| Study group | Role | What they receive |
|---|---|---|
| Cohort A | approximately 80 healthy participants | |
| Cohort B | approximately 40 mild asthmatics on as-needed low dose inhaled corticosteroids (ICS)-formoterol, or low dose ICS plus as-needed short-acting β2 agonists (SABA), without the need for other controller medication. | |
| Cohort C | approximately 160 moderate to severe asthmatics on low or medium dose ICS-long acting β2 agonists (LABA), high dose ICS alone or in combination with LABA . | |
| Cohort D | approximately 75 asthmatics with protocol defined asthma exacerbation. |

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 18 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 21 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact AstraZeneca Clinical Study Information Center (1-877-240-9479, information.center@astrazeneca.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Descriptive summary of demographic and subject characteristic, clinical characteristics and functional deliverables. (time frame: At baseline). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2026.
