Frequently asked questions

About HAE

What is hereditary angioedema (HAE)?

HAE is a rare, inherited disease that results in C1 esterase inhibitor (C1-INH) deficiency, the primary regulator of inflammation and vascular permeability. As a result of the deficiency, people living with HAE develop acute, recurrent episodes of localized edema, which may occur in the extremities, abdomen, face, and throat, and which can be fatal if not properly treated.4

Learn about diagnosing HAE

How can I differentiate between HAE and conditions that present with similar symptoms?

HAE is often misdiagnosed because the symptoms mimic those of several common conditions, including allergic angioedema.4

It’s important to determine the difference between GI problems, allergic angioedema, and HAE because the pathophysiology and the treatment of the diseases are different.

HAE can be confirmed with blood tests to evaluate C4 serum concentration and C1-INH function.13

Which types of HAE does BERINERT treat?

BERINERT treats the two most common types of HAE (Type I and Type II).

Type I: The body does not produce enough C1 esterase inhibitor (C1-INH). Approximately 85% of people living with HAE have type I.4

Type II: The body produces C1-INH that does not function correctly. Approximately 15% of people living with HAE have type II. 4

BERINERT is not indicated for treating HAE with normal C1-INH. This is a very rare form of HAE that occurs despite normal C1-INH levels and/or function.

How does BERINERT treat HAE?

Patients with HAE experience angioedema attacks because they lack functioning C1 esterase inhibitor (C1-INH).4 BERINERT addresses the root cause of HAE attacks by replacing missing or dysfunctional C1-INH to stop attacks.

BERINERT is the only C1-INH approved for on-demand treatment of acute abdominal, facial, or laryngeal attacks of HAE in adults and pediatrics.

BERINERT is an intravenous infusion that patients can self-administer after proper training by a healthcare professional.

How fast does BERINERT provide relief?

BERINERT provides fast onset of relief from HAE attacks in as little as:

  • 15 minutes for laryngeal attacks*
  • 48 minutes for abdominal/facial attacks*
*Median time to complete resolution of HAE symptoms was 4.9 hours in a phase 3 clinical trial and 8.4 hours in an open-label extension.

How does on-demand treatment benefit my patients?

On-demand treatment helps patients take control of their HAE by treating at the first sign of an HAE attack, which can occur suddenly, frequently, and without warning.

Because attacks can occur even in patients on prophylactic HAE therapy, the WAO Guidelines for the Management of HAE state that patients should have on-demand medication available at all times.13

Has the safety of BERINERT been evaluated in pediatric patients?

Yes. A US-European Registry Study (N=18, age range 5–11 years) demonstrated safety similar to that observed in adults.

Safety and efficacy were also evaluated in placebo-controlled and open-label extension studies (N=12, age range 10–16 years).

What were the adverse reactions in the clinical trials?

No serious adverse events or adverse events leading to discontinuation of treatment occurred within 4 hours after study treatment.1

Adverse reactions occurring up to 4 hours after initial infusion in more than 4% of subjects, irrespective of causality, included nausea, dysgeusia, and abdominal pain.*

*The following abdominal symptoms were identified in the protocol as associated with HAE abdominal attacks: abdominal pain, bloating, cramps, nausea, vomiting, and diarrhea.

What is the recommended BERINERT dosage?

BERINERT offers a weight-based approach to provide an individualized dose of C1-INH during an attack.

The recommended BERINERT dosage is 20 units (IU) per kilogram body weight, with a recommended infusion rate of 4 mL/minute. For example, a 70-kg patient would require 1400 IU, infused over 7 minutes.
