ClinConnect Summary

This clinical trial is studying a new treatment called MHS-1031 to see if it can help people with gastroesophageal reflux disease (GERD) who still experience heartburn symptoms despite taking common medications known as proton pump inhibitors (PPIs). The goal is to find out if MHS-1031 can increase the number of days patients are free from heartburn. The study is being conducted at multiple locations and will include participants aged 18 to 75 who have been experiencing heartburn for at least three months and have been using PPIs for at least four weeks with some symptom improvement.

To participate, individuals must be able to complete online questionnaires each night and have internet access. Those interested will need to sign consent forms and meet specific health criteria, such as being on stable medication for other conditions and maintaining a consistent diet and exercise routine. Participants can expect to be randomly assigned to receive either MHS-1031 or a placebo (a treatment that looks like the real drug but contains no active ingredients) for a period, and they will be monitored closely throughout the study. It's important to note that certain medical conditions and recent treatments may exclude someone from participating to ensure their safety and the accuracy of the study results.
