JustLight has launched clinical trials to evaluate its Sunflower Rx medical device, which provides smart photobiomodulation (PBM) treatment for Alzheimer’s disease.  

PBM is the medicinal use of red or near-infrared light for repairing, energising and healing cells in the body without any side effects.

The device uses specific wavelengths of near-infrared light to bypass the skull and be directly absorbed by the brain.

It uses high-efficiency LEDs with four wavelengths for precision dosing according to scientific references.

Developed in partnership with Kaiyan Medical and Light Tree Ventures, the technology aims to be the first US Food and Drug Administration (FDA)-approved safe and effective medical device for Alzheimer’s in the world.

JustLight founder Peter Forhan said: “Our patent-pending technology automatically adjusts the LED Light output to replicate clinical parameters, delivering precise and effective photobiomodulation treatment in the comfort of one’s home.

“We aim to solve the $321bn Alzheimer’s crisis and revolutionise our health care system through universal access to photobiomodulation.”

The company has been using seed funding of more than $2.8m, obtained from companies that included Asahi Kasei, to prepare for clinical trials on Sunflower Rx.

With Nexcare Health Systems, JustLight has started pilot studies on the device to better understand the possible clinical outcomes of Alzheimer’s-based dementia patients using Sunflower Rx.

JustLight chief scientific officer Dr Janet Price said: “After six weeks of continuous Sunflower use, Nexcare participants reported positive experiences and showed improved or stable cognition scores based on standard clinical measures.

“The majority of mild-moderate individuals experienced an improvement in standardised cognitive test scores in one month of daily use.”

Improved mood and better communication with staff were also observed in participants.

The company is now moving forward with additional products such as the Violet far UV-C hand-cleaning device, which is used to kill germs.

A clinical study on this device is currently underway at the University of Michigan, US.
