Current Primary Outcome Measures ^ICMJE

Mean Estimated Glomerular Filtration Rate (eGFR) Calculated for Each Treatment Group Using the CKD-EPI Equation at Wk 52 Post-Transplant [ Time Frame: Week 52 ]

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.

Mean Calculated eGFR Using MDRD 4 Variable Model at Wk 52 Post-Transplant [ Time Frame: Week 52 ]
The estimated Glomerular Filtration Rate (eGFR) was calculated using the Modification of Diet in Renal Disease equation (MDRD):

- 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 [ Time Frame: Day 28 through Week 52 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.

Acute cellular rejection for this endpoint is defined as a grade equal to or greater than IA by Banff 2007 criteria as determined by local pathology.
Count of Participants by Severity of First Acute Cellular Rejection by Wk 52 Post-Transplant [ Time Frame: Transplantation through Week 52 ]
Acute cellular rejection occurs when lesions at the site of the graft characteristically are infiltrated with large numbers of lymphocytes and macrophages that cause tissue damage. Acute cellular rejection for this endpoint is defined as a grade equal to or greater than IA by Banff 2007 criteria as determined by local pathology. Severity is graded as IA, IB, IIA, IIB, or III, with IA being the mildest form of cellular rejection and III being the most severe form of cellular rejection. Originally it was 2 endpoints but all participants' highest grade was also their first grade so only reporting their first grade.

Brief Title ^ICMJE

Open-Label Phase 2 Trial of a Steroid-Free, CNI-Free, Belatacept-Based Immunosuppressive Regimen

Official Title ^ICMJE

Steroid and Tacrolimus Avoidance Using NULOJIX® (Belatacept) in Renal Transplantation (CTOT-16)

Brief Summary

The primary objective is to evaluate a NULOJIX® (belatacept) based regimens as a means of improving long-term graft function without increasing the risks of immunologic graft injury by avoiding both calcineurin inhibitors (CNIs) and corticosteroids.

Detailed Description

Taking standard anti-rejection medications for a long time can cause serious side effects, including kidney damage. Transplant recipients have to take anti-rejection medications to prevent their immune system (the body's natural defense system against illness) from rejecting their new kidney. Most patients who receive a kidney transplant must take these anti-rejection medications for the rest of their lives, or for as long as the kidney continues to work.

The purpose of this study is to determine if NULOJIX® (belatacept), will minimize serious long term side effects seen with anti-rejection medications while still protecting the transplanted kidney from damage. The researchers also want to learn more about the safety of this treatment and the long term health of the transplanted kidney.
