Optimization of NULOJIX® Usage Towards Minimizing CNI Exposure in Simultaneous Pancreas and Kidney Transplantation

eGFR was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI):

• A score of ≥90 means kidney function is normal.
• A score between 60 and 89 indicates mildly reduced kidney function, pointing to kidney disease.
• Scores between 30 and 59 indicates moderately reduced kidney function.
• Scores between 15 and 29 indicate severely reduced kidney function.
• Scores below 15 indicate very severe or end stage kidney failure.

The stages of Chronic Kidney Disease are defined using the participant's GFR value:

• Stage 1 if GFR value is ≥90 ( kidney function is normal)
• Stage 2 if 60 ≤ GFR < 90 (mildly reduced kidney function, pointing to kidney disease)
• Stage 3A if 45 ≤ GFR < 60*
• Stage 3B if 30 ≤ GFR < 45*
• Stage 4 if 15 ≤ GFR < 30 (severely reduced kidney function)
• Stage 5 if GFR < 15 (severe or end stage kidney failure).

Stages 3A and 3B indicate moderately reduced kidney function.*

The stages of Chronic Kidney Disease (CKD) are defined using the participant's GFR value:

• Stage 1 if GFR value is ≥ 90 (kidney function is normal)
• Stage 2 if 60 ≤ GFR < 90 (mildly reduced kidney function, pointing to kidney disease)
• Stage 3A if 45 <= GFR < 60*
• Stage 3B if 30 <= GFR < 45*
• Stage 4 if 15 ≤ GFR < 30 (severely reduced kidney function)
• Stage 5 if GFR < 15 (severe or end stage kidney failure).

Stages 3A abd 3B indicate moderately reduced kidney function.*

The estimated Glomerular Filtration Rate (eGFR) was calculated using the Modification of Diet in Renal Disease equation (MDRD):

• A score of ≥ 90 means kidney function is normal.
• A score between 60 and 89 indicates mildly reduced kidney function, pointing to kidney disease.
• Scores between 30 and 59 indicates moderately reduced kidney function.
• Scores between 15 and 29 indicate severely reduced kidney function.
• Scores below 15 indicate severe or endstage kidney failure.

• A score of ≥ 90 means kidney function is normal.
• A score between 60 and 89 indicates mildly reduced kidney function, pointing to kidney disease.
• Scores between 30 and 59 indicates moderately reduced kidney function.
• Scores between 15 and 29 indicate severely reduced kidney function.
• Scores below 15 indicate very severe or endstage kidney failure.

An estimate of the slope, or change over time, in eGFR was produced using standard statistical linear modeling procedures. The estimate was then re-scaled so that it could be interpreted as a change in eGFR per month. Positive numbers indicate increasing kidney function.

Larger numbers indicate greater change in kidney function.

Participants achieved successful discontinuation if they were able to discontinue (e.g., off tacrolimus therapy completely) over a 4-8 weeks after tacrolimus withdrawal was initiated at week 40.

Delayed grafted function is defined as dialysis in the first week on one or more occasions for any indication other than the treatment of acute hyperkalemia in the setting of otherwise acceptable renal function.

Participants with full pancreatic graft functions are defined as those that no longer require exogenous insulin therapy.

C-peptide is a measure of pancreatic function. The definition of partial pancreatic graft function: a fasting C-peptide levels >0.3ng.mL (0.1nmol.L) plus the participant's continued requirement for exogenous insulin or oral hypoglycemic agent(s).

C-peptide is a measure of pancreatic function. The definition of pancreatic loss: a C-peptide value of <0.3 ng/mL.

Hemoglobin A1c (HbA1c) measures the average blood glucose levels over 8-12 weeks, thus acting as a useful long-term gauge of blood glucose control:

• A value below 6.0% reflects normal levels,
• 6.0% to 6.4% reflects prediabetes, and
• a value of ≥ 6.5% reflects diabetes.

Fasting blood sugar (e.g., glucose) test is used to help diagnose diabetes, prediabetes, and gestational diabetes.

Reference fasting blood sugar (glucose) values:

• 70 to 99 mg/dL is normal
• 100 to 125 mg/dL is considered prediabetes
• 126 mg/dL or higher on two separate tests is considered diabetes.

A blood pressure measurement consists of two numbers: the systolic and diastolic pressures. Systolic pressure measures the pressure in blood vessels when the heart beats. Diastolic pressure measures the pressure in blood vessels between beats of the heart.

• Systolic measures of <120 and diastolic measures of <80 are considered normal.
• Systolic measures of 120-139 and diastolic measures of 80-89 are considered at risk (or pre-hypertension).
• Systolic measures of ≥140 and diastolic measures of ≥90 are considered high.

Anti-hypertensive medications are a class of drugs that are used to treat hypertension. The medications seek to prevent the complications of high blood pressure, such as stoke and myocardial infarction.

Biopsy-proven acute rejection (AR) of the kidney (renal) or pancreas during the first 52 weeks post-transplant. AR grading using standard Banff* criteria. For both kidney and pancreas, AR is defined as a grade ≥1.

• AR for the kidney: Banff 2007 criteria. Severity of AR is graded by as IA, IB, IIA, IIB, or III, with IA defined as the mildest form of AR and III being the most severe.
• AR for the pancreas: Banff 2011 Criteria. Severity of AR is graded as I, II, or III, with I defined as the mildest form of AR and III being the most severe.

Humoral rejection (i.e., antibody mediated rejection) of:

1. the kidney as defined by diffusely positive staining for C4d, presence of circulating anti-donor antibodies, and morphologic evidence of acute tissue injury determined by local pathology and,
2. the pancreas as defined by the presence of circulating anti-donor antibodies, and histopathological data including morphologic evidence of microvascular tissue injury and C4d staining in interacinar capillaries determined by local pathology.

The de novo development of donor-specific antibody (DSA) is associated with an increased risk of graft rejection.

The presence of anti-Histocompatibility Antigen (HLA) antibodies (alloantibodies) is associated with increased risk of acute and chronic injury to the transplant allograft.

Participants are stratified by kidney biopsy results/treatment received.

In the event of a for cause renal (kidney) biopsy:

-The diagnosis of acute cellular rejection (ACR) using the Banff 2007 renal allograft pathology criteria. These criteria for renal allograft biopsies is an international histopathological classification standard. ACR is defined by a renal biopsy demonstrating a Banff 2007 classification of Grade IA or greater, with higher scores indicating more severe rejection. (Ref: Solez K, Colvin RB et al. Banff 07 classification of renal allograft pathology: updates and future directions. Am J Transplant 2008 8(4): 753-60).

• Kidney Graft Loss was defined as 90 consecutive days of dialysis dependency.
• Pancreas graft loss was defined as returning to exogenous insulin therapy or initiation of oral hypoglycemic agents for greater than 30 days.
• Factitious hypoglycemia due to surreptitious insulin administration results in elevated serum insulin levels and low or undetectable C-peptide levels.

Adverse events were collected systematically. Counts of all participants who experienced at least one adverse event (AEs, SAEs) by assigned treatment group.
