A Multicenter, Open-label, Randomized, Prospective Clinical Study of Adebrelimab Consolidation Therapy for Limited-Stage Small-Cell Lung Cancer (LS-SCLC) Without Progression After Concurrent Chemoradiotherapy
China200 participantsStarted 2026-07-17
Plain-language summary
This study aims to evaluate the efficacy and safety of adebrelimab consolidation therapy after progression-free response of concurrent chemoradiotherapy in patients with limited-stage small cell lung cancer. This study plans to enroll patients with untreated limited-stage small cell lung cancer who meet the inclusion criteria. The eligible patients will be randomly divided 1:1 into two groups to receive treatment regimens for residual lymph nodes and involved irradiated areas. That is, carboplatin AUC 5, D1 + etoposide 100 mg/m…\^2 on days 1, 2, and 3 + thoracic radiotherapy (residual lymph nodes or involved irradiated areas), with each 3-week cycle. After 4 cycles of concurrent chemoradiotherapy, the non-progressing subjects will continue to receive adebrelimab (1200 mg, IV, Q3W) maintenance therapy.

Inclusion criteria
.Age ≥ 18 and ≤ 75 years, regardless of gender. 2.Histopathologically confirmed, untreated limited-stage small cell lung cancer (LS-SCLC) (stage I-III per AJCC 8th edition, with all lesions encompassed in a tolerable radiation plan).
.Clinically staged T1-2N0, operable LS-SCLC patients who are ineligible for surgery or refuse surgery.
.ECOG performance status 0-1. 5.Expected survival ≥ 3 months. 6.At least one measurable lesion per RECIST 1.1. 7.Pulmonary function: FEV1 \> 70% of predicted value. 8.Adequate hematologic and end-organ function, with laboratory results obtained within 7 days before first study treatment:
. Hematology: Absolute neutrophil count (ANC) ≥ 1.5×10⁹/L without G-CSF support within 14 days before first treatment; lymphocyte count (LC) ≥ 0.5×10⁹/L; platelet count (PLT) ≥ 90×10⁹/L without transfusion, G-CSF, or other hematopoietic stimulants within 14 days before first treatment.
. Hepatic function: Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 × ULN; total bilirubin (TBIL) ≤ 1.5 × ULN (≤3.0 mg/dL for patients with confirmed Gilbert syndrome).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
PFS
Timeframe: From date of the first treatment to the first documented disease progression, assessed up to 18 months
. Renal function: Serum creatinine ≤ 1.5 × ULN or creatinine clearance (CrCl) ≥ 50 mL/min (calculated by Cockcroft-Gault, CKD-EPI, or MDRD equation); urine protein \< 2+ (if urine protein ≥ 2+, 24-hour urine protein must be \< 1 g for eligibility).
. Coagulation: International normalized ratio (INR) ≤ 1.5; activated partial thromboplastin time (APTT) ≤ 1.5 × ULN.
. Echocardiography: Left ventricular ejection fraction (LVEF) ≥ 50%. 9.Sexually active subjects of reproductive potential (non-sterilized) must agree to use at least one medically accepted contraceptive method during study treatment and for 6 months after treatment completion. For females of reproductive potential: serum pregnancy test (HCG) must be negative within 7 days before first dosing.
Exclusion criteria
. Histologically confirmed combined small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC).
. Prior systemic anti-tumor therapy or immune checkpoint inhibitor therapy for SCLC.
. Extensive-stage SCLC.
. Presence of malignant pleural effusion. If aspiratable pleural effusion is present during screening, at least one thoracentesis must be performed to confirm the presence or absence of malignant cells.
. Subjects with known or suspected interstitial lung disease (ILD); other moderate-to-severe pulmonary diseases that may interfere with the detection or management of drug-related pulmonary toxicity and severely impair respiratory function, including but not limited to idiopathic pulmonary fibrosis, organizing pneumonia/bronchiolitis obliterans, etc.
. History of active, known or suspected autoimmune disease, including but not limited to myasthenia gravis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, etc.
