Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: Minimisation of TAC
Treatment with rTAC+EVR+corticosteroids
|
•EVR: Treatment started at a total daily dose of 2 mg within 24 hours after randomisation.
The dose of EVR was adjusted upon reaching trough levels (C-0h) in whole blood of 3-8 ng/mL.
The daily dose (in two administrations) of EVR may have been modified to maintain trough levels (C-0h) in whole blood of 3-8 ng/mL until Week 52 post-transplant.
•TAC: Once confirmation was obtained, beginning in Week 5, that trough levels (C-0h) in whole blood of EVR were between 3-8 ng/mL, minimisation of TAC began, in order to reach trough levels (C-0h) of TAC in whole blood of ≤5 ng/mL no later than four weeks after randomisation (Week 8), which were levels that should have been maintained until Week 52 post-transplant.
•MMF was withdrawn at the same time that EVR was introduced.
•oral corticosteroids was administered in accordance with local clinical practice, although a therapeutic strategy free of corticosteroids was permitted
|
Active Comparator: TAC + MMF + corticosteroids
Treatment with TAC + MMF + corticosteroids
|
•Dose of TAC: Trough levels (C-0h) of TAC in whole blood should have been maintained between 6-10 ng/mL until Week 52 post-transplant.
•Dose of MMF: Doses of 500-1000 mg/12 hrs was maintained until Week 52.
•Corticosteroids: During the study, oral corticosteroids was administered in accordance with local clinical practice, although a therapeutic strategy free of corticosteroids was permitted (e.g. in patients with a history of HCV).
It was recommended in any case that corticosteroids not be administered beyond Week 24 post-transplant except in cases of hepatopathy of autoimmune origin.
At each centre all patients should have followed the same administration protocol for corticosteroids based on history of HCV.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentages of Participants Showing Clinical Benefit by Renal Function Stratification
Time Frame: 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.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in Creatinine Clearance - Cockcroft-Gault Formula
Time Frame: 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. |
Screening visit (transplant), weeks 1,4,12,24,36 and 52 post-transplant
|
Changes in eGFR Based on the MDRD-4 Formula
Time Frame: 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). |
Screening visit (transplant), weeks 1,4,12,24,36 and 52 post-transplant
|
eGFR Values(MDRD-4 Formula) According to the MELD Score
Time Frame: Screening visit (transplant), weeks 1,4,12,24,36 and 52 post-transplant
|
Model for End Stage Liver Disease (MELD) score: ≤14, 15-19, 20-24, 25-29, ≥30.
The higher the number indicates the urgency for transplant.
|

Urine Protein/Creatinine Ratio
Time Frame: Screening visit, week 1,4,18,24, and 52
|
The urine protein/creatinine ratio was assessed throughout follow-up in both treatment groups.
|
Screening visit, week 1,4,18,24, and 52
|
Percentage of Participants With Incidence of Proteinuria
Time Frame: Screening visit, week 1,4,18,24, and 52
|
The incidence of proteinuria (≥0.5-0.9 g/day, ≥1.0-2.9 g/day and ≥3.0 g/day) was assessed throughout follow-up in both treatment groups.
Proteinuria was defined as protein/creatinine ratio ≥ 0.5.
|
Screening visit, week 1,4,18,24, and 52
|
Percentage of Participants With Acute Rejection, BPAR, and Treated BPAR
Time Frame: 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 administered. Loss of the liver allograft was deemed to have occurred the day that the patient was again included on the waiting list for liver transplant, the day he or she received another allograft or upon the death of the patient. All suspected hepatic allograft rejections were considered acute rejection |
Throughout the study period, approximately 2 years and 2 months
|
Time to Rejection
Time Frame: Throughout study period, approximately 2 years and 2 months
|
Time to acute rejection was calculated from the date of transplantation. Acute rejection date was taken from biopsy date, as the date of rejection was not collected. Time to treated BPAR was calculated from the date of transplantation. |
Throughout study period, approximately 2 years and 2 months
|
Severity of Rejection
Time Frame: Throughout study period, approximately 2 years and 2 months
|
Severity of acute rejection and treated BPAR was graded according to Banff criteria. Grade of acute rejection according to Banff criteria: mild, moderate, severe. |
Throughout study period, approximately 2 years and 2 months
|
Percentages of Participants With HCV-positive and HCV Genotype
Time Frame: approximately 2 years and 2 months
|
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. |
