Trial summary

The overall goal of this study is to improve cardiovascular outcomes in transplant recipients. The current standard immunosuppressive regimen in kidney transplant recipients depends on a higher exposure to the Calcineurin Inhibitor (CNI), and often a less than optimal dosage the of mycophenolic acid (MPA) derivative.

About this study

Official title: Comparisons Of Inflammatory Biomarkers And Cardiovascular Risk Scores Before And After Conversion To Full Dose Myfortic® Using Two Hour Neoral® Monitoring.

The overall goal of this study is to improve cardiovascular outcomes in transplant recipients. The current standard immunosuppressive regimen in kidney transplant recipients depends on a higher exposure to the Calcineurin Inhibitor (CNI), and often a less than optimal dosage the of mycophenolic acid (MPA) derivative. The premise of this study is to investigate the effects of reversing this paradigm. More specifically, the effect of using maximum MPA dosages (in the form of enteric-coated mycophenolate sodium [EC-MPS] or Myfortic®) along with judicious CNI exposure (cyclosporine/Neoral®) will be investigated.

Read the detailed description

Research Question:

Will treating kidney transplant recipients with maximum MPA dosages (in the form of EC-MPS or Myfortic®) along with judicious CNI exposure (cyclosporine/Neoral®) lead to improved cardiovascular outcomes, as measured by the Framingham Risk Score, 7-year major adverse cardiac events (MACE) score and cardiovascular risk inflammatory biomarker profile?

Primary Objectives:

  1. To improve the Framingham Risk Score and 7-year MACE score for renal transplant recipients, which estimate risk for cardiovascular disease.
  2. To improve the cardiovascular risk inflammatory biomarker profile.

Hypothesis:

The more consistent drug exposure and lower Cmax noted with monitoring cyclosporine using the 2h levels (C2) combined with full dose Myfortic® will decrease Framingham Risk Score, MACE score, as well as markers of inflammation in kidney transplant recipients because:

  1. CNI minimization protocols are widely accepted as a strategy to ameliorate allograft and vascular injury.
  2. Chronic allograft injury and vascular disease are known inflammatory conditions.
  3. The MPA derivatives possess significant anti-inflammatory properties.

Observation GroupNo intervention25 patients continued on an mycophenolic acid (MPA) derivative, tacrolimus, and prednisone will be followed during the same recruitment period as an additional comparison, as this is the other Calcineurin Inhibitor (CNI), which is used in kidney transplantation.

What is being measured

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

  1. Change in Framingham score for renal transplant recipients.

    Cardiovascular risk factors using the Framingham 2009 risk score for renal transplant recipients and at end of the one year.

    Measured: 1 year

  2. Surrogate markers for potential biological differences between the groups.

    Cardiovascular (CV) Biomarkers compared between each group. CV Biomarkers of interest in this study include:

    1. Chemokines (including ccl 1, 2, 15 and Clx 9 and 10)
    2. Thrombopoitin
    3. Cytokines IL 1, 2, 4, 6, 10, TGF, INF.

    These mediators are known to play a pivital role in atherosclerosis and progressive kidney failure.

    Measured: 1 year

  3. Safety Measures

    Safety will be measured by estimated Glomerular filtration rate (GFR).

    Measured: 1 year

  4. Change in 7-year MACE score for renal transplant recipients.

    Cardiovascular risk factors using the 7-year MACE calculator for renal transplant recipients and at end of the one year.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Myfortic®, Neoral® and Cellcept® in people with Cardiovascular Disease and Cardiovascular Outcomes, run by University of Saskatchewan 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 8 inclusion and 13 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: withdrawn, as of the sponsor's last update on 9 Jan 2017. 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 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 was withdrawn before enrolling participants, so there are no results.

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?

Change in Framingham score for renal transplant recipients. (time frame: 1 year). The study lists 4 primary outcomes in all. 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 NCT02058875, which also lists 44 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 9 Jan 2017.
