Belatacept, sold under the brand name Nulojix, is a medication used to prevent rejection following a kidney transplant.[2] It is used with corticosteroids and mycophenolic acid.[3] Use in the United Kingdom is not generally recommended.[1] It is given by injection into a vein.[3]

Common side effects include low red blood cells, diarrhea, urinary tract infection, swelling, constipation, fever, cough, nausea, and low or high potassium.[2] Other side effects may include infections, cancer, and posttransplant lymphoproliferative disorder.[4] It is a recombinant fusion protein which acts as a T cell activation inhibitor.[1][4]

Belatacept was approved for medical use in the United States and Europe in 2011.[2][3] In the United Kingdom 250 mg costs the NHS about £355 as of 2021.[1] This amount in the United States is about 930 USD.[5]

Medical uses


It is initially given at a dose of 10 mg/kg at the time of surgery.[3] Further doses are than given at days 5, 14, and 28 and at 8 and 12 weeks.[3] Further doses of 5 mg/kg are than given every 4 weeks.[3]


It is a fusion protein composed of the Fc fragment of a human IgG1 immunoglobulin linked to the extracellular domain of CTLA-4, which is a molecule crucial in the regulation of T cell costimulation, selectively blocking the process of T-cell activation. It differs from abatacept (Orencia) by only two amino acids.
