CellCept® Dose Adjustment Versus Fixed Dose (Standard Care) in Renal Transplant Recipients
- Registration Number
- NCT00737659
- Lead Sponsor
- Rabin Medical Center
- 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).
- 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).

Group Intervention Description 2 Mycophenolate mofetil (CellCept® ) 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. 1 Mycophenolate mofetil (CellCept® ) 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).
