Lanadelumab (SHP643) is a humanized IgG1 monoclonal antibody targeting plasma kallikrein (pKal) with a Ki value of 0.12 nM. Lanadelumab effectively inhibits both free pKal and its interaction with high molecular weight kininogen (HMWK)-bound pKal. Lanadelumab has demonstrated potential in hereditary angioedema research and represents a promising therapeutic antibody for studying kallikrein-kinin system regulation.

| In vitro | Lanadelumab (0-1000 nM) inhibits the proteolytic activity of pKal toward its endogenous substrate, single-chain HMWK. Furthermore, in vitro studies demonstrate that Lanadelumab potently prevents HMWK proteolysis and the subsequent release of bradykinin, with an IC50 of 1.3 nM.[2] |
| In vivo | Lanadelumab (20 mg/kg; i.v. or s.c.) exhibits an extended half-life of approximately 12.5 days and effectively blocks high molecular weight kininogen proteolysis in activated plasma in a dose- and time-dependent manner in cynomolgus monkeys. Additionally, Lanadelumab (1, 30 mg/kg; s.c.) significantly inhibits carrageenan-induced paw edema in male Sprague-Dawley rats.[2] |
