Berotralstat, sold under the brand name Orladeyo, is a medication used to prevent attacks of hereditary angioedema (HAE).[1] It is used in people aged twelve years and older.[1] It is taken by mouth.[1]

Common side effects include abdominal pain, vomiting, diarrhea, back pain, and heartburn.[1] Other side effects may include QT prolongation.[1] While there is no evidence of harm in pregnancy, such use has not been well studied.[1] It is a plasma kallikrein inhibitor.[1]

Berotralstat was approved for medical use in the United States in 2020 and Europe in 2021.[1][2] In the United Kingdom 4 weeks costs the NHS about £10,200 as of 2022.[5] This amount in the United States costs about 40,500 USD.[6]

Medical uses

It is used to prevent attacks of hereditary angioedema (HAE).[1] It decreases the rate of attacks from about 2.4 per month on placebo to 1.3 with treatment.[2]

Dosage

It is generally taken at a dose of 150 mg once per day.[1]

History

Berotralstat was approved based on evidence from one clinical trial (Trial 1 /NCT03485911) of 120 participants with hereditary angioedema.[4] The trial was conducted at 40 sites in the United States, the European Union, and Canada.[4] Trial investigators evaluated participants 12 years and older[7] with hereditary angioedema for eight weeks to determine the number of attacks for each participant.[4] The trial enrolled only participants who had at least two attacks during the eight-week period.[4] Participants were assigned to receive one of two doses of berotralstat or placebo once every day for 24 weeks.[4] Neither the participants nor the investigators knew which treatment was being given until after the trial was completed.[4] All participants could use other medications for treatment of attacks.[4]
