Why Asthma Research Matters Right Now
More than 25 million people in the United States live with asthma, according to CDC surveillance data. That number has held steady for years, but what has changed is the pace of innovation. Researchers are testing therapies that go far beyond the standard inhaler. Biologic medications, which target specific inflammatory pathways rather than broadly suppressing the immune system, have reshaped the conversation around moderate to severe asthma. The FDA approved depemokimab (EXDENSUR) in late 2025, a biologic given every six months for severe eosinophilic asthma, and several other candidates remain in active trials across the country.
The reality is that not every treatment works for every person. Asthma comes in different subtypes: allergic, eosinophilic, exercise-induced, and others that do not fit neatly into a single category. Clinical trials are the mechanism that moves the field forward, matching specific therapies to specific patients. Without enough volunteers, promising drugs stall in development, sometimes for years.
What Kinds of Trials Are Available
Asthma trials span a wide range. Some test new medications, others examine devices like smart inhalers, and a smaller number explore behavioral interventions or environmental modifications. The phase of a trial tells you how far along the research is.
Phase 1 trials are small and focused on safety. They typically enroll healthy volunteers or a limited number of patients with the condition. Phase 2 trials expand the group and start testing how well a treatment works at different doses. Phase 3 trials are the large, often multi-site studies that compare a new drug against a placebo or standard treatment. If the data holds up, the drug moves toward regulatory review. Phase 4 trials happen after approval, monitoring long-term safety and effectiveness in the real world.
A recent example is the GB-0895 trial, a Phase 3 study evaluating an injectable therapy for severe uncontrolled asthma. Participants received either the investigational drug or placebo every six months, with researchers tracking exacerbation rates over 52 weeks. The trial involved sites across multiple countries, including the United States, reflecting how global asthma research has become.
Another active study, the TRIM trial (Trial of Roflumilast in Asthma Management), targets adults with poorly controlled asthma and elevated BMI. It operates through the American Lung Association's Airways Clinical Research Centers in Arizona, Illinois, New York, North Carolina, and Vermont. That geographic spread matters because it means patients in different regions can access research without relocating to a major coastal medical hub.
How Much Do Trials Pay
Compensation varies widely depending on the study's length, the number of visits, and the procedures involved. Short screening visits or focus groups may offer modest amounts, while long-term trials with frequent onsite visits can provide more substantial payments.
| Trial Type | Example Site | Compensation Range | Time Commitment | What's Involved |
|---|
| Screening-only | UVA Health Asthma Studies | Up to $125 | 1-3 visits | Allergy tests, breathing tests, blood samples |
| Moderate-length trial | Clinical Research of West Florida | Up to $1,100 | Several months | Multiple visits, investigational medication use |
| Extended trial | University of Wisconsin | Up to $1,350 | Varies | Regular check-ins, health assessments |
| Long-term trial | Brigham and Women's Hospital | Up to $3,900 | 26 visits over 22 months | Comprehensive monitoring, diary completion |
| Focus groups/surveys | Various research firms | $100–$350 | Single or few sessions | Opinion sharing, product feedback |
It is worth noting that compensation reflects the time and inconvenience of participation, not the potential benefit of the treatment. The study drug, related tests, and monitoring are typically provided at no cost to the participant. Insurance is generally not billed for trial-related care. Some sites also cover transportation or parking, though that varies by location and budget.
What Actually Happens During a Trial
The process tends to follow a predictable rhythm. After you express interest, a research coordinator conducts a pre-screening call or sends a form asking about your asthma history, current medications, allergies, and general health. If you match the basic criteria, you are invited for an in-person screening visit.
That visit almost always includes informed consent. A staff member walks you through the study's purpose, what will happen at each visit, potential risks, and your right to withdraw at any time. You sign the consent form before anything else moves forward. Then come the baseline assessments: lung function tests, blood draws, allergy skin testing, and sometimes a physical exam. For women of childbearing age, a urine pregnancy test is standard.
If you qualify, you are randomized. In blinded trials, neither you nor the research team knows whether you receive the active drug or placebo. This design eliminates bias, but it also means you might not get the experimental treatment. Some trials offer an open-label extension after the blinded phase ends, giving all participants access to the active drug.
During the treatment period, you attend scheduled visits for monitoring. You may be asked to keep a daily asthma diary, tracking symptoms, peak flow readings, and rescue inhaler use. The research team checks for adverse events at every visit. Safety protocols are strict, and ethics boards review the study regularly to protect participants.
