plasma magnesium < LLN; Serum/plasma calcium < LLN), 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.
10. Patients with congenital long QT syndrome (CLQTS)
11. Past medical history of Interstitial Lung Disease (ILD), drug-induced ILD, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease.
12. Inadequate bone marrow reserve or organ function as demonstrated by any of the following laboratory values:

1. Absolute neutrophil count < 1.5 X 109/L
2. Platelet count < 100 X 109/L
3. Haemoglobin < 90 g/L
4. Alanine aminotransferase (ALT) > 2.5 times the upper limit of normal (ULN) if no demonstrable liver metastases or > 5 times ULN in the presence of liver metastases
5. Aspartate aminotransferase (AST) > 2.5 times ULN if no demonstrable liver metastases or > 5 times ULN in the presence of liver metastases.
6. Total bilirubin > 1.5 times ULN if no liver metastases or > 3 times ULN in the presence of documented Gilbert's Syndrome (unconjugated hyperbilirubinemia) or liver metastases.
7. Creatinine > 1.5 times ULN concurrent with creatinine clearance < 50ml/min (measured or calculated by Cockcroft and Gault equation); confirmation of creatinine clearance is only required when creatinine is > 1.5 times ULN.
13. History of hypersensitivity of drugs with a similar chemical structure or class to Osimertinib or any excipients of these agents.
14. Involvement in the planning and conduct of the study
15. Judgement 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.
