Extensive Stage Small Cell Lung Cancer Oligometastasis Adebrelimab Chemotherapy Radiotherapy

ClinConnect Summary

This clinical trial is studying a new treatment for patients with extensive-stage oligometastatic small cell lung cancer (SCLC), a type of lung cancer that has spread to other parts of the body. The treatment combines a medication called adebrelimab with chemotherapy drugs (carboplatin or cisplatin plus etoposide) and radiation therapy. The goal is to see how well this combination works and how safe it is for patients who have not received any previous treatment for their cancer.

To be eligible for the trial, participants need to be between 18 and 75 years old and have a confirmed diagnosis of extensive-stage SCLC with a limited number of metastatic lesions (cancer spread). They should also be in reasonably good health, with an expected survival time of at least three months. Participants will need to provide a tumor sample and will be closely monitored throughout the study. This trial is currently recruiting participants, and it’s important for potential volunteers to discuss with their doctors to understand if they meet the criteria and if this trial is right for them.
