Basic Information

Mechanism Of Action

Trastuzumab binds to an extracellular domain of this receptor and inhibits HER2 homodimerization, thereby preventing HER2-mediated signaling. It is also thought to facilitate antibody-dependent cellular cytotoxicity, leading to the death of cells that express HER2.

Pharmacokinets

Trastuzumab pharmacokinetics are characterized by a low systemic clearance, a low volume of distribution (4l) and a very long half-life (28 days) comparable to that of endogenous immunoglobulins G. The elimination pathways are not yet defined and the clinical relevance of trastuzumab kinetic variability is unknown
