About this study
Official title: A Pilot Study to Evaluate the Safety and Efficacy of Mycophenolate Sodium (Myfortic®) in Combination With Sirolimus (Rapamune®) in Stable Renal Allograft Recipients
The purpose of this study is to determine whether the combination of Myfortic and sirolimus is effective at preventing rejection while preserving kidney function in stable kidney transplant recipients.
Read the detailed description
One-year graft survival after renal transplantation dramatically improved with the addition of calcineurin inhibitors (tacrolimus or cyclosporine) to maintenance immunosuppression regimens. Much of this improvement in early graft survival has been attributed to the efficacy of the calcineurin inhibitors in preventing early acute rejection episodes. However, long-term graft survival has not improved to as great of a magnitude as the improvements in short-term survival. In addition, research shows progressive decline in kidney function throughout the years post-transplantation. Clinical research now focuses on improving long term graft survival while maintaining long-term kidney function.
The leading cause of graft loss has been attributed to chronic allograft nephropathy (CAN). Risk factors for CAN include: prolonged ischemia time, delayed graft function, acute rejection episodes and calcineurin inhibitor nephrotoxicity (CIN). CIN has been identified as the most common identifiable contributor to CAN and the chief cause of late histologic injury and ongoing decline in renal function. At 10 years post-transplant, CIN has been found to be universally prevalent.
Calcineurin inhibitor minimization and elimination studies have sought to improve long-term allograft function by minimizing exposure to these nephrotoxic agents. Studies have demonstrated that early withdrawal of cyclosporine from a cyclosporine, sirolimus and steroid immunosuppression regimen at 3 months post-transplant improved renal function and graft survival at 48 months post-transplant. Other studies have demonstrated diminished prevalence of CAN at 2 years post-transplant in those patients maintained on sirolimus as compared with cyclosporine. Kidney function was also significantly improved with lower serum creatinine and higher GFR in the sirolimus maintenance group.
Sirolimus is a macrolide antibiotic immunosuppressive agent that exerts its mechanism of action by inhibiting the mTOR signaling cascade. In clinical trials, sirolimus was found to lack nephrotoxic effects when compared to cyclosporine. In kidney transplantation, multiple studies have demonstrated safety and efficacy of sirolimus in calcineurin inhibitor avoidance and withdrawal protocols.
Myfortic® (mycophenolate acid) is an enteric coated formulation of mycophenolic acid (MPA) approved for the prevention of rejection in kidney transplant recipients in combination with cyclosporine and corticosteroids. Myfortic® has no documented nephrotoxic effects. Mycophenolate mofetil (MMF), a prodrug of MPA also does not demonstrate nephrotoxic effects. Early studies have demonstrated therapeutic equivalence between Myfortic® and MMF both in de novo renal transplants and in conversion studies where MMF is converted to Myfortic at least 6 months after renal transplantation. Thus, studies demonstrating safety and efficacy of MMF with sirolimus in calcineurin inhibitor withdrawal protocols should also hold true using Myfortic® in such regimen.
This study will assess the safety and efficacy of Myfortic® when used in a simultaneous sirolimus conversion and calcineurin inhibitor withdrawal regimen in stable renal transplant recipients. Study subjects will receive immunosuppression consisting of Myfortic®, tacrolimus and corticosteroids (prednisone) starting the day of transplant. Conversion from tacrolimus (Prograf) to sirolimus (Rapamune) will occur between 90 and 180 days post cadaver-donor or living-donor renal transplant. All participants will be converted from tacrolimus to sirolimus and remain on Myfortic® and their current corticosteroid taper.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing sirolimus in people with Renal Transplantation, run by California Pacific Medical Center Research Institute at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 27 Oct 2020. 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 United States. 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?
Yes. Results are posted in the registry (first posted 27 Oct 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Renal Allograft Function (time frame: six months). 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 NCT00713284, which also lists 14 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 27 Oct 2020.
