Belatacept Therapy for the Failing Renal Allograft

Completed · Phase 3

Conditions studied: Failing Renal Allograft

In brief

The purpose of this study is to test the safety and effectiveness of belatacept (Nulojix®) in preventing antibody formation in patients with chronic failing kidney transplants. This study is a randomized study of first-time kidney transplant patients who have worsening kidney function and biopsy proven grade 2 or 3 interstitial fibrosis/tubular atrophy (IF/TA). Patients must be eligible to get a second transplant. They must have completed or be actively undergoing evaluation for re-listing for a second transplant. Patients will be randomized to either convert to belatacept or continue on calcineurin inhibitor-based therapy.

Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Signed written informed consent
Kidney transplant recipient (human leukocyte antigen (HLA) non-identical donor) who now has impaired renal allograft function with:
Estimated glomerular filtration rate (GFR) < 35 with a decline in GFR of > 10% in the 12 months prior to enrollment and must have biopsy proven grade II or III interstitial fibrosis/tubular atrophy (IF/TA) OR
Estimated GFR persistently < 20 ml/min over the 6 month period prior to enrollment absent other causes for graft dysfunction, and deemed to have a failing allograft by the patient's transplant nephrologist
On a maintenance immunosuppressive regimen that includes calcineurin inhibitor (CNI)(tacrolimus or cyclosporine) or sirolimus and at least
MMF of a dose of at least 1 gm/day or comparable dose of azathioprine OR
Prednisone at a dose of at least 5 mg/day
Men and women, ages 18 to 70, inclusive

You may not qualify if…

Women of childbearing potential (WOCBP) who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for up to 8 weeks after the last dose of study drug.
Women who are pregnant or breastfeeding.
Women with a positive pregnancy test.
Sexually active fertile men not using effective birth control if their partners are WOCBP.
Subjects who are Epstein-Barr Virus (EBV) seronegative.
Subjects with any prior solid organ (e.g., heart, liver, pancreas) or cell (e.g., islet, bone marrow) transplant other than a renal allograft. Exception may be made for recipient of a simultaneous kidney-pancreas transplant who had previously experienced graft loss of the pancreas allograft due to thrombosis or rejection.
Subjects with presence of donor specific antibody at the time of enrollment
Subjects who have a recent history (within 1 yr) of biopsy proven acute rejection > Banff grade Ia
Subjects who have a living donor identified for re-transplant within 3 months
Subjects with a history of post-transplant lymphoproliferative disease (PTLD)
Subjects at risk for tuberculosis (TB)
Subjects with a history of cancer within the past 3 years, other than non-melanoma skin cancer(s)
Subjects with a positive BK virus serum polymerase chain reaction (PCR) > 20,000 copies at the time of enrollment OR history of biopsy-proven BK nephropathy within the year prior to enrollment.
Subjects with a mammogram that is suspicious for malignancy and in whom the possibility of malignancy cannot be reasonably excluded following additional clinical, laboratory, or other diagnostic evaluations
Subjects who have difficult intravenous access or other reasons that would likely preclude the ability to receive long-term intravenous infusions
Hypersensitivity to any medications that will be used in the protocol
Subjects who have used any investigational drug within the 30 days prior to anticipated enrollment
Subjects currently receiving belatacept as part of their maintenance immunosuppressive regimen
Prisoners, or subjects who are involuntarily incarcerated.
Subjects who are compulsorily detained for treatment of either a psychiatric or physical (eg, infectious disease) illness.
