Study Participants

Who will be able to join the PrecISE asthma study:

The PrecISE study centers will recruit up to 650 adults and 150 teenagers (ages 12 years and older). The study participants should meet the criteria for severe asthma that is not well-controlled or with frequent asthma attacks. The participant should also be on a stable treatment. People will be recruited from over 30 sites in the US.

What participants will do in the PrecISE asthma study:

As a part of PrecISE research, participants will be assigned a treatment that targets their type of severe asthma. The type of severe asthma will be determined using biomarkers. Biomarkers are bits of information about someone based on data gathered from tests, including blood tests. The likelihood for a participant to receive a therapy will change based on new data that will be collected during the study. Adult participants in PrecISE research may receive at least three treatments, and up to six treatments. Adolescents may receive up to three treatments. 

How PrecISE is different from other studies in severe asthma:

PrecISE will research new treatments in groups of patients characterized by their bodies' specific disease pathways in order to research treatments for each group. PrecISE will include participants with severe asthma to research new treatments.

Why is PrecISE important?

Current asthma medicines often don’t work well for people who have severe asthma.

Even when taking these medicines, people with severe asthma often continue to have daily symptoms (difficulty breathing, wheezing, chest tightness) and a greater risk of asthma attacks.

What medicine will I take?

If you decide to take part in the study, you will be assigned a treatment for your specific type of severe asthma. It is likely that your medicine will change during the study based on how well your body responds to it.

Adults in the PrecISE study will receive between 2 and 5 different treatments over the course of the study. Teens will receive up to 3 different treatments.

If you join the study:

- You will answer questions about your medical history, asthma symptoms, and quality of life

- Some visits include other tests, like physical exams, blood and urine tests, breathing tests, and a chest CT scan 

- You will also have in-between visit tasks to do at home (e-diary, home breathing tests)

Why should I join?

- Although there is no guarantee, participants may benefit from the study treatment and/or information gained from study tests.

- All study tests and exams, including asthma medications, are at no charge to you.

- Research findings based on this study may lead to better ways of treating people with severe asthma.

Taking part in the PrecISE Study is voluntary. If you decide to join, you will be compensated for your time. You can withdraw from the study at any time.
