Bevacizumab is a recombinant humanized monoclonal IgG1 antibody that binds to and inhibits vascular endothelial growth factor A (VEGF-A). It is mainly used as an anti-angiogenic agent in the treatment of various cancers and is also approved for ophthalmic use such as neovascular age-related macular degeneration. It is widely approved and used today.
Pharmacokinetics
Population pharmacokinetic parameters reported for typical adult patients receiving intravenous bevacizumab; primarily in oncology treatment and ophthalmology (off-label/compounded for intraocular use).
