1. A severe asthma exacerbation within 8 weeks of Screening (Visit 1) or within 12 weeks of randomisation (Visit 3).
2. A positive test result of an approved antigen test (confirmed by a positive RT-PCR) or a positive RT-PCR test for SARS-CoV-2, the virus responsible for COVID-19.
3. Participants with a significant COVID-19 illness within 6 months of enrolment:
- Participants with a diagnosis of COVID-19 pneumonia based on radiological assessment.
- Participants with a diagnosis of COVID-19 requiring hospitalisation and/or oxygen supplementation therapy.
4. Clinically important pulmonary disease other than asthma eg, active lung infection, COPD, bronchiectasis, pulmonary fibrosis, cystic fibrosis, hypoventilation syndrome associated with obesity, lung cancer, history or planned lung lobectomy, alpha-1 anti-trypsin deficiency, primary ciliary dyskinesia, Churg-Strauss syndrome, allergic bronchopulmonary aspergillosis and hyper-eosinophilic syndrome.
5. 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 investigator and could:
- Affect the safety of the participant throughout the study.
- Influence the findings of the study or the interpretation.
- Impede the participant's ability to complete the entire duration of study.
6. Any clinically significant cardiac disease:
- Acute coronary syndrome (acute myocardial infarction, unstable angina) or coronary intervention with percutaneous coronary intervention/coronary artery bypass surgery within 6 months.
- Heart failure NYHA II-IV.
- Untreated high degree atrioventricular-block (= 3:1 conduction rate/Grade III block)/ significant sinus node dysfunction/pause or therapy requiring tachyarrhythmia.

10. Participants with a recent history of, or who have a positive test for, infective hepatitis or unexplained jaundice, or participants who have been treated for hepatitis B, hepatitis C, or HIV. For the hepatitis B testing (HBsAg, anti-HBs, and anti-HBc), any of the following would exclude the participant from the study:
- Participants positive for HBsAg.
- Participants positive for anti-HBc.
11. Evidence of active or untreated latent TB:
- Positive IGRA, or repeated indeterminate IGRAs, untreated LTBI (unable to be treated for, or declines treatment of LTBI).
- Participants newly diagnosed with LTBI at Visit 1 could be considered for rescreening if they complete a full course of treatment for LTBI in accordance with recommended treatment guidelines prior to rescreening. In this situation, repeat IGRA test is not required after completion of treatment for LTBI.
- Participants with an indeterminate IGRA should undergo a repeat test and if still indeterminate may be enrolled only after being treated for LTBI.
