Trial Outcomes & Findings for A Study to Evaluate the Efficacy and Safety of Vonoprazan Compared to Placebo in Participants With Symptomatic Non-Erosive Gastroesophageal Reflux Disease (NCT NCT04799158)

NCT ID: NCT04799158

Last Updated: 2023-01-04

Results Overview

An evaluable heartburn episode was an episode for which study drug was taken and for which the participant completed at least one entry in the heartburn episode diary. For a heartburn episode to be considered completely relieved, a participant must not have taken rescue antacid within 3 hours of taking study drug. For sustained relief, complete relief must have been accompanied by 24 hours without another heartburn episode after taking study drug.

Participant Flow

This study was performed at 54 sites in the United States between 25 March 2021 and 17 January 2022. Of the 1115 participants screened for the study, 458 participants were enrolled into the Run-In Period. Of these participants, 207 participants were randomized to receive study drug in the On-Demand treatment period.

Eligible participants who had symptomatic NERD were initially dosed during an open-label Run-In Period with vonoprazan 20 mg once per day (QD) for 4 weeks. Participants with stable disease (defined by those who had no heartburn on the last 7 consecutive days of the Run-In Period) and were compliant with the electronic diary and study drug were randomized using a 1:1:1:1 allocation ratio to receive either vonoprazan 10 mg, 20 mg, or 40 mg or placebo during the 6-week On-Demand Treatment Period.

PRIMARY outcome

Timeframe: On-Demand Treatment Period: Day 1 to Day 42

Population: Intent-to-Treat (ITT) On-Demand Set: includes all participants in the Safety Run-In set who were randomized and completed at least one heartburn episode diary during the On-Demand Treatment Period.

An evaluable heartburn episode was an episode for which study drug was taken and for which the participant completed at least one entry in the heartburn episode diary. For a heartburn episode to be considered completely relieved, a participant must not have taken rescue antacid within 3 hours of taking study drug. For sustained relief, complete relief must have been accompanied by 24 hours without another heartburn episode after taking study drug.
