Why People Are Turning to Clinical Trials
Asthma affects people differently depending on where they live. In humid Gulf states like Texas and Florida, mold and pollen trigger symptoms year-round, while the dry winters of Colorado and the Northeast push many patients into flare-ups they never saw coming. Standard treatments help, but a significant share of people with moderate-to-severe asthma still experience poor control on their current inhalers.
That gap is where research steps in. Academic centers such as Duke University, UCSF, the University of Virginia, and Brigham and Women's Hospital in Boston run ongoing asthma studies, and organizations like the American Lung Association coordinate trials across multiple states. The National Institutes of Health's ClinicalTrials.gov registry lists current options, while centers like the UVA Health asthma division actively screen adults with mild allergic asthma for future research.
The common thread is that study teams are looking for real patients, not perfect ones. Most trials need adults 18 and older with a physician diagnosis of asthma who still have symptoms despite using controller medication. Some studies focus on specific groups, like World Trade Center responders with uncontrolled asthma, children ages 2 to 4 with recurrent wheezing, or people with severe asthma already on biologic therapy.
What Participating Actually Looks Like
Joining a trial is rarely a one-visit affair. A typical study involves a screening visit with a consent discussion, allergy skin testing, breathing tests, blood draws, and questionnaires. From there, participants might return for clinic visits spanning months, fill out daily symptom diaries at home, or take an investigational medication alongside their usual treatment.
The level of involvement varies widely. One observational study at Duke tracks people with severe asthma over time, while a University of Virginia screening protocol requires only up to three visits for allergy and lung function testing. Longer trials, like the four-year preschool omalizumab study at Boston Children's Hospital, ask families to come in monthly during treatment and continue with phone check-ins afterward.
Here is a comparison of the types of asthma studies commonly recruiting in the US:
| Study Type | Typical Example | Visit Burden | Compensation Range | Best For |
|---|
| Screening / volunteer database | UVA asthma screening protocol | 1-3 visits | Up to $125 for screening | People unsure if they qualify |
| Phase I safety study | Amgen AMG 691 for mild-moderate asthma | Multiple visits, some up to 8 hours | Up to $4,900 with parking vouchers | Those wanting early access to new drugs |
| Phase IIIb biologic study | ARRIVAL tezepelumab study at BWH | Regular visits over 18 months | Up to $870 for the study period | Severe asthma patients on biologics |
| Observational registry | CHRONICLE study (AstraZeneca) | Ongoing, allows other studies | Compensation provided | Patients wanting minimal disruption |
| Long-term prevention trial | Preschool omalizumab study | Monthly visits for 2 years | Up to $2,560 in gift cards | Families of wheezing young children |
| Multi-center treatment trial | TRIM roflumilast study | 7 clinic visits over 6 months | Compensation varies by center | Adults with poorly controlled asthma and elevated BMI |
Keep in mind that compensation figures vary by study, site, and how much time is required. Some trials offer up to a few thousand dollars over the full duration, while shorter screening studies pay modest amounts for your time and travel. Study-related visits, tests, and medications are generally provided at no cost to participants.
How to Find a Study and Get Started
Start with your own care team. Your allergist or pulmonologist often knows which local research centers are recruiting, and a referral can speed up screening. The American Lung Association's Airways Clinical Research Centers have sites in Arizona, Illinois, North Carolina, New York, and Vermont, each with a dedicated coordinator you can contact directly.
ClinicalTrials.gov remains the most reliable starting point. Search for "asthma" with your state or city, then filter by "Recruiting" status. You will see eligibility criteria up front, including age ranges, smoking history limits, and whether you need to already be on a particular medication. If a study fits, the contact information for the research coordinator is usually listed right on the page.
Before you reach out, have your asthma medication list and recent lung function results handy. Most centers ask about your current inhaler use, how often you need rescue treatment, and your history of hospitalizations or emergency visits. Be honest about smoking history as well, since many trials exclude people with significant pack-year histories to avoid confusing asthma with COPD.
Finally, ask smart questions before signing consent. Confirm what happens if you need to stop early, whether you can stay on your current medications, and who covers treatment for any complications. Every US trial requires informed consent, and you can withdraw at any time without losing your regular care.
A Practical First Step
Start small. Consider a screening or volunteer database study first, especially if you are new to research or unsure whether you meet eligibility. These require fewer visits, carry lower commitment, and let you learn how a research clinic operates. If the fit feels right, you can move on to longer interventional trials with investigational biologics or new inhaled medications.
Asthma research has come a long way, and trials now explore everything from biologic treatments like tezepelumab and dupilumab to mucus-targeting therapies and better rescue inhaler strategies. By participating, you gain close monitoring and access to treatments not yet on the market, while helping researchers understand a condition that affects millions. Talk to your doctor, check ClinicalTrials.gov, and reach out to a local research center to see what is open near you.
