Lanadelumab  (Synonyms: SHP643; DX-2930)

Lanadelumab (SHP643) is a human IgG1 monoclonal antibody against plasma kallikrein (pKal) with an K_i value of 0.12 nM. Lanadelumab inhibits both free and HMWK (high molecular weight kininogen)-bound pKal. Lanadelumab has the potential for the research of hereditary angioedema^[1][2].

Lanadelumab (0-1000 nM) inhibits pKal proteolytic activity of single-chain HMWK (its endogenous protein substrate), and addition of Lanadelumab to pKal samples in vitro preventes the proteolysis of HMWK and the consequent release of bradykinin with an IC₅₀ value of 1.3 nM^[2].

Lanadelumab (20 mg/kg; i.v. or s.c.) shows a long half-life of about 12.5 days and blocks high molecular weight kininogen proteolysis in activated plasma in a dose- and time-dependent manner in cynomolgus monkeys^[2].
Lanadelumab (1, 30 mg/kg; s.c.) inhibits carrageenan-induced paw edema in the Male Sprague-Dawley rats ^[2].
