Trial summary

Cardiovascular related disease is the main cause of death in patients with kidney disease, and "oxidative stress" is thought to be a major contributor by promoting thickening of the heart muscle and stiffening of the arteries. Read more about this study

About this study

Cardiovascular related disease is the main cause of death in patients with kidney disease, and "oxidative stress" is thought to be a major contributor by promoting thickening of the heart muscle and stiffening of the arteries. Allopurinol, a drug used safely in the treatment of gout for many years, has been found to dramatically reduce "oxidative stress". It is therefore hoped that it also reduce the thickened heart muscle and stiffened arteries. If it did, it is likely to reduce the appallingly high cardiac death rate in this group of kidney disease patients.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Allopurinol in people with Kidney Disease and Left Ventricular Hypertrophy, run by A. D. Struthers at 1 site in United Kingdom.

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 2 inclusion and 9 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 3 Nov 2016. 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 United Kingdom. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Primary objective is to see if Allopurinol reduces left ventricular hypertrophy (LVH) in this group of CKD patients (time frame: 9 months). 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 3 Nov 2016.
