Criteria

Inclusion Criteria:

• 1. Provision of informed consent before any study-specific procedures, sampling and analyses.

2. Male or female, age at least 18 years. 3. Histologically confirmed locally advanced or metastatic NSCLC (included patients with stage IIIB, IIIC or IV disease who had relapsed after prior surgery or were newly diagnosed). Patients must be treatment-naïve for locally advanced or metastatic NSCLC. Prior adjuvant and neo-adjuvant therapies are permitted as long as treatment was completed at least 12 months prior to the development of recurrent disease.

4. The tumor harbors 1 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 assessed by central testing using tumor tissue sample or blood sample.

5. At least 1 lesion that has not previously been irradiated, and that can be accurately measured at Baseline as ≥ 10 mm in the longest diameter (except lymph nodes, which must have short axis ≥ 15mm).

6. An Eastern Cooperative Oncology Group (ECOG) performance status equal to 0-1 with no deterioration over the previous 2 weeks and a minimum life expectancy of 12 weeks.

7. Female patients should be using adequate contraceptive measures and should not be breastfeeding at the screening period, during the study, and six months after the last dosing of study. Patient must have a negative pregnancy test prior to start of dosing if of childbearing potential or must have evidence of non-childbearing potential by fulfilling 1 of the following criteria at screening:

1. Postmenopausal defined as age more than 50 years and amenorrhea for at least 12 months following cessation of all exogenous hormonal treatments.

2. Women under 50 years old would be considered postmenopausal if they have been amenorrhea for 12 months or more, following cessation of exogenous hormonal treatments, and with luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels in the postmenopausal range for the laboratory.

3. Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy, but not by tubal ligation.

8. Male patients should be willing to use barrier contraception (i.e., condoms).

Exclusion Criteria:

• 1. Treatment with any of the following:

1. Prior treatment with an EGFR TKI.

2. Major surgery (excluding placement of vascular access) within 4 weeks of randomization.

3. Radiotherapy to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of randomization.

4. Spinal cord compression or brain metastases unless asymptomatic, stable for at least 4 weeks, and not requiring steroids for at least 2 weeks prior to start of study treatment.

5. 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.

2. Any unresolved toxicities from prior therapy greater than Common Terminology Criteria for Adverse Events (CTCAE) Grade 2 at the time of starting study treatment.

3. History of other malignancies, excluding full treated non-melanoma skin cancer, in-situ cancer, or other solid tumors that hadn't recurrent for > 5 years following the end of treatment.

4. Inadequate bone marrow reserve or organ function. 5. Any of the following cardiac criteria:

1. 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).

2. 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).

3. 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.

4. Left ventricular ejection fraction (LVEF) < 50%. 6. Any evidence of severe or uncontrolled systemic diseases (including uncontrolled hypertension and active bleeding diatheses) or active infection. Screening for chronic conditions is not required.

7. Refractory nausea, vomiting, or chronic gastrointestinal diseases, inability to swallow the study drug, or previous significant bowel resection that would preclude adequate absorption of Aumolertinib.

8. Past medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis that required steroid treatment, or any evidence of clinically active interstitial lung disease.

9. Women who are breastfeeding or have a positive urine or serum pregnancy test at the Screening Visit.

10. History of hypersensitivity to any active or inactive ingredient of study drugs (pemetrexed, cisplatin, carboplatin, Aumolertinib) or to drugs with a similar chemical structure or class to Aumolertinib.

11. 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.

12. Any severe and uncontrolled ocular disease that may, in the ophthalmologist's opinion, present a specific risk to the patient's safety.

13. Any disease or condition that, in the opinion of the investigator, would compromise the safety of the patient or interfere with study assessments.
