Percentages of Participants Showing Clinical Benefit by Renal Function StratificationPrimary· week 4, week 52.
Clinical benefit is defined as: • an improvement in 1 or 2 ranges of the eGFR, according to MDRD-4 at Week 52 post-transplant in patients with values of 30-\<45 or 45-\<60 mL/min/1.73 m2 in Week 4. or • stabilisation of eGFR in patients with values ≥60 mL/min/1.73 m2 at Week 4 and maintained at Week 52 post-transplant.

Changes in Creatinine Clearance - Cockcroft-Gault FormulaSecondary· Screening visit (transplant), weeks 1,4,12,24,36 and 52 post-transplant
Kidney function was assessed over time by creatine clearance based on the Cockcroft-Gault formula.
Estimated creatinine clearance (mL/min) = \[(140 - age) x (weight) x (0.85 if female)\] / (72 x serum creatinine).
Units: age (years); weight (kg); serum creatinine (mg/dL). The values of the eGFR according to the creatinine clearance (Cockcroft-Gault formula) for the ITT population were ml/min/1.73 m\^2.

Changes in eGFR Based on the MDRD-4 FormulaSecondary· Screening visit (transplant), weeks 1,4,12,24,36 and 52 post-transplant
Kidney function was assessed over time by changes in eGFR according to the MDRD-4 formula. The MDRD-4 formula (Levey et al., 2000) was used based on serum concentration of creatinine (conventional units): eGFR (mL/min/1.73 m2) = 186 x (serum creatinine)-1.154 x (age)-0.203 x (0.742 if female) x (1.210 if of African descent).
Units: serum creatinine (mg/dL); age (years).

Percentage of Participants With Acute Rejection, BPAR, and Treated BPARSecondary· Throughout the study period, approximately 2 years and 2 months
Liver biopsy had to be performed in all cases where acute rejection was suspected. Results of the biopsy were interpreted by the local pathologist (who did not known the treatment given to the patient) according to the Banff classification (1997).
Biopsy-proven acute rejection (BPAR) defined as clinical suspicion of acute rejection confirmed in biopsy.
Treated BPAR was deemed to be an episode of acute rejection in which the interpretation of the local pathologist showed that it reached any grade of acute rejection under the Banff classification, and for which anti-rejection therapy was admin

The viral load of HCV-RNA and HCV genotype was assessed in HCV-positive patients.
The term "genotype" was used to describe strains of HCV that vary but were related to the virus. Worldwide, there were 11 primary groups of HCV genotypes designated by the numbers from 1-11, with the most common in our setting being subtypes 1a, 1b, 2 and 3, which were identified in the local laboratory according to their usual testing methods.

Adverse events — posted to ClinicalTrials.gov
Time frame: Adverse Events (AEs) are collected from First Patient First Visit (FPFV) until Last Patient Last Visit (LPLV). All AEs reported in this record are from date of First Patient First Treatment until Last Patient Last Visit) up to approximately 2 years and 2 month..
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
Assuming greater efficacy in the prevention of acute rejection in the EVR arm with minimisation of TAC levels, the hypothesis of the present trial was that the introduction of EVR in combination with the minimisation of TAC (rTAC) may offer improved kidney function compared with standard therapy with TAC-MMF.
