Conditions

Reflux Esophagitis

Brief summary

The purpose of this study is to exploratorily evaluate the effect of vonoprazan 20 mg on sleep disturbance of patients with reflux esophagitis, who have heartburn and/or regurgitation and ≥ 6.0 in the Pittsburgh Sleep Quality Index (PSQI) global score despite the maintenance treatment with PPI other than vonoprazan.

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.

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).

Changes From Start of Administration (Week 0) in PSQI Global Score at Week 4

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 participants (Participant A to C) since descriptive statistics value was not calculated due to small size population (totally 3 participants).

Time frame: From Week 0 to Week 4

Population: Full Analysis Set (FAS): All participants who received at least 1 dose of the study drug for the treatment period.

Percent Changes From Start of Administration (Week 0) in Actigraph-Measured Sleep Efficiency at Week 4, and End of Study

Actigraph is a small device usually that records the activity level of the body by sensing physical movement and that is used especially to measure the amount and quality of sleep. Mean value from the past 7 days at each time point was used for calculation. Reported data were individual values for each participants (Participant A to C) since descriptive statistics value was not calculated due to small size population (totally 3 participants).

Time frame: Week 4 and End of study (up to Week 8)

Population: Full Analysis Set (FAS): All participants who received at least 1 dose of the study drug for the treatment period.
