About RUCONEST® and Hereditary Angioedema
RUCONEST® (INN conestat alfa) is a recombinant version of the human protein C1 inhibitor (C1INH). RUCONEST is produced through Pharming's proprietary technology in milk of transgenic rabbits and is approved in Europe for treatment of acute angioedema attacks in patients with HAE. RUCONEST® is an investigational drug in the U.S. and has been granted orphan drug designation for the treatment of acute attacks of HAE, a genetic disorder in which the patient is deficient in or lacks a functional plasma protein C1 inhibitor, resulting in unpredictable and debilitating episodes of intense swelling of the extremities, face, trunk, genitals, abdomen and upper airway. The frequency and severity of HAE attacks vary and are most serious when they involve laryngeal edema, which can close the upper airway and cause death by asphyxiation. According to the U.S. Hereditary Angioedema Association, epidemiological estimates for HAE range from one in 10,000 to one in 50,000 individuals.
