Could longer or stronger antivirals beat COVID in vulnerable patients?

NCT ID NCT05587894

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at whether giving a longer course (10 days instead of 5) or adding another antiviral (remdesivir) to the standard Paxlovid treatment helps immunocompromised people clear COVID-19 faster. About 256 adults with mild or no symptoms will be randomly assigned to different treatment plans. The main goal is to see if the virus is gone by day 10.

What this could mean

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

Active substance

Paxlovid (nirmatrelvir/ritonavir) and remdesivir

What this could lead to

If successful, this could show that a longer course or combination of antivirals helps immunocompromised people clear COVID-19 faster and avoid severe illness.

What could go wrong

This is a Phase 2 trial with only 256 participants, so results are preliminary. The added drugs may cause more side effects or not improve outcomes significantly.
