Status Completed

Clinical Trial Summary

The purpose of this study is investigate mycophenolic acid exposure through area under the curve in renal transplants recipients treated with mycophenolate mofetil and after conversion to mycophenolate sodium.

Clinical Trial Description

A growing body of evidence has shown that mycophenolate acid (MPA) exposure assessment and dosage adjustment are necessary in patients treated with mycophenolate mofetil (MMF), but there is still limited information about the dose-exposure-effect relationship of the enteric-coated mycophenolate sodium (EC-MPS) formulation that has quite different physicochemical properties (TETT et al., 2011).

Pharmacokinetically guided exposure-controlled area under the concentration-time curve (AUC) approaches are helpful to limit interpatient variability of MPA exposure and to improve the clinical outcome of organ transplant recipients (TETT et al., 2011).

MPA area under the concentration-time curve values between 30 and 60 μg h/mL in the early post-transplant period reduces the risk of acute rejections and seems to be appropriate in renal allograft recipients taking mycophenolate sodium (MPS) and calcineurin inhibitors (GRINYÓ et al., 2009; SOMMERER et al., 2010).

Among the benefits of therapeutic drug monitoring of MPA are the evaluation of interaction between MPA and proton pump inhibitors and association of donor-specific antibodies reduction. ;
