Description
Simulect® (basiliximab) is a chimeric (murine/human) monoclonal antibody (IgG1K), produced by recombinant DNA technology, that functions as an immunosuppressive agent, specifically binding to and blocking the interleukin-2 receptor α-chain (IL-2Rα, also known as CD25 antigen) on the surface of activated T-lymphocytes. Based on the amino acid sequence, the calculated molecular weight of the protein is 144 kilodaltons. It is a glycoprotein obtained from fermentation of an established mouse myeloma cell line genetically engineered to express plasmids containing the human heavy and light chain constant region genes and mouse heavy and light chain variable region genes encoding the RFT5 antibody that binds selectively to the IL-2Rα.
The active ingredient, basiliximab, is water soluble. The drug product, Simulect (basiliximab) , is a sterile lyophilisate which is available in 6 mL colorless glass vials and is available in 10 mg and 20 mg strengths.
Each 10-mg vial contains 10 mg basiliximab, 3.61 mg monobasic potassium phosphate, 0.50 mg disodium hydrogen phosphate (anhydrous), 0.80 mg sodium chloride, 10 mg sucrose, 40 mg mannitol and 20 mg glycine, to be reconstituted in 2.5 mL of Sterile Water for Injection, USP. No preservatives are added.
Each 20-mg vial contains 20 mg basiliximab, 7.21 mg monobasic potassium phosphate, 0.99 mg disodium hydrogen phosphate (anhydrous), 1.61 mg sodium chloride, 20 mg sucrose, 80 mg mannitol and 40 mg glycine, to be reconstituted in 5 mL of Sterile Water for Injection, USP. No preservatives are added.
Warnings
See Boxed WARNING.
General
Simulect® (basiliximab) should be administered under qualified medical supervision. Patients should be informed of the potential benefits of therapy and the risks associated with administration of immunosuppressive therapy.
While neither the incidence of lymphoproliferative disorders nor opportunistic infections was higher in Simulect (basiliximab) -treated patients than in placebo-treated patients, patients on immunosuppressive therapy are at increased risk for developing these complications and should be monitored accordingly.
Hypersensitivity
Severe acute (onset within 24 hours) hypersensitivity reactions including anaphylaxis have been observed both on initial exposure to Simulect (basiliximab) and/or following re-exposure after several months. These reactions may include hypotension, tachycardia, cardiac failure, dyspnea, wheezing, bronchospasm, pulmonary edema, respiratory failure, urticaria, rash, pruritus, and/or sneezing. Extreme caution should be exercised in all patients previously given Simulect (basiliximab) when being administered a subsequent course of Simulect (basiliximab) . A subgroup of patients may be particularly at risk of developing severe hypersensitivity reactions on re-administration. These are patients in whom concomitant immunosuppression was discontinued prematurely (e.g., due to abandoned transplantation or early loss of the graft) following the initial administration of Simulect (basiliximab) . If a severe hypersensitivity reaction occurs, therapy with Simulect (basiliximab) should be permanently discontinued. Medications for the treatment of severe hypersensitivity reactions including anaphylaxis should be available for immediate use.

Patient Handout
Basiliximab Drug Class
Basiliximab is part of the drug class:
Interleukin inhibitors
Basiliximab Dosage
Take this medication exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.
The dose your doctor recommends may be based on the following:
- the condition being treated
- other medical conditions you have
- how you respond to this medication
In adult patients, the recommended Simulect (basiliximab) regimen is two doses of 20 mg each. The first dose should be given within 2 hours prior to transplantation surgery. The recommended second dose should be given 4 days after transplantation.
How is basiliximab given?
Basiliximab is injected into a vein through an IV. You will receive this injection just before your transplant and again 4 days afterward. Basiliximab must be given slowly, and the IV infusion can take up to 30 minutes to complete.
Basiliximab can lower blood cells that help your body fight infections and help your blood clot. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Your blood may need to be tested often. Visit your doctor regularly.
What happens if I overdose?
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
Cautions for Basiliximab
Contraindications
-
Known hypersensitivity to basiliximab or any ingredient in the formulation.1
Warnings/Precautions
Warnings
(See Boxed Warning.)
