Clinical Trial Summary

To evaluate the efficacy and safety adebrelimab in Combination with chemotherapy after 3 cycles as neoadjuvant therapy and surgery or chemoradiotherapy based on MDT compared with adebrelimab after chemoradiotherapy in potentially operable stage III NSCLC.

Description:

In recent years, tumor immunotherapy has become an important means of clinical treatment of tumor. The emergence of immunotherapy has provided a new direction for the exploration of neoadjuvant therapy for non-small cell lung cancer. The purpose of this study is to compare the use of adebrelimab in patients with stage III potentially resectable locally advanced NSCLC (non-small cell lung cancer). The study will directly compare the curative chemoradiotherapy plus immune maintenance therapy model (Pacific model) with the neoadjuvant immune therapy plus curative surgery plus immune maintenance therapy model (Keynote-671 model). This comparison aims to provide a basis for determining treatment plans for patients with locally advanced NSCLC.

Recruitment information / eligibility

• Status: Recruiting
• Enrollment: 92
• Est. completion date: December 31, 2027
• Est. primary completion date: May 19, 2027
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years to 75 Years

Eligibility

Inclusion Criteria:

• 1. Age 18-75 years old;

• 2. Histologically or cytologically confirmed non-small cell lung cancer. If the pathological type of the patient is adenocarcinoma, genetic testing should be performed to exclude EGFR/ALK mutations. Tumor tissue should be the first choice for genetic testing. If sufficient tumor tissue is not available, genetic testing using serum can be performed.

• 3. According to AJCC 8th Edition, the patient had stage IIIA-IIIB (T1-4N2M0). N2 was a non-giant type with lymph node diameter =3cm and no invasion or exocapsular invasion. Pathological biopsy of mediastinal lymph nodes is recommended to be clear, and patients without pathology should at least meet the short diameter of enhanced chest CT =1cm and high metabolism of PET-CT.

• 4. All lesions (including primary lesions and lymph nodes/metastases evaluated as metastases) of the patient should be evaluated jointly by surgeons, radiologists, and radiologists to be potentially resectable.

• 5. Subjects must have measurable target lesions (according to RECIST 1.1 criteria);

• 6. ECOG behavior status score 0-1;

• 7. No previous history of other malignant tumors;

• 8. Never received anti-tumor therapy such as surgery, radiotherapy, chemotherapy, targeted therapy and immunotherapy related to non-small cell lung cancer;

• 9. The patient should have adequate cardiopulmonary function: FEV1 and DLCO of the patient were =50% of the predicted value, and the ultrasonography suggested LVEF=55%, and no clear signs of heart failure and severe coronary artery stenosis were found in various tests. The cardiopulmonary function was assessed by the surgeon as being able to tolerate surgical treatment.

• 10.The functional level of all vital organs must meet the following requirements:

1. Bone marrow: absolute neutrophil count (ANC) =1.5× 109/L, platelet =100 × 109/L, hemoglobin =9 g /dl;

2. Good coagulation function: defined as International standardized ratio (INR) or prothrombin time (PT) =1.5 times ULN;

3. Liver: total bilirubin =1.5 times the upper limit of normal, aspartate aminotransferase (AST) and alanine aminotransferase (ALT)=2.5 times the upper limit of normal;

4. Kidney: serum creatinine =1.25 times the upper limit of normal or creatinine clearance (calculated by Cockcroft-Gault formula) =60 ml/min;

• 11. Fertile men and women of childbearing age must consent to effective contraceptive use from the time they sign the master informed consent until 180 days after the final administration of the study drug. Women of reproductive age include premenopausal women and women within 2 years after menopause. Pregnancy test results of women of reproductive age must be negative within = 7 days before the first study drug administration;

• 12. Voluntary participation in clinical research; Fully understand and know this study and sign ICF (Informed Consent).

Exclusion Criteria:

• 1. All lesions could not be completely resected by surgery;

• 2. Have any active autoimmune disease or history of autoimmune disease (such as uveitis, enteritis, hepatitis, pituitaritis, vasculitis, myocarditis, nephritis, hyperthyroidism, hypothyroidism (may be included after hormone replacement therapy), tuberculosis); Patients with complete remission of childhood asthma without any intervention or vitiligo in adulthood could be included, but patients requiring medical intervention with bronchodilators could not be included;

• 3. Have a congenital or acquired immune deficiency, such as human immunodeficiency virus (HIV) infection, active hepatitis B (HBV DNA = 500 IU/ml), hepatitis C (HCV antibody positive and HCV-RNA above the lower detection limit of analytical methods), or co-infection with hepatitis B and hepatitis C;

• 4. There is a third lacunar effusion that is difficult to control, such as a large amount of pleural effusion or ascites or pericardial effusion;

• 5. Subjects requiring systemic therapy with corticosteroids (>10 mg/ day of prednisone or equivalent) or other immunosuppressants within 14 days prior to initial medication. In the absence of active autoimmune disease, inhaled or topical corticosteroids are permitted, as well as adrenal hormone replacement therapy at doses > 10 mg/ day of prednisone efficacy;

• 6. Subjects who have been treated with anti-tumor vaccine or other immunostimulating anti-tumor drugs (interferon, interleukin, thymosin, immunocell therapy, etc.) within 1 month before the first administration;

• 7. Participants who are participating in another clinical study or whose first dose is less than 4 weeks (or 5 half-lives of the investigational drug) since the end (last dose) of the previous clinical study;

• 8. Evidence of past or current pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiological pneumonia, drug-induced pneumonia, and severe impairment of lung function;

• 9. Major surgery, open biopsy, or significant trauma were performed within 28 days prior to enrollment;

• 10. Known history of allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation;

• 11. Pregnant or lactating women; A fertile patient who is unwilling or unable to take effective contraceptive measures;

• 12. Known allergic reactions, hypersensitivities, or intolerances to study drugs;

• 13. There are other circumstances in which the investigator considers it inappropriate to participate in the study.

Intervention

Drug:
• Adebrelimab
This product is administered by intravenously guttae. The recommended dose of subcutaneous injection is 20mg/kg, administered every 3 Weeks (Q3W).

Radiation:
• radical chemoradiotherapy
The total dose of radiotherapy was 60 Gy ± 10% (54 Gy - 66 Gy). The minimum technical standard for radiotherapy is the three dimensional conformal radiotherapy (3D-CRT) planned by CT.

Drug:
