Participants on existing therapy with medium to high doses of ICS (≥500 μg fluticasone propionate daily or comparable ICS dose in combination with at least one additional controller (e.g., long-acting beta agonist \[LABA\], leukotriene receptor antagonist \[LTRA\], long-acting muscarinic antagonist \[LAMA\], methylxanthines) for at least 3 months.
≥ 1 severe asthma exacerbation in the past year, with at least one exacerbation during treatment with medium to high doses of ICS (≥ 500 μg fluticasone propionate daily or one dose of ICS comparable).
Participants with pre-BD forced expiratory volume in 1 second (FEV1) \> 40% and \< 80% of predicted normal at the screening visit.
5-item ACQ-5 score \>1.5 at randomization.
Participants with at least 12% reversibility and 200 mL post-BD FEV after administration of albuterol/salbutamol or levalbuterol/levosalbutamol at screening or documented history of a reversibility test.

Suspicion of, or confirmed, coronavirus disease 2019 (COVID-19) infection during the screening period including known history of COVID-19 infection within 4 weeks prior to Screening; mechanical ventilation or extracorporeal membrane oxygenation (ECMO) secondary to COVID-19 within 3 months prior to Screening; COVID-19 infection who have not yet sufficiently recovered to participate in the procedures of a clinical trial.
Active infection or history of clinically significant infection
Known history of, or suspected, significant current immunosuppression, including history of invasive opportunistic or helminthic infections despite infection resolution or otherwise recurrent infections of abnormal frequency or prolonged duration.
