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.

Detailed Description

This was a randomized, single-blind, placebo-controlled study to evaluate the proportion of participants with abnormalities of the oral mucosa detected by visual examination of the oral cavity in the polyethylene glycol (PEG) 3350 group compared with the placebo group. The study was also to evaluate the proportion of participants with abnormalities of the esophageal mucosa detected by endoscopic examination of the esophagus in the PEG 3350 group compared with the placebo group, and to compare the safety and tolerability by evaluation of the proportion of participants with the occurrence of adverse events (AEs) or adverse drug reactions.

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.

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
Number of Participants With Inflammation of the Oral Mucosa
Time Frame: Visit 2 (Day 1) and Visit 3 (Day 17 ± 2 days), up to 19 days after start of treatment
Participants underwent visual examination of the oral muscosa at Visit 2 and Visit 3. Measurements were based on 0-3 Likert Scale Scores: 0 = No inflammation (no erythema, no erosion/ulceration); 1 = Mild inflammation (erythema without erosion/ulceration); 2 = Moderate inflammation (erythema with erosion); 3 = Severe inflammation (erythema with ulceration).
Visit 2 (Day 1) and Visit 3 (Day 17 ± 2 days), up to 19 days after start of treatment
Number of Participants With Inflammation of the Esophageal Mucosa
Time Frame: Visit 2 (Day 1) and Visit 3 (Day 17 ± 2 days), up to 19 days after start of treatment
Participants underwent endoscopic examination of the esophageal mucosa at Visit 2 and Visit 3. Measurements were based on 0-3 Likert Scale Scores: 0 = No inflammation (no erythema, no erosion/ulceration); 1 = Mild inflammation (erythema without erosion/ulceration); 2 = Moderate inflammation (erythema with erosion); 3 = Severe inflammation (erythema with ulceration).

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
