Studies consistently show worse outcomes for black vs non-black kidney transplant recipients. At 7 yrs post-transplant in BENEFIT, bela was associated with superior graft survival and renal function vs CsA. We examined outcomes by race in BENEFIT.
Recipients of living or SCD kidneys were randomized to bela more intense (MI), bela less intense (LI), or CsA. All randomized, transplanted pts were analyzed to 7 yrs. Time to death or graft loss was compared between regimens with Cox regression. Race and treatment effect were assessed. The interaction of treatment and race was also considered. GFR was estimated from months 1–84 using a repeated measures model.
Of 666 randomized pts, 55 were black. SAE rates in black vs non-black pts were similar. In both subgroups, estimated mean GFR increased over 7 yrs for bela but declined for CsA. In black pts, GFR slopes diverged over time between bela LI and CsA (P<.0001), but not bela MI and CsA (P=.11). In non-black pts, the interaction of the treatment vs time effect deriving from the model favored each bela regimen vs CsA (P<.0001).
In this post-hoc analysis, outcomes were similar in bela-treated black and non-black pts. While estimated mean GFR was higher in black pts treated with bela vs CsA, the number of black pts was small.
|Bela MI||Bela LI||CsA||Bela MI||Bela LI||CsA|
|Pts evaluable for death/graft loss at month 84, n/N||9/15||17/23||11/17||144/204||146/203||120/204|
|Estimated mean GFR at month 84, mL/min/1.73 m2||65.1||82.3||41.5||70.6||71.0||45.2|
