CAMPATH vs LYSODREN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Alemtuzumab is a recombinant humanized monoclonal antibody that binds to CD52, a cell surface antigen expressed on B and T lymphocytes, NK cells, monocytes, and macrophages. Binding induces antibody-dependent cell-mediated cytotoxicity and complement-mediated lysis, resulting in prolonged lymphocyte depletion.
Adrenocorticolytic agent; causes adrenal cortical necrosis and suppresses adrenal steroidogenesis, especially glucocorticoids and mineralocorticoids.
12 mg/day intravenously over 2 hours, administered for 5 consecutive days (total 60 mg). For patients with relapsed/refractory chronic lymphocytic leukemia (CLL), the recommended dose is 3 mg/day intravenously on day 1, 10 mg/day on day 2, and 30 mg/day on day 3 (dose escalation), followed by 30 mg/day three times per week on alternate days for up to 11 weeks (total cumulative dose up to 640 mg).
Oral, initial dose 2-6 g/day divided in 3-4 doses, increase gradually to 8-10 g/day. Maximum dose 18 g/day.

Terminal half-life approximately 12 days (range 6-21 days) after repeated doses, supporting weekly dosing in CLL.
18-159 days; clinical context: during chronic therapy, steady-state may not be reached for 3-6 months.
Clearance via opsonization and degradation in reticuloendothelial system; negligible renal or biliary excretion (<1% unchanged).
Primarily renal excretion of metabolites; about 10% as unchanged drug. Biliary/fecal excretion accounts for <5%.
