Outcome Measures

Primary Outcomes (2)

  • Number of Participants With Inflammation of the Oral Mucosa

    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

    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).

    Visit 2 (Day 1) and Visit 3 (Day 17 ± 2 days), up to 19 days after start of treatment

Study Arms (2)

PEG 3350

EXPERIMENTAL

Participants will receive a 17 g dose of PEG 3350 solution concentrate in a volume of approximately 30 mL, once a day, for 14 days. Bisacodyl laxative tablets, 5.0 mg, 1 to 3 tablets in a single daily dose, will be provided for use as a rescue medication if a participant has not had a bowel movement for 72 hours after start of treatment.

Criteria for functional constipation must be fulfilled for last 3 months, with symptom onset at least 6 months prior to diagnosis.
  • continuous or recurrent symptoms for at least 3 months of: abdominal pain or discomfort, relieved with defecation, or associated with a change in frequency or consistency of stool, and an irregular pattern of defecation at least 25% of the time with 3 or more of the following: altered stool frequency, altered stool form (hard or loose/watery), altered stool passage (straining or urgency, feeling of incomplete evacuation), passage of mucus, and bloating or abdominal distension
  • agrees to not use laxatives other than study medication for the duration of the study period
  • agrees to not use disallowed concomitant medications for the duration of the study
