Trial summary

Chronic kidney disease is associated with the accumulation of various metabolites, i.e., uremic retention solutes. Evidence is mounting that the colonic microbiome contributes substantially to these uremic retention solutes. Read more about this study

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 85 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients with known or newly diagnosed chronic slow-transit constipation necessitating treatment with prucalopride (Resolor®, Shire) according to current treatment guidelines

Who may be able to join

  • Age ≥ 18 and ≤ 85 years
  • Chronic slow-transit constipation as defined be 4 criteria:
  • having two or fewer spontaneous complete bowel movements week for a minimum of 6 months
  • having one or more of the following symptoms for at least one-quarter of the time: lumpy/hard stools, a sensation of incomplete evacuation, or straining during defecation.
  • slow transit time as determined by Rx colon transit study ("pellet")
  • without evidence of secondary constipation or primary defecation disorder
Show all 9Show fewer
  • Need of therapy with prucalopride (i.e., inefficacy of dietary changes and laxatives)
  • Follow-up visit possible after 4 weeks of treatment
  • Written informed consent

Who cannot join

  • History or new diagnosis of organic intestinal disease (e.g., inflammatory bowel disease, malignancy)
  • Secondary constipation (drug-induced, endocrine, metabolic or neurological disorders, surgery, known or suspected organic disorders of the large intestine, or megacolon) or primary defecation disorder
  • Use of laxatives two days before start of treatment and during treatment period. If there is no spontaneous bowel movement during 3 consecutive days, rescue treatment with bisacodyl and/or enema is allowed if necessary
  • Presence of significant co-morbidity (uncontrolled heart, liver and lung disease)
  • Pregnancy
  • Chronic kidney disease, i.e., estimated glomerular filtration rate (MDRD) < 60 ml/min/m² or need of dialysis therapy

About this study

Chronic kidney disease is associated with the accumulation of various metabolites, i.e., uremic retention solutes. Evidence is mounting that the colonic microbiome contributes substantially to these uremic retention solutes. Indoxyl sulfate and p-cresyl sulfate are among the most extensively studied gut microbial metabolites, and are associated with cardiovascular disease, chronic kidney disease progression and overall mortality. Colonic transit time is an important determinant of intestinal generation and uptake of bacterial metabolites. However, it is unknown if accelerating the colonic transit time reduces the intestinal generation and uptake of indoxyl sulfate and p-cresyl sulfate. Prucalopride is a selective, high-affinity 5-HT4 receptor agonist with a stimulating effect on colonic motility and transit. It is currently used in treating chronic slow-transit constipation. An observational study will be initiated in non-chronic kidney disease patients with chronic slow-transit constipation necessitating treatment with prucalopride to observe its effect on serum concentrations and intestinal generation of indoxyl sulfate and p-cresyl sulfate.

Questions about this trial

What is this clinical trial studying?

An observational study of Constipation, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.

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 9 inclusion and 6 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: withdrawn, as of the sponsor's last update on 24 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

change in serum concentration of bacterial metabolites (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 24 Apr 2020.
