Neoadjuvant Immunotherapy for Stage III Non-small Cell Lung Cancer

Summary

This is a phase II, non-randomized, open-label, multi-center study to evaluate the efficacy of neoadjuvant Sintilimab (PD-1 antibody) or combined with chemotherapy as first-line treatment in patients with stage III non-small cell lung cancer (NSCLC).

4. Eastern Cooperative Oncology Group (ECOG) performance-status score of 0 or 1.
5. Life expectancy is at least 12 weeks.
6. At least 1 measurable lesion according to RECIST 1.1.
7. With the feasiblility or anticipated feasiblility after neoadjuvant therapy to receive radical surgery;
8. Patients with good function of other main organs (liver, kidney, blood system, etc.):

   * ANC count ≥1.5×10\^9/L, platelet count ≥100×10\^9/L，hemoglobin ≥90 g/L;
   * the international standard ratio of prothrombin time (INR) and prothrombin time (PT) \< 1.5 times of upper limit of normal (ULN);
   * Partial thromboplastin time (APTT) ≤1.5×ULN;
   * Total bilirubin ≤1.5×ULN;
   * Alanine aminotransferase (ALT) aspartate aminotransferase (AST) ≤2.5×ULN, or ALT and AST ≤5×ULN in the patients with liver metastatic tumor.
9. Patients with normal lung function can tolerate surgery;
10. Without systematic metastasis (including M1a, M1b and M1c);
11. Fertile female patients must voluntarily use effective contraceptives not less than 120 days after chemotherapy or the last dose of Sintilimab (whichever is later) during the study period, and urine or serum pregnancy test results within 7 days prior to enrollment are negative.
12. Unsterilized male patients must voluntarily use effective contraception during the study period not less than 120 days after chemotherapy or the last dose of Sintilimab (whichever is later).

Exclusion Criteria:

1. Non-squamous cell carcinoma with EGFR active mutation positive or ALK rearrangement;
2. Participants who have received any systemic anti-cancer treatment for thymic epithelial tumor, including surgical treatment, local radiotherapy, cytotoxic drug treatment, targeted drug treatment and experimental treatment;
3. Administration of any Chinese medicine against cancer before administration of the drug;
4. Participants with other cancer (excluding cervical carcinoma in situ, cured basal cell carcinoma, bladder epithelial tumor \[including TA and tis\]) within five years before the start of this study;

9. Participants who are allergic to the test drug or any auxiliary materials;
10. Participants with active hepatitis B, hepatitis C or HIV;
11. The vaccine was administered within 4 weeks of the start of the trial;
12. Participants who have undergone major surgery or severe trauma in other systems within 2 months before the start of this trial;
