How NUCALA Works
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.
Eosinophils play a role in nasal polyps
When you have CRSwNP there is inflammation in your nasal passages. Eosinophils, a type of white blood cell, play an important role in this inflammation. Because surgery doesn’t eliminate this inflammation, the nasal polyps can come back.
Nasal polyps coming back?
Most nasal polyps have high numbers of eosinophils*
Nasal polyps with high eosinophils have a greater chance of returning after surgery.
*In addition to other types of cells.
NUCALA specifically targets eosinophils
NUCALA is not a steroid, like prednisone; it's a biologic. NUCALA is the first approved treatment that specifically targets eosinophils, a source of inflammation in nasal polyps. It reduces the number of eosinophils in the blood.
It is not fully understood how NUCALA works.
