Comparing Stereotactic Body Radiotherapy with Immunochemotherapy for Lung Cancer

Stereotactic Body Radiotherapy Followed by Tislelizumab Plus Platinum-based Chemotherapy Versus Tislelizumab Plus Platinum-based Chemotherapy as Neoadjuvant Therapy in Patients With Resectable Stage Ⅱ-Ⅲ Non-small Cell Lung Cancer: A Phase Ⅲ, Randomized, Multicenter, Prospective Study

Phase 3 Interventional Sun Yat-sen University · NCT06598527

This study is testing whether combining a specific type of radiation therapy with immunochemotherapy can help people with early-stage lung cancer do better than just using immunochemotherapy alone before surgery.

What this trial studies

This clinical trial aims to evaluate the effectiveness and safety of combining neoadjuvant Stereotactic Body Radiotherapy (SBRT) with immunochemotherapy compared to immunochemotherapy alone in patients with resectable stage II-III non-small cell lung cancer (NSCLC). Participants will receive either the combination treatment or immunochemotherapy alone, followed by surgery within a specified timeframe. The study will assess event-free survival and safety outcomes to determine the potential benefits of the combined approach.

Who should consider this trial

Good fit: Ideal candidates are patients with untreated stage IIa-IIIa NSCLC or potentially resectable stage IIIb NSCLC who meet specific health criteria.

Not a fit: Patients with advanced or unresectable lung cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve event-free survival rates for patients with resectable NSCLC.

How similar studies have performed: Previous studies have shown promising results with similar approaches, but this specific combination is being evaluated for the first time in this context.

Eligibility criteria

Inclusion Criteria:

* 1\. Patients voluntarily agree to participate and sign the informed consent; 2. Patients with cytologically/histologically diagnosed (by means of percutaneous lung aspiration biopsy, bronchoscopy, mediastinoscopy, etc.), untreated stage IIa-IIIa (according to the AJCC 8th edition of thoracic tumor staging) non-small cell lung cancer. In addition, patients with potentially resectable stage IIIb (T3-4N2) NSCLC will also be enrolled. All patients are required to receive PET/CT (or chest + upper abdominal CT + brain MRI) at baseline for clinical staging; 3. Pulmonary lesions will be assessed as resectable/potentially resectable by a multiple disciplinary team including thoracic surgeon; 4. Eastern Cooperative Oncology Group Performance Status 0 to 1 5. Requirements for hematology: i, neutrophils ≥ 1500 x 109/L; ii, platelets ≥ 100 x 109/L; iii, hemoglobin \> 9.0 g/dL; iv, serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 40 mL/min; v, aspartate transaminase (AST)/alanine transaminase (ALT) ≤ 3 x ULN; vi, total bilirubin ≤ 1.5 x ULN; vii. forced expiratory volume in the first second (FEV1) ≥ 1.2 L or \> 40% predicted; viii. International Normalized Ratio/activated partial thromboplastin time (INR/APTT) within the normal range; 6. Age 18-75

Exclusion Criteria:

* 1\. Patients with or suspected with autoimmune diseases. Note: patients with vitiligo, type 1 diabetes, hypothyroidism managed with hormone replacement therapy only (Hashimoto's thyroiditis) can be enrolled in the study when there is no clear evidence of recurrence; 2. Patients required systemic corticosteroids treatment (dose \> 10 mg daily prednisolone \[or equivalent\]) or other immunosuppressive drugs within 14 days of enrollment. Note: inhaled or topical corticosteroids, or adrenal replacement therapy (dose \> 10 mg daily prednisolone \[or equivalent\]) are acceptable for patients without apparent autoimmune disease; 3. Historical radiotherapy of chest 4. Active bleeding before treatment 5. Patents with sever heart, lung, liver, or kidney insufficiency 6. Diabetes more than 10-year; unsatisfactory blood glucose control 7. Patients with interstitial lung disease or non-infectious pneumonia 8. EGFR-mutations and ALK-fusion positive NSCLC 9. Patients with other prior malignancies (except skin malignancies other than non-melanoma, and carcinoma in situ at the following sites \[bladder, stomach, colorectal, endometrium, cervix, melanoma, or breast\]) are not eligible for enrollment in this study. However, if the prior malignancies remain in complete response (CR) for ≥ 2 years and no additional anti-cancer therapy is required during the study, such patients are permitted to be enrolled; 10. The patient is medically, psychologically, or physiologically unable to complete the study or to understand the Patient Information Sheet, in the opinion of the investigator; 11. Received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA any other drugs specifically targeting T-cell co-stimulation or immunoregulation pathways; 12. Present active hepatitis B or hepatitis C 13. Patients with positive HIV test results or diagnosed with acquired immunodeficiency disease (AIDS); 14. Hypersensitivity to the investigational product; 15. Pregnant or lactating women.
