Brief Summary

This study evaluates the preliminary efficacy and safety of adjuvant therapy with liquid tumor-infiltrating lymphocytes (L-TIL) in combination with tislelizumab in patients with resectable stage II-IIIB non-small cell lung cancer (NSCLC) who underwent surgery after neoadjuvant treatment with an immune checkpoint inhibitor plus platinum-based doublet chemotherapy but did not achieve a pathological complete response (pCR).

Conditions

NSCLC

Outcome Measures

Primary Outcomes (1)

• 2-year Disease Free Survival

  2-year DFS is defined as the proportion of patients who remain free of disease recurrence, second primary malignancy, or death from any cause at 24 months after surgery.

  2 years

Secondary Outcomes (6)

• Disease free survival (DFS)

  Up to 3 years

• Overall survival (OS)

  Up to 5 years

• Adverse event (AE)

  Up to 5 years

• Locoregional Recurrence-Free Survival (LRFS)

  Up to 3 years

• Distant Metastasis-Free Survival (DMFS)

  Up to 3 years

Study Arms (1)

L-TIL Cells Plus Tislelizumab

EXPERIMENTAL

Participants will receive adjuvant therapy with liquid tumor-infiltrating lymphocytes (L-TIL) in combination with tislelizumab. Autologous peripheral blood TILs will be infused 4 times, each at a dose of ≥1 × 10⁹ cells, administered 2-3 days after each tislelizumab infusion. Tislelizumab will be given at 400 mg every 6 weeks for a total of 8 cycles of adjuvant treatment.

Biological: L-TIL cells injection; Drug: Tislelizumab

• Normal bone marrow reserve: neutrophil count ≥1.5×10⁹/L, lymphocyte count ≥0.6×10⁹/L, platelet count ≥100×10⁹/L, hemoglobin ≥90g/L; Normal renal function: serum creatinine ≤1.5 mg/dL and/or creatinine clearance rate ≥60 mL/min; Normal liver function: total bilirubin ≤1.5 times ULN, AST and ALT ≤1.5 times ULN; Normal coagulation function: APTT ≤1.5 times ULN, INR ≤1.5 times ULN, PT ≤1.5 times ULN; Left ventricular ejection fraction (LVEF) ≥50% on echocardiography; Pulmonary function test showing FEV1 ≥60%;
• For non-surgically sterilized or women of childbearing potential, must agree to use medically approved contraception (such as an intrauterine device, contraceptive pills, or condoms) during the study treatment period and for 3 months after the end of treatment; must have a negative serum or urine HCG test within 7 days prior to study entry; must not be breastfeeding;

You may not qualify if:

• Vaccination within 28 days prior to the first dose, except for inactivated vaccines;
• Major surgery within 28 days prior to the first dose;
• History of other malignancies within 5 years prior to screening;
• Unstable or severe concurrent diseases within 6 months prior to the first dose, such as severe/unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction, pulmonary hypertension, life-threatening ventricular arrhythmias requiring maintenance therapy, stroke, and uncontrolled severe seizures;
• Clinically significant active pneumonia or other respiratory system diseases severely affecting lung function at screening;
• Active autoimmune diseases, history of autoimmune diseases, or conditions requiring systemic corticosteroids or immunosuppressive drugs;
• Arterial or venous thrombotic events occurring within 6 months prior to screening;
• History or CT findings indicating active tuberculosis within 1 year prior to enrollment that was untreated;
• Active infections requiring systemic anti-infective treatment;
• Active gastrointestinal bleeding or contraindications to IL-2 use;
• Previous bone marrow transplant or solid organ transplant;
• Other serious acute or chronic medical or psychiatric illnesses (including suicidal ideation or behavior within one year) that may increase the risk associated with participation in the study or administration of the investigational treatment, interfere with the investigational treatment and follow-up, or affect the subject's compliance;
