Trial Outcomes & Findings for Study Comparing Fexuprazan and Esomeprazole in Patients With Gastroesophageal Reflux Disease (NCT NCT07326904)
NCT ID: NCT07326904
Last Updated: 2026-08-24
Results Overview
Symptom relief was assessed using the Gastroesophageal Reflux Disease Questionnaire (GERD-Q). The GERD-Q total score ranges from a minimum of 0 to a maximum of 18, where higher scores indicate a worse outcome (greater severity and higher likelihood of GERD). The primary outcome was defined as the proportion of participants with a GERD-Q total score \<8 at Week 4, indicating adequate relief of GERD symptoms.

Participant Flow
Participants were recruited at three hospital-based outpatient clinics in Indonesia (University of Indonesia Hospital, Islam Cempaka Putih Hospital, and Menteng Mitra Afia Hospital). Recruitment began on 23 September 2024 following institutional review board approval. The last participant was enrolled on 10 October 2024. Eligible adult patients with gastroesophageal reflux disease were identified during routine clinical visits and screened according to protocol-defined criteria.
After enrollment and informed consent, participants underwent a screening and washout period of up to 2 weeks, during which prohibited acid-suppressive or concomitant medications were discontinued. Eligibility was reassessed prior to randomization, and participants who did not meet protocol-defined inclusion or exclusion criteria or withdrew consent were not assigned to a treatment arm.

Timeframe: From first dose until achievement of complete response, up to 8 weeksPopulation: Time-to-event analysis was performed using the Full Analysis Set (FAS), which included all randomized participants who received at least one dose of study drug and had post-baseline symptom diary data.
Complete response was defined as the absence of heartburn and/or acid regurgitation symptoms for 7 consecutive days based on patient diaries. Time to complete response was measured in days from the first dose to the first day of the 7-day symptom-free period. Analysis included all subjects using time-to-event methods.

OTHER_PRE_SPECIFIED outcome
Timeframe: Up to 8 weeksPopulation: The analysis was performed using a subset of the Full Analysis Set (FAS), specifically including only those randomized participants who presented with chronic cough symptoms at baseline and had at least one post-baseline assessment.
The number of participants who experienced relief from chronic cough symptoms during predefined periods after initiation of study treatment, based on participant diary assessments. Note: The "Baseline" rows report the number of participants who indicated they experienced the symptom of chronic cough at baseline, while all post-baseline time points report the number of participants that experienced symptom relief.
