DB00087 - Alemtuzumab


Identification
Name Alemtuzumab
Accession Number DB00087 (BIOD00109, BTD00109)
Type biotech
Description Humanized monoclonal antibody specific to lymphocyte antigens. It is a recombinant DNA-derived humanized monoclonal antibody (Campath-1H) that is directed against the 21-28 kD cell surface glycoprotein,CD52. The Campath-1H antibody is an IgG1 kappa with human variable framework and constant regions, and complementarity-determining regions from a murine (rat) monoclonal antibody (Campath-1G). Campath is produced in mammalian cell (Chinese hamster ovary) suspension culture in a medium containing neomycin.

Pharmacology
Indication Alemtuzumab (Campath) is a monoclonal antibody therapy used for treatment of B-cell chronic lymphocytic leukemia.
Mechanism of action Campath binds to the CD52 antigen present on most B and T lymphocytes. This binding leads to antibody-dependent lysis of leukemic cells.
Absorption Not Available
Protein binding Not Available
Biotransformation Most likely removed by opsonization via the reticuloendothelial system when bound to B or T lymphocytes
Route of elimination Not Available
Toxicity Not Available
