What is Nulojix?

Nulojix is a prescription medicine used in adults to prevent transplant rejection in people who have received a kidney transplant. Transplant rejection happens when the body’s immune system senses that the new transplanted kidney is different or foreign, and attacks it. Nulojix is used with corticosteroids and certain other medicines to help prevent rejection of your new kidney.

It is not known if Nulojix is safe and effective in children under 18 years of age.

Nulojix is only used in people who have been exposed to the EBV virus.

It is not known if Nulojix is safe and effective in people who receive an organ transplant other than a kidney transplant.


NULOJIX® (belatacept), a selective T cell costimulation blocker, is a soluble fusion protein consisting of the modified extracellular domain of CTLA-4 fused to a portion (hinge-CH2-CH3 domains) of the Fc domain of a human immunoglobulin G1 antibody. Belatacept is produced by recombinant DNA technology in a mammalian cell expression system. Two amino acid substitutions (L104 to E; A29 to Y) were made in the ligand binding region of CTLA-4. As a result of these modifications, belatacept binds CD80 and CD86 more avidly than abatacept, the parent CTLA4-Immunoglobulin (CTLA4-Ig) molecule from which it is derived. The molecular weight of belatacept is approximately 90 kilodaltons.

NULOJIX is supplied as a sterile, white or off-white lyophilized powder for intravenous administration. Prior to use, the lyophile is reconstituted with a suitable fluid to obtain a clear to slightly opalescent, colorless to pale yellow solution, with a pH in the range of 7.2 to 7.8. Suitable fluids for constitution of the lyophile include SWFI, 0.9% NS, or D5W [see DOSAGE AND ADMINISTRATION (2.2)]. Each 250 mg single-use vial of NULOJIX also contains: monobasic sodium phosphate (34.5 mg), sodium chloride (5.8 mg), and sucrose (500 mg).

Mechanism of Action

Belatacept, a selective T cell (lymphocyte) costimulation blocker, binds to CD80 and CD86 on antigen-presenting cells thereby blocking CD28 mediated costimulation of T lymphocytes. In vitro, belatacept inhibits T lymphocyte proliferation and the production of the cytokines interleukin-2, interferon-γ, interleukin-4, and TNF-α. Activated T lymphocytes are the predominant mediators of immunologic rejection.

In non-human primate models of renal transplantation, belatacept monotherapy prolonged graft survival and decreased the production of anti-donor antibodies, compared to vehicle.

What is the most important information I should know about Nulojix?

Nulojix increases your risk of severe side effects, including:

  • Post-transplant lymphoproliferative disorder (PTLD). PTLD is a condition that can happen if certain white blood cells grow out of control after an organ transplant because your immune system is weak. PTLD can get worse and become a type of cancer. PTLD can lead to death.
    People treated with Nulojix have a higher risk of getting PTLD. If you get PTLD with Nulojix you are at especially high risk of getting it in your brain. Your risk for PTLD is also higher if you:

    • have never been exposed to the Epstein-Barr virus (EBV). Your doctor should test you for EBV. Do not receive Nulojix unless you are EBV positive (exposed to EBV).
    • Get an infection with a virus called cytomegalovirus (CMV).
    • Receive treatment for transplant rejection that lowers certain white blood cells called T lymphocytes.
  • Increased risk of getting cancers other than PTLD. People who take medicines that weaken the immune system, including Nulojix, have a higher risk of getting other cancers, including skin cancer. Talk to your doctor about your risk for cancer. See “What should I avoid while using Nulojix?”
  • Progressive multifocal leukoencephalopathy (PML). PML is a rare, serious brain infection caused by JC virus. People with weakened immune systems are at risk for getting PML. PML can result in death or severe disability. There is no known prevention, treatment, or cure for PML.
  • Increased risk of getting other serious infections, including tuberculosis (TB) and other infections caused by bacteria, viruses, or fungi. These serious infections may lead to death. Also, a virus called BK virus can affect how your kidney works and cause your transplanted kidney to fail.

Tell your doctor right away if you get any of the following symptoms during treatment with Nulojix:

  • change in mood or your usual behavior
  • confusion or problems thinking or with memory
  • change in the way you walk or talk
  • decreased strength or weakness on one side of your body
  • change in vision
  • fever, night sweats, or tiredness that does not go away
  • weight loss
  • swollen glands
  • flu, cold symptoms, or cough
  • stomach-area pain
  • vomiting or diarrhea
  • tenderness over your transplanted kidney
  • change in the amount of urine that you make, blood in your urine, pain or burning on urination
  • a new skin lesion or bump, or change in size or color of a mole

See “What are the possible side effects of Nulojix?” for more information about side effects.

Liver transplant patients should not receive Nulojix because of an increased risk of losing the transplanted liver (graft loss) and death. Talk to your doctor if you would like more information about this risk.

Who should not use Nulojix?

Do not receive treatment with Nulojix if you are EBV negative. Your doctor will do a test to see if you were exposed to EBV in the past.

What should I tell my healthcare provider before using Nulojix?

Before receiving Nulojix, tell your doctor if you:

  • plan to receive any vaccines. Talk to your doctor about which vaccines are safe for you to receive during your treatment with Nulojix. See “What should I avoid while using Nulojix?”
  • have any other medical conditions
  • are pregnant or plan to become pregnant. It is not known if Nulojix will harm your unborn baby. If you become pregnant while taking Nulojix:
    • Tell your doctor right away. You and your doctor should decide if you will keep receiving Nulojix while you are pregnant.
    • Talk with your doctor about enrolling in the National Transplant Pregnancy Registry (NTPR). This Registry collects information about pregnancies in women who have received Nulojix or if their partner has received Nulojix, and had a transplant. You can also enroll by calling 1-877-955-6877.
  • are breast-feeding or plan to breast-feed. It is not known if Nulojix passes into your breast milk. You and your doctor should decide if you will receive Nulojix or breast-feed. You should not do both.

Tell your doctor about all of the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine. Do not take any new medicine without talking with your transplant doctor first.

How should I use Nulojix?

  • To help prevent rejection of your new kidney, you will receive Nulojix regularly as prescribed by your doctor. It is important for you to keep all your appointments for Nulojix treatment and follow up.
  • You will receive Nulojix as an intravenous (IV) infusion in your arm. Each IV infusion takes about 30 minutes.
  • During treatment with Nulojix, your doctor will test your blood and urine to check how your kidney is working.
  • Take all the medicines prescribed by your doctor to prevent infection or transplant rejection. Take them exactly as your doctor tells you. Talk to your doctor or pharmacist if you have any questions about how to take your medicines.

What should I avoid while using Nulojix?

  • Limit the amount of time you spend in sunlight. Avoid using tanning beds or sunlamps. People who take medicines that weaken the immune system, including Nulojix, have a higher risk of getting cancer, including skin cancer. Wear protective clothing and use sunscreen with a high protection factor (SPF) when you have to be in the sun.
  • Avoid receiving live vaccines during treatment with Nulojix. Talk to your doctor to find out which vaccines are safe for you during this time. Some vaccines may not work as well while you are receiving Nulojix. See “What should I tell my healthcare provider before using Nulojix?”
