Constipation
Dose-Finding Trial of Polyethylene Glycol 3350 Laxative Plus Electrolytes for the Treatment of Constipation (Protocol P07515)
Study Completed
Trial Purpose
The primary objective of the study was to evaluate the proportion of subjects with a bowel movement (BM) without straining or without hard and/or lumpy stool within the first 24 h of treatment for subjects taking 1 of 3 single doses of Polyethylene Glycol (PEG) plus Electrolytes (PEG+E) (13.125 g, 26.25 g, 39.375 g). The doses specified relate to the doses of PEG. Secondary objectives were measured by analysis of a subject diary and self-reported BM data. The secondary objectives included comparisons of PEG+E doses at 24 h for: BM control; relief of gas; relief of bloating; and relief of abdominal discomfort/cramping.
In addition, the proportion of subjects with a BM (without straining and without hard and/or lumpy stool) within the first 24 h of treatment for subjects taking different doses of PEG+E was evaluated for the time to first BM.
Inclusion Criteria
- A willingness to participate in the study and comply with its procedures - Must be ambulatory - Male or female subjects aged 18 years or older who met two or more of the following modified Rome III-based criteria for constipation: (a) straining during at least 25% of defecations; (b) lumpy or hard stools in at least 25% of defecations; (c) sensation of incomplete evacuation for at least 25% of defecation; (d) sensation of anorectal obstruction/blockage for at least 25% of defecations; (e) manual maneuvers to facilitate at least 25% of defecations (eg, digital evacuation, support of the pelvic floor), and (f) fewer than 3 defecations per week - Criteria fulfilled for the last 3 months with symptom onset at least 6 mo prior to diagnosis - Had a self reported or documented history of chronic constipation - Agreed not to use laxatives other than the study treatment from baseline/informed consent to end-of-study - Agreed to maintain a similar diet from the week before Visit 3 to the end-of-study were to be enrolled - Additionally required not to use any treatment known to cause constipation during the study (for subjects enrolled after Amendment 1) - If a female subject, either surgically sterile, 2 years postmenopausal, or using an acceptable method of contraception. Abstinence was not an acceptable method of contraception.

Primary Outcome
- Proportion of subjects with successful BM within 24 h of dosingA successful BM was defined as a BM with no straining or hard/lumpy stoolsTimeframe: Throughout the course of the 24 h treatment period
Secondary Outcome
- Proportion of subjects with successful BM within 12 h of dosingA successful BM was defined as a BM with no straining or hard/lumpy stoolsTimeframe: Throughout the course of the 12 h treatment period
- Time to first successful BMTimeframe: Throughout the course of the 24 h treatment period
- Visual Analogue Scale (VAS) ratings for BM controlThe BM control VAS uses a 100 mm horizontal line with the two ends representing the opposite, extreme limits of the participant's experience of BM control. Participants marked where they felt they resided between the two ends with a vertical line. The distance from the left end of the VAS (0 mm) to the participant's mark was measured and recorded in mm. BM Control ratings ranged on a continuous scale from 0 to 100 mm, where 0 mm=Calm, not urgent and 100 mm= Not able to hold BM, very urgentTimeframe: Throughout the course of the 24 h treatment period
- VAS ratings for gasThe Gas VAS uses a 100 mm horizontal line with the two ends representing opposite, extreme limits of the participant's experience with BM-related gas. Participants marked where they felt they resided between the two ends with a vertical line. The distance from the left end of the VAS (0 mm) to the participant's mark was measured and recorded in mm. Gas ratings ranged on a continuous scale from 0 to 100 mm, where 0 mm=None and 100 mm= SevereTimeframe: Throughout the course of the 24 h treatment period
- VAS ratings for bloatingThe Bloating VAS uses a 100 mm horizontal line with the two ends representing opposite, extreme limits of the participant's experience with BM-related bloating. Participants marked where they felt they resided between the two ends with a vertical line. The distance from the left end of the VAS (0 mm) to the participant's mark was measured and recorded in mm. Bloating ratings ranged on a continuous scale from 0 to 100 mm, where 0 mm=None and 100 mm= SevereTimeframe: Throughout the course of the 24 h treatment period
- VAS ratings for abdominal discomfort/crampingThe Abdominal Discomfort/Cramping VAS uses a 100 mm horizontal line with the two ends representing opposite, extreme limits of the participant's experience with BM-related abdominal discomfort/cramping. Participants marked where they felt they resided between the two ends with a vertical line. The distance from the left end of the VAS (0 mm) to the participant's mark was measured and recorded in mm. Abdominal discomfort/cramping ratings ranged on a continuous scale from 0 to 100 mm, where 0 mm=None and 100 mm= PainfulTimeframe: Throughout the course of the 24 h treatment period
- Subject’s Global Assessment of treatmentAt the End of Study Visit, the study staff asked the participant to rate their global assessment of the study treatment according to the following categories: 0 = not at all effective, 1 = a little bit effective, 2 = moderately effective, 3 = quite a bit effective, 4 = extremely effectiveTimeframe: Throughout the course of the 24 h treatment period
- Number of participants with adverse eventsTimeframe: Between 6 and 16 days
