Inclusion criteria

Inclusion criteria: 1. Documented history of physician-diagnosed asthma > and/or = 1 year prior to V1. 2. Documented history of at least one asthma exacerbation requiring use of systemic corticosteroids (SCS) (oral or IV) ) and any combination thereof for at least 3 consecutive days and an associated physician visit, hospitalization, or emergency room visit due to asthma (within 3 days of the corticosteroid use) in the 12 months prior to V1 (Not applicable to adolescents). 3. 12 to 80 years of age, male and female, BMI and/or = 18 years of age: Increase > and/or = 12% and > and/or = 200 mL. • Participants 12 to and/or = 18 years of age: and/or = 1.5 at V1, 3, 5. 7.
