Nulojix
Func. class.:
Biologic response modifier
Chem. class.:
Fusion protein
Activated T lymphocytes are the mediators of immunologic rejection, this product is a selective T-cell costimulation blocker; blocks the CD28 mediated costimulation of T lymphocytes by binding to CD80 and CD86 on antigen-presenting cells; inhibits T lymphocyte proliferation and the production of the cytokines interleukin-2, interferon-gamma, interleukin-4, and TNF-alpha.
Kidney transplant rejection prophylaxis given with basiliximab induction, mycophenolate mofetil, corticosteroids
Hypersensitivity
Precautions:
Breastfeeding, child/infant/neonate, pregnancy (C), diabetes mellitus, progressive multifocal leukoencephalopathy, immunosuppression, sunlight exposure, TB
Black Box Warning:

10 mg/kg rounded to the nearest 12.5 mg increment; give over 30 min the day of transplantation (day 1) but before transplantation, on day 5 approximately 96 hours after the day 1 dose 1, at the end of wk 2, at the end of wk 4, at the end of wk 8, and at the end of wk 12; maintenance dosage is 5 mg/kg rounded to the nearest 12.5 mg increment; give over 30 min at the end of wk 16 and every 4 wk ± 3 days thereafter; doses should be calculated on actual body weight on the transplantation day unless the patient’s weight varies by >10%
Available forms:
Powder for inj 250 mg
Black Box Warning:
Only providers skilled in the use of immunosuppressant and management of transplant should use these products
•
Visually inspect product for particulate matter, discoloration whenever sol/container permit, discard if present
•
Calculate the number of drug vials required to provide total inf dose
•
Reconstitute each vial/10.5 ml of sterile water for injection, 0.9% sodium chloride, D
5
W, using the silicone-free disposable syringe provided with each vial and an 18-21G needle. If silicone-free disposable syringe is dropped or becomes contaminated, use a new silicone-free disposable syringe from inventory. If you need additional silicone-free disposable syringes, call 1-888-685-6549. If the powder is accidentally reconstituted using a different syringe than the one provided, the sol may develop a few translucent particles. Discard any sol prepared using siliconized syringes.
•
Using aseptic technique, inject the diluent into the vial and direct the stream of diluent to the glass wall of the vial; to minimize foaming, rotate the vial and invert with gentle swirling until the contents are dissolved; do not shake when reconstituted (25 mg/ml), should be clear to slightly opalescent and colorless to pale yellow; do not use if opaque particles, discoloration, or other foreign particles are present.
•
Calculate the total volume of the reconstituted 25 mg/ml sol required to provide the total inf dose; further dilute this volume with a volume of inf fluid equal to
the volume of the reconstituted drug sol required to provide the prescribed dose. Use either NS or D

W if drug was reconstituted with SWFI; use NS if drug was reconstituted with NS; use D

W. With the same silicone-free disposable syringe used for reconstitution, withdraw the required amount of belatacept sol from the vial, inject it into the inf container, gently rotate the inf container to ensure mixing; final conc in inf container should range (2-10 mg/ml). Volume of 100 ml will be appropriate for most patients and doses, but total inf volumes ranging from 50-250 ml may be used. Discard any unused drug sol remaining in the vials; after reconstitution, immediately transfer the reconstituted sol from the vial to the inf bag or bottle; complete within 24 hr.
•
Give over 30 min, use an inf set and a sterile, nonpyrogenic, low-protein-binding filter (0.2-1.2 mm), use a separate line

Half-life, 6.1-15.1 days during receipt of 10 mg/kg IV doses; during receipt of 5 mg/kg IV doses, terminal half-life 3.1-11.9; steady-state by wk 8 after transplantation and by month 6 during maintenance phase
Increase:
Basiliximab induction, mycophenolate mofetil
Black Box Warning:
Transplant rejection: flulike symptoms, decreasing urinary output, malaise; some may experience pain in area (rare; monitor BUN/creatinine)
Black Box Warning:
Infection: monitor for fever, chills, increased WBC,
wound dehiscences
Black Box Warning:
Posttransplant lymphoproliferation disorder: may lead to secondary malignancy (lymphoma) or infectious mononucleosis-like lesions; may be treated with antivirals or immunosuppressant; product may need to be discontinued
•
Hyperlipidemia: monitor cholesterol, triglycerides; an antilipidemic may be needed
•
Storage: refrigerated, protected from light ≤24 hr; max 4 hr of the total 24 hr can be at room temp and room light
•
Therapeutic response: absence of renal transplant rejection
•
Reason for product and expected result
•
To avoid exposure to sunlight, tanning beds, risk of secondary malignancy
•
To avoid crowds, persons with known infections
•
That repeated lab test will be needed
•
To avoid with vaccines
•
That immunosuppressants will be needed for life to prevent rejection; teach symptoms of rejection and to call provider immediately

Benlysta
Func. class.:
Monoclonal antibody
Chem. class.:
Disease-Modifying Antirheumatic Drugs (DMARDs)
Inhibits B lymphocyte stimulator (BLyS), needed for B-cell survival; normally, soluble BLyS binds to its receptors on B cells and allows B-cell survival; binds BLyS and prevents binding to its receptors on B-cells
Active, autoantibody-positive, systemic lupus erythematosus (SLE) in combination with standard therapy
