Why that species
High sequence homology (83-98%) to human ANGPTL3 and evinacumab target binding in monkey, rabbit and rat
“The cynomolgus monkey, rabbit, and rat are pharmacologically relevant species for toxicologic evaluation of evinacumab considering the high sequence homology (83-98%) to human ANGPTL3 and evinacumab target binding data”

Species: DART
Rat (female fertility/pre- and postnatal, EFD), rabbit (EFD, male fertility) and monkey fertility endpoints in 26-week study
“The reproductive toxicity of evinacumab was assessed using male and female fertility endpoints collected from the chronic 26-week monkey toxicity study, and by conducting combined female fertility/early embryonic/pre and postnatal development study in rats, embryofetal development studies in rats and rabbits, and a male fertility and paternally-mediated EFD study in male rabbits.”

Species: carcinogenicity
Not conducted (weight-of-evidence assessment accepted)
“No in vivo animal carcinogenicity studies were requested by the Division after consulting with CDER’s Executive Carcinogenicity Assessment Committee (April 18, 2017) and the sponsor’s carcinogenicity assessment is considered adequate.”
