Detailed Description

The purpose of this study is to evaluate the effect of vonoprazan on sleep disturbance in the participants under maintenance treatment for reflux esophagitis with proton pump inhibitor (PPI) other than vonoprazan after initial treatment. Participants who have been diagnosed as reflux esophagitis based on Los Angeles (LA) Classification Grades A to D, undergoing maintenance treatment with PPI other than vonoprazan after initial treatment, and with Pittsburgh Sleep Quality Index (PSQI) global score >= 6.0 at enrolment (VISIT 1) will be eligible for study entry and will be administered vonoprazan 20 mg once daily for 8 weeks. Planned number of participants is 25. The study period is 9 weeks. The number of visits is 6visits.

Clinical Trial Outcome Measures

Primary Measures

  • Changes From Start of Administration (Week 0) in Pittsburgh Sleep Quality Index (PSQI) Global Score at End of Study
    • Time Frame: Week 0 to End of study (up to Week 8)
    • PSQI is a self-rated questionnaire for sleep quality. It includes 18 items across 7 components; C1: Sleep quality, C2: Sleep latency, C3: Sleep duration, C4: Sleep efficiency, C5: Sleep disturbance, C6: Use of sleep medication, C7: Daytime dysfunction. Each component is scored 0-3 (0 = no difficulty, 3=severe difficulty), and total score ranging from 0 to 21. Higher scores are representing worse sleep quality. Reported data were individual scores for each participant (Participant A to C) since descriptive statistics value was not calculated due to small size population (totally 3 participants).
