A Multicenter, Randomized, Cohort, Prospective Clinical Study of Adebrelimab Consolidation Therapy for Limited-Stage Small-Cell Lung Cancer (LS-SCLC) Without Progression After Concurrent Chemoradiotherapy

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.
