Overview
This prospective, observational cohort study aims to explore the influence of obstructive sleep apnea(OSA) on the efficacy of PD-1-based immunotherapy in patients with non-small cell lung cancer(NSCLC). Patients who had no prior treatment for advanced NSCLC and are intended to receive PD-1/PD-L1 antibody will be recruited. According to sleep monitor results, participants will be divided into Group NSCLC and Group OSA+NSCLC. Primary outcome is the objective remission rate(ORR).
Description
This is a single-center, prospective, observational cohort study. Patients who had no prior treatment for advanced NSCLC and are intended to receive PD-1/PD-L1 antibody will be recruited and followed for 4 years. According to the baseline sleep monitor results, participants will be divided into Group NSCLC(AHI<15), and Group OSA+NSCLC(AHIā„15), and then explore the influence of obstructive sleep apnea on the efficacy of PD-1-based immunotherapy. The baseline level of white blood cell count (WBC); absolute neutrophil count (ANC); absolute lymphocyte count (ALC); ANC to ALC (ANC:ALC) ratio; interleukin 6 (IL-6); C-reactive Protein (CRP) in peripheral blood, lymphocytes classification and count by flow cytometry, and gut microbiome analysis by quantitative metagenomics will also be measured to further search for the possible mechanisms. Primary outcome is the objective remission rate (ORR), secondary outcomes include overall survival (OS) and progression free survival (PFS).
The study protocol has been approved by the Peking University First Hospital Institutional Review Board (IRB). Any protocol modifications will be submitted for the IRB review and approval.
