5. Voluntarily agreeing to participate in this study and signing the informed consent form.

1. . No prior treatment with chemotherapy, EGFR-TKIs, biological therapy, immunotherapy, or any investigational drug that is considered first line treatment for advanced NSCLC.

2. . Eligible patients are not candidates for definitive surgical resection or radiation of all lesions in the opinion of the treating physician.

3. . All patients must be stable without any systemic (oral or parenteral) corticosteroid or anticonvulsant therapy for at least 2 weeks prior to study treatment. Inhaled non-absorbable and topical corticosteroid use are permitted as indicated.

7. . Patients with measurable CNS lesions must have at least one site of CNS lesion, which has not been previously irradiated, can be accurately measured at baseline as ≥ 10 mm in the longest diameter by MRI, and is suitable for accurate repeated measurements. Measurable extracranial lesions are not required. Patients with non-measurable CNS lesions must have at least one extracranial lesion, which has not been previously irradiated, can be accurately measured at baseline as ≥ 10 mm in the longest diameter (except for lymph nodes which must have a short diameter ≥ 15 mm) by CT/MRI, and is suitable for accurate repeated measurements.

Exclusion Criteria

1. Currently participating or planning to participate in any interventional clinical study for first-line treatment (patients who have participated in non-interventional, real-world studies may still be included).

2. Other reasons that, in the Investigator's opinion, make the patient unsuitable for this study.

1. . Prior treatment with EGFR-TKIs (if EGFR-TKIs were used as adjuvant therapy, patients may be enrolled if the time from discontinuation to relapse meets the following requirements: >6 months for Cohort A, and >3 months for Cohorts B and C).

2. . Positive for T790M mutation documented by central or local laboratory using an approved or validated test method, or documented positive KRAS or cMET.

3. . Patients who have received any investigational drug, biological therapy, or immunotherapy for their malignant tumors within the past 21 days.

4. . Patients who have had a major surgical procedure (excluding the need for placement of vascular access or a CNS shunt), or significant traumatic injury within 4 weeks of the first dose of study treatment, or have an anticipated need for major surgery during the study.

5. . Presence of only leptomeningeal metastases (LM) disease confirmed by MRI and/or positive cerebrospinal fluid (CSF) pathology, with no brain metastases (BM).

6. . Prior radiation therapy for CNS metastases that involves measurable or non-measurable sites of disease to assess efficacy.

7. . Patients who have received radiation to more than 30% of the bone marrow within 2 weeks before the first dose of study treatment.

8. . Patients currently receiving (or unable to stop use at least 1 week prior to receiving the first dose of study treatment) certain medications or herbal supplements that are known to be potent inhibitors or inducers of CYP3A4/5 (see Appendix A).

9. . Unmanageable nausea and vomiting, chronic gastrointestinal diseases, or prior gastric resection or surgical procedure that may interfere with adequate absorption of study drug.

10. . History of concurrent and/or other active malignant tumors requiring treatment within 5 years of study treatment, excluding prior treated squamous cell carcinoma or basal cell carcinoma or carcinoma in situ.

11. . History of any type of documented interstitial lung disease or radiation pneumonitis.

2. Platelet count <100 × 109/L (Transfusion-dependent patients are excluded from this study).

3. Hemoglobin <90 g/L.

6. Total bilirubin > 1.5 times the ULN in the absence of metastases to liver or >3 times the ULN in the presence of documented Gilbert's syndrome (unconjugated hyperbilirubinemia) or metastases to liver.

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

8. If bone metastases are present and liver function is otherwise considered adequate by the Investigator, then isolated elevated alkaline phosphatase (ALP) is not an exclusion criterion.

18. . History of hypersensitivity to active or inactive excipients of the study drug or drugs with a similar chemical structure or class to the study drug.

19. . Judgment by the Investigator that the patient should not participate in the study if the patient is unwilling to comply with all study procedures and treatment.
