Brief Summary:
The purpose of this Phase III study is to evaluate the efficacy and safety of tozorakimab administered subcutaneously (SC) in adult participants with symptomatic COPD with a history of ≥ 2 moderate or ≥ 1 severe exacerbations of COPD in the 12 months prior to enrolment. Participants should be receiving optimised treatment with inhaled maintenance therapy (ICS/LABA/LAMA triple therapy, or dual therapy if triple is not considered appropriate) throughout at least the last 3 months prior to enrolment.
