This trial targets 961 participants in total. It began in 2025-06-23 with a primary completion date of 2028-12-13.

Brief Summary

Depemokimab is being developed as a treatment for individuals with moderate to severe COPD. The aim of this study is to assess the efficacy and safety of depemokimab compared as an add-on medicine in participants with uncontrolled moderate to severe COPD with type 2 inflammation.
