Why Asthma Research Is Having a Moment
Asthma affects roughly 25 million people in the United States, and for a significant portion of them, standard treatments simply don't deliver the control they need. You might use a daily controller inhaler, keep a rescue inhaler within reach, and still find yourself in the emergency room once or twice a year. That's the reality for many people with moderate to severe asthma, and it's exactly why research centers across the country are working hard on new approaches.
The landscape of asthma treatment has shifted dramatically. Where doctors once relied almost exclusively on inhaled corticosteroids and bronchodilators, researchers now investigate biologic therapies that target specific inflammatory pathways. The PASSAGE study, a phase 4 real-world trial presented at the 2026 ATS International Conference in Orlando, examined tezepelumab across diverse patient populations — including Black and African American patients, adolescents, smokers, and people with overlapping asthma and COPD. These are groups that have historically been left out of clinical research, and the results showed meaningful reductions in exacerbation rates across all of them. The takeaway? The research community is finally paying attention to the fact that asthma doesn't look the same in everyone, and treatments shouldn't either.
Meanwhile, pharmaceutical companies are racing to develop new oral medications. Eli Lilly's brenipatide, currently in phase 2 trials, represents a different approach from the injectable biologics that have dominated recent asthma research. If you're someone who dreads injections, you'll understand why an effective oral option would matter. The pipeline is active, and that means more opportunities for patients to get involved in asthma clinical trial enrollment at centers near them.
What Kinds of Trials Are Out There
Clinical trials come in several phases, each with a different goal. Phase 1 trials focus on safety and dosage, usually involving a small group. Phase 2 expands to a larger group and starts looking at how well the treatment works. Phase 3 trials involve hundreds or thousands of participants across multiple locations and compare the new treatment against existing standard therapies. Phase 4 studies happen after a treatment is already on the market, gathering real-world data on long-term safety across broader populations.
The types of interventions being tested vary widely. Some trials evaluate biologic injections — medications like dupilumab, omalizumab, and tezepelumab that target specific immune pathways. Others test novel inhaler formulations, oral medications, or even combination approaches. If you're looking specifically for biologic asthma clinical trials, you'll find the most options in phase 3 and phase 4 studies, where researchers are comparing these targeted therapies head-to-head or testing them in populations that were excluded from earlier research.
Here is a comparison of common asthma trial categories to help you understand the landscape:
| Trial Type | Typical Duration | Participant Commitment | Compensation Range | Best For |
|---|
| Phase 1 (Safety/Dosing) | Weeks to a few months | Intensive monitoring, possibly overnight stays | Often higher due to time burden | Those comfortable with higher uncertainty |
| Phase 2 (Efficacy Signals) | Several months | Regular clinic visits, lab work | Moderate | People with specific asthma subtypes |
| Phase 3 (Confirmation) | 6 months to 2 years | Periodic visits, diary entries | Varies by visit frequency | Those wanting to try a near-market treatment |
| Phase 4 / Observational | 1 to 4 years | Less frequent visits, surveys | Lower per visit but accumulates | Those already on a treatment being studied |
| Pediatric Trials | Varies | Parent involvement, school coordination | Often includes travel reimbursement | Families of children with asthma |
Compensation structures differ from one study to the next. Some trials pay a flat amount per completed visit, while others offer reimbursement for travel and parking along with a stipend for time. Industry reports suggest that longer, more intensive trials can compensate participants in the range of a few thousand dollars over the full study period, but shorter survey-based studies may offer gift cards in a more modest range. The Brigham and Women's Hospital Asthma Research Center in Boston, for example, has recruited for studies that compensate participants for time and travel across multiple visits over nearly two years. The key is to ask the research coordinator upfront about the full asthma clinical trial compensation schedule before you commit — don't be shy about this conversation.
