Evinacumab in hyperlipidemic mouse models (ApoE-/-, Ldlr-/-, db/db, high-fat diet) and normolipidemic mice
“Evidence of pharmacodynamic activity of evinacumab was established following single and multiple dose (8 week) SC administration in normolipidemic (C57BL/6) and multiple hyperlipidemic (ApoE-/- , Ldlr-/- , db/db and high-fat diet fed) mouse models”

Why that model
Evinacumab binds human, mouse, rat and monkey ANGPTL3 with high affinity (KD 0.3-1.3 nM)
“In vitro, evinacumab binds the N-terminal domain of ANGPTL3 proteins containing LPL binding regions from humans, mice, rats, and monkeys with high affinity (sub to low-nanomolar KD values ranging from 0.3 to 1.3 nM).”

Reviewer's view of the efficacy data
FDA: TG and HDL-C pathways well characterized; exact mechanism of LDL-C lowering less clear
“While the pathways contributing to TG and HDL-C reduction with ANGPTL3 inactivation are well characterized, the exact mechanism responsible for evinacumab-mediated LDL-C lowering is less clear.”
