Brief Summary

In order to avoid renal transplant rejection, the immune system should be suppressed. After the renal transplant subjects are treated with a combination of two to four different types of immunosuppressive drugs. Theses drugs are very efficient in the prevention of the renal transplant rejection. Still, they can cause side effect. Research in renal transplant tries to find the best treatment in order to avoid renal rejection on one hand and to reduce as much as possible the undesired adverse and toxicity effects on the other hand. Therapeutic efficacy and the onset of adverse effects are influenced by levels of mycophenolic acid (MPA, the active metabolite of MMF, CellCept®). The primary objective of this study is to assess the treatment superiority of CellCept® Dose Adjustment treatment, based on individual MPA concentration value monitored periodically, against treatment with CellCept® Fixed Dose (standard care).

Renal Transplant

Keywords

Renal Transplant; Renal; Transplant; MMF; MPA; Recipients

Outcome Measures

Primary Outcomes (1)

• Primary Endpoint Treatment failure defined as a biopsy proven acute rejection, graft loss, death, MMF discontinuation or lost to follow-up.

  During the first 12 months following randomization.

Study Arms (2)

1

EXPERIMENTAL

Concentration Controlled (CC)group will receive an individually adjusted MMF dosing regimen based on the plasma concentrations of mycophenolic acid (MPA,the active metabolite of mycophenolate mofetil).

Drug: Mycophenolate mofetil (CellCept® )

2

ACTIVE COMPARATOR

Fixed dose (FD) group will receive an a priori set dose of 2mg\\day MMF, the recommended dose, with a possible secondary adaptation by the clinician based on criteria of clinical efficacy, toxicity or interactions with other medications.

Drug: Mycophenolate mofetil (CellCept® )

Interventions

Mycophenolate mofetil (CellCept® ) DRUG

Concentration Control group: MMF dosage will be adjusted (by addition or subtraction of least 250 mg of MMF twice a day) based on MPA levels (MPA AUC target of 40 mg\*h\\L) measured on Days 7,14,Months 1,3,6 and 12.

Also known as: CellCept®, MMF
