What is HAE

HAE is a rare genetic condition which occurs in approximately 1 in 30,000 people worldwide. Symptoms include episodes of swelling in the hands, feet, abdomen, face and airway. Patients may suffer bouts of excruciating abdominal pain, nausea and vomiting that is exacerbated by swelling in the intestinal wall. Airway (laryngeal) swelling is particularly dangerous and can lead to death by asphyxiation. Untreated, attacks can last between 48 and 120 hours and can be fatal. Additional information about the condition can be found on the international HAE patient’s association website at

Medical need

C1 esterase inhibitor (C1INH) is a protein that naturally occurs in the human body. It belongs to the class of serine-protease inhibitors or serpins. It regulates several inflammatory pathways in the body by inhibiting certain proteins (proteases) that are part of the human immune system. Deficiency of functional C1 inhibitor leads to excessive activation of the complement system and other immunological and haemostatic pathways, giving cause to angioedema attacks. These attacks are characterised by acute and painful swellings of soft tissues. Administration of C1 inhibitor protein can normalize the low C1 INH levels and stop the angioedema attacks.
