Summary

This phase 2 trial tested whether adding aprepitant, a drug usually used for nausea, to standard care could help hospitalized COVID-19 patients recover faster. The study planned to enroll adults recently admitted to the hospital with COVID-19 and signs of lung involvement. However, the trial was terminated early after enrolling only 27 participants, so the results are limited.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
aprepitant injectable emulsion
What this could lead to
If it works, this could point toward a new treatment to help hospitalized COVID-19 patients recover faster and avoid severe outcomes.
What could go wrong
This was a small, early-phase trial that was terminated before completion, so results are limited and may not be reliable. Aprepitant is not a proven treatment for COVID-19.
