Who cannot take part

• Patients with meningeal metastasis, brainstem metastasis, spinal cord metastasis and/or compression, or active CNS metastasis. Patients with supratentorial and/or cerebellar metastasis (i.e., without mesencephalon, pons, or medulla involvement) who have received local treatment, have achieved stability for at least 2 weeks prior to randomization (imaging shows no new brain metastasis or enlargement of existing brain metastasis, and all neurologic symptoms have stabilized or returned to normal), and do not require corticosteroid therapy or are receiving prednisone at a daily dose of ≤10 mg or equivalent doses of other corticosteroids, can participate in the study
• AEs caused by prior anti-tumor treatment have not recovered to ≤ Grade 1 (excluding Grade 2 alopecia, peripheral neurotoxicity, and other toxicities judged by the investigator to have no safety risk) according to NCI-CTCAE v5.0
• Patients who have not met the corresponding washout period requirements for the following medications or treatments should be excluded:; Major surgery (excluding needle biopsy)：At least 4 weeks; Small molecule targeted drugs, traditional Chinese medicines with anti-tumor indications, palliative radiation or local therapy：At least 2 weeks; intravenous injection of antibiotics, antifungals, or antivirals：At least 2 weeks; Investigational product and Live attenuated vaccine：At least 4 weeks; Strong CYP3A4 inducers or inhibitors ,OATP1B1 and OATP1B3 inhibitors：At least 2 weeks
• Patients who have a history of ILD/non-infectious pneumonitis treated with corticosteroids in the past, currently have ILD/non-infectious pneumonitis, for whom imaging examinations at screening cannot rule out ILD/non-infectious pneumonitis, or whose pulmonary function test indicates severe ventilatory dysfunction and/or decreased diffusion capacity
• Presence of severe infections within 4 weeks prior to randomization, including but not limited to bacteraemia requiring hospitalisation, severe pneumonia, active pulmonary tuberculosis infection, etc.; presence of active infections requiring systemic antibiotics within 2 weeks prior to randomization
• Pleural effusion or pericardial effusion requiring clinical intervention within 2 weeks prior to randomization
• Histologically or cytologically confirmed combined small cell lung cancer,squamous cell carcinoma, neuroendocrine carcinoma,or carcinosarcoma
• Patients with a history of other malignant tumors within 3 years prior to randomization, except for the following conditions: cured skin basal cell carcinoma or squamous cell carcinoma, superficial bladder cancer, prostate carcinoma in situ, and cervical carcinoma in situ, etc
• Patients who are known to be allergic to any component of SYS6010 or to humanized monoclonal antibody products; allergic to carboplatin, cisplatin, or pemetrexed, or have contraindications for their use
• Imaging examination suggests tumor invasion of the cervical, thoracic, and abdominal great vessels; and the investigator assessed that there was no risk of bleeding
• History of ulcerative colitis or Crohn's disease
• History of immunodeficiency (including positive HIV test, other acquired or congenital immunodeficiency diseases), history of allogeneic stem cell or organ transplant
• Other conditions that the investigator deems unsuitable for participation in this clinical study (such as mental disorders, macular cystoid oedema, severe corneal disorders, uncontrolled or poorly controlled hypertension and diabetes mellitus)
• Previously received systemic anti-tumor therapy for locally advanced or metastatic non-squamous NSCLC other than EGFR TKI; patients who have previously received adjuvant/neoadjuvant chemotherapy and experienced disease progression more than 12 months after the end of treatment are allowed to be included
• History of severe cardiovascular or cerebrovascular disease within 6 months prior to randomization, including but not limited to:; Presence of severe cardiac rhythm or conduction abnormalities, such as ventricular arrhythmia requiring clinical intervention, third-degree atrioventricular block, Fridericia-corrected QT interval > 470 ms (Fridericia formula: QTcF = QT/RR0.33, RR = 60/heart rate); History of myocardial infarction, unstable angina pectoris, aortic dissection, angioplasty, or coronary artery bypass; NYHA class II or higher cardiac failure, LVEF<50% at screening; Stroke or other Grade 3 or higher cardiovascular and cerebrovascular events; Pulmonary embolism
• Previous permanent discontinuation of EGFR-targeted therapy due to skin toxicity, or currently have skin diseases requiring oral or intravenous medication
• Active HBV or HCV infection (hepatitis B surface antigen and/or hepatitis B core antibody positive and HBV DNA copies ≥ 1×104 copies/mL or ≥ 2000 IU/mL, HCV antibody positive and HCV RNA above the lower limit of detection of the analytical procedure).
