Phase 3 Study to Assess the Safety and Effectiveness of Tezepelumab in Adults Aged 40 to 80 with Moderate to Very Severe Chronic Obstructive Pulmonary Disease

What this Trial Is About

Researchers are evaluating the safety and effectiveness of tezepelumab in adults aged 40 to 80 years with moderate to very severe chronic obstructive pulmonary disease COPD. This phase 3, multicenter, randomized, double-blind, placebo-controlled study focuses on participants already receiving inhaled maintenance therapy and who have experienced multiple COPD exacerbations in the previous year. The trial aims to understand tezepelumabs impact on reducing COPD flare-ups and improving lung function compared to placebo. Participants are randomly assigned to receive monthly subcutaneous injections of one of two doses of tezepelumab or a matching placebo. The treatment period lasts between 52 and 76 weeks, followed by a 12-week safety monitoring period without treatment. Throughout the study, participants continue their inhaled COPD therapies, and their health is closely tracked to assess the study drugs effects. During the trial, participants will undergo various assessments including lung function tests, questionnaires measuring respiratory symptoms and quality of life, and blood tests to monitor drug levels and immune responses. Researchers will measure the annual rate of moderate or severe COPD exacerbations and other health outcomes over the study period. Safety will be monitored throughout treatment and during the follow-up period, with visits scheduled regularly to collect data and support participant care.
