Study for Reflux Patients Not Responding to Medications

This is a clinical trial to evaluate the safety and effectiveness of an investigational drug designed for patients with Gastroesophageal Reflux Disease (GERD) who are still experiencing symptoms while on Proton Pump Inhibitors (PPIs). Participants will be randomized to receive study medication or a placebo while continuing to take daily PPI medication.

What will be asked of you

You will make regular visits to our clinic for about 17 weeks (5 visits total). While in the study, you will be randomized to receive the investigational medication or placebo for up to 8 weeks. You will be able to continue taking your current PPI reflux medication during the study. During your visits, the study staff will perform study-related tests and assessments (e.g. physical exam, blood draw, pregnancy tests and urine screening) to see how you're responding to the study medication. The study also requires completion of questionnaires about your symptoms throughout your participation.
