The MVP Trial: A Randomized Controlled Trial of Mechanism Guided vs PPI Strategy for Laryngopharyngeal Reflux
University of California, San Diego
Summary
The goal of this clinical trial is to learn if a mechanism guided strategy that utilizes a multidisciplinary approach to treat adults patients (age 18-89) with chronic throat symptoms who are undergoing clinical evaluation for laryngopharyngeal reflux (LPR) is more effective than the usual care strategy with proton pump inhibitor (PPI) therapy used in gastroenterology for these patients. The main question it aims to answer is: Will a greater proportion of the mechanism guided strategy participants achieve symptom response in comparison to the usual care strategy participants? If there is a comparison group: Researchers will compare the mechanism guided strategy to usual care strategy to see if treatment response differs between the groups. Participants will be be asked to do the following: * participate in an 8-week blinded study phase where they will be randomized to either 1) Mechanism Guided Strategy or 2) Usual Care Strategy * take an oral capsule daily (omeprazole 40mg or placebo) * come to 3 in-person visits at UC San Diego Health for an intervention visit with a study provider * consider incorporating recommended lifestyle modifications * complete weekly surveys
Description
This research study is being conducted to compare the efficacy between usual care and a novel mechanism guided strategy for adults with chronic throat (laryngeal) symptoms undergoing evaluation for laryngopharyngeal reflux (LPR). Usual care strategy is used clinically and is known to reduce chronic throat symptoms. The mechanism guided strategy is a new treatment that personalizes the application of acid suppression medication and voice therapy to the patient. The mechanism guided strategy is being evaluated for how well it works in patients with these throat symptoms. Participants who are u…

Interventions
- DrugOmeprazole 40 MG
8 week double dose therapy of proton pump inhibitor or placebo.
- BehavioralLaryngeal Recalibration Therapy
LRT utilizes therapies that SLPs standardly utilize (mechanical and cognitive guidance) in combination specifically designed to treat laryngeal symptoms. Each session with the SLP will guide subjects through these therapies. The existing script-based LRT protocol consists of the following: 1) mechanical guidance (laryngeal suppression, voice production, breath coordination), 2) cognitive guidance (identification of thinking patterns, recalibration of thoughts about laryngeal sensations).
- BehavioralGERD Lifestyle Recommendations
This is the typical lifestyle recommendations for GERD used clinically.
