Garadacimab (CSL312) is a first-in-class, fully human IgG4 monoclonal antibody targeting activated factor XII (FXIIa). Garadacimab has the potential for hereditary angioedema research.

Garadacimab (CSL312) displays high affinity to activated βFXIIa with a K_D of 140 pM and shows potency in an activated partial thromboplastin time (aPTT) assay with human plasma. Garadacimab shows high selectivity over a panel of relevant human serine proteases (FVIIa, FIXa, FXa, FXIa, kallikrein, tissue plasminogen activator, activated protein C, and urokinase plasminogen activator).

In male and female cynomolgus monkeys, Garadacimab (0.5, 1, and 3 mg/kg i.v. and 6 and 20 mg/kg s.c. over 8 weeks) plasma concentrations increased in a dose-dependent manner.
Garadacimab has an inhibitory effect on FXII-mediated kallikrein activity. Furthermore, Garadacimab causes a clear dose-dependent prolongation of activated partial thromboplastin time (aPTT) with no associated effect on the prothrombin time.
