Brief summary

The purpose of this observational study is to examine the clinical outcomes of the use of sirolimus as base therapy in kidney allograft recipients from Expanded Criteria Donors (ECD) under conditions of routine clinical practice. The primary objective is to identify the current criteria/reasons to use sirolimus as base therapy in this selected population and define and understand the emerging patterns of immunosuppressive treatment with sirolimus.

MeasureTime frameDescription
Percentage of Participants With Main Reason for the Use of Sirolimus (Rapamune) TherapyBaselineThe study employ a questionnaire which included different clinical criteria to determine the main medical reason for the introduction of sirolimus (Rapamune) therapy after renal transplant. The physician responsible selected the one that was considered the main reason for introduction of sirolimus (Rapamune) as base immunosuppressive therapy.

Secondary

MeasureTime frameDescription
Probability of no Acute RejectionMonth 12Diagnosis of acute rejection was made via kidney biopsy. Categorization of biopsies with suspected acute rejection was based on histological findings using updated 1997 Banff criteria: Grade 1A: significant interstitial infiltration (greater than \[\>\] 25 percent \[%\] of parenchyma affected) and foci of moderate tubulitis (5-10 cells/tubular cross section), Grade 1B: significant interstitial infiltration (\>25% of parenchyma affected) and severe tubulitis (\>10 mononuclear cells/tubular cross section), Grade 2A: mild-moderate intimal arteritis, Grade 2B: severe intimal arteritis comprising \>25% of the luminal area and Grade 3: transmural arteritis and/or arterial fibrinoid change and necrosis of medial smooth muscle cells. Probability of no acute rejection throughout the sirolimus (Rapamune) therapy was estimated using Kaplan-Meier method.
Probability of Participant SurvivalMonth 12Participant's survival defined as participant living with or without a functioning graft. Probability of participant survival throughout the sirolimus (Rapamune) therapy was estimated using Kaplan-Meier method.
Average Dose of Immunosuppressive Drugs AdministeredBaseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53Immunosuppressive drugs administered included cyclosporin A (CsA) administration based on monitoring of plasma trough levels (C0), CsA administration based on monitoring of plasma levels 2-hours after CsA dose (C2), tacrolimus, and sirolimus (Rapamune).
Average Blood Level of Immunosuppressive Drugs AdministeredBaseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53Immunosuppressive drugs administered included cyclosporin A (CsA) administration based on monitoring of plasma trough levels (C0), CsA administration based on monitoring of plasma levels 2-hours after CsA dose (C2), tacrolimus, and sirolimus (Rapamune).
Average Creatinine ClearanceBaseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53Creatinine clearance (CCr) is a measure of glomerular filtration rate (GMFR), an index of kidney function. CCr is the volume of blood plasma that is cleared of creatinine by the kidneys per unit time. Normal values for healthy, young males are in the range of 100-135 milliliter per minute (mL/min) and for females, 90-125 mL/min. Creatinine clearance decreases with age. A low creatinine clearance rate indicates poor kidney function.
Average ProteinuriaBaseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53Proteinuria defined as the presence of an excess of serum proteins in the urine. Normal value of proteinuria is below 0.15 grams per 24 hours (g/24 hr).

Participants who discontinued sirolimus (Rapamune) therapy prematurely due to AE were obliged to discontinue sirolimus (Rapamune) therapy permanently, are reported.
Probability of Graft SurvivalMonth 12Graft survival was considered in participants who did not experience graft failure. Graft failure was determined by return to dialysis for a period of at least 12 weeks with no return of function, or graft loss whichever occurred sooner.

Percentage of Participants With Clinically-Significant Electrocardiogram Abnormalities

Standard 12-lead ECG was performed. ECG intervals included PR interval (time between the onset of atrial depolarization and the onset of ventricular depolarization), QRS interval (represented ventricular depolarization), QT interval (time corresponding to the beginning of depolarization to repolarization of the ventricles) corrected using Fridericia's formula (QTcF = QT divided by cube root of RR interval) and heart rate (time interval between consecutive heart beats \[RR interval\]).

Percentage of Participants With Serious Adverse Events

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

Probability of Graft Survival

Graft survival was considered in participants who did not experience graft failure. Graft failure was determined by return to dialysis for a period of at least 12 weeks with no return of function, or graft loss whichever occurred sooner.

Time frame: Month 12

Population: ITT population included all participants who were treated with Rapamune for at least 4 or 5 weeks.

Probability of no Acute Rejection

Diagnosis of acute rejection was made via kidney biopsy. Categorization of biopsies with suspected acute rejection was based on histological findings using updated 1997 Banff criteria: Grade 1A: significant interstitial infiltration (greater than \[\>\] 25 percent \[%\] of parenchyma affected) and foci of moderate tubulitis (5-10 cells/tubular cross section), Grade 1B: significant interstitial infiltration (\>25% of parenchyma affected) and severe tubulitis (\>10 mononuclear cells/tubular cross section), Grade 2A: mild-moderate intimal arteritis, Grade 2B: severe intimal arteritis comprising \>25% of the luminal area and Grade 3: transmural arteritis and/or arterial fibrinoid change and necrosis of medial smooth muscle cells. Probability of no acute rejection throughout the sirolimus (Rapamune) therapy was estimated using Kaplan-Meier method.

Time frame: Month 12

Population: ITT population included all participants who were treated with Rapamune for at least 4 or 5 weeks.
