Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 70 years
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Age between 18-70 years.
- History of constipation i.e., the patient reported the occurrence of TWO OR MORE of the following criteria for at least 6 months before the selection visit :
- two or fewer spontaneous* bowel movements in a week.
- lumpy (scyballae) and/or hard stools at least a quarter of the stools.
- sensation of incomplete evacuation following at least a quarter of the stools.
- straining at defaecation at least a quarter of the time. *A bowel movement was considered spontaneous if it was not preceded by the intake of a laxative agent within a period of 12 hours. An amendment was made changing this period to 24 hours. Moreover, the amendment stated: "Patients who never opened their bowels spontaneously would be considered constipated and eligible to enter the double-blind phase of the trial, whether or not the above mentioned criteria were met for laxativa/enemas induced stools".

- Constipation causing disability; the patient's occupational, social and recreational activities were governed by his/her constipation and efforts to attain relief.
- Normal electromyographic inhibition pattern of the external anal sphincter during straining (clinical and/or electromyographic and/or manometric evidence is acceptable).
- Absence of organic abnormalities of the colon on barium enema or on total colonoscopic examination. This criterion was amended to: "If complaints of constipation were of recent onset,i.e., had been present for 6 months to 1 year, results of a colonoscopic examination performed within the last 12 months were needed. If complaints of constipation had been present for more than one year, results of an endoscopic examination performed within the past three years were acceptable".
- Poor results with laxative treatment and diet counselling.
- Constipation of a functional, i.e., idiopathic nature.
- Availability of the patient's written informed consent.
- Patient available for follow-up during the trial period as determined in the protocol.
Who cannot join
- Constipation thought to be drug-induced.
- Presence of secondary causes of constipation, for instance: endocrine disorders, metabolic disorders, neurologic disorders.
- Congenital megacolon/megarectum.

- Known or suspected organic disorders of the large bowel, i.e., obstruction, carcinoma or inflammatory bowel disease.
- Active proctological conditions which were thought to be responsible for constipation.
Show all 17Show fewer
- Evidence of a non-relaxing pelvic floor ("anismus") as the main cause of constipation.

About this study
Official title: A Double-Blind Placebo-Controlled Dose-Finding Trial to Evaluate the Efficacy and Safety of R093877 in Patients With Chronic Idiopathic Constipation
The purpose of this study is to determine which dose of prucalopride is safe and effective in patients with chronic idiopathic constipation.
Hypothesis:
Prucalopride 1 and 2 mg are safe and effective for the treatment of chronic idiopathic constipation whereas 0,5 mg is a suboptimal dose.
Read the detailed description
This is a phase II trial with a parallel-group design, consisting of a drug-free run-in phase (phase 1), followed by a placebo controlled double-blind phase (phase 2). Patients will receive either R093877 0.5 mg o.d., 1 mg o.d. or 2 mg o.d. or placebo for a period of 4 weeks.
Phase 1 is a run-in period of 4 weeks duration, during which the bowel habit is documented and the existence of constipation confirmed. At the start of this period all existing laxative medication is withdrawn but patients will be instructed not to change their dietary habits, in particular their fibre intake during the trial. Patients will enter the double-blind phase if constipation has been shown to be present during the run-in period.
If the definition of constipation was not met during the 4 weeks of the run-in period, double-blind treatment will not be started.
Phase 2 is a double-blind, randomized, placebo-controlled phase, in which patients will be treated for 4 weeks with either 0.5 mg, 1 mg or 2 mg of R093877 or placebo given once daily (one capsule is taken before breakfast).
Patients admitted to the double blind treatment period will be randomly allocated to one of the 4 treatment arms.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Prucalopride in people with Constipation, run by Movetis.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 May 2008. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evaluation of the efficacy of prucalopride and to compare the effects of 0.5 mg, 1 mg or 2 mg of R093877 versus placebo (time frame: 4 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00617513, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2008.
