Tiny bubbles of hydrogen and oxygen to be infused into humans for first time
NCT ID NCT07357909
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This first-in-human study tests whether hydrogen-oxygen ultrafine bubbles can be safely infused into the bloodstream of healthy adults. About 40 participants will receive two infusions one week apart, with doses increasing in later groups. The study only checks for side effects and does not aim to treat any disease.
