Campath® (alemtuzumab) is a recombinant DNA-derived humanized monoclonal antibody (Campath-1H) directed against the 21-28 kD cell surface glycoprotein, CD52. Campath-1H is an IgG1 kappa antibody with human variable framework and constant regions, and complementarity-determining regions from a murine (rat) monoclonal antibody (Campath-1G). The Campath-1H antibody has an approximate molecular weight of 150 kD. Campath is a registered trademark of Genzyme Corporation.
Clolar® (clofarabine) is a purine nucleoside anti-metabolite. It was designed based on previous experience with deoxyadenosine analogues. Clofarabine is sequentially metabolized intracellularly to the 5’-monophosphate metabolite and then to active 5’ – triphosphate metabolite. Clolar is a registered trademark of Genzyme Corporation.
Fludara® (fludarabine phosphate) is a purine nucleoside anti-metabolite. It was developed from earlier antimetabolites for enhanced metabolic stability and solubility. Fludara is a registered trademark licensed to Genzyme Corporation.
Leukine® (sargramostim) is recombinant yeast derived Human granulocyte macrophage colony-stimulating factor (GM-CSF). Leukine is a registered trademark licensed to Genzyme Corporation.
Mozobil® (plerixafor) is a novel small molecule CXCR4 chemokine receptor antagonist. Mozobil is a registered trademark of Genzyme Corporation.
