What is Ecallantide

Ecallantide, a novel Kunitz domain produced by phage display (a powerful method of generating novel binders to potentially therapeutic targets), is a potent and selective inhibitor of plasma kallikrein which demonstrates a useful efficacy/safety ratio in the treatment of acute attacks of HAE (Hereditary Angioedema). On November 27, 2009, ecallantide was approved by the FDA for the treatment of acute attacks of hereditary angioedema for persons over 16 years of age.

Ecallantide mechanism of action

HAE is caused by a mutation of the C1-inhibitor gene. Defective or missing C1-inhibitor permits activation of kallikrein, a protease that is responsible for liberating bradykinin from its precursor kininogen. An excess of bradykinin leads to fluid leakage from blood vessels, causing swelling of tissues typical of HAE. Ecallantide suppresses this pathogenetic mechanism by selectively and reversibly inhibiting the activity of plasma kallikrein.

Toxicity of Ecallantide

While there have been no reports of overdose with ecallantide, patients with hereditary angioedema have received single doses up to 90 mg intravenously without evidence of dose-related toxicity. There are no animal or human studies to assess the carcinogenic or mutagenic potential of ecallantide. In rats receiving subcutaneous doses up to 25 mg/kg/day, there were no observable effects on fertility reproductive performance. An approximate lethal dose was identified as 25 mg/kg intravenously in rats and 5 mg/kg intravenously in rabbits.
