New GERD drug aims to heal esophagus damage when standard treatments fail

NCT ID NCT05055128

NEW Completed Disease control Sponsor: Cinclus Pharma Holding AB Source: ClinicalTrials.gov ↗

First seen Jul 01, 2026 · Last updated Jul 01, 2026

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.

Active substance

X842

What this could lead to

If successful, X842 could offer a new treatment option for people with severe GERD-related esophagitis that hasn't healed with standard medications.

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.
