Why Asthma Research Matters Right Now
Asthma affects millions of people across the United States, yet many still struggle with symptoms despite using maintenance inhalers and avoiding triggers. The reality is that standard treatments do not work equally well for everyone. Some people have eosinophilic asthma that resists conventional therapy. Others experience frequent exacerbations that land them in urgent care. These gaps in treatment are exactly what drive the research forward.
The American Lung Association runs the Airways Clinical Research Centers (ACRC) network, the largest nonprofit clinical research network in the country dedicated to asthma and COPD. With over 30 trial sites spread across states like Arizona, Illinois, New York, North Carolina, and Vermont, the network has been running patient-centered studies for more than two decades. What makes this network unusual is that it is not funded by a single pharmaceutical company. Instead, it brings together academic centers, hospital systems, and independent investigators to answer questions that matter to patients—not just shareholders.
Meanwhile, pharmaceutical companies and university hospitals are conducting trials on biologics, new inhaler formulations, and even oral medications that target the underlying inflammation rather than just relaxing the airways. The scope of asthma research happening in the United States right now is wider than many people realize.
What Kinds of Asthma Trials Are Available
Not all asthma trials are the same. Some evaluate whether a drug that is already on the market for one condition might work for asthma. Others test entirely new molecules that have never been prescribed before. Understanding the landscape helps you decide where you might fit in.
Biologic trials are among the most active areas right now. Drugs like benralizumab and dupilumab have already changed the game for severe eosinophilic asthma, and researchers are now testing new biologics that target different inflammatory pathways. These trials often look for people whose asthma remains uncontrolled despite using high-dose inhaled corticosteroids and long-acting beta-agonists.
Inhaler and device studies tend to focus on delivery mechanisms or combination therapies. You might test a new dry powder inhaler or a reformulated version of an existing medication. These trials are often shorter and less intensive than biologic studies.
Lifestyle and prevention trials look at non-drug interventions. The American Lung Association is currently running a Lung Health Cohort Study that follows young, healthy adults to understand lung function over time. Another study is evaluating whether house dust mite allergen tablets can prevent asthma from developing in children.
Acute exacerbation studies focus on people who are already having flare-ups. One recent trial, for example, evaluated rademikibart as an add-on therapy during an active asthma attack.
The table below compares the main types of asthma clinical trials so you can see at a glance what might match your situation.
| Trial Type | Typical Duration | Who It May Suit | What to Expect | Potential Drawbacks |
|---|
| Biologic trials | 6–24 months | Severe or eosinophilic asthma patients | Injections or infusions, frequent lab work | Time commitment, possible injection-site reactions |
| Inhaler studies | 3–12 months | Mild to moderate asthma | Daily inhaler use, symptom diaries | May need to pause current medications |
| Lifestyle/prevention | 1–5 years | Mild asthma or at-risk individuals | Behavioral changes, fewer clinic visits | Slow results, less direct benefit |
| Acute exacerbation trials | 4–8 weeks | People with frequent flare-ups | Short-term, intensive monitoring | Must enroll during or right after an attack |
How the Screening and Enrollment Process Works
Walking into a clinical trial for the first time can feel overwhelming, but the process follows a predictable rhythm. The first step is usually a phone or online screening questionnaire. A research coordinator will ask about your diagnosis, your current medications, how often you use a rescue inhaler, and whether you have been hospitalized for asthma recently. They are not trying to disqualify you—they are matching you to the right protocol.
If you pass the initial screen, you will be invited to an in-person screening visit. This tends to be thorough. Expect a physical exam, blood work, breathing tests like spirometry, and sometimes an electrocardiogram or chest X-ray. The site will also go over the informed consent document with you in detail. This is not just a formality. The consent form explains what the study drug is, what the known risks are, what happens if you are placed in the placebo group, and your right to withdraw at any time.
One thing that surprises many people is how long the screening phase can take. It is not unusual for a few weeks to pass between the first phone call and the actual first dose of the study drug. Researchers need to confirm that you meet every inclusion criterion and that none of the exclusion criteria apply. Patience is part of the process.
