What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Main Reason for the Use of Sirolimus (Rapamune) Therapy

    The 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.

    Measured: Baseline

Secondary outcomes (20)
  1. 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.

    Measured: Month 12

  2. 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.

    Measured: Month 12

  3. Probability of Participant Survival

    Participant'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.

    Measured: Month 12

  4. Average Dose of Immunosuppressive Drugs Administered

    Immunosuppressive 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).

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  5. Average Blood Level of Immunosuppressive Drugs Administered

    Immunosuppressive 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).

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  6. Average Creatinine Clearance

    Creatinine 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.

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  7. Average Proteinuria

    Proteinuria 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).

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  8. Percentage of Participants Who Prematurely Discontinued the Sirolimus (Rapamune) Therapy

    Measured: Baseline up to Month 12

  9. Percentage of Participants Who Prematurely Discontinued the Sirolimus (Rapamune) Therapy Due to Inefficacy

    Measured: Baseline up to Month 12

  10. Percentage of Participants Who Prematurely Discontinued the Sirolimus (Rapamune) Therapy Due to Adverse Events

    An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who received study drug. A serious adverse event (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. Participants who discontinued sirolimus (Rapamune) therapy prematurely due to AE were obliged to discontinue sirolimus (Rapamune) therapy permanently, are reported.

    Measured: Baseline up to Month 12

  11. Body Mass Index

    BMI was calculated as weight divided by height squared and measured as kilogram per square meter (kg/m^2).

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  12. Number of Participants With Body Temperature

    Body temperature was measured in degree Celsius. Each participants were classified into three different categories based on their body temperature: body temperature less than 35 degree Celsius = hypothermia, body temperature between 35 to 37.5 degree Celsius = feverless, and body temperature greater than 37.5 degree Celsius = fever.

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  13. Blood Pressure

    Systolic and diastolic blood pressure (BP) was measured after the participant had rested in the supine position for at least 5 minutes with the participant's arm supported at the level of the heart, and recorded to the nearest millimeters of mercury (mmHg).

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  14. Pulse Rate

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  15. Body Weight

    Measured: Baseline, Week 1 or 2, 4 or 5, 12 or 13, 24 or 25, 52 or 53

  16. Percentage of Participants With Physical Abnormalities

    Physical abnormalities included all the abnormalities related to general disorders and administration site conditions, gastrointestinal disorders, skin and subcutaneous tissue disorders, vascular disorders, investigations, infections and infestations, eye disorders, respiratory, thoracic and mediastinal disorders, nervous system disorders, musculoskeletal and connective tissue disorders, injury, poisoning and procedural complications, surgical and medical procedures, psychiatric disorders, neoplasms benign, malignant and unspecified (incl cysts and polyps), ear and labyrinth disorders, and congenital, familial and genetic disorders.

    Measured: Baseline up to Month 12

  17. Percentage of Participants With Adverse Events

    An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug.

    Measured: Baseline up to Month 12

  18. 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.

    Measured: Baseline up to Month 12

  19. 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]).
