What is PrecISE?

PrecISE is a research study to understand how to treat different types of severe asthma. PrecISE will study adults and adolescents with severe asthma. We are looking for people who have asthma attacks or frequent asthma symptoms. Everyone in the study will receive medicine that is based on the type of severe asthma they have.

This study is sponsored by the U.S. National Heart, Lung, and Blood Institute.
