Belatacept in Renal Transplantation With Intermediate Risk Maryland Aggregate Pathology Index (MAPI) Scores

Summary

This will be a pilot study to investigate the use of belatacept (BMS) therapy in kidney transplant patients who have a MAPI score of greater than or equal to 8. The MAPI (Maryland Aggregate Pathology Index) score is a preimplantation donor scoring system which has five histopathological parameters that impact long-term kidney outcomes. Many kidney transplant recipients use calcineurin inhibitors (CNIs) as one of their anti-rejection medi cations. Kidney function may be affected by anti-rejection medications known as calcineurin inhibitors (CNIs). Sometimes CNIs can lead to toxicities and eventually loss of the kidney or episodes of chronic allograft nephropathy (CAN). Avoiding CNI immunosuppression and using belatacept therapy (BMS) instead, may be associated with improved kidney transplant outcomes.
