A Study to Evaluate the Efficacy and Safety of Zenapax in Combination With CellCept, Cyclosporine, and Corticosteroids in Patients Undergoing Cardiac Transplantation

The acute rejection episode was a composite end-point of acute rejection and treatment failure within 6 months. Participants with acute rejection included participants with a biopsy histology of ISHLT Grade IIIA, IIIB, or IV and participants with hemodynamic compromise (HDC) who were treated for acute rejection (whether or not a biopsy was done and regardless of the grade of the biopsy). Participants who had treatment failure included participants who died within 6 months of transplantation before experiencing acute rejection or who were re-transplanted within 6 months of the primary transplantation and who did not experience an acute rejection or who were lost to follow-up

The number of participants with 0,1, 2, 3 or 4 episodes at 6 and 12 months PT were reported. An episode of acute rejection was defined according to the date of positive biopsy of Grade IIIA or worse or the date of start of treatment for HDC, whichever came first.

The survival of the graft and participants at 6,12 months and 3 years PT was reported

The number of participants with Worst International Society of Heart and Lung Transplant (ISHLT) grade within first 6 months and 12 months PT were reported. ISHLT is a standardized grading method to determine the acute cellular rejection on endomyocardial biopsy ; where 0= no rejection, IA= focal (perivascular or interstitial) infiltrate without necrosis, IB= diffuse but sparse infiltrate without necrosis, II=one focus only with aggressive infiltration and/or focal myocyte damage, IIIA=multifocal aggressive infiltrates and/or myocyte damage, IIIB= diffuse inflammatory process with necrosis, IV= diffuse aggressive polymorphous and/or infiltrate and/or edema and/or hemorrhage and/or vasculitis, with necrosis

The median time to first acute rejection episode within first 6 months and 12 months PT was reported.

The number of participants who received monomurab Cluster of differentiation 3, orthoclone, polyclonal antithymocyte globulin or antilymphocyte globulin for treatment of biopsy proven rejection or HDC within 6 and 12 months PT were reported.

The maintenance doses of mycophenolate mofetil (1.5g twice a day daily), cyclosporine (1-4 mg/kg IV or 2-6 mg/kg oral [PO]/nasogastric [NG] within 72 hours post-operative]), and cumulative dose of corticosteroids (500-1000 mg IV methylprednisolone pre-operative switched to oral at 0.5-1 mg/kg/day. Tapered to 0.2 mg/kg/d by Day 28, 0.1-0.15 mg/kg/day from Days 36 to 90, and 0.1-0.15 mg/kg/day from Days 120 to 180)at 6 and 12 months PT were reported. Maintenance dose was calculated as total dose per day summed over all days that a participant was administered drug within the specified time interval, divided by number of days that a participant took drug within that time interval.

Lipid profile included total cholesterol, low density lipoproteins (LDL), high density lipoproteins (HDL), and triglycerides (all total cholesterol, LDL, HDL, and triglycerides with unit milligram per decilitre [mg/dL]), were reported. The median change from baseline (Day -2) in lipid profile values at 3 months and 6 months was reported.

A marked reference range was predefined by Roche. The marked reference range is broader than the standard reference range. Values falling outside the marked reference range (low or high) that also represent a defined change from Baseline were considered marked laboratory abnormalities (i.e. potentially clinically relevant). Hematology included hemoglobin, hematocrit, white blood cell count (WBC) with differential (including granulocytes or neutrophils, basophils, eosinophils, monocytes, lymphocytes), platelets, and erythrocyte count

A marked reference range was predefined by Roche. The marked reference range is broader than the standard reference range. Values falling outside the marked reference range (low or high) that also represent a defined change from Baseline were considered marked laboratory abnormalities (i.e. potentially clinically relevant). Biochemistry included blood urea nitrogen, creatinine, serum glutamic oxalacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), gamma-glutamyl transferase (GGT), phosphorous, total bilirubin, direct bilirubin, total protein, albumin, glucose, alkaline phosphatase, low density lipoprotein (LDH), uric acid, carbon dioxide, magnesium, sodium, potassium, chloride, calcium, LDL, HDL, total cholesterol, and triglycerides.

An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Pre-existing conditions which worsened during this study were reported as AEs. A serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.

The opportunistic infections included infections with Cytomegalovirus, Aspergillus, Candida, Pneumocystis, Cryptococcus, Listeria, Herpes simplex, Herpes zoster. For malignancy, participants with any type of malignancy whose date of onset or diagnosis was after randomization was reported.
