Study Of The Safety And Efficacy Of Conversion From A CNI To Sirolimus In Renally-Impaired Heart Transplant Recipients

Creatinine Clearance (CC) calculated using Cockcroft-Gault equation, adjusted for body surface area. Calculated CC: method to approximate kidney function. It measures rate creatinine (substance formed from metabolism of creatine) is cleared from blood by kidneys. Normal adult creatinine clearance is greater than or equal to (≥) 90 milliliters per minute per 1.73 meters squared (mL/min/1.73m^2). Change from baseline=CC at Week 52 minus CC at baseline where higher scores represented improved renal function; Least squares mean adjusted for baseline calculated creatinine clearance and center.

Creatinine clearance at baseline calculated using Cockcroft-Gault equation and adjusted for body surface area. Calculated CC: method to approximate kidney function. It measures rate creatinine (substance formed from metabolism of creatine) is cleared from blood by kidneys. Normal adult creatinine clearance is ≥ 90 mL/min/1.73m^2.

It measures rate creatinine (substance formed from metabolism of creatine) is cleared from blood by kidneys. Normal adult creatinine clearance is ≥ 90 mL/min/1.73m^2. Change from baseline=CC at Week X minus CC at baseline where higher scores represented improved renal function; Least squares mean adjusted for baseline calculated creatinine clearance and center.

Creatinine clearance calculated using MDRD equation. Normal adult creatinine clearance is ≥ 90 mL/min/1.73m^2. Change from baseline=CC at Week X minus CC at baseline where higher scores represented improved renal function. Least squares mean adjusted for baseline calculated creatinine clearance (MDRD) and center.

Serum creatinine is an indicator of kidney function. Creatinine is a substance formed from the metabolism of creatine, commonly found in blood, urine, and muscle tissue. It is removed from the blood by the kidneys and excreted in urine. Normal adult blood levels of creatinine=45 to 90 micromoles per liter (mcmol/L) for females, 60 to 110 mcmol/L for males, however normal values are age-dependent. Change from baseline=creatinine level at Week x minus baseline level where higher scores represented decreased kidney function. Least squares mean adjusted for treatment group and center.

The change in creatinine clearance over time assessed using the random coefficient slope of the regression line with creatinine clearance as the dependent variable and study day as the independent variable. Time points calculated as study days, relative to time of randomization of study medication. Observed data multiplied by a scale factor of 365 to express an annual change.

Survival time from the start of study treatment to date of death due to any cause, censored at the last visit if no death. Death was determined from the Death report. The distribution of time to death was to be estimated using Kaplan-Meier method and compared between treatment groups with a proportional hazard model. The number and percent of survival at 6 and 12 months were to be reported.

Based on International Society for Heart and Lung Transplantation [ISHLT] 1990 criteria: rejections Grade 3A or higher, rejection accompanied by hemodynamic compromise or requiring treatment. Grade 3A or higher included: multifocal aggressive infiltrates and/or myocyte damage, diffuse inflammatory process with necrosis, diffuse aggressive polymorphus with necrosis, increased infiltrates, and changes in edema, hemorrhage, or vasculitis. Biopsies performed for clinically suspected rejection (for cause), site's standard of care (site protocol biopsy), or protocol mandated.

Severity of acute rejection summarized using revised 2005 ISHLT criteria. Grade 0R: no rejection, Grade 1R: Focal (perivascular or interstitial) infiltrate without necrosis, diffuse but sparse infiltrate without necrosis, or one focus only with aggressive infiltration and/or focal myocyte damage, Grade 2R:Multifocal aggressive infiltrates and/or myocyte damage, and Grade 3R:Diffuse inflammatory process with necrosis, or diffuse aggressive polymorphous with necrosis, increased infiltrate, changes in edema, hemorrhage and vasculitis.

Time from baseline to first biopsy-confirmed acute rejection defined as any of the following (based on ISHLT 1990 criteria): all rejections Grade 3A or higher, any rejection accompanied by hemodynamic compromise, or any rejection requiring treatment. ISHLT Grade 3A or higher included: Multifocal aggressive infiltrates and/or myocyte damage, diffuse inflammatory process with necrosis, diffuse aggressive polymorphus with necrosis, increased infiltrates, and changes in edema, hemorrhage, or vasculitis.

Number of participants requiring antilymphocyte antibody therapy with suspected or biopsy-proven, steroid-resistant, acute rejection with or without hemodynamic compromise. Acute rejection based on ISHLT 1990 criteria: all rejections Grade 3A or higher, any rejection accompanied by hemodynamic compromise, or any rejection requiring treatment. ISHLT Grade 3A or higher included: Multifocal aggressive infiltrates and/or myocyte damage, diffuse inflammatory process with necrosis, diffuse aggressive polymorphus with necrosis, increased infiltrates, and changes in edema, hemorrhage, or vasculitis.
