An Exploratory Clinical Study of TILs in the Treatment of Recurrent / Refractory Non-small Cell Lung Cancer (NSCLC)

An Exploratory Clinical Study of Autologous Tumor Infiltrating Lymphocytes (TILs) in the Treatment of Recurrent and Refractory Non-small Cell Lung Cancer (NSCLC)

This study is an open, single-arm, dose-escalating phase I exploratory clinical trial to observe the safety, tolerability and preliminary efficacy of different doses of TILs in the treatment of relapsed and refractory NSCLC（Non-small cell lung cancer）.

The study includes 7 stages: ① screening period; ② tissue collection; ③ TILs cell production and preparation; ④ lymphocyte depletion pretreatment; ⑤ TILs cell infusion; ⑥ safety and efficacy evaluation; ⑦ follow-up.

4. The patient's pre-survival period exceeds 3 months;
5. Patients with advanced stage IIIB or above (according to AJCC 8th Edition lung cancer staging criteria), and patients with stage IIIA or above who received targeted drugs or PD-1 treatment then failed;
6. Patients who have received systemic therapy of anti-tumor therapy (including chemotherapy, radiotherapy, immunotherapy, biotherapy or targeted therapy), and whose progress has been confirmed after treatment;
7. At least one measurable target lesion defined by RECIST v1.1 (Response Evaluation Criteria in Solid Tumours);
8. At least one tumor with a diameter of more than 10 mm and a volume of 1.5 cm3 can be resected or biopsied, and TILs can be separated after resection, or TILs can be separated from malignant effusion;
9. Blood routine test reached the following indicators: lymphocyte count ≥ 0.4 × 109 / L, neutrophils ≥ 1.0 × 109 / L, platelet ≥ 60 × 109 / L, hemoglobin ≥ 60g / L;
10. Liver and kidney function: ALT (alanine aminotransferase) or AST (aspartate aminotransferase) index < 2.5 times of normal value; Creatinine clearance rate > 50 ml / min; Total bilirubin < 1.5 times of normal value; Prothrombin time prolongation ≤ 4 s;
11. No heart disease or coronary heart disease, echocardiogram shows normal diastolic function, left ventricular ejection fraction (LVEF) ≥50%, and no serious arrhythmia;
12. Treatment methods for malignant tumors, including radiotherapy, chemotherapy and biological agents (including granulocyte colony-stimulating factor G-CSF, targeted drug therapy, etc.), must be stopped 14 days before obtaining tumor tissue;
13. Female patients with fertility must have a negative pregnancy test;
14. The fertile person or fertile partner must be willing to use an approved and effective contraceptive method during the treatment period and within 12 months after receiving all treatments related to the treatment regimen.
