Pharmacokinetics of Mmf and Valganciclovir

Completed · Phase 4

Conditions studied: Kidney Transplant Recipient, Heart Transplant Recipient

In brief

The primary objective of this study is to determine whether a clinically significant PK drug interaction ( a 30% difference in the AUC of MPA) exists between mycophenolate mofetil (under steady state conditions) and VGCV in renal and cardiac transplant recipients. This study will provide clinically relevant information to the transplant community. It will more clearly delineate whether a clinically significant PK drug interaction exists between mycophenolate mofetil (under steady-state conditions)and VGCV. Given the established dose/efficacy relationship of both MMF and VGCV, this study will provide improved dosing guidelines and potentially avoid adverse outcomes due to empiric dosage adjustments.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• The subject must be able to give informed consent for the study. Stable renal or cardiac transplant patients age 18 years and older. Patients must not have had an acute rejection episode within the previous 30 days of the 1st PK study.
• Renal transplant patients with serum creatinine < 2 mg/dL and with change in serum creatinine < 25% within the 2 weeks prior to the 1st PK study.
• Renal and cardiac transplant patients receiving VGCV for prophylaxis of CMV while concomitantly receiving MMF.
• Stable MMF dose: the dose of MMF must not have been adjusted within 1 week of the 1st PK study and must be the same during the 2nd PK study Stable renal function during the study period (change in serum creatinine < 25%)

You may not qualify if…

• Patients who are not prescribed MMF maintenance therapy or are receiving Myfortic.
• Patients who do not require VGCV prophylaxis (CMV negative recipients of CMV negative donor organs).
• Patients who have their MMF doses adjusted either < 1 week before the 1st scheduled PK study or anytime during the study period.
• Patients whose serum creatinine changes by > 25% within 2 weeks prior to study initiation.
• Patients whose hematocrit < 28%. Patients who received other organ transplants in addition to a kidney or heart. Patients who are pregnant or breast-feeding. Patients prescribed bile acids, bile acid sequestrants, potassium binding resins, or magnesium/aluminum-containing antacids.
