Vielight Launches COVID-19 Clinical Trial with Home-Use Device

Yahoo! Finance  online


“We have designed the Vielight RX Plus with specific parameters based on PBM research that are relevant to impacting coronavirus infections. By conducting this study, we seek to prove the hypothesis that the Vielight RX Plus will accelerate recovery and reduce the severity of the viral infection”, said Dr. Lew Lim, Founder and CEO of Vielight Inc. “It’s affordability, comfort and suitability for home-use are important features needed for widespread adoption. We now need to evaluate through this clinical trial, whether it will also be effective.”

Modifying resting-state EEG microstates with pulsed near-infrared transcranial photobiomodulation: a randomized sham-controlled crossover study

Brain Stimulation: Basic, Translational, and Clinical Research in Neuromodulation

2021 Objective: Transcranial Photobiomodulation (tPBM) is a novel noninvasive brain stimulation technique that applies near-infrared (NIR) light and influences cortical oscillation. However, the mechanism and extent of its effects are yet to be understood. In this study, we investigated the effect of active vs. sham tPBM on the temporal dynamics of large-scale brain networks using resting-state EEG microstate. Methods: Twenty healthy volunteers received 20 minutes of active or sham tPBM using 810 nm light-emitting diodes (LEDs), pulsed at 40 Hz with 50% duty cycle, delivered transcranially to the default mode network. 10-minute eyes-closed EEG recordings were collected before and after each stimulation session. The artifact-free resting-state data were used for microstate analysis, focusing on the mean duration, frequency of occurrence, and ratio of time coverage. We used the two-step k-mean clustering method to …

Home-use Photobiomodulation Device Treatment Outcomes for COVID-19


2022 BACKGROUND There is need for non-pharmaceutical treatments for COVID-19. A home-use photobiomodulation (PBM) device was tested as Treatment in a randomized clinical trial. METHODS 294 patients were randomized with equal allocation to Treatment or Standard of Care (Control). 199 qualified for efficacy analyses. The Treatment group self-treated for 20 minutes twice daily, for the first 5 days, and subsequently once daily for 30 days. A validated respiratory questionnaire was used, and patients were monitored remotely. The primary endpoint was the time-to-recovery (3 consecutive days of no sickness) for general sickness. The Kaplan-Meier method and the Cox Proportional Hazards model were primary methods of analyses.

Near-infrared photobiomodulation of living cells, tubulin, and microtubules in vitro

Frontiers in Medical Technology

2022 We report the results of experimental investigations involving photobiomodulation (PBM) of living cells, tubulin, and microtubules in buffer solutions exposed to near-infrared (NIR) light with a wavelength of 810 nm pulsed at a frequency of 10 Hz. In the first group of experiments, we measured changes in the alternating current (AC) ionic conductivity in the 50–100 kHz range of HeLa and U251 cancer cell lines as living cells, exposed to PBM for 60 minutes, and observed increased resistance compared to the control experiments. In the second group of experiments we investigated the stability and polymerization of microtubules under exposure to PBM. The protein buffer solution used was BRB80/PEM. Exposure of TaxolTM-stabilized microtubules (∼ 2 μM tubulin) to the LED at 810 nm, with a power density of 25 mW/cm2 pulsing at 10 Hz for 120 minutes, resulted in gradual disassembly of microtubules observed in fluorescence microscopy images.
