简要总结
This study is designed to determine the safety and efficacy of two calcineurin inhibitor free treatment groups 1) a belatacept, everolimus and early corticosteroid withdrawal (ECSWD) immunosuppressive regimen with rabbit antithymocyte globulin induction (rATG) and 2) a belatacept, mycophenolate, chronic steroid regimen with rATG and compare to historical controls of tacrolimus-based and belatacept-based regimens in combination with rATG induction, mycophenolate, and ESWD in renal transplant recipients.
The purpose is to evaluate the effect of 2 regimens (rATG induction/belatacept/everolimus/ESWD and rATG induction/belatacept/mycophenolate/CS) on the composite of patient death, graft loss, or eGFR (MDRD) < 45 mL/min/1.73m2 at Month 12 post-transplantation compared to historical controls of the BEST Trial (groups B and C).
详细描述
The BETTER trial is designed to determine the safety and efficacy of two calcineurin inhibitor free treatment groups 1) a belatacept, everolimus and early corticosteroid withdrawal (ESWD) immunosuppressive regimen with rabbit antithymocyte globulin induction (rATG) and 2) a belatacept, mycophenolate, chronic steroid regimen with rATG and compare to historical controls of tacrolimus-based and belatacept-based regimens in combination with rATG induction, mycophenolate, and ESWD in renal transplant recipients.
Study Hypotheses
- A belatacept-based immunosuppressive regimen with rATG induction, everolimus and ESWD in renal transplant recipients will lead to less risk of graft loss, patient death, or eGFR <45ml/min/1.73m2 at 12 and 24 months as compared to a tacrolimus-based immunosuppressive regimen with rATG, mycophenolate, and ESWD in renal transplant recipients (historical control from the BEST Trial-Group C).
- A belatacept-based immunosuppressive regimen with rATG induction, everolimus and ESWD in renal transplant recipients will lead to less risk of graft loss, patient death, or eGFR <45ml/min/1.73m2 at 12 and 24 months as compared to a belatacept-based immunosuppressive regimen with rATG and mycophenolate, and ESWD in renal transplant recipients (historical control from the BEST Trial-Group B).
- A belatacept-based immunosuppressive regimen with rATG, mycophenolate and CS in renal transplant recipients will lead to less risk of graft loss, patient death, or eGFR <45ml/min/1.73m2 at 12 and 24 months as compared to a tacrolimus-based immunosuppressive regimen with rATG, mycophenolate, and ESWD in renal transplant recipients (historical control from the BEST Trial-Group C).
- A belatacept-based immunosuppressive regimen with rATG induction, mycophenolate and CS in renal transplant recipients will lead to less risk of graft loss, patient death, or eGFR <45ml/min/1.73m2 at 12 and 24 months as compared to a belatacept-based immunosuppressive regimen with rATG, mycophenolate, and ESWD in renal transplant recipients (historical control from the BEST Trial-Group B).
A controlled, randomized group study is accepted in renal transplantation to evaluate new immunosuppressive regimens versus the current standard of care. Although the ideal study would employ a blinded methodology with a simultaneous control group to minimize bias, the study will not be blinded and evaluates a historical control groups conducted in similar centers.
To allow comparison between studies, the primary composite endpoint of death, graft loss, or eGFR <45ml/min/1.73m2 will be analyzed similarly. The secondary and tertiary endpoints are the similar as well.
