Is this trial a fit for you?

Likely a good fit

Adults aged 19–75 with acute or chronic gastritis who are scheduled to start Fexuclue (fexuprazan) and have at least one symptom requiring treatment are the intended participants.

Probably not a fit

People with contraindications to Fexuclue, those outside the 19–75 age range, or those whose symptoms do not respond to the medication are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this observational, real-world study, adults prescribed Fexuclue (fexuprazan) will complete electronic patient-reported outcome (e-PRO) surveys on gastrointestinal symptoms before starting the medication and again 2 to 4 weeks after administration. A separate e-PRO will collect patient-reported convenience of the medication at about 2 weeks (up to 4 weeks). Investigators will also record their clinical judgment of overall improvement in the case report form (CRF). Eligibility is limited to adults aged 19–75 who are scheduled to receive Fexuclue according to approved indications, and no experimental procedures beyond routine care are imposed.

Why it matters

Potential benefit: If successful, this could show that Fexuclue improves patient-reported gastritis symptoms and is convenient to use in routine clinical practice.

How similar studies have gone: Other potassium-competitive acid blockers like vonoprazan have shown symptom and mucosal healing benefits in acid-related disorders, but real-world patient-reported outcome data specific to fexuprazan remain limited.
