The purpose of this study is to find out if the drug NULOJIX® (belatacept) will minimize the amount of other anti-rejection medications necessary and thereby reduce the long-term side effects caused by the other medications. The researchers also want to learn more about the safety of this treatment and long term health of transplanted pancreases and kidneys.
Transplant recipients have to take anti-rejection medications to prevent their immune systems (the body's natural defense system against illness) from rejecting their new organs. Most patients who receive a transplanted organ must take these anti-rejection medications for the rest of their lives, or for as long as the transplanted organ continues to work. Taking standard anti-rejection medications for a long time can cause serious side effects, including pancreas and kidney damage. There would be a benefit to finding new anti-rejection medications that work just as well, but could lessen the amount of anti-rejection medications that are taken long term.

Mean Calculated eGFR Using MDRD 4 Variable Model at Wk 52 Post-Transplant
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.

The Slope of eGFR by CKD-EPI Over Time Based on Serum Creatinine Post-Transplant
The estimated Glomerular Filtration Rate (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 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.
