Uses of Simulect: - Prevention of kidney transplant rejection

Cytotoxic immunosuppressants

Basiliximab functions as an IL-2 receptor antagonist by binding with high affinity to the alpha chain of the high affinity IL-2 receptor complex and inhibiting IL-2 binding. Basiliximab is specifically targeted against IL-2Rα, which is selectively expressed on the surface of activated T-lymphocytes. This specific high affinity binding of Basiliximab to IL-2Rα competitively inhibits IL-2-mediated activation of lymphocytes, a critical pathway in the cellular immune response involved in allograft rejection. While in the circulation, Simulect (basiliximab) impairs the response of the immune system to antigenic challenges. Whether the ability to respond to repeated or ongoing challenges with those antigens returns to normal after Simulect is cleared is unknown

How to use Basiliximab: Your doctor or nurse will give you this medicine. Kindly do not self administer.

May diminish response to inactivated vaccines. May enhance the adverse/ toxic effect of live vaccines, avoid concomitant admin.

Known hypersensitivity to basiliximab or any component of the formulation

Common - Nausea - Constipation - Abdominal pain - Diarrhea - Indigestion - Vomiting - Weight gain - Headache - Pain - Swelling of hands - High blood pressure - Anemia (low number of red blood cells)

Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women. No maternal toxicity, embryotoxicity, or teratogenicity was observed in cynomolgus monkeys 100 days post coitum following dosing with basiliximab during the organogenesis period; blood levels in pregnant monkeys were 13-fold higher than those seen in human patients. Immunotoxicology studies have not been performed in the offspring. Because IgG molecules are known to cross the placental barrier, because the IL-2 receptor may play an important role in development of the immunesystem, and because animal reproduction studies are not always predictive of human response, Basiliximab should only be used in pregnant women when the potential benefit justifies the potential risk to the fetus. Women of childbearing potential should use effective contraception before beginning Basiliximab therapy, during therapy, and for 4 months after completion of Basiliximab therapy.Nursing Mothers: It is not known whether Basiliximab is excreted in human milk. Because many drugs including human antibodies are excreted in human milk, and because of the potential for adverse reactions, a decision should be made to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Re-exposure to a subsequent course of therapy in patient who has previously received basiliximab. Children, Pregnancy and lactation.

A maximum tolerated dose of Basiliximab has not been determined in patients. During the course of clinical studies, Basiliximab has been administered to adult renal transplantation patients in single doses of up to 60 mg, or in divided doses over 3-5 days of up to 120 mg, without any associated serious adverse events. There has been one spontaneous report of a pediatric renal transplantation patient who received a single 20-mg dose (2.3 mg/kg) without adverse events.

Store between 2-8°C. It is recommended that after reconstitution, the solution should be used immediately. If not used immediately, it can be stored at 2º C to 8º C for 24 hours or at room temperature for 4 hours. Discard the reconstituted solution if not used within 24 hours.
