  • 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 subject 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 a week,
  • lumpy (scyballae) and/or hard stools at least ¼ of the stools,
  • sensation of incomplete evacuation after at least ¼ of the stools,
  • straining at defaecation at least ¼ of the time. *The above criteria were only applicable for spontaneous bowel movements i.e., not preceded within a 24-hour period by the intake of a laxative agent.

  • Constipation being severe and causing disability; the subject's occupational, social and recreational activities were governed by his/her constipation and efforts to attain relief;

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 constipation.

Hypothesis:

Prucalopride 1 and 2 mg bid are safe and effective for the treatment of chronic 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 b.i.d., 1 mg b.i.d. or 2 mg b.i.d. or placebo for a period of 12 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 At the start of this period all existing laxative medication is withdrawn and patients will be instructed not to change their dietary habits, in particular their fiber intake during the trial.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, the patient will be considered ineligible for the double-blind period.

Phase 2 is a double-blind, randomized, placebo-controlled phase, in which patients will be treated for 12 weeks with either 0.5 mg, 1 mg or 2 mg of R093877 or placebo given twice daily (one capsule is taken before breakfast and one is to be taken before the evening meal).

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 12 inclusion and 21 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 and to compare the effects of 0.5 mg, 1 mg or 2 mg of R093877 versus placebo (time frame: 12 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 NCT00631813, 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.
