Examining the microbiome in patients with advanced lung cancer receiving immunotherapy

Microbiome in Immunotherapy naïve NSCLC Patients Receiving PD-1/L1 Blockade (MIP_NSCLC)

Observational University of Kansas Medical Center · NCT04636775

This study is testing if the bacteria in the gut can help predict how well a new immunotherapy works for people with advanced lung cancer.

What this trial studies

This observational study aims to investigate the role of the microbiome in predicting the effectiveness of PD-1/PD-L1 blockade therapy in immunotherapy-naïve patients with stage IV non-small cell lung cancer (NSCLC). By analyzing the microbiome, researchers hope to identify potential biomarkers that could indicate treatment response and the likelihood of adverse events. Participants will be receiving single-agent anti-PD-1/PD-L1 therapy, and the study will also explore factors that may modify the microbiome. The findings could lead to personalized treatment strategies for patients with advanced NSCLC.

Who should consider this trial

Good fit: Ideal candidates include immunotherapy-naïve patients with biopsy-proven stage IV or recurrent NSCLC who are set to receive PD-1/PD-L1 blockade therapy.

Not a fit: Patients who have previously received any form of cancer immunotherapy or those with significant psychiatric or social issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help tailor immunotherapy treatments based on individual microbiome profiles, potentially improving patient outcomes.

How similar studies have performed: While the role of the microbiome in cancer treatment is an emerging field, similar studies have shown promising results in other cancers, suggesting potential for success in this approach.
