Trial summary

Kidney disease is a fundamental part of medicine because of its prominence in Western society. Common conditions such as diabetes, hypertension and kidney infections can all progress to End-Stage Renal Disease (ESRD) also known as Stage 5 chronic kidney disease (CKD 5). Read more about this study

About this study

Official title: The Use of Bisphosphonates to Prevent or Delay the Progression of Vascular Calcification in End-Stage Renal Disease: A Randomized Controlled Trial

Kidney disease is a fundamental part of medicine because of its prominence in Western society. Common conditions such as diabetes, hypertension and kidney infections can all progress to End-Stage Renal Disease (ESRD) also known as Stage 5 chronic kidney disease (CKD 5). Once ESRD has begun, kidney function is poor at best, thus the body is unable to effectively clear harmful toxins from the blood.

A common feature of ESRD is vascular calcification, a process where blood vessels (especially arteries) attract deposits of the mineral calcium. Over time, these deposits harden and thicken in the layers of blood vessels, which limit blood flow to body tissues and can produce significant disease including hypertension, heart disease and stroke. Although the process of vascular calcification is unknown, there is mounting evidence that it is mediated by cellular events that are similar to those seen in bone formation with in the body (osteogenesis). With this point in mind, it has been suggested that agents medicine employs to limit excess bone formation will reduce the rate of vascular calcification in CKD Stage 5.

This study will employ one group of drugs called bisphosphonates which have been used to limit bone formation. It will study their effect on vascular calcification in adult dialysis patients.

Read the detailed description

Presently, there exist few therapies aimed at retarding the progression of vascular calcification. One study showed that agents that limit the absorption of phosphate from food (phosphate binders) slow the progression of vascular calcification, and as a result, treatments emphasize phosphate control through diet and phosphate binders. Other studies have shown that the use of statins, to lower LDL cholesterol levels may reduce the progression of coronary calcification in non-ESRD patients, but data from ESRD are lacking. While these treatments have been helpful, the improvements in patients' outcomes have not been overwhelming positive.

This proposed study is not the first to study the use of bisphosphonates on vascular calcification. Repeated studies have shown impressive reduction in calcification rates in several animal models, which begs the question, how will bisphosphonates fare in human subjects? Preliminary research has begun, but clearly an expansive trial on humans is needed to explore the use of a promising therapy. Our study hopes to provide insight into this area of cardiovascular research.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Bisphosphonate in people with Chronic Kidney Disease, run by Queen's University at 1 site in Canada.

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 3 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 28 Sep 2015. 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 Canada. 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?

Absolute change in coronary artery calcification score (CaSc) from baseline to study completion. (time frame: 24 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 28 Sep 2015.
