Background:
  • Hereditary angioedema (HAE) is a disease that presents with episodes of non-allergic angioedema. Patients experience swelling episodes that resolve within 2 to 5 days without treatment; however laryngeal swelling can be fatal. The swelling occurs without hives or itching. Bradykinin is a vasodilator that results in the swelling that is associated with angioedema. Since the angioedema is non-allergic, histamines are not involved and antihistamines are not effective. HAE can also occur because of a deficiency or malfunction of the C1 inhibitor in the body which regulates the coagulation pathway. There are three types of HAE. HAE type I is caused by a deficiency in C1 inhibitor, HAE type II is caused by a dysfunction of C1 inhibitor, HAE type III also known as Hereditary with Normal C1 inhibitor is a type not caused by C1 inhibitor deficiency.
  • Berinert is indicated for the treatment of acute abdominal, facial, or laryngeal attacks of hereditary angioedema in adult and pediatric patients. Berinert was tested in 124 adult patients in a placebo-controlled double blind trial with the primary objective of shortening the time to onset of relief of symptoms. Patients who received Berinert were shown to have a reduction in time to onset of relief with a median of 48 minutes for the Berinert group compared to 4 hours in the placebo group.
  • Cinryze is a medication indicated for routine prophylaxis against angioedema attacks. The efficacy of Cinryze was evaluated in a placebo controlled trial. 24 patients were randomized to receive Cinryze for 12 weeks followed by placebo for 12 weeks or to receive placebo for 12 weeks followed by Cinryze for 12 weeks. The average number of attacks was 6.1 while patients were receiving Cinryze compared to 12.7 while patients were on placebo.
  • Firazyr was studied in a randomized, placebo-controlled, double-blind clinical trial with 98 adult patients. The median time to reduction in symptoms was significantly lower in the Firazyr group compared to 19.8 hours in the placebo group.
  • Haegarda is indicated for routine prophylaxis to prevent angioedema attacks in adolescents and adults. The clinical efficacy was demonstrated in a multicenter, randomized, double-blind, placebo-controlled, crossover study. The primary efficacy endpoint was the difference in the time-normalized number of HAE attacks (the rate of attacks) relative to placebo. Patients were randomized to receive either 60 IU/kg or 40 IU/kg of C1-INH [Human] (Haegarda) for 16 weeks and placebo in the other 16 week treatment period. Patients who were in the Haegarda 60 IU/kg demonstrated a reduction of 3.5 attacks per month.
  • Ruconest is indicated for the treatment of acute attacks in patients with hereditary angioedema. Ruconest was studied in a placebo-controlled, double-blind, randomized study with the primary outcome of looking at the time to relief of symptoms. The median time to relief of symptoms was significantly lower in the Ruconest group than in the placebo group. Note, the effectiveness of Ruconest was not established in HAE patients with laryngeal attacks.
  • Takhzyro (lanadelumab-flyo) is indicated for prophylaxis to prevent attacks of hereditary angioedema (HAE) in patients 12 years of age and older. The primary endpoint was the number of investigator-confirmed HAE attacks over the entire 26-week study duration. The trial demonstrated a mean monthly reduction of number of attacks in all treatment groups. In the pivotal study, patients taking Takhzyro 300 mg every 2 weeks had an 87% reduction in mean monthly attacks vs. placebo
