COVID-19 | Device: Vielight RX Plus | Not Applicable |
This study is conducted entirely online. At no point will study staff be in direct contact with participants. The study will be managed by an independent clinical research organization (CRO), supporting a Qualified Investigator (QI). Vielight Inc will supply the RX Plus devices free of charge and will sponsor the study.
Potential participants will be prompted to complete an online screening form if they are interested in participating. During the screening, the potential participant will be asked to upload a copy of their positive COVID-19 infection confirmation report and a valid ID. If the potential subject qualifies for the study, by statisfying all inclusion and exclusion criteria, the potential participant will then be prompted to complete an electronic informed consent form (ICF) via the electronic data collection (EDC) platform and will be enrolled into the study.
This is a 30-day, prospective, randomized study, with no blinding. 280 participants will be randomized into two groups: Group 1: Standard of Care; Group 2: Standard of Care + Vielight RX Plus treatment. In Group 2, the Vielight RX Plus will be administered for 20 minutes twice a day, separated by at least 6 hours for the first 5 days. For the subsequent 25 days, treatment will be once per day. The Vielight RX Plus will be positioned over the upper most part of the breastbone to stimulate the thymus gland and within one nostril.
During each of the 30-days, participants will be asked to complete a questionnaire to assess respiratory symptom severity, and log a daily dairy as well as oxygen saturation level (using a portable oximeter).
The primary measure is time to overall recovery in days.
