A Study of CellCept (Mycophenolate Mofetil) Combined With Tacrolimus and Corticosteroids in Kidney Transplant Patients.

July 8, 2014 updated by: Hoffmann-La Roche

A Randomized, Open Label Study Comparing the Effect of CellCept Combined With Low Dose Versus Standard Dose Tacrolimus, and Corticosteroids, on Kidney Function in Renal Transplantation Patients

This 2 arm study will compare the efficacy and safety of CellCept, combined with low or standard dose tacrolimus plus corticosteroids, in patients with kidney transplants. Patients will be randomized into one of 2 groups to receive either 1)CellCept 2.0g/day po bid + tacrolimus 10-12ng/mL followed by a maintenance dose of 8-10ng/mL + corticosteroids or 2)CellCept 2.0g/day po bid + tacrolimus 8-10ng/mL in the first 2 months,3-7ng/mL in month 3 followed by a maintenance dose of 3-5ng/mL + corticosteroids. The anticipated time on study treatment is 1 year, and the target sample size is 100-500 individuals.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Chronic Allograft Damage Index (CADI) Score at Month 12 After Transplantation
Time Frame: Month 12
CADI scoring was defined for 6 histological categories: interstitial inflammatory cell infiltration (0 equals (=) no or mild inflammation, 1=approximately (~)25 percent (%) cell infiltration, 2=26-50% cell infiltration, and 3=greater than (>)50% cell infiltration); interstitial fibrosis (0=none, 1=~25% interstitial affected, 2=26-50% interstitial affected, and 3=>50% interstitial affected); tubular atrophy (0=none, 1=~15% proximal tubular atrophy [PTA], 2=16-30% PTA, and 3=>30% PTA); mesangial matrix proliferation (MMP; 0=none, 1=25% non-glomerulosclerosis [NGS] combined with moderate MMP, 2=25-50% NGS combined with MMP, and 3=>50% NGS combined with MMP); glomerular sclerosis (0=none, 1=~15% glomerulus affected, 2=16-50% glomerulus affected, and 3=>50% glomerulus affected); endothelial proliferation (EP; 0=none, 1=EP to less than (<)25% remaining artery/small artery membrane [RA/SAM], 2=EP to 26-50% [RA/SAM], and 3=>50% [RA/SAM]). CADI score was the sum of the 6 histological findings.
Month 12
Glomerular Filtration Rate (GFR) at Month 12 After Transplantation
Time Frame: Month 12
GFR was determined using the Cockcroft-Gault formula to calculate the creatinine clearance, at Month 12 after renal transplantation. For males, creatinine clearance [milliliters per minute (mL/min)] = [(140 minus age) multiplied by (*) (body weight in kg) divided by [72 * serum creatinine mg per deciliter (mg/dL)]. For females, creatinine clearance (mL/min) = 0.85 * [(140 minus age) * (body weight in kg)] divided by [72 * serum creatinine (mg/dL)].
Month 12

Secondary Outcome Measures

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures.
