Recruiting studies in Colorado
- NCT07052942RecruitingPhase 4

Denver, ColoradoAges 18–70 - NCT05272241Recruiting
Asthma registry that helps researchers learn about asthma
This study enrolls people in specific cities to collect health information that helps researchers better understand asthma and how to recruit future studies. It may help by improving knowledge about asthma types and care in real-world settings.
Aurora, ColoradoAges Any age - NCT07456033RecruitingPhase 3
Depemokimab for adults and teens with type 2 asthma
This study tests a new medicine called depemokimab, given as an injection, to see if it can reduce asthma attacks in people with a specific type of asthma (type 2 high). If you have had asthma for several years and have had recent attacks despite using regular inhalers, this trial might be an option for you.
Aurora, ColoradoAges 12 years+ - NCT07276724RecruitingPhase 3
Study of GB-0895 for severe uncontrolled asthma

Colorado Springs, ColoradoAges 12–80 - NCT07323654RecruitingPhase 2
Oral KT-621 for moderate to severe eosinophilic asthma
This trial tests an oral medication called KT-621 for people with moderate to severe eosinophilic asthma. It aims to see if the drug can help control asthma better than the standard inhaled treatments alone.

ENV-294 for moderate-to-severe asthma in adults
This trial tests an experimental drug called ENV-294 in adults with moderate-to-severe asthma. You may join if you are already using two kinds of inhalers regularly and have had at least one asthma flare-up in the past year that needed steroids or a hospital visit.
Colorado Springs, ColoradoAges 18–75 - NCT05757102RecruitingPhase 3
Test new inhaler combo versus standard inhaler in teens
This Phase 3 trial compares a triple inhaler (FF/UMEC/VI) against the usual double inhaler (FF/VI) to help control asthma symptoms and breathing tests in teens ages 12–17. It also checks how safe and tolerable the treatments are over the study period.
Colorado Springs, ColoradoAges 12–17 - NCT06664619RecruitingPhase 3
Study of a new combination inhaler for asthma
This study tests a new combination inhaler (fluticasone propionate and albuterol) for people with asthma age 12 and older. It helps see if this inhaler works better than a placebo in controlling asthma symptoms and preventing attacks.
Lakewood, ColoradoAges 12 years+ - NCT07219173RecruitingPhase 2
Study of brenipatide for uncontrolled moderate to severe asthma
This study tests an investigational drug called brenipatide for people with moderate to severe asthma that isn't well controlled by current medicines. The purpose is to see if it can reduce asthma attacks better than a placebo (inactive treatment).
Colorado Springs, ColoradoAges 18–75 - NCT06750289RecruitingPhase 3
Testing benralizumab for uncontrolled eosinophilic asthma
This study tests if adding a new injectable medicine (benralizumab) to your current medium-dose inhaler works better than simply increasing your inhaler dose to control hard-to-treat asthma. It may help people with a specific type of asthma linked to high eosinophil levels.
Denver, ColoradoAges 12–75 - NCT06977581RecruitingPhase 2
study of PF-07275315 for moderate-to-severe asthma
This study tests a new medicine called PF-07275315 for people with moderate-to-severe asthma that is not well controlled with their current inhalers. It is for adults who have had asthma for at least a year, have had recent flare-ups needing steroids, and are not taking other biologic treatments.
Colorado Springs, ColoradoAges 18–70 - NCT06609239Enrolling by invitationPhase 2
Long-term safety study of Lunsekimig for asthma
This trial tests the long-term safety and effectiveness of Lunsekimig, an investigational drug, for adults with asthma. It is for people who have already completed a previous Lunsekimig study and are on stable asthma medications.
Aurora, ColoradoAges 18 years+ - NCT04278404Recruiting
Drug safety study for children already on certain medicines
This study measures how certain medicines move through the body and checks their safety in children. It may help doctors better understand dosing and side effects in kids who are already receiving these treatments, or in some kids who recently tested positive for COVID-19.
Aurora, ColoradoAges birth–20 years - NCT07444567RecruitingPhase 3
Continuing benralizumab treatment after a previous study
This trial lets people who completed an earlier benralizumab study and are benefiting from the medicine keep receiving it. The goal is to provide ongoing access while we continue to monitor safety and effectiveness.
Aurora, ColoradoAges 6 years+ - NCT06136091Recruiting
Asthma study in select communities using a smartphone app

Aurora, ColoradoAges 6–17 - NCT03215836Recruiting
Study obesity and metabolism in adults with asthma

What taking part in a asthma study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there asthma clinical trials in Colorado?
- Yes. We're currently tracking 22 recruiting asthma studies with a site in Colorado, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a asthma study in Colorado?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in Colorado to take part?
- Not necessarily. These studies have a site in Colorado, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a asthma trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New asthma studies open in Colorado regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
