Trial Outcomes & Findings for Pilot Study To Investigate The Association Between Acid Control And Heartburn Symptoms After Proton Pump Inhibitor Treatment (NCT NCT02708355)

NCT ID: NCT02708355

Last Updated: 2017-04-19

Results Overview

Relief of 24 hour heartburn was defined as a daily diary response of "0" to the question "Over the last 24 hours (yesterday and last night), what was the severity of your most intense episode of heartburn?" on at least 6 of the participant's last 7 consecutive days \[Days 8 - 14\] of treatment allowing for one day with a maximum severity of "2".The response was noted by participants in the diary for last 7 consecutive days \[Day 8 - 14\] on a 3 point scale ranged from 0 to 2 where 0= complete relief and 2= maximum severity. Higher score indicated worse condition/more severity. In this outcome measure, participants with relief of 24 hour heartburn and participants without relief of 24 hour heartburn were reported.

PRIMARY outcome

Timeframe: Day 8 up to Day 14

Population: Per protocol analysis set included all randomized participants who provided valid data for Day -1 PH monitoring, take at least one dose of randomized study medication, complete the 14 day treatment phase, undergo and provide valid data for Day 14 pH monitoring and complete at least 5 days of diary entries in each of Days -7 to -1 and Days 8 to 14.

Relief of 24 hour heartburn was defined as a daily diary response of "0" to the question "Over the last 24 hours (yesterday and last night), what was the severity of your most intense episode of heartburn?" on at least 6 of the participant's last 7 consecutive days \[Days 8 - 14\] of treatment allowing for one day with a maximum severity of "2".The response was noted by participants in the diary for last 7 consecutive days \[Day 8 - 14\] on a 3 point scale ranged from 0 to 2 where 0= complete relief and 2= maximum severity. Higher score indicated worse condition/more severity. In this outcome measure, participants with relief of 24 hour heartburn and participants without relief of 24 hour heartburn were reported.

PRIMARY outcome

Timeframe: Baseline, Day 14

Population: Per protocol analysis set included all randomized participants who provided valid data for Day -1 PH monitoring, take at least one dose of randomized study medication, complete the 14 day treatment phase, undergo and provide valid data for Day 14 pH monitoring and complete at least 5 days of diary entries in each of Days -7 to -1 and Days 8 to 14.

Percentage of time was calculated over the 24 hour period during which intra gastric pH \>4 was observed. Relief of 24 hour heartburn was defined as a daily diary response of "0" to the question "Over the last 24 hours (yesterday and last night), what was the severity of your most intense episode of heartburn?" on at least 6 of the participant's last 7 consecutive days \[Days 8 - 14\] of treatment allowing for one day with a maximum severity of "2".The response was noted by participants in the diary for last 7 consecutive days \[Day 8 - 14\] on a 3 point scale ranged from 0 to 2 where 0= complete relief and 2= maximum severity. Higher score indicated worse condition/more severity. In this outcome, change from baseline at Day 14 in percentage of time over the 24 hour period during which intra gastric pH \>4 was observed, was reported.
