New COPD treatment cuts hospital returns in severe cases

This study tested whether a drug called mepolizumab, given after a severe COPD flare-up that required hospital care, could prevent future hospital stays or death. It involved 238 adults with eosinophilic COPD (a type with high levels of certain white blood cells). Participants received either mepolizumab or a placebo alongside standard care. The goal was to see if the drug could reduce the risk of another hospital visit or death over about a year.
