Personalized drug testing for cystic fibrosis using small trials
This trial tests how well cystic fibrosis (CF) medicine works for you using an “n-of-1” approach, meaning you try treatments in a structured, repeated way to see what helps you most. It may help your care team choose the best option for your specific CF genetics and health status.
Cincinnati, OhioAges 6 years+ - NCT05937815Recruiting
Study of Trikafta on Gut-Lung Connection in CF
This study is looking at how a new combination medicine (Trikafta) affects the lungs and gut in people with cystic fibrosis who carry the DeltaF508 mutation. It aims to understand how the medicine works in the body.
BordeauxAges 6–17 - NCT02270476Recruiting
Study of how cystic fibrosis lung disease changes over time
This observational study follows children newly diagnosed with cystic fibrosis to understand how their lung disease develops. It may help doctors better predict disease course and choose the right timing for care.
Heidelberg, Baden-WurttembergAges Any age - NCT05844449Enrolling by invitationPhase 3
Check long-term safety and effectiveness of CF medicines
This Phase 3 study looks at how well and how safely Vanzacaftor/Tezacaftor/Deutivacaftor works over the long term in people with cystic fibrosis who already took the study medicine before. It may help confirm the best long-term plan and spot important safety issues.
Orange, CaliforniaAges 1 year+ - NCT06996951RecruitingPhase 3
Sinus treatments in cystic fibrosis with modern modulator therapy
This study looks at how different sinus treatments affect people with cystic fibrosis who are taking modern modulator therapy. It aims to understand which rinses work best for chronic sinus problems.
Indianapolis, IndianaAges 18 years+ - NCT07442682Enrolling by invitation
Studying cystic fibrosis in adults at a Belgian center
This trial gathers information about adults with cystic fibrosis at the Erasme Hospital in Belgium. Your participation helps doctors better understand the condition and how it affects quality of life.
BrusselsAges 18 years+ - NCT05200429Recruiting
Study of long-term effects of CFTR modulator medicines in CF
This observational study follows people with cystic fibrosis (CF) to understand the long-term impact of CFTR modulator medicines. It may help researchers see how these treatments work over time in real life.
Vancouver, British ColumbiaAges Any age - NCT06457451Recruiting
Diet and exercise program for cystic fibrosis patients on Trikafta
This study tests whether a program combining diet advice and guided exercise can help people with cystic fibrosis who are already on Trikafta improve their lean muscle mass. Participants will be randomly assigned to receive the program or continue their usual care.
AngersAges 18 years+ - NCT07709494RecruitingPhase 1
Inhaled Rev-56 for healthy volunteers and people with bronchiectasis
This trial tests an inhaled drug called Rev-56 in healthy adults and in adults with non-cystic fibrosis bronchiectasis who have a chronic lung infection with Pseudomonas aeruginosa. It aims to see if the drug is safe, well-tolerated, and helps reduce the bacteria in the lungs.
Miami, FloridaAges 18–80 - NCT06356246Recruiting
Oral health survey for adults with cystic fibrosis
This study uses an online survey to learn about the oral health of adults with cystic fibrosis. Your answers can help doctors understand and improve dental care for people like you.
Ivry-sur-Seine, Île-de-France RegionAges 18 years+ - NCT05818319Recruiting
Tracking kidney urine effects after a short pause in CF therapy
This study checks how a common cystic fibrosis (CF) medicine affects urine markers after briefly stopping it and then restarting. The goal is to better understand whether the treatment shift changes kidney-related signals in people with CF.
Aarhus C, Central JutlandAges 18 years+ - NCT00001532Recruiting
How Genes Affect Lung Disease Development
This research study examines how genetic factors contribute to various lung diseases, including alpha-1 antitrypsin deficiency, cystic fibrosis, and chronic obstructive pulmonary disease. Researchers want to understand why some people develop lung disease and how genetics plays a role, which may help improve treatment in the future.
Bethesda, MarylandAges 2–90 - NCT04930289Enrolling by invitation
Lung transplant registry for better donor lung preservation
This study builds a worldwide database to track and improve how donor lungs are preserved before transplant. Your information may help doctors choose and manage donor lungs more effectively.

Study of the natural course of noncirrhotic portal hypertension
This study follows people with noncirrhotic portal hypertension (NCPH) or people at risk for it to better understand how the condition progresses over time. It does not sound like a medication trial—more like careful monitoring to learn what happens in different people.
Bethesda, MarylandAges 12–100 - NCT06528418Recruiting
Breath test to find lung diseases
This study uses a simple breath test to detect different lung diseases. By analyzing the chemicals in your breath, researchers hope to find a faster, non-invasive way to diagnose lung conditions. It may be an option if you have a known lung disease and have a recent CT scan.
Guangzhou, GuangdongAges 18–100 - NCT04538859Recruiting
Study of causes of flare-ups and death in bronchiectasis

Common questions
- Are there clinical trials for cystic fibrosis?
- Yes. Clin2 currently lists 155 recruiting cystic fibrosis 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 cystic fibrosis 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 cystic fibrosis 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.
