Drug Detail:Anti-thymocyte globulin (rabbit) (Anti-thymocyte globulin (rabbit) [ an-tee-thye-moe-syt-glob-ue-lin ])
Drug Class: Selective immunosuppressants
Usual Adult Dose for Renal Transplant
- Prophylaxis of acute rejection: 1.5 mg/kg IV daily for 4 to 7 days with the first dose initiated prior to reperfusion of the donor kidney
- Treatment of acute rejection: 1.5 mg/kg IV daily for 7 to 14 days
Comments:
- Administer this drug with concomitant immunosuppressants.
- Administer the first dose over a minimum of 6 hours; administer doses on subsequent days over at least 4 hours.
- Premedication with corticosteroids, acetaminophen, and/or an antihistamine one hour prior to each infusion is recommended to reduce the incidence and intensity of infusion-related reactions.
- Administer prophylactic antifungal and antibacterial therapy if clinically indicated. Antiviral prophylactic therapy is recommended for patients who are seropositive for cytomegalovirus (CMV) at the time of transplant and for CMV-seronegative patients scheduled to receive a kidney from a CMV-seropositive donor.
- Monitor patients for adverse reactions during and after infusion.
Use: For the prophylaxis and treatment of acute rejection in patients receiving a kidney transplant; this drug is to be used in conjunction with concomitant immunosuppression

Dose Adjustments
- Monitor total white blood cell and platelet counts during and after this drug.
- Reduce the dose of this drug by one-half if the white blood cell (WBC) count is between 2000 and 3000 cells/mm3 or if the platelet count is between 50,000 and 75,000 cells/mm3.
- Consider discontinuing therapy if the WBC count falls below 2000 cells/mm3 or if the platelet count falls below 50,000 cells/mm3.
Precautions
US BOXED WARNINGS:
- This drug should only be used by physicians experienced in immunosuppressive therapy in transplantation.
CONTRAINDICATIONS:
- History of allergy or anaphylactic reaction to rabbit proteins or to any product excipients
- Active acute or chronic infections that contraindicate any additional immunosuppression
Safety and efficacy have not been established in patients younger than 18 years; however, based on limited European studies and US compassionate use, the dose, efficacy, and adverse reaction profile are not thought to be different than for adults.
