Denosumab does not recognize rodent RANKL; huRANKL knock-in mice expressing chimeric RANKL used for rodent studies
“Denosumab is a fully human IgG2 mAb and does not recognize rodent RANKL. Several studies have been conducted with a transgenic huRANKL knock-in mouse model expressing chimeric RANKL that can be recognized and neutralized by denosumab.”
EMA: preclinical studies characterized pharmacology and demonstrated activity in vitro and in vivo
“Overall the preclinical studies characterized the pharmacological, pharmacodynamic and toxicological properties of denosumab and demonstrated its activity in vitro and in vivo.”
