Study summary

The purpose of this study is to investigate the effects of a widely available over the counter supplement marketed for heartburn symptoms on symptoms and health-related quality of life in patients with gastroesophageal reflux disease (GERD). This study is designed as a pilot trial to assess safety and feasibility and to provide preliminary estimates of effect sizes.

What researchers measure

Primary outcomes

  1. Safety - Number of Participants Experiencing a Serious Adverse Event

    Serious adverse events (as defined by the FDA) are events that are potentially life-threatening or result in death, hospitalization, an emergency room visit, disability or permanent damage, a congenital abnormality, require intervention to prevent permanent impairment, or seriously jeopardizes a patient's health.

    Time frame: 2 week follow-up

Secondary outcomes

  1. Number of Subjects With a 50% or Greater Decrease in GERD Symptom Severity

    Average daily GERD symptom severity during the last 7 days of the study was compared to average daily GERD symptom severity at baseline using daily study diary entries. GERD symptom severity for each day was based on the sum of scores assessing the severity of daytime heartburn, nighttime heartburn, and acid reflux each on a 0-4 point scale (none, mild, moderate, severe, very severe). Higher scores signify worse symptoms. The number of subjects with a 50% or greater decrease in GERD symptom severity from baseline to end of study in each group was calculated.

    Time frame: Second week of the trial compared to pre-trial baseline

  2. GERD Health-Related Quality of Life at Follow-up

    The GERD Health-Related Quality of Life (GERD-HRQL) scale is a validated instrument assessing GERD-specific health-related quality of life using 10 questions, each on a 0-5 point scale. Scale range is 0-50 with higher numbers signifying worse quality of life.

    Time frame: Two weeks

The record gives a start of Jun 2013, a primary completion of Apr 2014 and a completion of Apr 2014. It does not say whether these dates are actual or estimated.

Results were first posted in Mar 2017, 2 years 11 months after primary completion.

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 Mar 29, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
