Study Comparing the Safety and Efficacy of Belatacept With That of Cyclosporine in Patients With a Transplanted Kidney

No participant was to receive treatment for acute rejection without a biopsy to confirm the diagnosis. CSPAR=Clinically-suspected rejection, defined as an increase in serum creatinine ≥0.5 mg/dL compared with the baseline value in the absence of other factors known to adversely affect renal function, and biopsy-proven rejection, which includes all cases in which a biopsy was read by the central pathologist as demonstrating acute rejection regardless of the reason why the biopsy was performed.

BPAR includes all cases in which a biopsy read by the central pathologist demonstrates acute rejection, regardless of the reason that the biopsy was performed.

BPAR includes all cases in which a biopsy read by the central pathologist demonstrates acute rejection, regardless of the reason that the biopsy was performed. A participant was reported as having had an episode of treated acute rejection if he or she received antirejection therapy during an episode of rejection (clinically-suspected or biopsy-proven rejection).

Throughout this study, acute rejection=clinically-suspected and biopsy-proven acute rejection (BPAR). Clinically-suspected rejection is defined as an increase in serum creatinine ≥0.5 mg/dL compared with the baseline value in the absence of other factors known to adversely affect renal function. BPAR includes all cases in which a biopsy was read by the central pathologist as demonstrating acute rejection regardless of the reason why the biopsy was performed. PAR is defined as an elevation in SCr ≥0.5 mg/dL compared with the baseline value in the absence of other factors known to adversely affect renal function that led the investigator to suspect that the participant had experienced acute rejection, and in whom either the biopsy did not confirm acute rejection and the participant received treatment for acute rejection or the participant received treatment for acute rejection without a biopsy to confirm the diagnosis.

Based on postbaseline biopsies

Iohexol, a true glomerular filtration marker, is used to measure glomerular filtration rate.

Hypertension is defined as diastolic blood pressure ≥90 mm Hg and/or systolic blood pressure ≥140 mm Hg

Hypertension is defined as diastolic blood pressure ≥90 mm Hg and/or systolic blood pressure ≥140 mm Hg or, the use of any antihypertensive medication.

LDL=low-density lipoprotein; HDL=high-density lipoprotein. Total cholesterol=LDL + HDL + very low-density (VLDL) cholesterol. VLDL=triglycerides divided by 5. Non-HDL cholesterol=Total cholesterol minus HDL cholesterol.

Posttransplant diabetes mellitus is defined as the need for treatment of hyperglycemia with either an oral agent or insulin for a total of >4 weeks or hemoglobin A1c (HbA1c) >7% in a participant not known to be diabetic prior to transplantation

AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=having certain, probable, possible, or missing relationship to study drug.
