Carrageenan-induced rat paw oedema: dose-dependent inhibition, max 73% (SC) at 30 mg/kg
“Lanadelumab pretreatment was found to inhibit carrageenan induced rat oedema in a dose-dependent manner with a maximum inhibition at 30 mg lanadelumab/kg by 73% following SC and 62% following IV infusion, respectively, suggesting an inhibition of pKal functional effects in vivo.”
No established nonclinical animal model of HAE; bradykinin-mediated rat paw oedema used for mechanism
“Due to the lack of established non-clinical animal models of HAE, the in vivo pharmacodynamics of lanadelumab was evaluated in the carrageenan-induced rat paw oedema model, in which bradykinin is a known proinflammatory mediator, and that can be used to access mechanistic aspects of pKal inhibition.”
EMA: model shows activity but is not an HAE model; appropriately not used to predict clinical doses
“This demonstrated the activity of lanadelumab, however, as the rat carrageenan paw oedema model is not a non-clinical model of HAE, efficacious doses in this model were not used to predict clinical efficacious doses, which is considered appropriate.”
