How does NUCALA work?

NUCALA targets eosinophils, but what exactly does that mean?

What are eosinophils?

Eosinophils [ee-uh-sin-uh-fils] are white blood cells that are a normal part of the body’s immune system.

How do elevated eosinophils play a role in EGPA?

When you have EGPA, your blood eosinophil count is elevated. Elevated eosinophils in your blood can lead to inflammation.

NUCALA specifically targets eosinophils

NUCALA is not a steroid like prednisone. It reduces the number of eosinophils in the blood.

It is not fully understood how NUCALA works.
