GtoPdb Ligand ID: 8717

Synonyms: REGN1500
Compound class: Antibody
Comment: Evinacumab is a fully human investigational monoclonal antibody targeting angiopoietin-like 3 (ANGPTL3). Due to its role in lipid metabolism, ANGPTL3 is being investigated as a potential molecular target for the treatment of hypertriglyceridemia in cardiovascular disease.
Peptide sequence and structural information for this antibody are available from its IMGT/mAb-db record.
A BLAST search of patented peptide sequences reveals that the heavy chain variable domain of evinacumab is identical to SEQ ID: NO 66 from patent US9018356 B2 [3], and the light chain variable region is identical to SEQ ID: NO 74 from the same patent (this heavy/light chain combination corresponds to antibody identifier H4H1276S).
No information available.

Mechanism Of Action and Pharmacodynamic Effects
ANGPTL3 inhibits lipoprotein lipase (LPL) activity leading to increased level of lipids [1], and subsequently regulates very low density lipoprotein (VLDL) triglyceride levels [2]. The N-terminal coiled-coil region of ANGPTL3 inhibits LPL when expressed without the C-terminal fibrinogen region and therefore appears to confer its inhibitory function. The H4H1276S antibody clone in patent US9018356 B2, presumed to be evinacumab, inhibits the ANGPTL3-induced decrease in LPL activity in vitro [3], but does not block ANGPTL4-induced decrease in LPL activity. H4H1276S shows cross-species activity, inhibiting mouse and monkey ANGPTL3 at comparable levels to the human protein [3].
