Pediatric Kidney Transplant Study of Sirolimus, Mycophenolate Mofetil, and Corticosteroids vs Calcineurin Inhibitor Based Immunosuppression

• Status: Completed
• Trial end date: 2012-11-01
• Target enrollment: 0
• Participant gender: All

Summary

Damage and scarring of a transplanted kidney has become the most common cause of loss of the transplanted kidney. This kidney damage is a complex process caused by many factors including injury during obtaining and transplanting the kidney, injury from the immune system, injury from infections, and injury from drugs used to stop rejection. This injury leads to scars that decrease the kidney's ability to function properly, and over time the kidney is lost. Prograf® (tacrolimus) has been one of the main drugs used to prevent rejection. However, when used over time it has been shown to cause chronic damage and scarring in the transplanted kidney.

The purpose of this experimental study is to determine whether children can safely be withdrawn from Prograf® after transplantation and changed to Rapamycin® (sirolimus). Recent research studies in adult transplantation have demonstrated that with the use of Rapamycin® (sirolimus), it is possible to discontinue the use of Prograf (tacrolimus) with no increase in rejection, with decreased scarring in the kidney, and with improvements in kidney function and survival of the kidney. A total of 50 children will enroll in this study at university centers around the country. This study will last about 3 years.
