This 12 week biomarker targeted double blind randomized controlled trial (RCT) will enroll subjects with salivary pepsin positive laryngopharyngeal reflux (LPR) to assess efficacy of the external upper esophageal sphincter (UES) compression device, also known as the Reflux Band. Subjects will be randomized to one of two arms: control or experimental. Following the 8 week intervention period subjects in both arms will continue in a 4 week unblinded period. The primary hypothesis is that a significantly higher proportion of subjects in the experimental arm will meet the primary endpoint for symptom response, compared to subjects in the control arm.
