The Current Landscape of Asthma Research in America
Asthma research in the US has shifted dramatically in recent years. Instead of one-size-fits-all inhalers, scientists now focus on targeted biologic therapies that address specific types of airway inflammation. One standout example is depemokimab, approved by the US Food and Drug Administration for severe eosinophilic asthma, with trial data showing a roughly 54% reduction in severe asthma exacerbations. Another major development is Breztri Aerosphere, a single-inhaler triple therapy approved for asthma in patients ages 12 and older, based on the Phase III KALOS and LOGOS trials.
Beyond these breakthroughs, the American Lung Association runs the Airways Clinical Research Centers, a network of sites across the country actively enrolling participants. Studies like the COPD-OMA trial test whether the asthma medication omalizumab can reduce flare-ups in people with allergic COPD. The TRIM trial, meanwhile, examines roflumilast for adults with poorly controlled asthma and elevated BMI, with recruiting centers in Arizona, Illinois, New York, and Vermont.
What this means for you is simple: there is more choice than ever, but also more complexity. Not every study suits every patient, and understanding the differences is the first step toward a good match.
What Typical Participants Look Like
Let's paint a picture of the people these trials are designed for.
Meet Marcus, a 34-year-old teacher from Chicago. He has had allergic asthma since childhood, uses a daily controller inhaler, but still ends up in urgent care once or twice a year during allergy season. His main concern is time, because he cannot afford to miss school days.
Then there is Dana, a 58-year-old retiree in Tucson with poorly controlled asthma and a higher BMI. She has tried multiple combination inhalers without full relief and wonders if a different class of medication might work better for her body.
Finally, consider the parents of 8-year-old Liam in New York, whose pediatric asthma is difficult to control despite daily medication. They want options that are safe for children but feel overwhelmed by medical jargon.
Each of these profiles maps to a different type of study, which is exactly why the eligibility criteria matter so much.
How to Find a Study That Matches You
Start with the official registry. ClinicalTrials.gov lists every study registered in the US, complete with eligibility criteria, locations, and contact information. You can filter by condition, age range, and distance from your zip code. Many people search terms like "asthma clinical trials near me" or "severe asthma study [state]" and find local options within a few minutes.
Next, check disease-specific organizations. The American Lung Association maintains a searchable database of current trials and provides plain-language summaries of what each study involves. Their Airways Clinical Research Centers are particularly active in asthma and COPD research, with coordinators who can walk you through the process by phone.
Private research centers also run their own recruitment. Many allergy and asthma clinics across the country maintain participant databases and notify you when a relevant study opens. A quick call to a local research coordinator can place you on a list for future trials, even if nothing fits you right now.
A Closer Look at What Different Trials Offer
| Study Type | Example | Typical Eligibility | Time Commitment | Participant Support | Key Considerations |
|---|
| Biologic therapy | Depemokimab trials | Severe eosinophilic asthma, frequent exacerbations | 12-24 months | Study medication, medical monitoring, compensation for time and travel | Requires regular injections at clinic visits |
| Triple therapy inhaler | Breztri (KALOS/LOGOS) | Persistent asthma, ages 12+ | 6-12 months | Study medication and monitoring | Single daily inhaler, fewer devices to manage |
| Medication repurposing | COPD-OMA (omalizumab) | COPD with allergies, flare-up history | 14-16 months | Monitoring plus a follow-up phone call | Tests an existing allergy drug for a new use |
| Alternative mechanism | TRIM (roflumilast) | Poorly controlled asthma, elevated BMI, adults 18+ | Varies by site | Daily diary, clinic visits, compensation | Not a steroid-based approach; targets inflammation differently |
What to Expect Before You Enroll
Every legitimate trial follows a clear process. You start with a screening visit where a coordinator reviews your medical history and performs a few tests, often including lung function measurements like spirometry. If you qualify, you receive detailed informed consent documents explaining the risks, benefits, and your right to withdraw at any time.
Compensation varies by study but commonly covers time and travel for in-person visits. One trial coordinator noted that qualified participants in device studies receive compensation for the time involved, and the COPD-OMA study explicitly offers compensation for time and travel. You should ask about this during screening so there are no surprises later.
The reality is that most asthma trials provide the investigational medication free of charge, along with regular check-ups from specialists who track your lung health closely. For many participants, that level of monitoring is itself a benefit, especially if they have struggled to see a pulmonologist regularly.
Questions to Ask Before You Say Yes
Before committing, ask the coordinator these questions. How long is the study, and how many visits are required? Will the investigational medication be provided, and what happens if I respond well at the end? Will I need to stop any of my current medications, and if so, for how long? What safety monitoring is in place, and who covers any costs related to adverse events? Is there compensation, and what exactly does it cover?
Also ask whether you will learn which treatment you received. Some trials are blinded, meaning neither you nor the study team knows whether you received the experimental drug or a placebo. Others are open-label, where everyone gets the active treatment. Knowing this in advance helps you set realistic expectations.
Practical Next Steps for Your Search
Start by creating a short list of studies that match your age, asthma severity, and location. Use the ClinicalTrials.gov search filters to narrow results, then cross-check the American Lung Association's listings. Contact the research coordinator by phone rather than email if you can, since coordinators often respond faster to direct calls and can answer eligibility questions on the spot.
Keep a record of your current medications, including doses and how long you have taken them. Many trials require you to be stable on a daily controller therapy for several months before enrolling, so having this information ready speeds up the screening call. If a study does not fit you today, ask to join the center's database for future trials, as many centers welcome applications for later opportunities.
Asthma research in the United States is moving faster than ever, and the treatments being tested today could become the standard of care tomorrow. Whether you are exploring a biologic for severe symptoms or a triple therapy that simplifies your daily routine, a clinical trial can offer access to care you might not otherwise find. Take the first step by searching your area, making one phone call, and asking the questions that matter to you. The next breakthrough in asthma care could start with your participation.
