January 30, 2025 updated by: Olly, PBC

A 6-week Randomized, Double-blind, Comparative Clinical Study of the Efficacy of an Oral Product in Subjects With Acid Reflux and/or Abdominal Bloating/Distention and Gastrointestinal Symptoms

This study was a prospective randomized clinical study. There was interventional treatment for a total of 8 weeks including a 2-week washout period. The subjects attended four appointments in the clinic throughout the duration of the study.

Study Primary Objective:

• To assess improvement in bloating symptoms

Study Secondary Objectives:

  • To assess safety and tolerability of the formulation
  • To compare the time taken for perceptual improvement in bloating/distention
  • Enzyme blood assays
  • To assess quality of life indices

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in Digestive Quality of Life Questionnaire (DQLQ) scores
Time Frame: from enrollment to end of study at 8 weeks
To assess changes in scores related to bloating, diarrhea, constipation and heartburn on quality-of-life indicators, comparing active supplement to placebo group
from enrollment to end of study at 8 weeks
Changes in Symptom Severity Score (Diary)
Time Frame: from enrollment to end of study at 8 weeks
Patients filled out the symptoms diary that had questionnaires of bowel habits. Abdominal pain and bloating were rated on a 100-point visual analogue scale with 0=none and 100=severe, comparing active supplement to placebo group
from enrollment to end of study at 8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in Gastrointestinal Short Form Questionnaire (GSFQ) Scores
Time Frame: from enrollment to end of study at 8 weeks
To assess changes in gastrointestinal symptoms comparing active supplement to placebo group
from enrollment to end of study at 8 weeks
Changes in Stool Consistency (Bristol Stool Scale)
Time Frame: from enrollment to end of study at 8 weeks
Daily stool consistency ratings will provide data on changes in bowel health and regularity. Average stool consistency scores will be compared across baseline, active treatment, and placebo phases.
from enrollment to end of study at 8 weeks