After enrollment, the schedule varies. Some trials require overnight stays at a research facility. Others involve weekly check-ins for the first month and then taper to monthly visits. You may be asked to keep a symptom diary, use a peak flow meter at home, or download an app that tracks your medication use. None of this is meant to be burdensome, but it does require a level of commitment that goes beyond a typical doctor visit.
What About Compensation and Costs
One of the most common questions is whether participants get paid. The short answer is that most asthma clinical trials offer compensation for time and travel, but the structure varies. Some studies pay a flat amount per completed visit. Others break it down by procedure: a screening visit might bring a set amount, a bronchoscopy visit a higher sum, and follow-up blood draws a smaller figure. Based on publicly available listings, compensation for asthma studies can range from a few hundred dollars for shorter trials to more substantial amounts for studies requiring overnight stays or invasive procedures.
The study-related medical care itself is almost always provided at no charge. That includes physical exams, lab tests, imaging, and the investigational medication. You do not need health insurance to participate, and the research site will not bill your insurance carrier for study procedures. However, if you need to see your regular doctor for something unrelated to the trial, that remains your responsibility.
It is worth understanding the distinction between reimbursement and compensation. Regulatory guidelines in the United States draw a line between the two. Reimbursement covers your actual expenses—parking, mileage, child care—while compensation acknowledges the time and inconvenience of participation. Both are reviewed by an ethics board to ensure that the amounts are reasonable and do not pressure anyone into joining a trial purely for the money.
Real Experiences from People Who Have Enrolled
Stories from past participants can help demystify the experience. One participant at a research center in the Southwest described how she had been using three different medications to control her asthma and still woke up wheezing several nights a week. She enrolled in a biologic trial and, within a few months, noticed that she was reaching for her rescue inhaler far less often. "The team treated me with so much care," she said. "I felt heard, respected, and informed every step of the way."
Another participant from the Midwest joined an inhaler study after reading about it on ClinicalTrials.gov. He was initially nervous about the possibility of receiving a placebo, but the research coordinator walked him through the study design and explained that all participants would receive standard-of-care treatment as a baseline. He ended up learning more about his own lung function through the trial's pulmonary tests than he had in years of routine checkups.
These experiences are not universal, and not every trial produces dramatic results. Some participants find that the study drug does not improve their symptoms. Others deal with side effects like fatigue, headache, or injection-site reactions that resolve on their own. The key is asking questions before you commit and staying in close communication with the research team throughout.
How to Find Asthma Clinical Trials Near You
The most comprehensive resource is ClinicalTrials.gov, a database maintained by the National Library of Medicine. You can search by condition, location, and trial phase. The filters let you narrow the results to studies that are actively recruiting, which saves time. Typing in "asthma clinical trials enrolling near me" or "asthma research studies [your city]" can surface local options, though the database itself is the most reliable starting point.
The American Lung Association's ACRC network is another excellent resource. Their website lists recruiting trials across the country, and you can contact the center nearest to you directly. The ACRC has sites in Tucson, Chicago, New York, Durham, and Burlington, among other locations. Each site has a dedicated research coordinator who can walk you through what is available.
University hospitals and academic medical centers are also worth checking. Institutions like Baylor College of Medicine, Columbia University, Northwestern University, and the University of Arizona frequently run asthma trials. Their websites often have a "clinical trials" or "research studies" section that lists current enrollment opportunities.
Beyond the databases, a conversation with your pulmonologist or allergist can open doors. Many physicians have relationships with research networks and can refer you to a trial that fits your clinical profile. They can also help you weigh the risks and benefits based on your specific medical history.
Questions to Ask Before You Enroll
Before signing a consent form, there are several questions worth asking the research team. What is the trial phase, and what is already known about the drug's safety? How often will I need to come to the clinic, and how long does each visit last? What happens if I experience a side effect—who do I call, and what kind of medical support is available after hours? If the drug works for me, is there a way to continue receiving it after the trial ends? What are my options if I want to withdraw?
These questions are not confrontational. They are practical. A good research team will welcome them and give clear answers.
For people whose asthma has been stubborn or unpredictable, clinical trials represent more than a shot at a new drug. They offer a structured way to learn about your own health while contributing to research that could shape how asthma is treated in the years ahead. The decision to enroll is personal, and it deserves the same careful thought you would give to any major medical choice.
