## Popular FAQ

## How effective is Orladeyo for HAE?

In research studies that led to approval, Orladeyo significantly reduced HAE attacks at 6 months (24 weeks) time and led to a sustained reduction through 48 weeks. For patients in the studies, HAE attacks declined from an average of 2.9 attacks per month to 1 attack per month after about one year of treatment.

## Is Orladeyo an orphan drug?

Orladeyo (berotralstat) is an orphan drug. The US Food and Drug Administration (FDA) granted Orladeyo orphan drug designation in November 2017 for the treatment of C1-inhibitor-dependent angioedema (including prevention and treatment of attacks).

Orladeyp is a plasma kallikrein inhibitor, which was approved by the FDA in 2020 for prophylaxis to prevent attacks of hereditary angioedema (HAE) in adults and pediatric patients 12 years and older.

Orladeyp is marketed by BioCryst Pharmaceuticals, which has marketing exclusivity for this drug until December 2027.

Orphan drugs are drugs that are used to treat orphan or rare diseases. The FDAs orphan drug designation process provides companies with various incentives to develop therapeutics for the treatment of rare disease.

## How does Orladeyo work?

Orladeyo (berotralstat) works by blocking the action of a protein in your blood called kallikrein. High kallikrein activity in people with hereditary angioedema (HAE) increases bradykinin, a chemical that leads to pain and swelling. Orladeyo is a once-daily oral, prescription medicine used to prevent attacks of HAE in adults and children 12 years and older.
