New GERD drug aims to heal esophagus damage when standard treatments fail
NCT ID NCT05055128
First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study tests an experimental drug called X842 in people with severe erosive esophagitis caused by GERD (chronic acid reflux). Participants have either severe esophagus damage (grades C or D) or milder damage that hasn't healed after 8 weeks of standard treatment. The trial compares X842 with the common medication lansoprazole to see which better heals the esophagus after 4 weeks, and tracks symptoms during a follow-up period. The goal is to find the right dose for future larger studies.

- What could go wrong
- This is an early phase 2 dose-finding study, so results may not confirm effectiveness. Side effects are still being evaluated, and the drug may not outperform existing treatments.
