Usage of Lanadelumab

Lanadelumab (Takhzyro) is a monoclonal antibody that works by reducing the activity of an enzyme that is uncontrolled in people with hereditary angioedema (a rare genetic immune system disorder). Lanadelumab is used to prevent attacks of hereditary angioedema (HAE) in patients who are 2 years of age and older.

People with hereditary angioedema have high levels of a substance called bradykinin, lanadelumab works by reducing the level of bradykinin, which helps to prevent the swelling and related symptoms of angioedema. Hereditary angioedema is an immune system condition that causes rapid swelling under the skin in areas such as the face, throat, arms, and legs. An attack of hereditary angioedema can be life-threatening if the swelling around the throat presses against the airway.

Lanadelumab-flyo (Brand name: Takhzyro) injection is FDA approved for patients who are 2 years of age and older to prevent attacks of hereditary angioedema. FDA approval was supported by data from HELP Study, the  HELP OLE Study and the Phase 3 SPRING Study (NCT SHP643-301).
