Introduction

Immunosuppressive agent; recombinant DNA-derived chimeric (human-murine) monoclonal antibody.^{1 2 3 4 5}

Uses for Basiliximab

Renal Allotransplantation

Basiliximab Dosage and Administration

Administration

IV Administration

Administer only by direct IV (“bolus”) injection or IV infusion via a central or peripheral line.^{1 7}

Direct IV injection may be associated with nausea, vomiting, and local reactions, including pain.^{1 7}

Administer in conjunction with cyclosporine and corticosteroid therapy.¹

Administer only when it has been determined that the patient will receive the graft and concomitant immunosuppressive therapy.¹

Reconstitution

20 mg vial: add 5 mL of sterile water for injection.¹ Reconstituted solution is isotonic; may administer by direct IV injection or dilute for IV infusion.¹

Shake vial gently to dissolve.¹

Dilution

10 mg vial: for IV infusion, dilute reconstituted solution to 25 mL with 0.9% sodium chloride or 5% dextrose injection.^a

Gently invert the IV bag to mix the solution without foaming; do not shake.¹

Rate of Administration

For IV infusion, administer over 20–30 minutes.¹

Dosage

Pediatric Patients

Renal Allotransplantation

Prevention of Allograft Rejection in Children 1–16 Years of Age

Adults

Renal Allotransplantation

Prevention of Allograft Rejection

IV

2 doses, 20 mg each, by direct IV injection or IV infusion.

Withhold second dose if complications (e.g., severe hypersensitivity reactions, graft loss) occur after the first dose.¹

Prescribing Limits

Pediatric Patients

Renal Allograft

IV

Not determined; at least one pediatric renal transplant patient received single 20-mg dose (2.3 mg/kg) without adverse events.¹

Adults

Renal Allograft

IV

Not determined; single doses up to 60 mg or divided doses over 3-5 days of up to 120 mg given without serious adverse effects.¹

Special Populations

Geriatric Patients

Dosage adjustment is not required for geriatric patients; in general, use immunosupressive agents with caution.¹

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 Infections

Monitor 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 Response

Not known whether the immune response to vaccines, infection, and other antigens is impaired during therapy or will remain impaired following therapy.¹

Immunogenicity

An 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

Pregnancy

Category B.¹

Manufacturer recommends use of effective contraception before, during, and for 4 months following basiliximab use in women of childbearing potential.¹

Lactation

Not known whether basiliximab is distributed into milk.¹ Discontinue nursing or the drug.¹

Pediatric Use

Use 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 Use

Limited 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}

Common Adverse Effects

Constipation, nausea, diarrhea, abdominal pain, vomiting, dyspepsia, hyperkalemia, hypokalemia, hyperglycemia, hyperuricemia, hypophosphatemia, hypercholesterolemia, headache, tremor, urinary tract infection, pain, peripheral edema, fever, viral infection, hypertension, dyspnea, upper respiratory tract infection, surgical wound complications, acne, insomnia, anemia.^{1 2 3}
