A Study of the Correlation Between Pharmacokinetic and Pharmacodynamic Parameters of CellCept (Mycophenolate Mofetil).
8. dubna 2016 aktualizováno: Hoffmann-La Roche
Relationships Between Pharmacokinetic and Pharmacodynamic Strategies for Assessment of the Risks for Acute Rejection and Side Effects of Mycophenolate Mofetil
This study will evaluate the correlation between the pharmacokinetic and pharmacodynamic parameters of CellCept in patients undergoing primary kidney transplantation, in order to assess the impact on clinical outcome and the risks of acute rejection.
All patients will receive oral CellCept, 1g twice daily, and pharmacokinetic and pharmacodynamic parameters will be measured at weeks 2, 4, 12 and 24.
The anticipated time on study treatment is 24 weeks.

Grade IB was defined as significant interstitial infiltration with >25% parenchyma affected, and foci of severe tubulitis with >10% mononuclear cells per tubular cross section or group of 10 tubular cells.
Grade IIA was defined as mild to moderate intimal arteritis.
Grade IIB was defined as severe intimal arteritis comprising >25% of the luminal area.
Grade III was defined as transmural arteritis and/or arterial fibrinoid changes and necrosis of medial smooth muscle cells.
