Outcome Measures

Primary Outcomes (1)

  From enrollment to the end of neoadjuvant therapy at 12 weeks

Secondary Outcomes (8)

• Major pathological response (MPR)

  Pathological detection within 1month after surgery

• Pathological complete response (pCR)

  Pathological detection within 1 month after surgery

• Age ≥ 18 years old.
• Non-small cell lung cancer confirmed by histopathology or cytology, clinical stage II, IIIA or IIIB (N2) assessed by the investigator according to AJCC 8th edition.
• EGFR exon 20 insertion mutation confirmed by an approved local laboratory.
• No disease progression in the past two weeks of signing the informed consent form and a score of 0-1 according to the ECOG criteria, and no significant progression within 2 weeks before the first dose.
• At least one measurable target lesion according to RECIST v1.1.
• Adequate bone marrow and other organ reserve:
• Absolute neutrophil count (ANC) ≥ 1.5 × 109/L
• Platelets ≥ 100 × 109/L
• Hemoglobin ≥ 9 g/dL
• Total bilirubin ≤ 1.5 ×ULN; in patients with Gilbert syndrome, total bilirubin ≤ 3 × ULN
• ALT≤ 2.5 × ULN and AST≤ 2.5 × ULN
• Creatinine ≤ 1.5 × ULN, and creatinine clearance calculated the Cockcroft-Gault method ≥ 60 mL/min
• International normalized ratio (INR) ≤ 1.5 × ULN
• Partial thromboplastin time (APTT) ≤ 1.5 × ULN

You may not qualify if:

• Patients who have received the following treatments must be excluded:
• Any systemic anti-tumor treatment, including radiotherapy;
• Other drugs in the development stage, if the medication does not exceed 28 days and has not undergone any tumor assessment, the medication must be stopped for more than 5 half-lives and the patient can be enrolled after consultation with the investigator.
• Traditional Chinese medicine and other drugs with strong P450 (CYP)3A4 inhibitory or inducing effects are currently being used or cannot be stopped. There must be a washout period of at least 1 week before the first dose.
• A history of other malignant tumors other than lung cancer within 2 years (except for basal cell carcinoma of the skin or in situ cervical cancer that has been adequately treated and has no evidence of recurrence during the screening period).
• Before the first dose, there are adverse events of CTCAE \> 1 grade (except for any degree of alopecia) caused by previous treatment (such as diagnostic puncture, use of other drugs, etc.).
• History of stroke or intracranial hemorrhage within 6 months before the first dose.
• According to the investigator's judgment, the presence of any severe or poorly controlled systemic disease, including any of the following poorly controlled heart-related diseases or abnormalities:
• The resting electrocardiogram shows a calibrated QTc interval (QTcF) \> 470 msec
• The resting electrocardiogram shows any serious abnormalities in heart rhythm, conduction or pattern, such as complete left bundle branch block, third-degree heart block, second-degree heart block, PR interval \> 250 msec
• Any factors that can cause QTcF prolongation or arrhythmia, such as heart failure, hypokalemia, congenital long QT syndrome, family history of QT syndrome or other sudden death diseases under 40 years old, or other diseases known to cause QT prolongation
• Suffering from atrial fibrillation (except for drug-induced and recovered after discontinuation of the drug)
• Myocardial infarction within 6 months before the first dose, New York Heart Association grade 2 congestive heart failure, or arrhythmias that are not well controlled by drugs
• Patients with a history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis requiring steroid hormone treatment, or any clinically active interstitial lung disease, or immune pneumonitis caused by immunotherapy.
• Patients with refractory nausea and vomiting, chronic gastrointestinal diseases, difficulty in swallowing medication, or previous intestinal resection that prevents adequate absorption of sunvozertinib.
