This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This trial tests whether adding the beta-blocker metoprolol to standard care can reduce a combined risk of death, COPD flare-ups, and heart-related hospitalizations in people with COPD who do not have known heart disease. About 1,700 adults with COPD will receive either metoprolol or usual care, and their outcomes will be tracked for one year. The goal is to see if this inexpensive drug can offer broader protection for COPD patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Metoprolol, a beta-blocker, added to standard COPD care
What this could lead to
If it works, this could offer a low-cost way to reduce hospitalizations and deaths in people with COPD, even without heart disease.
What could go wrong
This is a pragmatic, unblinded trial, so results may be influenced by expectations. Metoprolol can cause side effects like low blood pressure or fatigue, and may not benefit all COPD patients.
