简要总结
The purpose of this study is to learn if conversion to belatacept from cyclosporine or tacrolimus will preserve kidney function in people who have had a kidney transplant. The safety and tolerability of this treatment will also be studied

结局指标
主要结局
Mean Change From Baseline in Calculated Glomerular Filtration Rate (GFR) With Imputed Values to 12 Months Post Randomization - All Randomized Participants (Intent-to-Treat Population)
时间窗: Baseline to 12 months post randomization
Calculated GFR assessment used the modification of diet in renal disease (MDRD) formula. GFR was measured as mL/min/1.73 m\^2. For death or graft loss participants, calculated GFR (cGFR) value 10 was used, for other participants who had a post baseline cGFR value missing, but had baseline value and at least 2 post baseline values available, which were at least 120 days apart, linear regression model was used to impute the cGFR value. Baseline = value at screening. Randomization/First Dose was on Day 1.
