How does NUCALA work?2

NUCALA targets eosinophils, but what exactly does that mean?

eosinophil cell

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 eosinophils play a role in severe asthma?

Having too many eosinophils in your blood can damage the airways and can cause your asthma to get worse or can increase the number of your asthma flare ups.

NUCALA reduces eosinophils

NUCALA is not a steroid like prednisone. It is designed to reduce the number of eosinophils in your blood.

The mechanism of action of NUCALA is not fully understood.

Reducing the number of eosinophils in your blood may help reduce airway inflammation.

NUCALA helps you gain asthma control and helps reduce your use of oral steroids like prednisone. It's important to receive your injection of NUCALA once every four weeks as prescribed, even if you're feeling better.

Results may vary.

A simple blood test can measure the number of eosinophils in your blood

Your doctor can give you a blood test that measures your eosinophil count or refer you to a specialist who will review your asthma with you and request the relevant blood tests. Based on the test results, your specialist will consider whether adding NUCALA to your treatment plan is the right fit for you. In clinical studies, the eosinophil blood test helped identify patients whose asthma was more likely to respond to treatment with NUCALA.1
