What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study

Summary

This study looks at 48 adults with advanced lung cancer who are about to start immunotherapy. Researchers will collect samples from the lungs, stool, and blood before and after treatment to see if certain bacteria are linked to better outcomes. The goal is to understand why some people respond well to immunotherapy while others do not.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors predict which lung cancer patients will benefit from immunotherapy, leading to more personalized treatment plans.
What could go wrong
This is an early observational study with only 48 participants, so results may not apply to all patients. It does not test a new treatment, so no direct benefit to participants.

Inclusion Criteria: * Adult patients with a diagnosis of advanced stage unresectable Non-Small Cell Lung Cancer and indication for PD-1 blockade treatment (either as monotherapy or combined with chemotherapy) Exclusion Criteria: * Antibiotic, steroid, or chemotherapy received within the prior month since these are possible confounders that may impact the microbiome and the host immunity. * Brain metastasis (as evaluated by MRI obtained as part of standard of care staging evaluation) * FEV1\<50% predicted * Cardiovascular disease (defined as abnormal EKG, known or suspected coronary artery disease or congestive heart failure) * Renal disease * Coagulopathy * Liver disease
