Asthma clinical trials in Colorado: what to expect
Most recruiting asthma trials are for moderate-to-severe asthma that stays uncontrolled on an inhaled steroid. They test biologic injections aimed at the type of inflammation driving your asthma, new inhaler combinations, and longer-acting versions of existing drugs. Others study asthma in children, exercise and self-management programs, and ways to reduce flare-ups that lead to urgent care visits.
In Colorado, recruiting asthma studies are concentrated in Aurora, Colorado Springs, Denver and Lakewood. 13 of the 22 are run by a drug or device company, which usually means a larger study with travel reimbursement; the rest are academic or hospital-led.
Who asthma trials usually look for
Trials ask for a confirmed diagnosis, a daily maintenance inhaler at a stated dose, and usually one or two flare-ups in the past year that needed oral steroids. Breathing tests at screening must fall in a range, and biologic trials pick participants by a blood eosinophil count or allergy markers measured at the site. Most adult trials exclude current smokers and people with COPD or another lung disease. Separate studies enroll children aged 6 to 11 and teenagers.
What taking part involves
Screening includes spirometry and blood work, then a run-in of a few weeks while you record symptoms and inhaler use in a diary or app. Biologic trials give an injection every two to eight weeks for six to twelve months, with breathing tests at each visit; many are placebo controlled, with your regular inhalers continued throughout and rescue inhaler always allowed. Flare-ups during the study are treated as usual. Study treatment and tests are free and visits are usually paid.
Questions worth asking the study team
Whether your current inhalers stay the same or are switched to a study inhaler; how often breathing tests are needed; the chance of placebo and whether an extension follows; and what to do during a flare-up while enrolled.

This trial is looking for people with asthma who want to try different treatments to help with their condition. Participants will compare using inhaled corticosteroids or azithromycin to see which is more effective.
Obesity, Metabolic Dysregulation and the Airway Epithelium in Asthmatics
Recruiting
This trial is looking for adults with asthma, obesity, and metabolic syndrome to study how these conditions affect airway health. Participants will undergo assessments related to their breathing and overall health.
Registry of Asthma Characterization and Recruitment 3 (RACR3)
Recruiting
This trial is looking for people with asthma to join a database for future studies. Participants will provide information but will not receive treatment as part of this registry.
Protocol CAUSE-03 / CHEETAH
Recruiting
This trial is looking for children and teenagers aged 6-17, some with asthma and some without. Participants will be monitored over a year while reporting on their cold symptoms and visiting the clinic at scheduled times.
A Study to Investigate GB-0895 Adjunctive Therapy in Adults and Adolescents With Severe Uncontrolled Asthma (SOLAIRIA-1)
Recruiting
This trial is looking for adults and teenagers with severe asthma that isn't controlled well by their current treatments. Participants will receive either the study drug GB-0895 or a placebo every six months for a year, with regular check-ins.
Randomised Clinical Trial to Investigate Efficacy and Safety of Benralizumab 30 mg SC as an add-on Therapy in Uncontrolled Eosinophilic Asthma Patients Treated With Medium-dose ICS-LABA Compared to Conventional Escalation to High-dose ICS-LABA Treatment
Recruiting
This trial is looking for people aged 12 to 75 with eosinophilic asthma that is not well controlled. Participants will receive an additional therapy called benralizumab while continuing their current asthma medication.
A Study of KT-621 Administered Orally to Adult Participants With Moderate to Severe Eosinophilic Asthma
Recruiting
This trial is looking for adults aged 18 to 75 who have moderate to severe eosinophilic asthma that is not well controlled. Participants will take a medication called KT-621 to see how well it works and monitor any side effects.

Asthma clinical trials in Colorado: common questions
How many Asthma clinical trials are recruiting in Colorado?
TrialFinder currently lists 22 recruiting Asthma clinical trials with study sites in Colorado. Results are updated regularly from ClinicalTrials.gov, the official U.S. registry of clinical studies.
Where are Asthma clinical trials located in Colorado?
Study sites for the Asthma trials listed on this page include Colorado Springs, Aurora, Denver. Each trial page lists every participating site with contact details, so you can find the location closest to you.
Do I need insurance to join a Asthma clinical trial in Colorado?
No. Study-related care is covered by the trial sponsor at no cost to participants, including the study treatment, required lab tests and study visits. Many Asthma trials in Colorado also compensate participants for time and travel. Health insurance is not required to search or enroll.
How do I qualify for a Asthma clinical trial in Colorado?
Each study sets its own criteria based on age, Asthma diagnosis details, prior treatments, current medications and general health. The fastest way to find out is to contact a research site directly — most will pre-screen you by phone in 10 to 15 minutes at no charge. You can also create a free TrialFinder profile to be matched automatically.
Do I need to stop my inhaler to join an asthma trial?
No. Trials add the study treatment to your maintenance inhaler, or replace it with a study-supplied version, and a rescue inhaler is always permitted. Any change is made by the study doctor.
What is an eosinophil count and why do trials ask about it?
It is a type of white blood cell measured in a routine blood test. Many biologic asthma drugs target the inflammation it signals, so trials set a minimum or maximum count. The site measures it at screening.
Are there asthma trials for children?
Yes. Biologics and inhalers approved for adults are studied in children aged 6 to 11 and in teenagers, with a parent consenting and attending visits. The listing states the age range.
