Sex: All

Target Recruitment: 38

Inclusion Criteria

- Participants who are diagnosed with asthma with documented reversibility post-bronchodilator or salbutamol either historical or at Visit 0 (V0).
- Participants who have documented treatment with ICS and LABA for = 3 months prior to V0 with or without oral corticosteroids and additional asthma controllers.
- Participants who have documented peripheral blood eosinophil count = 300 cells/µL at V0, or if Oral Corticosteroids (OCS)-dependent, a documented peripheral blood eosinophil count = 150 cells/µL at V0.
- Participants who have had a minimum of 2 exacerbations in the last 12 months prior to V0.

- Participants who have pre-bronchodilator FEV1/FVC = 70% at Visit 0 (V0).
- Participants who have pre-bronchodilator Forced Expiratory Volume in 1 second (FEV1) < 80% of predicted at V0.
- Participants who have stable asthma regimen apart from the use of rescue medication including the use of any other asthma medication for at least 3 months prior to V0.
- Participants who can perform acceptable and repeatable spirometry.
- Participants who can withhold asthma maintenance medication for at least 12 hours prior to V0, 1 and 4 where spirometry and/or Computed Tomography (CT) scan procedures will be performed except for once-a-day dosage where 24 hours will be required.
- Persons capable of becoming pregnant, who have a negative pregnancy test prior to administration of the investigational product (IP) and high-resolution CT scan and must agree to use a highly effective method of birth control (confirmed by the investigator – and consistent with local regulations regarding the methods of contraception for those participating in clinical studies) from randomization throughout the study duration and within 12 weeks after last dose of IP.