Finding a Trial That Fits
ClinicalTrials.gov remains the most comprehensive registry. Run by the National Library of Medicine, it lists thousands of asthma studies with filters for location, phase, and recruitment status. Searching "asthma" and filtering by "recruiting" in your state is a solid starting point. The American Lung Association also maintains a searchable database of trials through its Airways Clinical Research Centers network.
Academic medical centers in major cities tend to have the most active research programs. Boston, New York, Chicago, Houston, and Los Angeles are hubs, but smaller cities like Tucson, Gainesville, and Madison also host significant asthma research. Do not assume you need to live near a teaching hospital. Some trials use remote monitoring or partner with local clinics to reduce travel burden.
Before committing, ask the study coordinator a few practical questions. How many visits are required, and how long does each last? What happens if your asthma worsens during the trial? Are there restrictions on other medications? Can you continue seeing your regular doctor? The answers should feel clear and reassuring. If a coordinator seems evasive or rushed, that is a red flag.
Who Can Participate
Eligibility criteria vary by study, but most trials look for specific patient profiles. Age requirements often range from 12 or 18 years up to 65 or 75. Some trials focus on mild allergic asthma, others on severe uncontrolled disease. Commonly, participants must have a confirmed diagnosis for at least one year, be on stable background therapy, and demonstrate a certain level of lung function impairment. Smoking history, BMI, and the presence of other lung conditions like COPD can all affect eligibility.
Exclusion criteria are just as important. Active respiratory infections, recent oral steroid use for an exacerbation, significant cardiac disease, or a history of certain cancers may disqualify you. These restrictions exist to protect participants and ensure clean data. The screening process is designed to catch these issues before enrollment.
Risks and Realities
No clinical trial is risk-free. Experimental drugs can cause unexpected side effects. Some are mild, like injection site reactions or headaches. Others may be more serious, and the full picture only emerges over time. The trial team monitors participants closely, but you remain the most important reporter. If something feels off, speaking up is not complaining. It is the point.
There is also the possibility that the treatment does not work for you, or that you are assigned to the placebo group and see no improvement. Some participants find that their asthma stays the same or worsens temporarily. The informed consent document should spell out all known risks, and you should read it carefully before signing.
On the other hand, participants gain access to cutting-edge therapies years before they reach the market. They receive medical attention from specialists who understand asthma deeply. Many report a sense of purpose from contributing to research that could help others breathe easier. Sarah, a 42-year-old teacher in Ohio who participated in a biologic trial through a university hospital, described the experience as "the most closely monitored my asthma has ever been." She added that the monthly check-ins gave her a level of insight into her own triggers that she had never had before, even if the trial drug itself was not a miracle cure.
Regional Resources Worth Knowing
The American Lung Association's Airways Clinical Research Centers operate in multiple states, offering free or low-cost access to trials. Duke University in North Carolina, the University of Arizona in Tucson, Northwestern University in Chicago, Mount Sinai in New York, and the University of Vermont all run active asthma research programs. Some centers have dedicated asthma research hotlines. Others list recruiting studies directly on their websites.
Local allergy and immunology practices sometimes partner with larger trial networks. If you already see a pulmonologist or allergist, ask whether they know of recruiting studies. Word of mouth within the medical community often surfaces opportunities before they appear on public registries.
For those in rural areas, telemedicine components are becoming more common in asthma trials. Some studies now allow remote consent, at-home spirometry monitoring, and virtual check-ins between in-person visits. This trend has expanded access to people who previously could not participate due to distance.
Taking the Next Step
The decision to join a clinical trial is personal and should involve a conversation with your family and your regular doctor. Nobody should pressure you into it. But if your current asthma management feels stagnant, or if you are curious about what is coming next in respiratory medicine, exploring clinical trials is a reasonable move.
Start by searching ClinicalTrials.gov with your city or zip code. Narrow the results to "recruiting" studies and read the eligibility criteria. If something looks like a fit, call or email the contact listed. The screening team will walk you through the rest. You can always say no at any point, and walking away after gathering information is a perfectly acceptable outcome.
The asthma treatments of tomorrow depend on the volunteers of today. Whether you participate or not, knowing what is available keeps you informed and engaged in your own care. And that, regardless of trial outcomes, is never a wasted effort.
