About this study

Official title: Impact of Low Protein Diet Supplemented With Ketoanalogues on Uremic Toxins Production and Glucose Metabolism in Chronic Kidney Disease

Chronic kidney disease (CKD) is associated with accumulation of uremic toxins like p-cresyl sulfate and indoxyl sulfate that are associated of cardiovascular complication and perturbation of glucose metabolism. These toxins are produced by fermentation of protein by intestinal microbiota but the role of low protein diet and ketoanalogue supplementation on uremic toxins production and microbiota composition are unknown. Low protein diet supplemented with ketoanalogues is recommended inCKD patients to prevent progression of renal disease. The aim of this study is to determine the impact of uremic toxins concentration, microbiota composition and gut hormone involved in carbohydrate metabolism ( GLP-1, FGF19, bile acids) with low protein diet supplemented with ketoanalogues.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing keto-analogs in people with Renal Failure, run by Hospices Civils de Lyon at 1 site in France.

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 8 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 9 Jul 2021. 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 France. 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.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Laetitia KOPPE, MD (+33 4 72 67 87 15 ext. +33, Laetitia.koppe@chu-lyon.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Indoxyl Sulfate Plasmatic concentration (time frame: After 3 months of diet). 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 9 Jul 2021.
