NCT ID NCT04305457
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether breathing in nitric oxide gas could keep mild-to-moderate COVID-19 from becoming severe. Researchers enrolled 62 hospitalized adults who were breathing on their own. The goal was to see if the gas reduced the need for a breathing tube. The trial was stopped early, so results are limited.
