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) = 40%.

• 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.

• Inadequate bone marrow reserve or organ function, as demonstrated by any of the following laboratory values:

1. Absolute neutrophil count (ANC) <1.5×109 / L

2. Platelet count <100×109 / L

3. Hemoglobin <90 g/L(<9 g/dL)

4. Alanine aminotransferase > 2.5 × upper limit of normal (ULN) if no demonstrable liver metastases or > 5 × ULN in the presence of liver metastases.

5. Aspartate aminotransferase (AST) > 2.5 × ULN if no demonstrable liver metastases or > 5 × ULN in the presence of liver metastases.

6. Total bilirubin (TBL) > 1.5 × ULN if no liver metastases or > 3 × ULN in the presence of documented Gilbert's Syndrome (unconjugated hyperbilirubinemia) or liver metastases.

7. Creatinine > 1.5 × ULN concurrent with creatinine clearance < 50 mL/min (measured or calculated by the Cockcroft-Gault equation); confirmation of creatinine clearance is only required when creatinine is > 1.5 × ULN.

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

• History of hypersensitivity to any active or inactive ingredient of Almonertinib, or to drugs with a similar chemical structure or class to Almonertinib.

• Patients who are allergic to pemetrexed or any other component of the preparation, carboplatin or other platinum containing compounds.

• Patients with contraindications of pemetrexed and carboplatin.

• 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.

Primary	Progression Free Survival (PFS)	To assess the efficacy of Almonertinib compared with Almonertinib Plus carboplatin and pemetrexed as first line therapy to EGFRm+, locally advanced or metastatic NSCLC patients by assessment of progression free survival (PFS) using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).	From baseline, then every 6 weeks, until disease progression or discontinuation from study. From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months.
Secondary	Assess the anti-tumor activity: OS	Overall survival (OS)	Start of study drug to Survival Endpoint through study completion, an average of 3 years.
Secondary	Assess the anti-tumor activity: ORR	ORR is defined as the percentage of patients who have at least 1 response of CR or PR prior to any evidence of progression assessed up to 24 months	From baseline, then every 6 weeks, until disease progression or discontinuation from study. ORR is defined as the percentage of patients who have at least 1 response of CR or PR prior to any evidence of progression assessed up to 24 months.
Secondary	Assess the anti-tumor activity: DCR	Disease control rate (DCR)	From baseline, then every 6 weeks, until disease progression or discontinuation from study. The DCR is defined as the proportion of patients with a best overall response of CR, PR, or SD assessed up to 24 months.
Secondary	Assess the anti-tumor activity: DoR	Duration of response (DoR)	DoR is defined as the time from the date of first documented response until the date of documented progression or death in the absence of disease progression assessed up to 24 months.
