Plain English Summary

Background and study aims
A kidney transplant is the transfer of a healthy kidney from one person into the body of a person who has little or no kidney function. People who receive a kidney transplant usually need to take immunosuppressant medications for the rest of their life to prevent the body's immune system from attacking the new kidney (graft loss). For over 20 years calcineurin inhibitor (CNI) drugs such as tacrolimus have been used for immunosuppression. There are many different causes of graft loss including some risk factors that could be managed through improvement of the immunosuppressive treatment. Approaches taken to improve treatment include adding other immunosuppressive treatments to CNIs, especially those with complementary ways of working and different side effects. Tacrolimus in combination with mycophenolic acid (MPA) is an effective immunosuppressive treatment for kidney transplant recipients. The combination of tacrolimus and sirolimus has also been shown to provide effective immunosuppression. The strong combined immunosuppressive effect of tacrolimus plus sirolimus allows the dose of tacrolimus to be reduced when used in combination with sirolimus. The aim of this study is to compare the use of sirolimus plus tacrolimus with tacrolimus plus mycofenolic acid in kidney transplantation.

Who can participate?
Patients aged 18-65 receiving their first kidney transplant

What does the study involve?
Patients are randomly allocated into two groups. After receiving their kidney transplant one group is treated with sirolimus plus tacrolimus and the other group is treated with tacrolimus plus mycofenolic acid. Both groups are followed up over 1 year after their transplant to assess their kidney function.

What are the possible benefits and risks of participating?
The new treatment may reduce the incidence of viral infections and cancer. As with all immunosuppressive treatments there is a risk of transplant rejection and infections.

Where is the study run from?
Labbafinejad Hospital (Iran)

When is the study starting and how long is it expected to run for?
September 2016 to September 2017

Kidney transplantation


Participants are randomised by block randomisation to group A or B:

Group A:
Thymoglobulin 3mg/kg divided in 3-4 days
Myfortic (mycophenolic acid) 360 mg x 3 for 7 days then 720 mg/d (initial dose should be started from 1 day before TX)
Prograf (tacrolimus) 0.1 mg/kg/d trough level to reach 8-10 ng for 90 d then 5-8 thereafter (initial dose should be started from 1 day before TX)
Prednisolone MP250 x 2 d then 1mg /kg (max 60 mg) x 3 d, taper 5 mg/d, 15 mg at day 14, 10 mg day 30, 5 mg day 60 and thereafter
Ganciclovir during first 8 days
After using ganciclovir Valcyte (valganciclovir hydrochloride) should be used for 90 days

Group B:
Thymoglobulin 3mg/kg divided in 3-4 days
Prograf (tacrolimus) 0.08 mg/kg to reach trough 6-7 ng/ml for 6 m then toward 4-5 after 6 m (initial dose should be started from 1 day before TX)
Rapamune (sirolimus) 2 mg first d within 96 h of surgery then 1 mg/d reaching trough level around 3-5 for first 6 mo then trough 6-8 ng/ml thereafter (sum of sirolimus + tac around 10-12)
Prednisolone MP250 x 2d then 1 mg /kg (max 60 mg) x 3 d, taper 5 mg/d, 15 mg at day 14, 10 mg day 30, 5 mg day 60 and thereafter
Ganciclovir IV during first 8 days
After using ganciclovir Valcyte (valganciclovir hydrochloride) should be used for 90 days

Participants are followed up at 1-14 days, 1 month, 6 weeks, 2 months, 10 weeks, 3 months, 4 months, 5 months, 6 months, 8 months, 10 months and 12 months.
