Blood microRNA markers to predict response to immunotherapy plus chemotherapy in extensive-stage small cell lung cancer

Small Extracellular Vesicle miRNAs as Predictive Biomarkers for Immunochemotherapy Efficacy in Extensive-stage Small Cell Lung Cancer

Observational Shanghai Chest Hospital of Shanghai Jiao Tong University · NCT07070011

This project will test whether small extracellular vesicle microRNAs in blood can predict which patients with extensive-stage small cell lung cancer will respond to first-line immunotherapy combined with chemotherapy.

What this trial studies

A prospective observational cohort at Shanghai Chest Hospital will enroll treatment-naïve patients with extensive-stage small cell lung cancer who are starting first-line immunochemotherapy (EP/EC plus immune checkpoint inhibitors). Pretreatment serum will be collected and small extracellular vesicle microRNAs (sEV miRNAs) will be sequenced and compared between patients who respond and those who do not. Differential expression analysis will be used to identify miRNA signatures associated with treatment response. Identified signatures could serve as noninvasive liquid biopsy biomarkers to help personalize treatment decisions in ES-SCLC.

Who should consider this trial

Good fit: Ideal candidates are treatment-naïve adults with extensive-stage small cell lung cancer, ECOG 0–1, who are about to start first-line immunotherapy plus chemotherapy and can provide blood samples and clinical follow-up.

Not a fit: Patients with prior chemotherapy or immunotherapy, ECOG >1, incomplete clinical/sample data, or those unable to attend Shanghai Chest Hospital may not benefit from participation or from the biomarker findings.

Why it matters

Potential benefit: If successful, the biomarkers could help doctors predict who is likely to benefit from immunochemotherapy and avoid ineffective treatments.

How similar studies have performed: Similar liquid-biopsy miRNA approaches have shown promising preliminary results in other cancers and small lung-cancer cohorts, but no sEV-miRNA predictors for immunochemotherapy in ES-SCLC are yet widely validated.
