A Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel Group, Phase 2a Study to Explore the Efficacy and Safety of Tezepelumab in Adults with Moderate to Very Severe Chronic Obstructive Pulmonary Disease (COPD)


This is a Phase 2a, multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety and efficacy of tezepelumab in adults with moderate to very severe chronic obstructive pulmonary disease (COPD) receiving triple inhaled maintenance therapy, and having had 2 or more documented COPD exacerbations in the 12 months prior to Visit 1. Approximately, 338 subjects will be randomized globally. Subjects will be stratified by region and prior number of exacerbations (2 vs. 3 or more). Subjects will receive tezepelumab, or placebo, administered via subcutaneous injection at the study site, over a 52 week treatment period. The study also includes a post-treatment follow-up period of 12 weeks.
