C1-inhibitor (C1-H) belongs to the superfamily of serine protease inhibitors. C1-inhibitors controls the activation of the C1 complex. It forms a proteolytically inactive stoichiometric complex with the C1r or C1s proteases. It also plays an important role in regulating important physiological pathways including complement activation, blood coagulation, fibrinolysis, and generation of kinins. It is the most efficient inhibitor of FXIIa factors and also inhibits chymotrypsin and kallikrein.
Market Dynamics
Hereditary angioedema (HAE) is the disease condition characterized by the C1 esterase inhibitor deficiency. According to reported data by National Center for Biotechnology Information in 2013, the estimated prevalence of HAE in the general population is between 1 in 10,000 and 1 in 150,000 individuals worldwide. Cinryze, a pharmaceutical-grade C1-inhibitor, was approved by U.S.FDA for the treatment of HAE in 2008. Cinryze is a highly purified, pasteurized and nanofiltered plasma-derived C1 esterase inhibitor product; it has been approved for routine prophylaxis against angioedema attacks in adolescent and adult patients with HAE. Thus, the increasing trend of using plasma-derived C1 esterase inhibitor products in HAE treatment is expected to drive growth of the global plasma protease C1-inhibitor treatment market.
