Brief 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.

Detailed 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.

Study Groups

neoadjuvant: adebrelimab combined with platinum-based chemotherapy

Adebrelimab 20mg/kg combined with platinum-based chemotherapy, q3w, MDT after 3 cycles, if the patient is suitable for surgery, surgery will be performed, and Adebrelimab adjuvant therapy will be performed for 35 cycles after surgery or until the disease recurrence or toxicity is difficult to tolerate as indicated by imaging; If the patient is not eligible for surgery after evaluation,, radical chemoradiotherapy will be performed, followed by Adebrelimab consolidation therapy for 35 cycles or until radiographically indicated disease recurrence or toxicity is difficult to tolerate.

Group Type: EXPERIMENTAL

Adebrelimab

Intervention Type: DRUG

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

radical chemoradiotherapy

Intervention Type: RADIATION

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.

Platinum based chemotherapy

Intervention Type: DRUG

Platinum based chemotherapy: Platinum drug must be one of cisplatin, carboplatin or nedaplatin; The other drug must contain one of the following: etoposide, vinorelbine, vinblastine, pemetrexed, taxanes (e.g., paclitaxel, docetaxel, albumin paclitaxel, paclitaxel liposomes) or gemcitabine (gemcitabine is not permitted in concurrent chemoradiotherapy regimens).

radical chemoradiotherapy and adebrelimab consolidation for 38 cycles

Consolidation therapy with adebrelimab , 20mg/kg, q3w, d1, was started within 1 to 42 days after radical chemoradiotherapy. The infusion time of adebrelimab was 60 minutes or more, and the treatment lasted for 38 consecutive cycles or until the disease recurred or the toxic reaction was difficult to tolerate as indicated by imaging.

Eligibility Criteria

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:
