A Prospective Cohort Study of Neoadjuvant Chemotherapy Plus Sintillumab in the Treatment of Resectable NSCLC

IIT20240507

This study uses a prospective cohort design.Subjects are randomly divided into three groups (A, B, C) before surgery. Group A gets 3 cycles of sintilimab + chemo, Group B gets 2 cycles + 1 cycle, and Group C gets 1 cycle + 2 cycles. Non-squamous NSCLC subjects receive pemetrexed/albumin paclitaxel + platinum, while squamous NSCLC subjects get albumin paclitaxel + platinum.

Have adequate organ and bone marrow function, and the laboratory examination values within 14 days prior to enrollment meet the following requirements (no blood components, cell growth factors, albumin and other intravenous or subcutaneously administered drugs to correct hematological or liver and kidney dysfunction were allowed within the first 14 days of obtaining laboratory tests), as follows: 13. Hematological function was sufficient, defined as absolute neutrophil count ≥ 1.5 × 109 / L, platelet count ≥ 100 × 109 / L, hemoglobin ≥ 100g / L; 14. Full liver function, defined as total bilirubin level ≤ 1.5 × ULN, AST and ALT level ≤ 2.5 × ULN, albumin (ALB) ≥ 35g / L; 15. Renal function was sufficient, serum creatinine (Scr) ≤ 1.5 × ULN, creatinine clearance rate (CrCl) ≥ 60mL / min (calculated by Cockcroft / Gault formula) and urine routine test results showed that urinary protein (UPRO) \< 2 + or 24-hour urinary protein \< 1g; 16. The international normalized ratio (INR) ≤ 1.5 × ULN, and prothrombin time (PT) or activated partial thromboplastin time (APTT) ≤ 1.5 × ULN within 7 days before treatment; 17. For women of childbearing age, urine or serum pregnancy tests were negative for at least seven days prior to the first study drug administration. If the urine pregnancy test is positive, a blood pregnancy test is required; 18. If there is a risk of conception, male and female patients need to use high-efficiency contraception (i.e., the method with an annual failure rate of less than 1 %) and continue until at least 180 days after discontinuation of the trial; Note: If abstinence is the normal lifestyle and preferred contraceptive method of the subjects, abstinence can be accepted as a contraceptive method. Exclusion Criteria: 1. Pathological examination showed that small cell carcinoma, neuroendocrine carcinoma, sarcoma, lymphoepithelioma-like carcinoma, salivary gland tumor and mesenchymal tumor components 2. Tumor invasion of the diaphragm, mediastinum, heart, pericardium, large blood vessels (such as aorta), esophagus, vertebral body 3. pulmonary sulcus tumor 4. Contralateral lung nodules, it need biopsy if clinically suspected 5. Subjects with confirmed or suspected brain metastases 6. Currently participating in an interventional clinical study or treatment with another study drug or study device within 4 weeks prior to randomization 7. Previous use of anti-PD-1, anti-PD-L1, anti-programmed death receptor ligand 2 (PD-L2) or anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) drugs or any other drugs acting on T cell co-stimulation or immune checkpoint pathways (such as OX40, CD137, etc.) and adoptive cellular immunotherapy 8. Received drugs with immunomodulatory effects (including thymosin, interferon, interleukin) within the first 4 weeks of randomization 9. Received live attenuated vaccine within the first 4 weeks of randomization（Or plan to receive live attenuated vaccine during the study period） Note: Acceptance of inactivated vaccine for seasonal influenza is permitted; however, live attenuated influenza vaccine is not allowed 10.
