New drug fails to show benefit in severe COVID-19 pneumonia trial
NCT ID NCT05254990
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding reparixin to standard care could prevent death or the need for a breathing machine in 414 hospitalized adults with COVID-19 or other pneumonia. The trial was stopped early. Researchers compared reparixin to a placebo to see if it reduced severe outcomes like needing a ventilator or dying within 28 days.
