Solution Reconstituted, Intravenous:
Nulojix: 250 mg (1 ea)
Brand Names: U.S.
- Selective T-Cell Costimulation Blocker
Fusion protein which acts as a selective T-cell (lymphocyte) costimulation blocker by binding to CD80 and CD86 receptors on antigen presenting cells (APC), blocking the required CD28 mediated interaction between APCs and T cells needed to activate T lymphocytes. T-cell stimulation results in cytokine production and proliferation, mediators in immunologic rejection associated with kidney transplantation.

Off Label Uses
Lung transplant, prophylaxis of organ rejection
Data from a limited number of patients studied (case study of 8 lung transplant recipients) with renal dysfunction post-transplant suggest that belatacept for maintenance immunosuppression may be beneficial to reduce calcineurin inhibitor dose and prevent rejection while preserving renal function after lung transplantation. Additional data may be necessary to further define the role of belatacept in lung transplant recipients. [Timofte 2016].
Transplant patients who are Epstein-Barr virus (EBV) seronegative or with unknown EBV serostatus due to increased risk for post transplant lymphoproliferative disorder (PTLD).
Note: Dosing is based on actual body weight at the time of transplantation; do not modify weight-based dosing during course of therapy unless the change in body weight is >10%. The prescribed dose must be evenly divisible by 12.5 mg to allow accurate preparation of the reconstituted solution using the provided required disposable syringe for preparation. For example, the calculated dose for a 64 kg patient: 64 kg x 10 mg per kg = 640 mg. The nearest doses to 640 mg that are evenly divisible by 12.5 mg would be 637.5 mg or 650 mg; the closest dose to the calculated dose is 637.5 mg, therefore, 637.5 should be the actual prescribed dose for the patient.
Kidney transplant, prophylaxis of organ rejection: IV: Note: Use in combination with basiliximab induction, mycophenolate mofetil, and corticosteroids.
Initial phase: 10 mg/kg on day 1 (day of transplant, prior to implantation) and on day 5 (~96 hours after day 1 dose), followed by 10 mg/kg at the end of week 2, week 4, week 8, and week 12 following transplantation
Maintenance phase: 5 mg/kg every 4 weeks (plus or minus 3 days) beginning at the end of week 16 following transplantation
Conversion from calcineurin inhibitor (off-label dosing) (Grinyo 2012; Grinyo 2016; Rostaing 2011): IV:
Initial phase: 5 mg/kg on transition days 1, 15, 29, 43, and 57
Maintenance phase: 5 mg/kg every 4 weeks beginning 4 weeks after completion of the initial phase. Note: Taper calcineurin inhibitor dose slowly over 1 month (no reduction on day 1, 40% to 60% reduction on day 15, 70% to 80% reduction on day 23; discontinue on day 29 and beyond).
Lung transplant, prophylaxis of organ rejection (off-label use): IV:
Initial phase: 10 mg/kg on days 0 and 4, and again at weeks 2 and 4 (Timofte 2016)
Maintenance phase (for chronic treatment patients only): 10 mg/kg every month beginning 4 weeks after completion of the initial phase (Timofte 2016)
Refer to adult dosing.
Dosing: Renal Impairment
There are no dosage adjustments provided in the manufacturer’s labeling; however, renal function did not affect clearance in pharmacokinetic studies of kidney transplant patients.
Dosing: Hepatic Impairment
There are no dosage adjustments provided in the manufacturer’s labeling; however, hepatic function did not affect clearance in pharmacokinetic studies of kidney transplant patients.
Reconstitute each vial with 10.5 mL of diluent (SWFI, NS, or D5W only) using the provided silicone-free disposable syringe, and an 18- to 21-gauge needle. Reconstitute using only the silicone-free syringe provided; if the provided silicone-free syringe is dropped or becomes contaminated, use a new silicone-free disposable syringe from inventory (contact the manufacturer on obtaining additional silicone-free disposable syringes). If powder is inadvertently mixed using a siliconized syringe, discard solution; translucent particles may develop. Inject the diluent down the side of the vial to avoid foaming. Rotate the vial and invert with gentle swirling until completely dissolved; do not shake vial. Immediately transfer the reconstituted solution using the same silicone-free syringe to an infusion bag or bottle with NS or D5W (if NS or D5W were used to reconstitute, the same fluid should be used to further dilute). Gently rotate the infusion bag or bottle; do not shake. The final concentration should range from 2 mg/mL and 10 mg/mL (typical infusion volume is 100 mL; volumes ranging from 50 mL to 250 mL may be used). Prior to adding belatacept to the infusion solution, the manufacturer recommends withdrawing a volume equal to the amount of belatacept to be added.
Administer as an IV infusion over 30 minutes using an infusion set with a 0.2 to 1.2 micron low protein-binding filter. The infusion must be completed within 24 hours of reconstitution of the lyophilized powder. Infuse in a separate line from other infused agents.
Prior to use, store refrigerated at 2°C to 8°C (36°F to 46°F). Protect from light. After dilution, the reconstituted solution should be transferred from the vial to infusion bag or bottle immediately; infusion solution in NS or D5W may be stored refrigerated for up to 24 hours, with a maximum of 4 hours of the 24 hours at room temperature, 20°C to 25°C (68°F to 77°F), and room light. Infusion must be completed within 24 hours of reconstitution. Discard unused solution in vials.

