The kallikrein-kinin pathway is dysregulated in HAE1
Uncontrolled plasma kallikrein leads to excessive bradykinin production2
Figure adapted from Valerieva et al, Bender et al, and Csuka et al.3-5
C1-INH=C1 esterase inhibitor; cHMWK=cleaved high molecular weight kininogen; FXII=factor XII; FXIIa=factor XIIa; HMWK=high molecular weight kininogen; PKa=activated plasma kallikrein.
An established mAb targeting the inhibition of plasma kallikrein to reduce the release of bradykinin1
TAKHZYRO provides targeted inhibition of plasma kallikrein, a critical regulator of bradykinin, known to cause HAE attacks1
