Study of PF-08634404 for early-stage or locally advanced lung cancer
This trial tests a new drug, PF-08634404, alone or with other treatments, for people with early-stage or locally advanced non-small cell lung cancer (NSCLC) that can be surgically removed or has been treated with radiation and chemo. It aims to find if the drug helps before or after surgery or after standard treatments.
Stanford, CaliforniaAges 18 years+ - NCT07179380RecruitingPhase 3
Inhaled treprostinil for pulmonary hypertension related to interstitial lung disease
This study tests an inhaled powder medication called TPIP (treprostinil palmitil inhalation powder) to see if it can improve symptoms and exercise ability in people who have both interstitial lung disease and pulmonary hypertension. The study will compare TPIP against a placebo (a dummy treatment without the active drug) to understand how well it works and if it is safe.
Fresno, CaliforniaAges 18 years+ - NCT01915511Recruiting
Long-term registry for new or worsening lung scarring
This study collects health information over time from people with newly diagnosed idiopathic pulmonary fibrosis (IPF) or other lung scarring diseases that are getting worse. It’s meant to better understand disease patterns and outcomes, which may help doctors plan future care.
Los Angeles, CaliforniaAges 21 years+ - NCT06911632Recruiting
AI-assisted check for pulmonary hypertension in interstitial lung disease
This study uses an AI tool to help doctors decide if you should be tested for pulmonary hypertension (high blood pressure in the lungs), which can be a complication of interstitial lung disease. If the tool suggests you might have it, you may get an echocardiogram (an ultrasound of the heart) and a right heart catheterization (a test to measure pressure in the heart) to find out for sure.
Riverside, CaliforniaAges 18 years+ - NCT07175038RecruitingPhase 2
Study of a new pill for pulmonary hypertension

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.
