• Male participants who are sexually active must agree to use a double barrier method of contraception (condom with spermicide) from the first dose of the study drug until 8 weeks after last dose
• Participant has documented treatment with a stable dose of low to medium dose inhaled corticosteroids (defined as >250 and ≤500 mcg fluticasone proprionate/day or equivalent or, >400 to ≤800 mcg Budesonide/day for at least 6 months prior to enrolment
• long-acting β2-agonist (LABA) for at least 6 months prior to enrolment
• Participant has blood eosinophils ≥ 200 cells/μl or FENO ≥25ppb at Visit 1 for all participants except for those with previous biologic therapy without washout who will be required to washout prior to screening.
• Participant has ACQ-6 ≥ 1.5 at visit 1
• Participant has a history of poorly controlled asthma (i.e. ≥ 2 exacerbations in past 24 months)

Exclusion Criteria:

• Participant is, in the opinion of the investigator, mentally or legally incapacitated, preventing informed consent from being obtained, or cannot read or understand written material
• Participant has clinically important pulmonary disease other than asthma (e.g. active lung infection, chronic obstructive pulmonary disease, bronchiectasis, pulmonary fibrosis, cystic fibrosis, hypoventilation syndrome associated with obesity, lung cancer, alpha-1 antitrypsin deficiency and primary ciliary dyskinesia) or been diagnosed with pulmonary or systemic disease other than asthma that is associated with elevated peripheral eosinophil counts (e.g. allergic bronchopulmonary aspergillosis/mycosis, Churg-Strauss syndrome, hypereosinophilic syndrome), except for those atopic conditions that can be associated with asthma (e.g. allergic rhinitis, sinusitis with or without polyposis, eczema, and eosinophilic esophagitis)
• Any disorder, including, but not limited to, cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, haematological, psychiatric, or major physical impairment that is not stable in the opinion of the Qualified Investigator and/or could affect the safety of the participant throughout the study, influence the findings of the study or their interpretations, or impede the participant's ability to complete the entire duration of the study, as assessed by the Qualified Investigator.
• Known history of allergy or reaction to the study drug formulation
• Acute upper or lower respiratory infections requiring antibiotics or antiviral medication within 30 days prior to the date of informed consent
• Clinically significant asthma exacerbation, defined as a change from baseline deemed clinically relevant in the opinion of the Qualified investigator, including those requiring the use of OCS, or an increase in maintenance dosage of OCS within 30 days prior to the date of informed consent. Participants with an exacerbation after providing informed consent but prior to treatment start will be excluded from the study
• Receipt of immunoglobulin or blood products within 30 days prior to the date of informed consent
• Receipt of live attenuated vaccines 30 days prior to the date of enrolment

• Planned surgical procedure during the conduct of the study
• Concurrent enrolment in another clinical trial
• Participant has history of alcohol or drug abuse within 12 months prior to the date of informed consent
• Participant is a female who is ≤8 weeks post-partum or breast feeding an infant
• Participant is pregnant, or intends to become pregnant during the time course of the study
• Participant is unable to perform MRI breath-hold maneuver
• Participant is unable to perform spirometry maneuver
• Participant is hospitalized or has had a major surgical procedure, major trauma requiring medical attention, or significant illness requiring medical attention within 4 weeks of Visit 1
• Participant has a blood pressure of >150 mmHg systolic or >95 mmHg diastolic on more than 2 measurements done >5 minutes apart at Visit 1
• In the opinion of the investigator, participant suffers from any physical, psychological or other condition(s) that might prevent performance of the MRI, such as severe claustrophobia
• Participant has implanted mechanically, electrically or magnetically activated device or any metal in their body, which cannot be removed, including but not limited to pacemakers, neurostimulators, biostimulators, implanted insulin pumps, aneurysm clips, bioprosthesis, artificial limb, metallic fragment or foreign body, shunt, surgical staples (including clips or metallic sutures and/or ear implants) - at the discretion of the MRI Technologist.
