Study Summary
The purpose of this Phase III study is to evaluate the efficacy and safety of tozorakimab Dose 1 and Dose 2 administered subcutaneously (SC) in adult participants with symptomatic COPD and history of ≥ 2 moderate or ≥ 1 severe exacerbation of COPD in the previous 12 months. Participants should be receiving optimised treatment with maintenance inhaled therapy (ICS/LABA/LAMA triple therapy, or dual therapy if triple is not considered appropriate) in stable doses throughout at least 3 months prior to enrolment.
Primary Outcome
The primary endpoint will be assessed first in the primary population (former smokers with symptomatic COPD and a history of exacerbations, on optimised treatment with maintenance inhaled therapy \[triple therapy, or dual therapy if triple is not considered appropriate\]) and then assessed in the overall population of participants.
