Evaluating Tezepelumab for Adults with Moderate to Very Severe COPD

A Randomised, Double-blind, Placebo-controlled, Parallel Group, Multicentre, Phase III Study to Evaluate the Efficacy and Safety of Tezepelumab in Adult Participants With Moderate to Very Severe Chronic Obstructive Pulmonary Disease

PHASE3 · AstraZeneca · NCT06883305

This study is testing if a new medication called tezepelumab can help adults with moderate to very severe COPD feel better and reduce flare-ups compared to a placebo.

What this trial studies

This Phase 3 clinical trial investigates the efficacy and safety of tezepelumab in adults diagnosed with moderate to very severe chronic obstructive pulmonary disease (COPD). Participants will be randomly assigned to receive either tezepelumab or a placebo through monthly subcutaneous injections over a treatment duration of 52 to 76 weeks. The study aims to include individuals who have experienced multiple COPD exacerbations in the past year while on inhaled maintenance therapy. An off-treatment safety follow-up period of 12 weeks is also included to monitor any long-term effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40 to 80 with a confirmed diagnosis of COPD who have experienced at least two moderate or one severe exacerbation in the past year.

Not a fit: Patients with other significant pulmonary diseases or those with a history of asthma or malignancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of COPD and reduce exacerbations in affected patients.

How similar studies have performed: Other studies have shown promise with similar monoclonal antibody approaches in treating COPD, indicating potential for success.