Concerns related to adverse effects:
• Infections: [US Boxed Warning]: Risk for infection is increased. Immunosuppressive therapy may lead to bacterial, viral (cytomegalovirus [CMV] and herpes), fungal, and protozoal infections, including opportunistic infections (may be fatal). Tuberculosis (TB) is increased; test patients for latent TB prior to initiation, and treat latent TB infection prior to use. Prophylaxis for cytomegalovirus (CMV) is recommended for at least 3 months after transplantation; prophylaxis for Pneumocystis jirovecii is recommended after transplantation.
• Latent viral infections: Patients receiving immunosuppressive therapy are at an increased risk of activation of latent viral infections, including John Cunningham virus (JCV) and BK virus infection. Activation of JCV may result in progressive multifocal leukoencephalopathy (PML), a rare and potentially-fatal condition affecting the CNS. Symptoms of PML include apathy, ataxia, cognitive deficiencies, confusion, and hemiparesis. Polyoma virus-associated nephropathy (PVAN), primarily from activation of BK virus, may also occur and lead to the deterioration of renal function and/or renal graft loss. Risk factors for the development of PML and PVAN include immunosuppression and treatment with immunosuppressant therapy. The onset of PML or PVAN may warrant a reduction in immunosuppressive therapy; however, in transplant recipients, the risk of reduced immunosuppression and graft rejection should be considered.
• Lymphoproliferative disorders: [US Boxed Warning]: Risk of post-transplant lymphoproliferative disorder (PTLD) is increased, primarily involving the CNS, in patients receiving belatacept compared to patients receiving cyclosporine-based regimens. Degree of immunosuppression is a risk factor for PTLD developing; do not exceed recommended dosing. Patients who are Epstein-Barr virus (EBV) seronegative are at an even higher risk; use is contraindicated in patients without evidence of immunity to EBV. Cytomegalovirus (CMV) infection and T-cell depleting therapy also increases the risk for PTLD; T-cell depleting therapies to treat acute rejection should be used with caution. CMV prophylaxis is recommended for a minimum of 3 months following transplantation. Although CMV disease is a risk for PTLD and CMV seronegative patients are at an increased risk for CMV disease, the clinical role, if any, of determining CMV serology to determine risk of PTLD development has not been determined.
• Malignancy: [US Boxed Warning]: Risk for malignancy is increased. Malignancy, including skin malignancy and PTLD, is associated with the use of belatacept; patients should be advised to limit their exposure to sunlight/UV light.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Appropriate use: [US Boxed Warning]: Therapy is not recommended in liver transplant patients due to increased risk of graft loss and death.
• Corticosteroid minimization: Increased rate and grade of acute rejection, particularly grade 3 rejection, and graft loss has been observed with belatacept when corticosteroids were minimized to 5 mg daily between day 3 and week 6 post-transplant; corticosteroid dosing should be consistent with clinical trial experience (ie, tapered to ~15 mg [10 to 20 mg] daily by the first 6 weeks post-transplant and remain at ~10 mg [5 to 10 mg] daily for the first 6 months post-transplant).
• EBV serostatus: Therapy is only appropriate in patients who are EBV seropositive via evidence of acquired immunity, such as presence of IgG antibodies to viral capsid antigen [VCA] and EBV nuclear antigen [EBNA].
• Experienced physician: [US Boxed Warning]: Should be administered under the supervision of a physician experienced in immunosuppressive therapy.
• Immunizations: Immunization with live vaccines should be avoided during treatment.
Monitor for new-onset or worsening neurological, cognitive, or behavioral signs/symptoms; signs/symptoms of infection or malignancy; gastrointestinal side effects (eg, nausea, vomiting, diarrhea); TB screening prior to therapy initiation; EBV serostatus verification prior to therapy initiation (only use belatacept in seropositive patients); potassium, magnesium.
Pregnancy Risk Factor
Adverse events have been observed in animal reproduction studies.
The National Transplantation Pregnancy Registry (NTPR) is a registry which follows pregnancies which occur in maternal transplant recipients or those fathered by male transplant recipients. The NTPR encourages reporting of pregnancies following solid organ transplant by contacting them at 877-955-6877 or NTPR@giftoflifeinstitute.org.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience constipation, diarrhea, nausea, vomiting, abdominal pain, joint pain, anxiety, back pain, or insomnia. Have patient report immediately to prescriber signs of electrolyte problems (mood changes, confusion, muscle pain or weakness, abnormal heartbeat, seizures, lack of appetite, or severe nausea or vomiting), signs of infection, signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), severe headache, severe dizziness, passing out, vision changes, mood changes, behavioral changes, severe loss of strength and energy, shortness of breath, swelling of arms or legs, excessive weight loss, night sweats, swollen glands, mole changes, skin growths, signs of progressive multifocal leukoencephalopathy (confusion, depression, memory impairment, mood changes, behavioral changes, change in strength on one side is greater than the other, difficulty speaking, change in balance, or vision changes), or signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
