Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Low-dose Everolimus Group<br>1.5 mg everolimus (one 0.75-mg tablet bis in diem/twice a day (bid)) + basiliximab + reduced-dose Cyclosporine A (CsA) ± corticosteroids. The CsA dose was adjusted to attain a trough (C0) value within the pre-specified target ranges: starting at the day 5 visit: 100-200 ng/mL, starting at the month 2 visit: 75-150 ng/mL, starting at the month 4 visit: 50-100 ng/mL and starting at the month 6 visit: 25-50 ng/mL. Patients received their first dose of basiliximab within 2 hours prior to transplant surgery and on day 4 post-transplant or according to local practice. Corticosteroids were administered according to local therapy. | Drug: Everolimus<br>* oral, bis in diem/twice a day (bid)<br>* Other names: Certican, Zotress;Drug: Cyclosporine A (CsA)<br>* CsA dose adjustments were based on CsA trough levels (C0).<br>* Other names: Neoral;Drug: Basiliximab<br>* All patients received two 20 mg doses of basiliximab administered intravenously. The first dose was to be given within 2 hours prior to transplant surgery and the second dose was to be administered on day 4, or each dose could have been administered according to local practice.<br>* Other names: Simulect;Drug: Corticosteroids<br>* Oral corticosteroids were administered according to local practice during the trial. At the same center, all patients were to follow the same steroid administration protocol.<br>|
| Experimental: High-dose Everolimus Group<br>3.0 mg everolimus (two 0.75-mg tablets bid) + basiliximab + reduced-dose CsA ± corticosteroids. The CsA dose was adjusted to attain a trough (C0) value within the pre-specified target ranges: starting at the day 5 visit: 100-200 ng/mL, starting at the month 2 visit: 75-150 ng/mL, starting at the month 4 visit: 50-100 ng/mL and starting at the month 6 visit: 25-50 ng/mL. Patients received their first dose of basiliximab within 2 hours prior to transplant surgery and on day 4 post-transplant or according to local practice. Corticosteroids were administered according to local therapy. | Drug: Everolimus<br>* oral, bis in diem/twice a day (bid)<br>* Other names: Certican, Zotress;Drug: Cyclosporine A (CsA)<br>* CsA dose adjustments were based on CsA trough levels (C0).<br>* Other names: Neoral;Drug: Basiliximab<br>* All patients received two 20 mg doses of basiliximab administered intravenously.

At the same center, all patients were to follow the same steroid administration protocol.<br>|
| Active Comparator: Control Group<br>1.44 g Mycophenolic Acid (two 360-mg tablets bid) + basiliximab + standard-dose CsA ± corticosteroids. The CsA dose was adjusted to attain a C0 value within the following range for the time of the study: starting at the day 5 visit: 200-300 ng/mL, starting at the month 2 visit and thereafter: 100-250 ng/mL. Patients received their first dose of basiliximab within 2 hours prior to transplant surgery and on day 4 post-transplant or according to local practice. Corticosteroids were administered according to local therapy. | Drug: Mycophenolic Acid (MPA)<br>* 2 oral capsules of mycophenolic acid 360mg administered bid<br>* Other names: Myfortic;Drug: Cyclosporine A (CsA)<br>* CsA dose adjustments were based on CsA trough levels (C0).<br>* Other names: Neoral;Drug: Basiliximab<br>* All patients received two 20 mg doses of basiliximab administered intravenously. The first dose was to be given within 2 hours prior to transplant surgery and the second dose was to be administered on day 4, or each dose could have been administered according to local practice.<br>* Other names: Simulect;Drug: Corticosteroids<br>* Oral corticosteroids were administered according to local practice during the trial.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Composite Efficacy Endpoints - 12 Month Analysis | The primary efficacy endpoint was the 12 month analysis of primary efficacy failure defined as a composite endpoint including treated biopsy proven acute rejection (BPAR), graft loss, death or loss to follow-up. A treated BPAR episode was defined as a biopsy graded IA, IB, IIA, IIB, or III that was treated with anti-rejection therapy. Graft loss was defined as the allograft was presumed to be lost on the day the patient started dialysis and was not able to subsequently be removed from dialysis as well as re-transplant. | 12 months | 
| Non-inferiority Analysis on Percentage of Participants With Composite Efficacy Endpoints | The primary efficacy endpoint was the 12 month analysis of primary efficacy failure defined as a composite endpoint including treated biopsy proven acute rejection (BPAR), graft loss, death or loss to follow-up. In the definition of composite efficacy failure, loss to follow-up includes patients who did not experience treated BPAR, graft loss or death on or after day 1 and whose last day of contact was prior to day 316, the start day of the 12 month visit window. | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With the Composite Incidence of Graft Loss, Death or Loss to Follow up at 12 Months Post-transplantation | Graft loss was defined as graft loss (the allograft was presumed to be lost on the day the patient started dialysis and was not able to subsequently be removed from dialysis) and re-transplant. A loss to follow-up patient in the composite endpoint of graft loss, death or loss to follow-up (the main secondary efficacy endpoint) was a patient who did not experience graft loss or death from day 1 and whose last day of contact was prior to study day 316. | 12 months | 
| Non-inferiority Analysis of Renal Function, Calculated by Glomerular Filtration Rate (cGFR) Using Modification of Diet in Renal Disease (MDRD) Formula | Modification of Diet in Renal Disease (MDRD) formula is: GFR [mL/min/1.73m^2] = 186.3*(C^-1.154)*(A^-0.203)*G*R where C is the serum concentration of creatinine [mg/dL], A is patient age at sample collection date [years], G=0.742 when gender is female, otherwise G=1, R=1.21 when race is black, otherwise R=1 | at 12 months |
