What researchers measure

Primary outcomes

  1. Percentage of days without nighttime heartburn during the 2-week dosing period

    Percentage of days without nighttime heartburn = Number of days without nighttime heartburn symptoms during the dosing period / Number of days when nighttime heartburn was assessed x 100

    Time frame: 2 weeks

Secondary outcomes

  1. Time to first nighttime hearturn-free interval(days)

    Number of days to reach the first day without symptoms of nighttime heartburn after the administration of investigational drug

    Time frame: 2 weeks

  2. Percentage of days without daytime heartburn during the 2-week dosing period

    Percentage of days without daytime heartburn = Number of days without daytime heartburn symptoms during the dosing period / Number of days when daytime heartburn was assessed x 100

    Time frame: 2 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2023 (actual). Primary completion is estimated for Dec 2024, 21 months after the start.

Of 30 phase 4 interventional studies under Gastroesophageal Reflux, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 53. This study's planned 21 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 3, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
