. Age ≥18 and ≤80 years old, male or female, weight ≥40 kg.
. The subject has been diagnosed with asthma for at least 1 year.
. Pre-bronchodilator FEV1 measured ≤80% of the normal predicted value.
. A positive bronchodilation test within 24 months before informed consent or at screening.
. The subject has received medium-to-high dose ICS combined with at least one control drug, such as LABA, LAMA, LTRA, Oral corticosteroids, theophylline, for at least 3 months before signing the informed consent, and maintained stable treatment regimen and dosage for at least 1 month before signing the informed consent.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Annualized rate of severe asthma exacerbations at Week 52
. Asthma Control Questionnaire-5 (ACQ-6) score ≥1.5.
. Subjects must have experienced at least one severe asthma exacerbation event within 12 months before informed consent, and have not experienced a severe asthma exacerbation event within 30 days before informed consent.
Exclusion criteria
. Chronic obstructive pulmonary disease (COPD) without asthma or other lung disease that may impair lung function, as judged by the investigator.
. Have systemic diseases other than asthma that result in an elevated peripheral blood eosinophil count or other diseases such as helminth parasitic infections for which standard treatment is not received or does not respond.
. Prior autoimmune disease or inflammatory treatment with biologic agents/systemic immunosuppressive agents within 8 weeks or 5 half-lives (whichever is longer) prior to informed consent.
. Previous history of known or suspected immunosuppression, including a history of invasive opportunistic infection, even if the infection has resolved; or the presence of unusual frequent, recurrent, or prolonged infections.
. History of malignancy.
. The presence of any severe and/or uncontrolled medical condition that in the judgment of the investigator may affect the evaluation of the drug, including but not limited to: severe neurological disease, history of severe mental disorder, diabetes mellitus poorly controlled by intensive treatment.
. Active infection or acute infection requiring systemic anti-infective therapy from 4 weeks before enrollment to the time of randomization.
. A history of severe cardiovascular disease or clinically significant abnormalities identified by 12-lead electrocardiogram (ECG) during the screening phase.
