Researchers are evaluating the efficacy and safety of tezepelumab in adults with moderate to very severe chronic obstructive pulmonary disease COPD who are receiving inhaled maintenance therapy. This Phase 3, multicenter, randomized, double-blind, placebo-controlled study focuses on adults aged 40 to 80 years who have experienced multiple COPD exacerbations in the year prior to enrollment. The trial aims to assess tezepelumabs impact compared to placebo on COPD exacerbations and lung function. Participants will receive monthly subcutaneous injections of one of two doses of tezepelumab or a matching placebo. Treatment duration ranges from a minimum of 52 weeks to a maximum of 76 weeks. Following the treatment period, participants will undergo a 12-week off-treatment safety follow-up to monitor any lasting effects. Throughout the study, participants will be regularly assessed for COPD exacerbations, lung function changes measured by forced expiratory volume FEV1, and quality of life using questionnaires such as the St. Georges Respiratory Questionnaire and COPD Assessment Test. Blood samples will be collected to measure drug levels and immune responses. Safety and efficacy will be closely monitored, with total participation lasting up to approximately 88 weeks including follow-up.
