Reflux Band in Laryngopharyngeal Reflux

This study seeks to understand if the Reflux Band is an effective treatment for laryngopharyngeal reflux (LPR) in comparison to a sham device. LPR is a syndrome in which acid that is made in the stomach travels up the esophagus and into the throat, causing chronic symptoms including throat clearing, voice hoarseness, sore throat, etc. Participation in the study may or may not benefit you directly, and may result in new knowledge that may help others. Participation in this study involves: 3 - 4 in person visits (2 of which are part of standard of care) ranging from 30 - 45 minutes each and 2 virtual visits, either by phone or video, each 15 minutes. Participants are assigned with a 50/50 chance (similar to a coin flip) via a computer generator to receive the Reflux Band or sham device (a device that will not provide you medical therapy) which they will wear around their neck nightly while sleeping (6+ hours) over a duration of 8 weeks. The Reflux Band, which has been cleared for use by the FDA, applies pressure to the outside of the neck at the cricoid cartilage, at the middle of the neck, and increases the internal pressure of the muscle separating the throat from the esophagus (upper esophageal sphincter). Participants will only wear the band while sleeping at night and remove in the morning upon waking. The in person visits will occur at one of these UCSD La Jolla locations: the Perlman Medical Office Gastroenterology clinic, the Center for Voice and Swallowing, Altman Clinical and Translational Research Institute (ACTRI) Clinic. There is an optional 4 week extension at the end of this study in which the Reflux Band will be refit (if sham) to provide the manufacturer's specified pressure. This portion contains 1 virtual follow up during week 10 and an in person follow up during week 12, at which time study participation will conclude. The most commonly expected risks of the study are skin reaction, discomfort, and difficulty sleeping. These were generally mild and short in duration. No serious risks were observed when the Reflux Band was worn around the neck in previous studies.
