A Study of CellCept (Mycophenolate Mofetil) in Combination Therapy in Liver Transplant Patients.

9 de junio de 2014 actualizado por: Hoffmann-La Roche

A Randomized, Open Label Study Comparing the Effect of CellCept With Therapeutic Drug Monitoring, Tacrolimus and a Corticosteroid-sparing Regimen Versus Fixed Dose CellCept, Tacrolimus and Corticosteroids Maintained up to 6 Months, on Acute Rejection and Safety in Liver Transplant Patients.

This 2 arm study will compare the efficacy and safety of two CellCept-containing treatment regimens in de novo liver transplant patients. Patients will be randomized into one of two groups, to receive either CellCept (at a starting dose of 3g/day po, adjusted according to exposure) standard dose tacrolimus and corticosteroids (10-15 mg/kg i.v. on day 0), or fixed dose CellCept 2g/day po, standard dose tacrolimus and corticosteroids (10-15mg/kg i.v. on day 0, then reducing from 20mg to 5mg over 6 months, and discontinuing after 6 months). The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

Medida Descripción
Periodo de tiempo
Percentage of Participants With Treated Biopsy Proven Acute Rejection (BPAR) According to Banff Criteria up to 12 Months Post-Transplant
Periodo de tiempo: Days 0, 5, and 14, Month 1, 2, 3, 6, 9, and 12, 28 days after Month 12 or last dose of study treatment, and 6 and 12 months after the last dose of study treatment
Banff criteria required at least 2 of the 3 following features for a histopathological diagnosis of acute rejection: portal inflammation, bile duct inflammation, and venous endothelial inflammation. Each item was graded from 0 to 3 where 0 equals (=) mild, 2 = moderate, and 3 = severe. The sum of the 3 individual scores, from 0 to 9, corresponded to the Rejection Activity Index (RAI). If RAI = 0, 1, or 2, there was no evidence of rejection. If RAI = 3, there was borderline acute rejection. If RAI = 4 or 5, there was mild acute rejection. If RAI = 6 or 7, there was moderate acute rejection. If RAI = 8 or 9, there was severe acute rejection.
