ricans and is caused by a deficiency of C1-INH, which is inherited in an autosomal dominant manner. Patients who have abdominal attacks can experience episodes of severe pain, diarrhea, nausea, and vomiting caused by swelling of the intestinal wall. Attacks that involve the face and larynx can result in airway closure, asphyxiation, and, if untreated, death. Diagnosis of HAE requires a blood test to confirm low or abnormal levels of C1-INH.

About I.M.P.A.C.T. 2

Findings of I.M.P.A.C.T. 2 were based on treatment with 20 U/kg bodyweight of C1-INH in 640 episodes of HAE attacks at any body location in 57 patients. The main study end-points were: time to onset of symptom relief; complete resolution of all symptoms, and safety.

The median time to the onset of symptom relief was 16 minutes for laryngeal attacks, 23 minutes for abdominal attacks, 28 minutes for facial attacks and 31 minutes for peripheral attacks, such as attacks in the hands and feet. The median times to complete resolution of all symptoms were reported as early as 8 hours for laryngeal attacks, 11 hours for abdominal, 24 hours for facial and 25 hours for peripheral attacks. No drug-related serious adverse events have been reported to date, nor were any rebound effects observed following C1-INH administration.
