|ClinicalTrials.gov Identifier: NCT00488137|
Recruitment Status : Completed
First Posted : June 19, 2007
Last Update Posted : September 26, 2013
The purpose of this study is to determine whether prucalopride is safe and effective in the treatment of chronic constipation.
Prucalopride 2 mg and 4 mg given once daily for 12 weeks is superior to placebo for the treatment of patients with chronic constipation and is well tolerated in those patients
|Condition or disease||Intervention/treatment||Phase|
|Constipation||Drug: Prucalopride Other: Placebo||Phase 3|
This is a multicentre, Phase III trial with a parallel-group design, consisting of a 2 week drug-free run-in period, followed by a 12-week, double-blind, placebo-controlled treatment period.
During the run-in period, the subject's bowel habit will be documented and the existence of constipation confirmed. At the start of this period, all existing laxative medication will be withdrawn and subjects will be instructed not to change their diet or lifestyle during the trial. Subjects will be allowed to take a laxative (Dulcolax) as a rescue medication throughout the trial, but only if they have not had a bowel movement for three or more consecutive days. No Dulcolax should be taken or enemas used within 48 hours prior to the start of the double-blind treatment (48 hours prior to visit 2) and 48 hours following the start of double-blind treatment (48 hours following visit 2). Subjects will enter the double-blind period if constipation is shown to be present during the run-in period.
If the definition of constipation is not met during the 2-week run-in, the subject will be considered ineligible for the double-blind period and will be discontinued from the study.
During the double-blind, randomised, placebo-controlled period, subjects will be treated for 12 weeks with either 2 mg or 4 mg R108512 or placebo, given once daily before breakfast.
