NCT ID NCT07610967
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial tests a handheld light device (RD-X19) to see if using it for 5 minutes every other day can prevent upper respiratory infections like COVID-19 and flu. It involves 130 military personnel and their families at a single base. Half will get the real device, half a sham device, and researchers will compare infection rates.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
RD-X19 device (photobiomodulation)
What this could lead to
If it works, this could offer a simple, drug-free way to lower the risk of catching respiratory infections like COVID-19 or flu.
What could go wrong
This is an early trial with only 130 people, all from a specific military base, so results may not apply broadly. The device is still unproven for this purpose.