What Actually Happens When You Join
The process starts with a screening visit. You'll sit down with a research coordinator who explains the study in detail, and you'll sign an informed consent document. This isn't just paperwork — it's the document that outlines every procedure, every risk, and every right you have as a participant, including the right to walk away at any time without penalty.
After consent, you'll undergo screening assessments. These typically include a review of your medical history, a physical exam, blood work, and lung function tests like spirometry. If you meet the asthma clinical trial eligibility criteria — which vary by study but often include a confirmed asthma diagnosis, a certain number of exacerbations in the past year, and current use of controller medications — you'll be randomized into a treatment group.
Randomization is a concept that makes some people nervous, and it's worth addressing directly. In many trials, participants are randomly assigned to receive either the investigational treatment, a placebo, or the standard of care. You won't know which group you're in, and often neither will the research team. This double-blinding is the gold standard for producing reliable data. If the possibility of receiving a placebo concerns you, discuss it with the research team. Some trials have an open-label extension phase where all participants eventually receive the active treatment — ask whether this applies to the study you're considering.
During the study, you'll attend regular clinic visits. Depending on the trial, these might happen weekly, monthly, or every few months. You'll likely keep a symptom diary, track your peak flow readings at home, and report any changes in your health. The research team monitors you closely — in many ways, more closely than you'd be monitored in routine clinical care. One participant at Epic Medical Research described it this way: "The team treated me with so much care. I felt heard, respected, and informed every step of the way."
A point worth emphasizing: participation in a clinical trial should not cost you money for the investigational treatment itself. Study-related medications, procedures, and tests are typically covered by the sponsor. Your routine asthma medications, however, may still go through your insurance. Clarify this distinction during the screening process so there are no surprises.
Finding a Trial That Fits
The most comprehensive starting point is ClinicalTrials.gov, a database maintained by the U.S. National Library of Medicine. You can search by condition, location, and study phase. If you're looking for asthma clinical trials near me, typing "asthma" and your city or state will pull up actively recruiting studies in your area. The site updates frequently, so checking back every few weeks is a good habit.
The American Lung Association maintains a network of Airways Clinical Research Centers at institutions like the University of Arizona in Tucson, Brigham and Women's Hospital in Boston, and others spread across the country. These centers have dedicated staff who can walk you through available studies. The Asthma and Allergy Clinical Research Center at Boston Children's Hospital, led by Dr. Wanda Phipatanakul, runs multiple pediatric asthma clinical trials for families whose children struggle with wheezing and allergic asthma. For adults, university-based programs at the University of Michigan and Harvard Medical School regularly recruit participants for everything from mild asthma interventions to severe asthma biologic studies.
When you find a trial that interests you, here are the questions worth asking the research coordinator:
What is the purpose of this study and what phase is it in? What are the known risks and side effects of the investigational treatment? How many visits are required, and how long does each visit last? Will I be reimbursed for travel or parking? What happens if my asthma worsens during the trial? Can I continue seeing my regular pulmonologist? What happens after the study ends — will I have access to the treatment?
Another participant from Epic Medical Research summed up the experience: "The whole process was easier than I expected. Free check-ups, real conversations, and compensation that respected my time." That sentiment captures something important — participating in a trial is a two-way relationship. You're not just a subject. You're contributing to knowledge that could change how asthma is treated for millions of people.
That said, it's not for everyone. The time commitment is real, the possibility of side effects exists, and the uncertainty of not knowing whether you're receiving the active treatment can be psychologically challenging. A respiratory therapist in Tucson who works with trial participants put it this way: the people who have the best experience are those who go in with clear expectations, ask every question on their mind, and view the trial as a partnership rather than a last resort. If you're considering an asthma clinical trial, start by having an honest conversation with your current pulmonologist or primary care provider. They can help you weigh the risks and benefits in the context of your specific medical history. Then visit ClinicalTrials.gov or the American Lung Association's website to explore what's recruiting in your area. The trial that could change your asthma management — and contribute to the next generation of treatments — might be closer than you think.
