AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
* with the diagnosis of allergic asthma \>1 year duration who, in addition to the standards of the American Thoracic Society (ATS) meet the following criteria:
* with a positive prick skin test (diameter of wheal \> 3 mm) to at least one perennial allergen (e.g. dust mite, animal dander, cockroaches), within the past 5 years or at Visit 1, to which the patient will be exposed on a regular basis (most days) for the duration of the study. A RAST test may be performed for patients with a borderline skin prick test result.
* with total serum IgE level 30 to 700 IU/ml.
* demonstrating 12% increase in FEV1 over baseline value within 30 minutes of taking up to 4 puffs salbutamol (albuterol) or nebulized salbutamol up to 5mg (or equivalent of alternative B-2 agonist) documented within the past year, at screening, during the run-in period or at baseline prior to randomization.
* with FEV1 40-80% of predicted normal value for the patient (demonstrable at least 6 hours after short acting B-2 agonist use or 12 hours after long acting B-2 agonist use) at baseline.
* who have either experienced at least two independent asthma exacerbations requiring unscheduled clinical intervention with a systemic corticosteroid in the past year.
or:
* been admitted to hospital (including intensive care unit) or received emergency room (including urgent care centers) treatment in the past 12 months for an asthma exacerbation, which in accordance with the GINA guidelines met all of the following criteria…
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?

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?
