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

Phase 4
Completed
Conditions
Liver Transplantation
Interventions
Registration Number
NCT00545402
Lead Sponsor
Hoffmann-La Roche
Brief Summary

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.

MMF, Adjusted Dose; Tacrolimus; CorticosteroidsMycophenolate mofetil, adjusted doseParticipants received mycophenolate mofetil (MMF) 3 grams per day (g/d), orally (PO), twice per day (BID) with meals from Day 0 to Day 4; the dose was adjusted based on total exposure (AUC) using the Bayesian method with limited sampling strategy on Days 5 and 14, Months 1, 13, 6, 9, and 12. Participants also received tacrolimus adjusted to a target trough level of 8 to (-) 12 nanograms per milliliter (ng/mL) from Day 0 to Month 1; the dose was adjusted to reach a target trough level of 3-8 ng/mL from the end of Month 1 through Month 12. Participants also received corticosteroids 10-15 milligrams per kilogram (mg/kg), intravenously (IV), pre-operation on Day 0.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Treated Biopsy Proven Acute Rejection (BPAR) According to Banff Criteria up to 12 Months Post-TransplantDays 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.
