Frequently Asked Questions (FAQs)

How does the use of UVA light effect the body’s natural cells?

Think about going out into the sun everyday for at least 3 hours with no sunscreen on over a period of 20 years – what do you think the likelihood of developing skin cancer is? It is probably high. Now imagine going out in the sun everyday for only 3 minutes with no sunscreen on over a period of 20 years – the probability of developing skin cancer is greatly reduced.

These examples represent a conversation about dose, which is the measure of the total light energy delivered over a certain period of time. UVLrx Therapeutics™ takes great care to ensure that the dose of light delivered by the Model UVL1500 UVLrx Treatment System™ falls well within the safety range established within the peer-reviewed clinical literature. However, we must also discuss the UV light spectrum to appropriately answer this question. The UV light spectrum is divided into three categories: UVA, UVB, and UVC. The UVA wavelength, compared with the UVB and UVC wavelengths, is 1000-fold less likely to cause a genetic abnormality. The UVA wavelength has a more specific effect on pathogens than our own cells. Additionally, UVA light causes the production of reactive oxygen species, which represents its primary antimicrobial mechanism. Human cells have an extensive system to effectively remove reactive oxygen species, known as antioxidant pathways. These antioxidant pathways quickly remove the slight increase of reactive oxygen species generated by UVA. We leverage clinical data to further corroborate the safety and efficacy of administering a UVA wavelength. Overall, we use dose and wavelength to determine patient safety, which has earned the Model UVL1500 UVLrx Treatment System™ a non-significant risk determination in the United States.

What size catheter does the UVLrx Dry Light Adapter™ integrate with?

At this time, the UVLrx Dry Light Adapter™ is only able to integrate into a 20-gauge x 1” peripheral intravascular catheter. Any other catheter size may absorb too much of the light, diminishing the treatment’s effectiveness.

Who can get the treatment?

Only a certified UVLrx™ provider can answer this question.

How long is a treatment?

Treatments are 60 minutes in length. They are divided into two thirty-minute phases. Each phase administers a specific combination of wavelengths to maximize the desired clinical effect. All wavelengths are administered concurrently and the device requires no adjustment as the patient shifts from phase 1 to phase 2 of the entire 60-minute treatment.

How many total treatments would I need to undergo?

The total number of treatments depends on the type of condition your UVLrx™ provider will be treating. Additionally, overall treatment count will be determined based on numerous factors that only your UVLrx™ provider is able to determine. However, the total treatment number recommended by your UVLrx™ provider will be based on the accumulation of clinical data and experience obtained by our global network of clinical advisors.
