The therapy is recommended as an initial treatment of 2 courses with up to 2 additional treatment courses if needed with safety follow-up of patients from initiation of the first treatment course and for at least 48 months after the last infusion of the second treatment course. If an additional third or fourth course is administered, continue safety follow-up for at least 48 months after the last infusion.

Pre-treatment

Patients should be pre-treated with corticosteroids immediately prior to alemtuzumab administration on each of the first 3 days of any treatment course. In clinical trials, patients were pre-treated with 1,000 mg methylprednisolone for the first 3 days of each alemtuzumab treatment course.

Pretreatment with antihistamines and/or antipyretics prior to alemtuzumab administration may also be considered.

Oral prophylaxis for herpes infection should be administered to all patients starting on the first day of each treatment course and continuing for a minimum of 1 month following treatment with alemtuzumab. In clinical trials, patients were administered aciclovir 200 mg twice a day or equivalent.

Dosage considerations

Alemtuzumab must be diluted before infusion. The diluted solution should be administered by intravenous infusion over a period of approximately 4 hours.

Active ingredient

Alemtuzumab

Alemtuzumab is a genetically engineered humanised IgG1 kappa monoclonal antibody specific for a 21-28 kD lymphocyte cell surface glycoprotein (CD52) expressed primarily on the surface of normal and malignant peripheral blood B and T cell lymphocytes. Alemtuzumab acts through antibody-dependent cellular cytolysis and complement-mediated lysis following cell surface binding to CD52, a cell surface antigen present at high levels on T (CD3+) and B (CD19+) lymphocytes, and at lower levels on natural killer cells, monocytes, and macrophages.
