NCT ID NCT04393038

First seen Jan 04, 2026 · Last updated May 03, 2026 · Updated 16 times

Summary

This study tested an experimental drug called ABX464 in 509 adults aged 65 or older, or aged 18+ with risk factors like obesity or diabetes, who had COVID-19. The goal was to see if the drug could reduce inflammation and prevent severe breathing failure. However, the study was stopped early because an interim analysis showed the drug was not working better than a placebo.
