Orange, CaliforniaAges 18 years+ - NCT04543461Recruiting
Lung health study for young adults in the U.S.
This study follows young adults to learn about lung health and risk factors. It may help researchers better understand how breathing symptoms and exposures affect future lung outcomes.
Los Angeles, CaliforniaAges 25–35 - 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.
Stanford, CaliforniaAges Any age - NCT07201922RecruitingPhase 3
Can a new pill help slow lung changes in people with family risk?
This trial tests a new drug called nerandomilast to see if it can slow down early lung changes in people who have a close family member with a type of lung scarring called pulmonary fibrosis. You may join if you are 40 or older, have a parent, sibling, or child with this condition, and have early signs of lung changes on a CT scan.
Los Angeles, CaliforniaAges 40 years+ - NCT05001009Enrolling by invitation
Goals of care conversation support for certain serious illnesses
This study helps primary care clinicians and their patients have structured “goals of care” conversations (about what matters most and care preferences). It may help you get clearer, earlier planning—especially if you have a serious illness and higher risk of hospitalization or death.
Palo Alto, CaliforniaAges 18 years+ - NCT07714252Enrolling by invitation
Virtual palliative care team for veterans with heart or lung disease
This study tests a virtual team of nurses and social workers who provide palliative care to veterans with heart failure, COPD, or interstitial lung disease. The goal is to improve quality of life by offering extra support at home.

What taking part in a lung diseases 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.
