Mycophenolate Mofetil for Reducing Cardiovascular Risk in Renal Transplant Recipients

• Status: Terminated
• Trial end date: 2011-12-01
• Target enrollment: 0
• Participant gender: All

Summary

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.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Ramesh Prasad
• Collaborator: Hoffmann-La Roche
• Treatments: Calcineurin Inhibitors; Immunosuppressive Agents; Mycophenolate mofetil; Mycophenolic Acid

Criteria

Inclusion Criteria:

1. Renal transplant recipients who are ≥ 6 months post-day of transplant surgery.

2. Single organ kidney recipient (may be for first or repeat transplant).

3. Age ≥ 30 years of age as of the Day 0 visit.

4. Immunosuppressive regimen consisting of a CNI (cyclosporine [CsA, Neoral] or tacrolimus [TAC, Prograf or Advagraf], corticosteroids and either MMF (CellCept), EC-MPS (Myfortic), AZA (Imuran) or SRL (Rapamune) at the baseline visit. Patients are to be maintained on the same dose(s) for at least 4 weeks prior to study enrolment.

5. If the patient is taking an MPA immunosuppressant at the time of the screening visit, the MMF (CellCept) dose must be ≤ 1500 mg/day; or the EC-MPS (Myfortic) dose must be ≤ 1080 mg/day.

6. Framingham risk factor score that exceeds the low comparative 10-year CHD risk, based on age and gender.

7. Presence of at least one established CV risk factor at baseline warranting modification of the immunosuppressive regimen including:

• Hypertension: Blood pressure ≥ 140 mmHg systolic and/or ≥ 90 mmHg diastolic and/or requiring ≥ 1 antihypertensive medication.

• Diabetes mellitus: Established diabetes requiring treatment with oral hypoglycemic agents or insulin, or known IFG or IGT based on 75-g oral glucose tolerance testing (2003 Canadian Diabetes Association criteria).

• Hyperlipidemia: TC ≥ 5.2 mmol/L, or LDL-C ≥ 2.6 mmol/L, or TG ≥ 1.7 mmol/L, or TC:HDL ≥ 4 and/or requiring ≥ 1 anti-hyperlipidemia agent.

8. Willingness and ability to complete protocol requirements.

9. Written informed consent.

Exclusion Criteria:

1. Contraindication to receiving MMF (CellCept) or increasing CellCept dose.

2. Clinically suspected acute rejection (AR) or BPAR within 3 months prior to the baseline visit.

3. Proteinuria ≥ 1 g/24 hours

4. Treatment with AZA (Imuran), EC-MPS (Myfortic) or SRL (Rapamune) and patient or physician decision not to discontinue these agents and switch to MMF (CellCept) at the time of randomization.

5. MDRD (4-variable) eGFR < 15 mL/min/1.73 m2

6. Patients who currently exceed thresholds for plasma glucose, cholesterol or blood pressure. Patients may be re-considered 1 month after the treatment is in place and no further therapeutic changes are anticipated.

7. Patients who require changes to their blood pressure, blood sugar or blood lipid management between the Screening Visit and Day 0. Patients may be re-considered 1 month after the adjusted treatment is in place and no further therapeutic changes are anticipated.

8. Pregnancy, lactation or (for women of childbearing potential) inability or decision not to use a reliable method of contraception for the entire study duration.

9. Active infection requiring treatment.

10. Treatment with unlicensed investigational drugs, devices or other prohibited medications - see Section 4.4.1

11. Participation in any other interventional clinical trial during the previous 4 weeks or during this trial.

12. History of malignancy, other than non-melanoma skin cancer that has been totally excised and has not recurred for >2 years.

13. History of psychological illness or condition that could interfere with the patient's ability to understand or comply with the study requirements.

14. Presence of other significant diseases or issues which, in the opinion of the sponsor-investigator, may:

• Put the patient at risk as a result of study participation

• Influence the study result

• Affect the patient's ability to participate in the study

• Require a change in immunosuppression medication used or a dose change within the next 6 months (unstable renal function, gout that may require treatment with prednisone, etc)

• Reduce life expectancy. Examples include but are not limited to history of noncompliance and transportation issues that could affect a participant's ability to successfully complete the study requirements. Inability or refusal to provide blood samples, end-stage disease of organs such as lung, liver or heart.

15. Exclusion of patients who are hypersensitive to CellCept (mycophenolate mofetil), mycophenolic acid or any component of the drug).
