Study of Therapeutic Monitoring of Mycophenolate Mofetil (MMF/CellCept) After Kidney Transplantation

Phase 4
Completed
Conditions
Kidney Transplantation
Interventions
Registration Number
NCT00087581
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This three-arm study will evaluate the efficacy and safety of various dosing regimens of MMF combined with various dosing regimens of calcineurin inhibitor (CNI), either cyclosporine or tacrolimus, in participants who have undergone kidney transplantation. Participants will be randomized to one of three dosing regimens to receive concentration-controlled MMF with reduced CNI, concentration-controlled MMF with standard CNI, or fixed-dose MMF with standard CNI. Participants will be followed for 20-24 months after randomization.

GroupInterventionDescription
Group A: Monitored MMF + Reduced CNIMycophenolate mofetilGroup A will receive concentration-controlled/monitored MMF with an oral CNI, either cyclosporine or tacrolimus. Depending on body surface area and age, MMF may be given in capsule, tablet, oral suspension, or intravenous (IV) form. The initial dose will be at least 1 gram twice a day (BID) in adults and 600 milligrams per meter-squared (mg/m\^2) in pediatrics. Subsequent doses will be adjusted to maintain blood mycophenolic acid (MPA) levels greater than or equal to (≥) 1.3 micrograms per milliliter (μg/mL) with cyclosporine or ≥1.9 μg/mL with tacrolimus. The selected CNI will be dosed to maintain reduced blood concentrations. Cyclosporine target concentrations are as follows: Days 1-30, 250-325 nanograms per milliliter (ng/mL); Days 30-90, 125-165 ng/mL; Days 90 through end of study, 95-145 ng/mL. Tacrolimus target concentrations areas follows: Days 1-30, 8-12 ng/mL; Days 30-90, 4-6 ng/mL; Days 90 through end of study, 3-5 ng/mL.
Group B: Monitored MMF + Full CNITacrolimusGroup B will receive concentration-controlled/monitored MMF with an oral CNI, either cyclosporine or tacrolimus. Depending on body surface area and age, MMF may be given in capsule, tablet, oral suspension, or IV form. The initial dose will be at least 1 gram BID in adults and 600 mg/m\^2 in pediatrics. Subsequent doses will be adjusted to maintain blood MPA levels ≥1.3 μg/mL with cyclosporine or ≥1.9 μg/mL with tacrolimus. The selected CNI will be dosed to maintain standard/full blood concentrations. Cyclosporine target concentrations are as follows: Days 1-30, 250-325 ng/mL; Days 30-90, 250-270 ng/mL; Days 90 through end of study, 190-220 ng/mL.
