About this study

Official title: A 6-month, Prospective, Open-label, Randomized, Controlled, Pilot Study Evaluating the Efficacy, Safety and Toxicity of an Optimized Immunosuppressive Regimen of CellCept (Mycophenolate Mofetil, MMF) and Reduced Doses of Both Calcineurin-inhibitors and Prednisone in Renal Transplant Recipients With an Increased 10-year Coronary Heart Disease Risk

The purpose of this research study is to determine if adding or increasing the dose of CellCept while lowering the dose of tacrolimus (Prograf or Advagraf) or cyclosporine (Neoral), and/or steroids can reduce the likelihood of developing coronary heart disease in the next 10 years.

The investigators will calculate the change in risk of developing coronary heart disease using the Framingham score. The Framingham score is a mathematical equation that includes the following information: Age, Gender, Diabetes status, Smoking status, Lipids, Blood Pressure. The Framingham score estimates how likely it is that someone will develop coronary heart disease over the next 10 years.

Read the detailed description

Kidney transplant recipients are required to take medications called immunosuppressants to lower their immune systems to help protect the donated kidney. The medications have improved over the years and as a result the donated kidneys are generally working longer. This allows the Transplant Team to focus more on the long term complications of kidney transplantation such as cardiovascular disease.

There have been few prospective (looking forward) research studies looking at kidney transplant recipient cardiovascular risk factors after transplant.

We know that immunosuppressive medications have a number of serious side effects that can increase cardiovascular disease risk factors such as high blood pressure, high lipids (fats in the blood), and high blood sugar. Medications such as tacrolimus, cyclosporine and prednisone work well to protect the donated kidney but are also known to increase the risk of developing or worsening cardiovascular disease.

CellCept is another type of immunosuppressive agent. CellCept is not associated as much with the risk of developing cardiovascular disease.

This is a pilot study being done to collect information about cardiovascular risk factors in kidney transplant recipients and to see if adjusting the immunosuppressive medications can help to lower the overall risk for developing heart disease in the future.

This research study plans to enroll 45 participants from 2 different transplant centres in Canada: St. Michael's Hospital in Toronto and St. Paul's Hospital in Saskatoon. The study duration is approximately 7 months per participant. The study will be looking for participants who are 30 years of age or older and who are at least 6 months after the transplant operation.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • mycophenolate mofetilDrug

    Also called CellCept, MMF

    Introduction of CellCept or increase in the dose of CellCept to a maximum of 2 g/day. In patients not already receiving CellCept, azathioprine (AZA), enteric-coated mycophenolate sodium (EC-MPS) or sirolimus (SRL) will be discontinued and replaced by CellCept in divided doses to a maximum of 2 g/day. CNI doses will be reduced to conform to the target trough levels in the low-dose CNI arms of the ELITE-Symphony study +/- steroid dose reduction. Any CNI dose change will require measurement of CNI trough levels at 7 days post dose change +/- 3 days.

    Target CNI trough levels in the Symphony study:

    • Low-dose CsA: Initial oral dose of 1-2 mg/kg bid, to achieve a target trough level of 50-100 ng/mL.
    • Low-dose TAC: Initial oral dose of 0.1 mg/kg/day divided into two doses* with a target trough level of 3-7 ng/mL (*Advagraf may also be used at a dose of 0.1 mg/kg once daily with a target trough level of 3-7 ng/mL)

  • standard immunosuppressionOther

    Current immunosuppressive therapy will be maintained throughout the study unless a change is required for safety reasons.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing mycophenolate mofetil and standard immunosuppression in people with Kidney Transplantation and Cardiovascular Diseases, run by Ramesh Prasad 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 12 inclusion and 20 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: stopped early, as of the sponsor's last update on 19 Apr 2012. 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. 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 was stopped early (reason given: Poor recruitment.). Results are not available in the source record.

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?

The change in the Framingham 10-yr age and gender adjusted score for coronary heart disease from baseline to Month 6 (time frame: Baseline to Month 6). The study lists 2 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 NCT01213394.

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 19 Apr 2012.
