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).

Condition or disease Intervention/treatment Phase
Renal Transplant Drug: Mycophenolate mofetil (CellCept® ) Phase 4

Detailed Description:
Patient will be randomized into two treatment groups on a 1:1 ratio. Both groups will be treated with the same drugs which is the usual treatment for avoiding renal transplant rejection. In one group the CellCept® dose will be adjusted based on MPA concentration value which will be monitored periodically; and the second group will be treated with CellCept® Fixed Dose (based on the clinical judgment of the treating physician).

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 138 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase IV, Open-Label, Multicenter, Randomized Study Comparing Mycophenolate Mofetil (MMF) Dose Adjustment Based on Blood MPA Concentration to Standard Care Treatment With MMF in Renal Transplant Recipients Receiving Tacrolimus
Study Start Date : August 2008
Estimated Primary Completion Date : August 2011
Estimated Study Completion Date : August 2013

Arm Intervention/treatment
Experimental: 1
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® )
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.
Other Names:
  • CellCept®
  • MMF

Active Comparator: 2
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® )
Fixed Dose group, MMF dosage will be adjusted based on standard care

Primary Outcome Measures :
  1. Primary Endpoint Treatment failure defined as a biopsy proven acute rejection, graft loss, death, MMF discontinuation or lost to follow-up. [ Time Frame: During the first 12 months following randomization. ]
