: Participant of 12 years of age or older at the time of signing the informed consent or written informed consent is obtained from each study participant's legal guardian.
Asthma for ≥ 6 months, defined as
documented history of asthma, as defined by Global Initiative for Asthma (GINA) (GINA, 2023].
Receiving one of the following asthma treatments, at a stable dose, for at least 12 weeks prior to the screening visit, with treatment that is anticipated to remain stable for the duration of the study:
Receiving one of the following asthma treatments, at a stable dose, for at least 12 weeks prior to the screening visit, with treatment that is anticipated to remain stable for the duration of the study: daily maintenance low to medium dose Inhaled corticosteroid (ICS) (low to medium dose ICS defined as 100-500 μg/day fluticasone propionate or equivalent as defined in the 2023 GINA guidelines [GINA, 2023], plus Short-Acting Beta-2-Adrenoreceptor Agonists (SABA), which is anticipated to remain stable for the duration of the study.
Receiving one of the following asthma treatments, at a stable dose, for at least 12 weeks prior to the screening visit, with treatment that is anticipated to remain stable for the duration of the study: daily maintenance low to medium dose ICS/ Long-acting bronchodilator (LABA) (low to medium dose ICS defined as 100-500 μg/day fluticasone propionate or equivalent as defined in the GINA guidelines [GINA, 2023] plus SABA, which is anticipated to remain stable for the duration of the study.
Participants who utilize combination budesonide/formoterol (e.g., Symbicort) as reliever therapy, whether or not this is in addition to a SABA - are not eligible for screening.
Participants who utilize ICS/SABA combination therapy as reliever therapy, in addition to low to medium dose ICS or ICS/LABA as maintenance, are only eligible if they agree to discontinue their ICS/SABA inhaler for the duration of the study (screening through follow-up).
Severity of disease assessed by the investigator by baseline pre-bronchodilator Forced expiratory volume in 1 second (FEV1).
Asthma Control Status:
Asthma Control Questionnaire (ACQ) 6 score <1.5 at screening.
Asthma Control Status: Asthma that has remained stable with no severe exacerbations in the last 6 months. Severe exacerbation defined as
deterioration of asthma-requiring the use of systemic corticosteroids (tablets, suspension or injection), for at least 3 days, OR
an inpatient hospitalization or Emergency Department (ED) visit because of asthma, requiring systemic corticosteroids.
Reversibility of disease evaluated by pulmonary function testing.
Participants should be able to withhold SABA for ≥6 hours and LABA-containing medications for ≥24 hours for the purposes of performing screening spirometry.

: A history of life-threatening asthma or asthma that is unstable in the opinion of the investigator.
Other significant pulmonary diseases to include (but not limited to): pneumothorax, pulmonary fibrotic disease, bronchopulmonary dysplasia, chronic bronchitis, emphysema, chronic obstructive pulmonary disease, tuberculosis or other respiratory abnormalities other than asthma.
Respiratory Infection: Culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract, sinus or middle ear that is not resolved within 4 weeks of screening that led to a change in asthma management, OR in the opinion of the Investigator, is expected to affect the participant's asthma status, OR the participant's ability to participate in the study.
Asthma Exacerbation: Any severe asthma exacerbation within 6 months prior to screening.
Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
Long-acting muscarinic antagonist (LAMA) during the 3 months prior to the start of the study.
Biologic/immunosuppressive therapies used for the treatment of respiratory diseases during the 6 months, or 5 half-lives-whichever is longer-prior to start of the study.
