Recruiting studies
- NCT07160868Recruiting
Sleep apnea and severe asthma study
This study looks at whether people with difficult-to-treat asthma might also have obstructive sleep apnea. If you're on high-dose asthma treatments, this trial could help find out if sleep problems are making your asthma worse.

This study uses special MRI and CT scans to take very detailed pictures of the lungs in people with mild asthma. The goal is to learn more about how asthma affects the lungs, which could help develop better treatments.
London, OntarioAges 17–35 - NCT07139899Recruiting
Mucus Plugs and Lung MRI in Severe Asthma
This study is looking at how mucus plugs in the airways affect lung function in people with severe asthma. If you are about to start a new injectable asthma treatment (dupilumab, tezepelumab, or benralizumab), you may be able to join and get a special type of lung MRI to see how your lungs are doing.
Durham, North CarolinaAges 18–65 - NCT07134686Recruiting
Combined lung and ear-nose-throat care for asthma and sinusitis
This trial tests if seeing a lung specialist and an ear-nose-throat doctor together in one visit helps people with asthma and chronic sinusitis (with nasal polyps) feel better than seeing each specialist separately. You may qualify if your asthma or sinusitis is not well-controlled and you've used steroid pills in the past year.

Study of SHR-1905 for severe uncontrolled asthma
This trial tests an experimental drug called SHR-1905 for people with severe asthma that is not well controlled by their current treatments. The study aims to see if the drug can reduce asthma attacks and improve breathing.
Guangzhou, GuangdongAges 18 years+ - NCT05364632Recruiting
Exercise training to improve activity in people with asthma
This trial compares an aerobic exercise program with a behavioral program to help increase physical activity in people with asthma. It may help you build safer activity habits, especially if your asthma symptoms are not well controlled.
São Paulo, São PauloAges 18–65 - NCT07047430Recruiting
Air quality near Sea-Tac airport and children's asthma
This study looks at how air quality near the airport affects children with asthma. Participating families help researchers understand if certain actions can reduce asthma flare-ups.
Seattle, WashingtonAges 6–12 - NCT07031102Recruiting
Methacholine challenge test for children with asthma
This study measures how children's airways respond to a substance called methacholine to understand how asthma affects lung function. It compares children with and without asthma to help improve diagnosis and treatment.
HelsinkiAges 7–15 - NCT07015749RecruitingPhase 1
IBI3002 for moderate to severe asthma
This trial tests a new drug called IBI3002 for people with moderate to severe asthma that isn't well controlled with standard inhalers. It aims to see if the drug is safe and tolerable when given multiple times.
Suzhou, JiangsuAges 18–65 - NCT07011524RecruitingPhase 2
Study of CM512 injection for moderate-to-severe asthma
This trial tests a new injection, CM512, for people with moderate-to-severe asthma that is not well controlled with current inhalers. It aims to see if the treatment can reduce asthma attacks and improve symptom control.
Guangzhou, GuangdongAges 18–75 - NCT06977581RecruitingPhase 2
Study of PF-07275315 for moderate-to-severe asthma
This study tests an investigational medicine called PF-07275315 for people with moderate-to-severe asthma that is not well controlled with current treatments. The goal is to see if it can reduce asthma attacks and improve breathing.
Mobile, AlabamaAges 18–75 - NCT06979323RecruitingPhase 3
Depemokimab study for asthma with imaging and bronchoscopy
This study tests depemokimab, an injectable biologic, to see how it works in the lungs of people with severe asthma. You would get the drug and have special imaging and a bronchoscopy (a tube with a camera placed into your airways to take tiny tissue samples) so doctors can understand how the medicine reduces inflammation.
Brooksville, FloridaAges 18 years+ - NCT06970080RecruitingPhase 4
Testing airway shape in adults with asthma
This trial uses advanced imaging to study the shape of airways in adults with asthma who have active symptoms and inflammation. It aims to find out if certain airway shapes affect how well treatments work, which could lead to more personalized asthma care.
Hamilton, OntarioAges 18 years+ - NCT03885245RecruitingPhase 2
L-citrulline supplement for overweight adults with later-onset asthma
This Phase 2 trial tests whether adding L-citrulline can improve asthma control in overweight adults whose asthma started later in life. It compares your asthma symptoms and lung testing results to see if the supplement helps when asthma is already being treated.
Durham, North CarolinaAges 18–65 - NCT06960382RecruitingPhase 1/Phase 2
Cat allergy immunotherapy with lymph node injections
This trial tests a new way to treat cat allergies by giving tiny injections directly into a lymph node (a part of your immune system), instead of under the skin. It aims to see if this method is safe and can reduce cat allergy symptoms, even in people with asthma.
ZurichAges 18–65 - NCT06932263RecruitingPhase 2

Common questions
- Are there clinical trials for asthma?
- Yes. Clin2 currently lists 385 recruiting asthma studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a asthma trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a asthma trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