Lymphoproliferative Disorders and Opportunistic InfectionsMonitor patients for lymphoproliferative disorders and/or opportunistic infections; risk is increased with immunosuppressive therapy.1
Neither complication occurred more often with basiliximab than with placebo in clinical trials.1
Sensitivity Reactions
Severe, acute (onset within 24 hours) hypersensitivity reactions, including anaphylaxis, have occurred after initial basiliximab exposure and subsequent reexposure.1
Drugs to treat severe hypersensitivity reactions, including anaphylaxis, should be immediately available.1
In patients who have previously received the drug, a subsequent course of therapy with basiliximab should be given with extreme caution; risks of subsequent administration not known.1
If hypersensitivity reaction occurs, immediately and permanently discontinue basiliximab and institute appropriate therapy as indicated (e.g., epinephrine, corticosteroids, maintenance of an adequate airway and oxygen).1
Patients who have a severe hypersensitivity reaction to basiliximab should not receive the drug again.1
Immune ResponseNot known whether the immune response to vaccines, infection, and other antigens is impaired during therapy or will remain impaired following therapy.1
ImmunogenicityAn anti-idiotype antibody response has been detected in renal-transplant patients treated with basiliximab.1 5 No deleterious clinical effect and no evidence of faster basiliximab clearance or shorter duration of basiliximab saturation of IL-2Rα detected in the presence of anti-idiotype antibody.1 Clinical data suggest that subsequent use of muromonab-CD3 or other murine anti-lymphocytic antibody preparations is not precluded.1
Specific Populations
PregnancyCategory B.1
Manufacturer recommends use of effective contraception before, during, and for 4 months following basiliximab use in women of childbearing potential.1
LactationNot known whether basiliximab is distributed into milk.1 Discontinue nursing or the drug.1
Pediatric UseUse in children 1–16 years of age for prevention of renal allograft rejection is supported by limited data from a pediatric safety and pharmacokinetic study.1 7
Geriatric UseLimited data in patients ≥65 years of age suggest an adverse effect profile similar to that in younger adults; use immunosuppressive drugs with caution in such patients.1 7

Pharmacology
Chimeric (murine/human) immunosuppressant monoclonal antibody which blocks the alpha-chain of the interleukin-2 (IL-2) receptor complex; this receptor is expressed on activated T lymphocytes and is a critical pathway for activating cell-mediated allograft rejection
Distribution
Mean: Vd: Children 1 to 11 years: 4.8 ± 2.1 L; Adolescents 12 to 16 years: 7.8 ± 5.1 L; Adults: 8.6 ± 4.1 L
Excretion
Clearance:
Children 1 to 11 years: 17 ± 6 mL/hour; in pediatric liver transplant patients, significant basiliximab loss through ascites fluid can increase total body clearance and reduce IL-2R (CD25) saturation duration; dosage adjustments may be necessary (Cintorino 2006; Kovarik 2002; Spada 2006)
Adolescents 12 to 16 years: 31 ±19 mL/hour
Adults: 41 ± 19 mL/hour
Off Label Uses
Acute graft-versus-host disease, refractory (treatment)
Data from a small nonrandomized phase II study in patients with steroid refractory acute graft-versus-host-disease (aGVHD) following allogeneic stem cell transplant suggest that basiliximab may be beneficial in the treatment of refractory aGVHD [Schmidt-Hieber 2005]. Additional data may be necessary to further define the role of basiliximab in this condition.
Heart transplant (prophylaxis of acute rejection)
Data from a randomized, placebo-controlled, double blind, multicenter study in de novo heart transplant recipients supports the use of basiliximab (in combination with other immunosuppressants [ie, cyclosporine, mycophenolate, and prednisone]) in the prevention cardiac transplant rejection [Mehra 2005]. Additional trials may be necessary to further define the role of basiliximab in this condition.
Liver transplant (prophylaxis of acute rejection)
Data from a multicenter, randomized, open-label phase IIIb trial in liver transplant patients supports the use of basiliximab (in combination with tacrolimus) for the prevention of acute rejection [Trunecka 2015]. Additional data from a multicenter, randomized, placebo-controlled, double blind study in liver transplant recipients supports the use of basiliximab (in combination with other immunosuppressants [ie, cyclosporine and corticosteroids]) in the prevention of liver transplant rejection [Neuhaus 2002]. A meta analysis evaluating rejection prevention in liver transplant recipients suggests that interleukin 2 receptor antagonist therapy (eg, basiliximab) may be beneficial in reducing episodes of acute rejection, but does not appear to improve overall survival in these patients [Zhang 2016]. Additional trials may be necessary to further define the role of basiliximab in this condition.
Lung transplant (prophylaxis of acute rejection)
A retrospective analysis of data obtained from the United Network for Organ Sharing (UNOS) registry supports the use of basiliximab as induction therapy in patients receiving double lung transplants [Furuya 2016]. Data from other retrospective reviews suggest that basiliximab may be beneficial in prevention of lung transplant rejection [Clinckart 2009], [Swarup 2011]. Additional data may be necessary to further define the role of basiliximab in prevention of lung transplant rejection.
Contraindications
Known hypersensitivity to basiliximab or any component of the formulation
Dosing Adult
Note: Patients previously administered basiliximab should only be re-exposed to a subsequent course of therapy with extreme caution.
Renal transplant (prophylaxis of acute rejection): IV: 20 mg within 2 hours prior to transplant surgery, followed by a second 20 mg dose 4 days after transplantation (in combination with other immunosuppressants). The second dose should be withheld if complications occur (including severe hypersensitivity reactions or graft loss). Timing of basiliximab dosing may vary based on clinical and institutional factors; refer to institutional protocol for specific information.
Acute graft-versus-host disease (aGVHD), refractory (treatment) (off-label use): IV: 20 mg on days 1 and 4; may repeat for recurrent acute GVHD (Schmidt-Hieber 2005). Additional data may be necessary to further define the role of basiliximab in this condition.
Heart transplant (prophylaxis of acute rejection) (off-label use): IV: 20 mg on the day of transplant, followed by a second 20 mg dose on day 4 post-transplantation (in combination with other immunosuppressants) (Mehra 2005). The first dose is usually administered immediately prior to transplant or within the first hours postoperatively.
Liver transplant (prophylaxis of acute rejection) (off-label use): IV: 20 mg on the day of transplant (day 0), followed by a second 20 mg dose on day 4 post-transplantation (in combination with other immunosuppressants) (Neuhaus 2002; Trunecka 2015). In clinical trials, the first dose was administered during the procedure once hemostasis was achieved or immediately post-transplant, or within 6 hours of organ reperfusion.
Lung transplant (prophylaxis of acute rejection) (off-label use): IV: 20 mg prior to transplantation, followed by a second 20 mg dose 4 days after transplantation (in combination with other immunosuppressants) (Clinckart 2009; Swarup 2011). Additional trials may be necessary to further define the role of basiliximab in this condition.
Reconstitution
Reconstitute with preservative-free sterile water for injection (reconstitute 10 mg vial with 2.5 mL, 20 mg vial with 5 mL). Shake gently to dissolve. May further dilute reconstituted solution with 25 mL (10 mg) or 50 mL (20 mg) 0.9% sodium chloride or dextrose 5% in water. When mixing the solution, gently invert the bag to avoid foaming. Do not shake solutions diluted for infusion.
