Inglewood, CaliforniaAges 40–85 - NCT07190222RecruitingPhase 3
New medicine for COPD with frequent flare-ups
This study tests a new medicine called Lunsekimig for people with COPD that has frequent flare-ups and high eosinophil levels (a sign of inflammation). It aims to see if it can help control symptoms better than a placebo (a dummy treatment).
Long Beach, CaliforniaAges 40–80 - NCT07190209RecruitingPhase 3
Testing lunsekimig for COPD with frequent flare-ups
This trial tests a new medicine called lunsekimig for people with COPD that still causes flare-ups despite standard treatment. It focuses on people with higher blood eosinophils (a type of white blood cell). If you smoke or used to smoke and have had at least 2 moderate or 1 severe flare-up in the past year, this study may be an option.
La Palma, CaliforniaAges 40–80 - NCT07177339RecruitingPhase 3

What taking part in a copd 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.
