Skin diseases that do not require systemic treatment (such as vitiligo, psoriasis, hair loss) e. Any other diseases that are not expected to recur if there is no external cause 10. Except for specific cancers under study in this study and locally recurring cancers that have been cured (eg, resected basal cell or squamous cell skin cancer, superficial bladder cancer, cervical or breast carcinoma in situ), before enrollment ≤2 years with other active malignant tumors 11. Any disease requiring systemic treatment with corticosteroids (dose>10mg/day of prednisone or equivalent doses of similar drugs) or other immunosuppressive agents within ≤14 days before randomization Note: Have used any of the following steroids currently or before Patients under the regimen are not excluded: a. Adrenaline replacement steroids (prednisone ≤10mg/day or equivalent dose of similar drugs) b. Local, ophthalmic, intra-articular, intranasal, or inhalation with minimal systemic absorption Corticosteroids c. Prophylactically short-term (≤7 days) use of corticosteroids (for example, to prevent allergy to contrast agents) or to treat non-autoimmune conditions (for example, delayed hypersensitivity reactions caused by contact with allergens) 12. ≤14 days before enrollment, uncontrolled diabetes, potassium, sodium, or corrected calcium laboratory test values >1 grade despite standard drug treatment, or hypoalbuminemia >3 grade 13.Have a history of interstitial lung disease, non-infectious pneumonia or uncontrolled systemic diseases, including pulmonary fibrosis, acute lung diseases, etc.
• 14. Severe chronic or active infection (including tuberculosis infection) that requires systemic antibacterial therapy, antifungal therapy or antiviral therapy in the 14 days before enrollment 15. Known history of HIV infection 16. Major surgery ≤28 days before enrollment Note: Minimally invasive surgery (such as central venous catheterization via peripheral venipuncture [PICC]) is not a major surgery.
• 17. Have received allogeneic stem cell transplantation or organ transplantation 18. There are any of the following cardiovascular risk factors: a. Cardiogenic chest pain ≤28 days before enrollment, defined as moderate pain that restricts daily appliance activities b. Symptomatic pulmonary embolism ≤28 days before enrollment c . Acute myocardial infarction occurred within ≤6 months before enrollment d. A history of heart failure reached New York Heart Association grade III or IV (Appendix 7) within ≤6 months before enrollment e. Before enrollment A ventricular arrhythmia event of grade ≥2 occurred within ≤6 months f. Cerebrovascular accident occurred within ≤6 months before enrollment g. ≤28 days before enrollment, despite the use of antihypertensive drugs, it has not been controlled Hypertension, namely systolic blood pressure ≥160mmHg or diastolic blood pressure ≥100mmHg h. Syncope or seizure occurred ≤28 days before enrollment 19. History of severe hypersensitivity to other monoclonal antibodies or cisplatin or paclitaxel 20. Have received any chemotherapy, immunotherapy (such as interleukin, interferon, thymosin) or any research treatment within 14 days or 5 half-lives (whichever is shorter) before the first administration of the study drug 21. Have taken cancer control herbs within 14 days before the first dose of the study drug 22. Patients whose toxic and side effects caused by previous anti-tumor treatments have not returned to baseline or stable levels, unless they are considered to be AEs that are unlikely to bring safety risks (for example, hair loss, neuropathy, abnormal laboratory test values) 23. Live vaccines were vaccinated ≤28 days before enrollment. Note: Seasonal influenza vaccines are usually inactivated vaccines and are allowed to be used. Intranasal vaccines are live vaccines and are not allowed to be used.
• 24. There are underlying diseases (including abnormal laboratory test values) that are not conducive to the administration of study drugs, or have an impact on drug toxicity or the interpretation of AEs, or reduce or affect the subject's compliance to perform the study, alcohol or drug abuse, or rely.
• 25. At the same time participate in another therapeutic clinical trial.
