Summary

This phase 2 trial tests a nasal spray called Optate in 24 adults with mild COVID-19. The spray aims to lower virus levels in the nose and improve symptoms like congestion. Participants receive either Optate or a placebo, and researchers measure changes in virus levels and symptom scores one hour and 24 hours after treatment.

What this could mean

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

Active substance

Optate (glycine and alkaline buffer) nasal spray

What this could lead to

If it works, this could provide a simple, at-home nasal spray to lower virus levels and ease symptoms for people with mild COVID-19.

What could go wrong

This is a small, early-phase trial with only 24 participants, so results may not apply broadly. The treatment is tested only for mild cases and may not work for severe illness.
