Pharmaceutical Information

• Pharmacodynamics: In phase 1 studies, the level of kininogen, the substrate of kallikrein, was studied as a marker of kallikrein activity. In patients with C1 deficiency, the level of cleaved kininogen is 4-fold higher when compared with C1-normal individuals. When lanadelumab was administered, the levels of cleaved kininogen were significantly reduced with a dose of 300 and 400 mg of lanadelumab with a maximum reduction at day 22 corresponding with time for maximum concentration. This maximum reduction corresponded with the normal levels of cleaved kininogen. Similarly, the decreases of cleaved kininogen corresponded with reductions in the levels of the activated factor XII. Clinically, the attacks of angioedema completely vanished in the patients receiving a dose of 300 mg of lanadelumab. In other doses such as 400 mg and combo 300/400 mg the attack reduction reached 90%. In phase 3 clinical trials, lanadelumab showed an attack rate reduction of over 70% for all studied regimens.
• Targets: Plasma kallikrein
