Pilot Study for HLA Identical Living Donor Renal Transplant Recipients

Overview

The purpose of this study is to evaluate the safety and effectiveness of a steroid-free and calcineurin-inhibitor free treatment regimen for patients who are receiving a kidney transplant from a living donor that is HLA-identical (has a similar immune system).

The purpose of this study is to evaluate the safety and effectiveness of a steroid-free and calcineurin-inhibitor free treatment regimen for patients who are receiving a kidney transplant from a living donor that is HLA - identical, or in other words, has a similar immune system. The immune system is a defense system that the body uses to fight foreign substances that enter the body, such as a transplanted kidney. Two people with similar immune systems are less likely to fight off or reject an organ donated from one to the other. HLA-identical kidney transplant recipients are less likely to need large amounts of immunosuppression because they are immunologically similar. In this study, you will be treated with the immunosuppressive medications, Cellcept, Rapamune, and Prograf and after a rejection free period will remain on Cellcept alone. This treatment regimen is currently being used at The University of Cincinnati for all HLA-identical living donor kidney transplant recipients. This study is being conducted to determine if the protocol currently being used results in beneficial outcomes for HLA-identical kidney transplant recipients. Only recently have transplant centers considered avoiding steroid therapy (prednisone) in any transplant patient because steroids have been used successfully for so long, but with many side effects. The ability to stop steroids has occurred due to the availability of newer more effective immunosuppressive medications. Stopping steroids has been tried in patients who are considered to be at both low and higher risk of kidney rejection. Patients considered at risk for rejection may typically be left on steroids forever or no attempts to stop the steroids would be made until the patient is one year after transplant and has already received a lot of steroid therapy resulting in side effects. This study will be conducted in patients that are low risk for rejection and can potentially benefit from steroid avoidance. Overall, the concept of steroid avoidance in patients that are at low risk for rejection is now much more acceptable because newer, more potent medications have recently become available to prevent acute rejection. These newer medications include Prograf (tacrolimus), Cellcept (mycophenolate mofetil), and Rapamune (sirolimus). Currently, most kidney transplant recipients receive medications consisting of tacrolimus or cyclosporine, mycophenolate mofetil or azathioprine, and steroids. However, recently, the combination of Prograf (tacrolimus) and Rapamune (sirolimus) with steroid withdrawal 3 months after transplantation was studied in patients receiving liver, liver/kidney, and kidney/pancreas transplants. This study showed a low rate of acute rejection with excellent patient and kidney survival. The addition of Cellcept to Prograf and Rapamune is thought to be a safe and effective alternative to the use of steroids in transplant patients. Due to the low risk of rejection for HLA-identical kidney transplant recipients, patients in this study will be slowly withdrawn from both Rapamune and Prograf over a rejection free period of time. Withdrawal of these medications and avoidance of steroids could decrease the development of high blood pressure, high cholesterol, diabetes, tremors, and infection after transplant. This study will determine if this medication regimen is safe, effective, and able to produce beneficial post transplant outcomes.
