Adebrelimab Combine With Etoposide Capsules in ES-SCLC Maintenance Therapy

This prospective clinical study aims to evaluate and observe the efficacy and safety of adebrelimab combined with etoposide capsules in maintenance therapy for extensive-stage small cell lung cancer using a single-arm trial design. The study is planned to be conducted in Shaanxi Province, China, with an initial target enrollment of 32 patients. The study commenced in August 2025, and recruitment is expected to conclude around December 2026, with the trial anticipated to end by December 2027. Assuming no occurrences such as withdrawal of informed consent by subjects, intolerable adverse drug reactions, or investigator-assessed unsuitability for further participation, each participant's estimated duration of study treatment will continue until radiographically confirmed tumor progression.
