Phase 3 — Testing in thousands of people, comparing the treatment against what doctors currently use. This is the last big step before approval.

What is this trial?

This trial is testing a new medication called to see if it can help people with chronic obstructive pulmonary disease (COPD)—a serious lung condition that makes breathing difficult—when their current treatments aren't working well enough. The study focuses on people whose COPD involves a specific type of immune response in the blood. About 942 people will receive either the medication or a placebo (dummy injection) for 48 weeks to find out if this treatment is safe and effective.

Many people with severe COPD continue to struggle with breathing problems and frequent flare-ups even when taking multiple medications. This trial exists to find out whether this medication can help patients like these—especially those with a particular type of lung inflammation—breathe better and reduce how often they get worse.

Do you qualify?

You likely qualify if…

you are between 40 and 80 years old
you have had COPD diagnosed by a doctor for at least one year
you have a history of smoking (at least 10 pack-years: roughly 10 cigarettes a day for 10 years, or equivalent)
you are still having symptoms and flare-ups despite taking three different COPD medications regularly for at least 12 weeks
you had at least two moderate or one severe COPD flare-up in the past year
your blood work shows elevated eosinophil levels (a specific type of white blood cell) at 150 cells or higher

You likely don't qualify if…

you have asthma or asthma-COPD overlap syndrome
you are using high-flow oxygen therapy (more than 4 liters per minute) or need significant oxygen just to maintain safe oxygen levels at rest
you have active or untreated tuberculosis
you have a current or past history of cancer
you have taken a biologic therapy or strong immune-suppressing medication within the past 4 months

What participation looks like

If you join this study, you will receive subcutaneous injections (shots under the skin) of either the new medication or a placebo every few weeks for 48 weeks (about 12 months). You will visit the research clinic regularly so doctors can check how well the treatment works, monitor your breathing with lung tests, and watch for any side effects. Your participation will help doctors understand whether this new treatment can improve life for people with hard-to-control COPD.
