Summary
This study is a randomized, open-label, multicenter exploratory research aiming to evaluate the efficacy and safety of Adebrelimab in combination with chemotherapy (etoposide and platinum-based therapy) as neoadjuvant treatment for resectable stage I-IIIB (stage IIIB limited to T1-4N1-2M0) small cell lung cancer (SCLC). The study is primarily conducted at Tangdu Hospital of the Fourth Military Medical University. A total of 104 patients with stage IA-IIIB SCLC (stage IIIB limited to T1-4N1-2M0) will be enrolled and randomized 1:1 to receive either Adebrelimab plus chemotherapy or chemotherapy alone. Each patient will undergo 3 cycles of study treatment followed by a 3-4 week break before surgery. Treatment will be discontinued if patients experience disease progression, intolerable drug-related adverse events, withdrawal of informed consent, or other specified conditions during the study. Effectiveness and safety outcomes will be monitored throughout the trial. The primary objective is to evaluate pathological complete response (pCR) with Adebrelimab combination therapy. Secondary objectives include assessing event-free survival (EFS), major pathological response (mPR), objective response rate (ORR), disease-free survival (DFS), and safety.

Interventions
Intervention Description for Treatment Group: This intervention includes Adebrelimab in combination with Etoposide and Platinum-based therapy as neoadjuvant treatment for resectable small cell lung cancer (SCLC). Adebrelimab is administered intravenously at a fixed dose of 1200 mg over 30 minutes on Day 1 of each 3-week cycle, followed by Etoposide at a dose of 100 mg/m2 via intravenous infusion over 30 minutes on Days 1 to 3 of each cycle. Concurrently, Platinum-based therapy (either Cisplatin at AUC5 or Carboplatin at AUC5 or Cisplatin at 100 mg/m2) is administered via intravenous infusion on Day 1 of each cycle. The treatment regimen consists of 3-4 cycles, with a 4-6 week drug-free interval before surgical treatment.
Intervention Description for Control Group: This intervention includes Etoposide in combination with Platinum-based therapy as neoadjuvant treatment for resectable small cell lung cancer (SCLC). Etoposide is administered at a dose of 100 mg/m2 via intravenous infusion over 30 minutes on Days 1 to 3 of each 3-week cycle. Concurrently, Platinum-based therapy (either Cisplatin at AUC5 or Carboplatin at AUC5 or Cisplatin at 100 mg/m2) is administered via intravenous infusion on Day 1 of each cycle. The treatment regimen consists of 3-4 cycles, with a 4-6 week drug-free interval before surgical treatment.
