Overview
11 DESCRIPTION Brolucizumab-dbll is a recombinant human vascular endothelial growth factor inhibitor. Brolucizumab-dbll is a humanized monoclonal single-chain Fv (scFv) antibody fragment. Brolucizumab-dbll has a molecular weight of ~26 kilodaltons and is produced in Escherichia coli cells by recombinant DNA technology.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Brolucizumab is a human VEGF inhibitor. Brolucizumab binds to the three major isoforms of VEGF-A (e.g., VEGF 110 , VEGF 121 , and VEGF 165 ), thereby preventing interaction with receptors VEGFR-1 and VEGFR-2. By inhibiting VEGF-A, brolucizumab suppresses endothelial cell proliferation, neovascularization, and vascular permeability. 12.2 Pharmacodynamics Leakage of blood and fluid from choroidal neovascularization (CNV) may cause retinal thickening or edema. Increased retinal thickness and accumulation of intraretinal fluid (IRF)/subretinal fluid (SRF), assessed by optical coherence tomography (OCT), is associated with nAMD and DME. Reductions in central retinal subfield thickness (CST) were observed across all treatment arms. 12.
