CapScan: an ingestible capsule that collects gut microbes and metabolites
Development and clinical evaluation of the CapScan gastrointestinal sampling device for metabolomics monitoring
An ingestible capsule that collects small samples from different parts of the gut so doctors can learn about gut microbes and how they process food, tested in healthy volunteers and people with gut conditions.

What this research studies
This project will build and bench-test the CapScan capsule and check that it is safe, reproducible, and specific to different gut regions. You would swallow the capsule so it can collect tiny samples from parts of your gastrointestinal tract, and researchers will analyze microbes and metabolic by-products from those samples. The team will first test safety and regional specificity in healthy volunteers, then use CapScan to see how proton pump inhibitors affect the microbiome and to compare regions of the gut in patients with small intestinal bacterial overgrowth (SIBO) before and after antibiotics. The investigators hope CapScan could eventually be used routinely to monitor gut health like a blood test.
Who could benefit from this research
Good fit: Ideal candidates include healthy volunteers for the safety phase, people taking proton pump inhibitors (PPIs), and patients diagnosed with small intestinal bacterial overgrowth (SIBO) who can safely swallow a capsule.
Not a fit: People who cannot safely swallow capsules or who have intestinal strictures, obstructions, or other contraindications to ingestible devices may not be eligible or benefit.
Why it matters
Potential benefit: If successful, CapScan could allow clinicians to monitor gut microbiome and metabolic changes with a simple, noninvasive capsule.
How similar studies have performed: Capsule endoscopy and some ingestible sampling devices exist, but using a capsule specifically for regional microbiome and metabolome monitoring in clinical care is relatively new.
