Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
