Oxygen bubbles could tame IBD flares without drugs
NCT ID NCT06944873
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at a new way to control inflammation during flare-ups of Crohn's disease and ulcerative colitis. Researchers will take blood samples from 30 adults with severe IBD and test whether oxygen microbubbles can reprogram immune cells (monocytes) to produce fewer inflammatory signals. The goal is to find a drug-free approach that could one day offer an alternative to current treatments.
