About this study

A pilot randomized trial that compares a new renal nutritional supplement with the standard renal vitamin.

The primary objective is to compare two doses (medium and high) of the new supplement with the renal vitamin currently being prescribed to people with End Stage Renal Disease (ESRD).

Secondary objective is to demonstrate the feasibility of recruitment for a definitive larger trial.

Read the detailed description

People with severe kidney disease follow a restricted diet aimed at reducing intake of sodium, potassium and phosphate. These dietary restrictions require reducing their intake of many fresh fruits and vegetables, which may lead to nutritional deficiency. Although the potential for malnutrition in people with kidney disease is well recognized, blood levels of most vitamins and trace elements are rarely measured. Instead, most North Americans with severe kidney disease are routinely prescribed a "renal vitamin" such as Replavite which contains a mixture of B and C vitamins.

Recent evidence (including our work; see http://www.biomedcentral.com/bmcmed/subjects/nephrology) indicates that people with severe kidney disease are often deficient in several other biologically essential substances (selenium, zinc) that are readily amenable to supplementation. Pilot data from the Northern Alberta Renal Program (NARP) indicate that approximately 90% of patients have zinc levels below the lower limit of normal; findings for selenium are similar.

Potential benefits of zinc supplementation include improvements in immune function, taste sensitivity (perhaps reducing dietary sodium intake), and improved appetite. Potential benefits of selenium supplementation include reductions in the risk of vascular disease and infection. Supplementation with vitamin E was shown in a randomized trial to reduce serious cardiovascular morbidity in people with kidney failure, but is not routinely used in dialysis patients. This suggests that supplementation of zinc, selenium, and vitamin E has theoretical benefits in kidney failure. Since patients with kidney failure already take many medications, it is logical to combine any new nutritional supplements with the ingredients of the standard renal vitamin to reduce pill burden.

This protocol concerns a novel nutritional supplement consisting of zinc, selenium and vitamin E in addition to the contents of the standard renal supplement of B and C vitamins.

This pilot randomized, double blind trial will compare 2 doses of the new supplement with the standard renal vitamin.

2.0 Objectives: Primary objective: compare two formulations of the new supplement (low and medium doses of zinc and selenium) with standard treatment (Replavite or equivalent renal vitamin).

Secondary objective: demonstrate the feasibility of recruitment for a definitive larger trial

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of participants with zinc deficiency

    Proportion of participants with zinc deficiency in the combined experimental arms compared to the proportion of participants with zinc deficiency in the active comparator arm.

    Measured: 90 days following baseline

Secondary outcomes (4)
  1. Proportion of participants with zinc deficiency

    The proportion of participants with zinc deficiency in each arm compared to each other arm at each time point.

    Measured: 180 days following baseline

  2. Proportion of participants with selenium deficiency

    The proportion of participants with selenium deficiency in each arm compared to each other arm at each time point.

    Measured: 90 days and 180 days following baseline

  3. Zinc

    Zinc concentration in each arm compared to each other arm.

    Measured: 90 days and 180 days following baseline

  4. Selenium

    Selenium concentration measured in each arm compared to each other arm.

    Measured: 90 days and 180 days following baseline

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Low dose: supplemental zinc, selenium and vitamin E, Standard renal vitamin: B and C renal vitamin and Medium dose: supplemental zinc, selenium and vitamin E in people with End Stage Renal Disease, run by Marcello Tonelli at 2 sites 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 4 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 16 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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?

Proportion of participants with zinc deficiency (time frame: 90 days following baseline). 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 NCT01473914, which also lists 2 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 16 Dec 2016.
