  Tislelizumab is a marketed recombinant human anti-PD-1 monoclonal antibody injection, and will be administered by intravenous infusion, Q3W, with 21 days as one treatment cycle at a dosage of 200 mg.
• Препарат Paclitaxel+Carboplatin or Pemetrexed + Cisplatin/Carboplatin
  Paclitaxel+Carboplatin or Pemetrexed + Cisplatin/Carboplatin are widely accepted and common chemotherapy medication. For squamous NSCLC, Paclitaxel+Carboplatin were recommended to be administrated on a 21-day cycle. For nonsquamous NSCLC, Pemetrexed + Cisplatin or Carboplatin were recommended to be administrated on a 21-day cycle.

Критерии исключения

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 the first dose of the study intervention (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;
• Participants with a history of other malignant tumors within 3 years prior to the first dose of the study intervention, 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.;
• Participants who are known to be allergic to any component of SYS6010, Enlonstobart, Tislelizumab or to humanized monoclonal antibody products or ; Paclitaxel/Carboplatin/ Pemetrexed/Cisplatin.
• Previously treated with topoisomerase I inhibitor toxin ADC therapy
