Participants must be 12 to 80 years of age inclusive at the time of signing the informed consent/assent form with a physician diagnosis of asthma for ≥12 months, based on the Global Initiative for Asthma (GINA) 2023 guidance document
Note: Other protocol-defined Inclusion criteria apply
Existing treatment with medium dose ICS/LABA (>250 to 500 μg/day of fluticasone propionate DPI (dry powder inhaler) or equivalent, per GINA 2023 guidance document) for at least 3 months with a stable dose ≥1 month prior to visit 1
Participants requiring a maximum of 3 controllers for their asthma will be considered eligible for this study
Pre-bronchodilator FEV1, as defined in the protocol
Reversibility of at least 12% and 200 mL in FEV1 after the administration of 200 to 400 μg albuterol/salbutamol at screening OR a documented history of ≥20% reduction in the FEV1, as defined in the protocol
Demonstrated adherence to medium dose ICS/LABA on at least 80% of days during the run-in period
ACQ-5 score ≥1.5 at screening (visit 1)
History of ≥1 severe exacerbation(s) in the previous year before visit 1, but not in the 30 days immediately preceding visit 1
Biomarker criteria: Baseline blood eosinophil count ≥300 cells/μL at visit 1 (~90% of population), as defined in the protocol
Diagnosis of chronic obstructive pulmonary disease (COPD) or other lung diseases which may impair lung function and interfere with treatment assessments
Clinical evidence of lung disease(s) other than asthma or imaging (Chest X-ray, computed tomography [CT], magnetic resonance imaging [MRI]) with significant findings within 12 months of visit 1 and up to and including the baseline visit (visit 3)
A participant who experiences a severe asthma exacerbation at any time from 1 month prior to the screening visit (visit 1) up to and including the baseline visit (visit 3), as defined in the protocol
Weight is less than 30 kilograms
Current smoker or cessation of smoking within 6 months prior to visit 1 or previous smoker with a smoking history ≥10 pack-years
Severe concomitant illness(es) that, in the Investigator’s judgment, would adversely affect the participant’s participation in the study, as defined in the protocol
Participants cannot be on systemic corticosteroids at any time from 1 month prior to the screening visit (visit 1) through the duration of the run-in period
Note: Other protocol-defined Exclusion criteria apply
