About this study

Official title: A Double-Blind, Placebo-Controlled Trial to Evaluate the Efficacy, Safety and Quality-of-Life of R108512 Tablets in Elderly Subjects With Chronic Constipation

The purpose of this study is to determine whether prucalopride is safe and effective in the treatment of chronic constipation in elderly patients.

Hypothesis:

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

Read the detailed description

This is a multicentre, randomised, Phase III trial with a parallel-group design, consisting of a 2 week drug-free run-in period, followed by a 4-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 At the start of this period, all existing laxative medication will be withdrawn and subjects will be instructed not to change their diet or lifestyle during the trial.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. Subjects will enter the double-blind period if constipation is shown to be present during the run-in period. Patients will be randomly allocated to one of the 4 treatment arms: 1 mg, 2 mg, 4 mg of R108512 or placebo, with a 25% chance to each treatment group.

During the double-blind period, subjects will be treated for 4 weeks with either 1 mg, 2 mg or 4 mg R108512 or placebo, given once daily before breakfast.

Questions about this trial

What is this clinical trial studying?

A Phase 3 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 6 inclusion and 10 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Proportion of subjects with an average of 3 or more SCBM per week (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 NCT00487422, 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.
