About this study

Official title: Saving Residual Renal Function Among Haemodialysis Patients Receiving Irbesartan - a Double Blind Randomised Study

Angiotensin II receptor blockers (ARB) are known to preserve kidney function among patients with kidney diseases and reduced renal function, but not among haemodialysis patients.

Haemodialysis patients often lose residual renal function after initiating dialysis leading to worsened quality of life, increased morbidity and mortality.

In this study an ARB is investigated in a double blind, randomised, parallel group, placebo controlled manner to see, if this ARB can save residual renal function among haemodialysis patients. Potential cardiovascular benefits of the treatment are also addressed.

Read the detailed description

Haemodialysis patients often lose residual renal function rather quickly after initiation of dialysis - average loss is 30 % per year. Loss of residual kidney function leads to deteriorating quality of life, more morbidity and a higher mortality. Many causes to this has been identified, but no one has - to my knowledge - addressed saving of residual renal function among haemodialysis patients so far.

Hypothesis: Irbesartan can reduce loss of residual kidney function among haemodialysis patients and left ventricular hypertrophy and arterial stiffness is less pronounced after 1 year of treatment.

Methods: 80 patients are randomised to receive either irbesartan, an angiotensin II receptor blocker (ARB), or placebo for 1 year. Residual renal function will be estimated before and one-two weeks after initiating project medicine, in order to estimate the acute effect of ARB on residual renal function in this study population. Thereafter, glomerular filtration rate (GFR) and urine volume will be determined after 3, 6, 9 and 12 months giving a regression line for each patient. 8 dialysis units will be recruiting patients.

Investigations:

  • creatinine-urea-clearance by 24h urine collection
  • applanation tonometry
  • cardiac output
  • echocardiography
  • QoL questionnaire
  • endocrinological and cardiovascular markers in blood and urine

Perspectives: It is well-known that ceased urine production has a tremendous negative effect on the quality of life of haemodialysis patients. Lately it was shown that residual renal function has greater impact than dialysis dose on morbidity as well as mortality. Among peritoneal dialysis patients in Asia an angiotensin-converting enzyme inhibitors (ACEI) or an ARB saved residual renal function, but preservation of renal function has not been addressed in haemodialysis patients, and ACEI or ARB are only prescribed to roughly 15 % of these.

If this study confirms our hypothesis the growing population of haemodialysis patients should be offered irbesartan.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Irbesartan in people with Kidney Failure, Chronic, run by University of Aarhus at 6 sites in Denmark.

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 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: finished, as of the sponsor's last update on 8 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Denmark. 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 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?

Decrease in loss of residual kidney function. (time frame: 3, 6, 9 and 12 months). 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 NCT00791830, which also lists 3 linked publications.

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 8 Jan 2013.
