Prospective Donor Specific T Response Measurment for IS Minimization in de Novo Renal Transplantation

Tacrolimus (for Group B) will be administered orally twice a day (bid). Tacrolimus (for Group B) will be initially given at the 0,1mg/kg bid to achieve a stable 12-hour trough level of 8-10 ng/mL during the first month after transplantation to progressively tapper to 6-8ng/ml thereafter.

"MMF (mycophenolate mofetil) will be administered orally to patients in group B at conventional doses (1gr/12h) before transplant procedure and during the first 7 days after transplant. For subjects who develop nausea, diarrhea, or other MMF(mycophenolate mofetil) -related gastrointestinal adverse effects (eg, symptoms fully assessed and deemed not to have an etiology other than intolerability to MMF), the MMF(mycophenolate mofetil) dose may be decreased to the maximally tolerated dose.~Subjects unable to tolerate the reduced dose may be converted to mycophenolate sodium (Myfortic™) or to Myfenax.~From day 8 on, patients will not receive MMF."

"At the time of surgery, all patients will receive 500mg of 6-methyl prednisolone (Steroids, Urbason, Methypred).~Patients in group B will receive 250mg of 6-methyl prednisolone (or equivalent) on day 2, 125 mg on day 3, 60 mg on day 4 and 30 mg on day 5. From day 6 on, patients will receive 0.25 mg/kg/d of 6-methyl-prednisolone (Steroids, Urbason, Methypred) until month 1, then tapering until discontinuation on month 2 will be performed."

"The study group A will receive Tacrolimus (for Group A) (Prograf) to achieve 4-8 ng/ml trough levels during all the duration of the study.~Tacrolimus (for Group A) (Tacrolimus) capsules should generally be administered on an empty stomach or at least 1 hour before or 2 to 3 hours after a meal, to achieve maximal absorption."

"Mycophenolate mofetil (MMF) (Cellcept, Myfortic, Myfenax) (for Group A) will be administered orally to patients in group A at conventional doses (1gr/12h). For subjects who develop nausea, diarrhea, or other Mycophenolate mofetil (MMF) (for Group A) -related gastrointestinal adverse effects (eg, symptoms fully assessed and deemed not to have an etiology other than intolerability to Mycophenolate mofetil (MMF) (for Group A), the Mycophenolate mofetil (MMF) (for Group A) dose may be decreased to the maximally tolerated dose.~Subjects unable to tolerate the reduced dose may be converted to mycophenolate sodium (Myfortic™).~The first dose of Mycophenolate mofetil (MMF) (for Group A) should be administered before transplantation."

"At the time of surgery, all patients will receive 500 mg of 6-methyl prednisolone (steroids for Group A).~Patients in arm A will receive 20 mg/day of 6-methyl prednisolone (steroids for Group A) (or the equivalent) during the first 2 weeks after transplantation, then tapering to 15 mg from week 3 to week 4 to finally be maintained at 5mg/day."
