Clinical Trial Summary

The 12 Month Core Study (CRAD001A1202) was designed to evaluate the efficacy and safety comparing concentration-controlled everolimus (1.5 mg/day starting dose) with reduced dose cyclosporine and corticosteroids versus 2 g/day mycophenolate mofetil (MMF) with standard dose cyclosporine and corticosteroids in de novo renal transplant recipients.

Extension Study (CRAD001A1202E1): Until 24 months after renal transplantation, the study was designed to evaluate the long-term safety and efficacy comparing concentration-controlled everolimus with reduced dose cyclosporine (Neoral®) and corticosteroids versus mycophenolate mofetil with standard dose Neoral® and corticosteroids in de novo renal transplant recipients. Beyond 24 months after renal transplantation, the study was designed to provide everolimus treatment for patients in everolimus group until everolimus is approved and marketed in Japan.

Related Conditions & MeSH terms

• Kidney Transplantation

Intervention

Drug:
• Everolimus
0.75 mg twice daily, trough level adjusting between 3 and 8 ng/ml.
• Mycophenolate mofetil (MMF)
The initial dose of 2 gm/day Mycophenolate mofetil was started within 24-36 hours from reperfusion after transplantation. MMF was administered daily for 12 months in the core study and 12 months in the extension study.
• Basiliximab
Patients received first dose of basiliximab (20 mg) 2 hours prior to transplantation and 20 mg at Day 4 or according to local practice

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Core Study: Number of Patients With Composite Efficacy Endpoint	The composite efficacy endpoint consisted of treated biopsy proven acute rejection (BPAR) episodes, graft loss, death or loss to follow-up. A treated BPAR was defined as a biopsy graded IA, IB, IIA, IIB, or III and which was treated with anti-rejection therapy. The allograft was presumed to be lost on the day the patient starts dialysis and was not able to stop dialysis. If the patient underwent a graft nephrectomy, then the day of nephrectomy was considered as the day of graft loss.; For the individual components (including loss of follow-up)of the composite endpoint, patients are counted for the first event to occur.	12 months	No
Primary	Extension Study: Renal Function Measured by Calculated Glomerular Filtration Rate (cGFR) Using the Modification of Diet in Renal Disease (MDRD) Formula	Renal function was assessed by glomerular filtration rate (GFR) using the MDRD formula: GFR [mL/min/1.73m2] = 186.3*(C-1.154)*(A-0.203)*G*R C is the serum concentration of creatinine [mg/dL] A is age [years] G = 0.742 when gender is female, otherwise G=1 R = 1.21 when race is black, otherwise R=1; Loss to follow up (in In Primary Core Outcome Measure) is composite efficacy failure and contains incidence of treated BPAR, graft loss, death or loss to follow-up	Month 24	No
Primary	Extension Study: Renal Function Measured by Calculated Glomerular Filtration Rate (cGFR) Using the Modification of Diet in Renal Disease (MDRD) Formula	Renal function was assessed by glomerular filtration rate (GFR) using the MDRD formula: GFR [mL/min/1.73m2] = 186.3*(C-1.154)*(A-0.203)*G*R C is the serum concentration of creatinine [mg/dL] A is age [years] G = 0.742 when gender is female, otherwise G=1 R = 1.21 when race is black, otherwise R=1	Month 48	No
Secondary	Core Study: Number Participants With Combined Graft Loss, Death or Loss to Follow-up	The allograft was presumed to be lost on the day the patient starts dialysis and was not able to stop dialysis. If the patient underwent a graft nephrectomy, then the day of nephrectomy was considered as the day of graft loss.; A loss to follow-up in graft loss, death or loss to follow-up is a patient who did not experience graft loss or death and whose last day of contact was prior to Day 316, i.e. prior to the Month 12 visit window.	12 months	No
Secondary	Core Study: Renal Function Measured by Calculated Glomerular Filtration Rate (cGFR) Using Modification of Diet in Renal Disease (MDRD) Formula	Modification of Diet in Renal Disease (MDRD) formula is: Calculated 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	Month 12	No
Secondary	Extension Study: Number of Participants With Combined Efficacy Endpoint: Graft Loss, Death, Loss to Follow-up and/or Treated Biopsy Proven Acute Rejection (BPAR)	Graft loss was defined as the day the patient started dialysis and was not able to subsequently be removed from dialysis or re-transplant.; Loss-to-follow was a patient who did not experience a treated BPAR, graft loss or death and whose last day of contact was prior to Month 24.; A Graft Biopsy was done within 48 hours of suspect rejection. Biopsies were read by the local pathologist according to the updated Banff '97 criteria.; Treated BPAR was based on local laboratory biopsy results and was defined as a biopsy Banff criteria graded IA to III that was treated with anti-rejection therapy.	24 Months	No
Secondary	Extension Study: Renal Function Measured by Calculated Glomerular Filtration Rate (GFR) Using the Nankivell Formula	The Nankivell formula was used to calculate GFR at Month 24: GFR[mL/min]=6.7/C + W/4 - UREA/2 - 100/H^2 + 35 (25 for females) W= body weight [kg] H= height [m] C= serum creatinine [mmol/L] UREA= serum urea [mmol\L]	Month 24, Month 48	No
