• Failure of prior 3 generations EGFR TKI or treatment naive
• ECOG status score 0-1, life expectancy ≥12 weeks
• No central nervous system symptoms during screening, no need for corticosteroids or dehydration diuretic treatment for at least 4 weeks before the first dosing. If the patient with brain metastasis has received radiotherapy or surgery, there is a washout period of ≥2 weeks before the first use of DZD6008 and ensure that the AE related to radiotherapy or surgery has recovered to ≤ 1 grade
• Presence of measurable lesions defined by RECIST 1.1

• Histology mixed with small cell lung cancer (SCLC) or with SCLC transformation
• History of malignant tumor within 2 years (except for basal cell carcinoma of the skin or cervical cancer in situ that has been adequately treated; other tumors that have been tumor-free for more than 2 years and are expected to survive for more than 2 years, which needs to be discussed with Dizal clinical research physicians)
• Presence of severe or uncontrollable systemic diseases, including poorly controlled hypertension, bleeding diseases
• Presence of persistent or active infections, including but not limited to hepatitis B, hepatitis C and human immunodeficiency virus infection (HIV)
• Patient history of interstitial lung disease (ILD), drug-induced ILD, radiation pneumonitis requiring steroid hormone treatment, or any clinically active ILD, immunotherapy-related pneumonitis

• Any of the following heart-related diseases or abnormalities:; QT interval (QTc) >470 msec after calibration of 12-lead ECG at rest during the screening period; Any serious abnormalities of heart rate, conduction or pattern shown on the ECG at rest, such as complete left bundle branch block, third degree heart block, second degree heart block, PR interval >250 msec; Any disease or condition that can cause QTcF prolongation or arrhythmia, such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome, or family members with a history of sudden death under the age of 40; Severe cardiovascular diseases such as myocardial infarction, unstable angina or congestive heart failure, cerebrovascular accident (such as history of stroke or intracranial hemorrhage) within 6 months before the first dose; History of deep vein thrombosis or pulmonary embolism within 4 weeks before the first dose (excluding non-obstructive catheter-related thrombosis)
