Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Patient Incidence of Biopsy-confirmed Acute Rejection (BCAR) at 6 Months
Délai: 6 months

A BCAR is a suspected new rejection w/in 6 mos. of skin closure, confirmed by Banff Grade ≥1A assigned by a pathologist. The Banff 97 classification system is used for interpreting histology of allograft biopsies, including Mild (1A/1B), Moderate (2A/2B) & Severe (3).

Kaplan Meier analysis was used to estimate % of pts. w/event. Patients w/no event at time of scheduled visit or whose 1st event was after premature discontinuation of study drug/tacrolimus were censored on the scheduled day of a) assessment, b) of premature treatment discontinuation or c) last evaluation, whichever came 1st.

Description de la mesure
Délai
Overall Patient Incidence of BCAR
Délai: End of Study (36 months)

Overall patient incidence of BCAR is defined as a suspected new rejection at any time following skin closure confirmed by a Banff Grade ≥ 1A as assigned by a local pathologist. Incidence is reported as the percentage of patients with BCAR. The Banff 97 scale is a classification system for interpreting histology of allograft biopsies. The grades range from Mild (1A & 1B) to Moderate (2A & 2B) to Severe (3).

End of Study was defined as the last day of evaluation and could have included bivariate assessments after 36 months.
End of Study (36 months)
Efficacy Failure
Délai: End of Study (36 months)

Efficacy Failure is a composite measure of biopsy confirmed acute rejection, graft loss and death. Data is reported as the percentage of patients with Efficacy Failure.

End of Study was defined as the last day of evaluation and could have included bivariate assessments after 36 months.
End of Study (36 months)
Clinically Treated Acute Rejection
Délai: End of Study (36 months)

Clinically treated acute rejection is defined as patient incidence of any rejection (suspected or otherwise) for which treatment was provided. Data is reported as the percentage of patients with Clinically Treated Acute Rejection.

End of Study was defined as the last day of evaluation and could have included bivariate assessments after 36 months.
End of Study (36 months)
Time to First BCAR
Délai: End of Study (36 months)

Time to first BCAR is defined as the number of days from skin closure to the first episode of BCAR.

End of Study was defined as the last day of evaluation and could have included bivariate assessments after 36 months.
End of Study (36 months)
Graft Survival at 12 Months
Délai: 12 months

Graft survival is defined as no graft loss (re-transplant, return to dialysis for more than 30 days or death) with 12 months of skin closure.

Kaplan Meier analysis was used to estimate percentage of patients with event. Patients with no event by the time of the scheduled visit or whose first event was after premature discontinuation of randomized study drug or tacrolimus were censored on the scheduled day of assessment, on the day of premature treatment discontinuation or last evaluation day, whichever came first.
12 months
Overall Graft Survival
Délai: End of Study (36 months)

Overall graft survival is defined as not having graft loss (re-transplant, return to dialysis for more than 30 consecutive days, or death) at any time following skin closure. Data is reported as the percentage of patients with Overall Graft Survival.

End of Study was defined as the last day of evaluation and could have included bivariate assessments after 36 months.
End of Study (36 months)
Patient Survival at 12 Months
Délai: 12 months

Patient survival is defined as not dead within 12 months after skin closure.

Kaplan Meier analysis was used to estimate percentage of patients with event. Patients with no event by the time of the scheduled visit or whose first event was after premature discontinuation of randomized study drug or tacrolimus were censored on the scheduled day of assessment, on the day of premature treatment discontinuation or last evaluation day, whichever came first.
12 months
Overall Patient Survival
Délai: End of Study (36 months)

Overall patient survival is defined as not dead at any time following skin closure. Data is reported as the percentage of patients with Overall Patient Survival.

End of Study was defined as the last day of evaluation and could have included bivariate assessments after 36 months.
End of Study (36 months)
Renal Function Abnormalities Based on Creatinine Clearance
Délai: 1 month and End of Study (36 months)

Increases in creatinine clearance usually indicates an improvement.

Change in creatinine clearance from month 1 was calculated.

Change from 1 month is calculated by month 36 - month 1.
1 month and End of Study (36 months)
Renal Function Abnormalities Based on Serum Creatinine
Délai: 1 month and End of Study (36 months)

Decrease in serum creatinine usually indicates an improvement.

Change in creatinine clearance from month 1 was calculated.

Change from 1 month is calculated by month 36 - month 1.
1 month and End of Study (36 months)
