Brief Summary

To investigate the efficacy and safety of neoadjuvant treatment with Tislelizumab combined with chemotherapy for initially unresectable N2/III non-small cell lung cancer.

Detailed Description

This study is a prospective, single-arm, single-center phase II clinical trial to investigate the efficacy and safety of neoadjuvant treatment with tirilizumab in combination with chemotherapy in patients with initially inoperable stage III/N2 non-small cell lung cancer.

Patients with stage III/N2 non-small cell lung cancer that is initially inoperable and clearly staged and meets the enrollment criteria will receive 3 cycles of tirilizumab (200 mg) in combination with chemotherapy and will be evaluated by imaging of their tumor status. After MDT evaluation patients will either undergo surgery or be withdrawn from the study and receive a combination of radiotherapy and chemotherapy, with postoperative adjuvant therapy at the discretion of the physician. The primary endpoint of this study is the surgical conversion rate; secondary endpoints include MPR, pCR, safety, and EFS.

8. Measurable lesions (according to the RECIST 1.1 version)

9. Subject must understand and voluntarily sign informed consent prior to any study-related evaluation

Exclusion Criteria

1. The patient presents with a confirmed or suspected autoimmune disorder.

• Note: Patients with vitiligo, type I diabetes mellitus, or Hashimoto's thyroiditis who are hypothyroid but require only hormone replacement therapy may be included in the study if there are no obvious signs of relapse

2. Patients must have undergone systemic corticosteroid treatment (≥10mg prednisolone [or equivalent]/day) or received other immunosuppressive medications within 14 days prior to enrollment.

• Note: Inhaled or topical corticosteroids and adrenal hormone replacement therapy (≥10mg prednisolone [or equivalent]/day) can also be accepted for individuals lacking clear evidence of autoimmune disorders

3. Patients with grade 3 or 4 interstitial lung disease

4. Have other malignant tumors and need anti-tumor therapy

5. Patients with previous malignancies (except skin malignancies other than melanoma, and in situ cancers of the following sites (bladder, stomach, colorectal, endometrial, cervix, melanoma, or breast) were not included in the study. Unless the malignancy has been in complete remission for two years or more and no additional antitumor therapy is required during the study period

6. The investigator believes that the patient is medically, psychologically, or physically incapable of completing this study or of understanding the patient handbook information

7. Previously received anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA, and other drugs targeting T-cell co-stimulation or immune regulatory pathways

8. Presence of active Hepatitis B or C
