Study of Tezepelumab Compared to Placebo in Adults with Moderate to Very Severe Chronic Obstructive Pulmonary Disease (COPD)

3 1 1

What is this study about?

This clinical trial investigates the use of tezepelumab in adults with Chronic Obstructive Pulmonary Disease (COPD). COPD is a long-term lung condition that causes breathing difficulties and can lead to frequent chest infections. The study aims to determine if tezepelumab can reduce the frequency of COPD flare-ups compared to placebo in people with moderate to very severe forms of the disease.

The study medication tezepelumab is given as a subcutaneous injection using a pre-filled syringe. Some participants will receive tezepelumab, while others will receive a placebo. Neither the participants nor their doctors will know which treatment is being given during the study.

The treatment period will last for 76 weeks, during which participants will receive regular injections of either tezepelumab or placebo. Throughout the study, doctors will monitor participants’ breathing ability, symptoms, and how often they experience COPD flare-ups. The study will also track any changes in participants’ quality of life and their ability to perform daily activities.

1 Initial treatment phase

You will receive either tezepelumab or a placebo through subcutaneous injection (an injection under the skin).

The medication used is Tezspire 210 mg solution in a pre-filled syringe.

Your current inhaled therapy for Chronic Obstructive Pulmonary Disease (COPD) will continue during the study.

2 Treatment monitoring – First 52 weeks

Your lung function will be measured regularly using a test called FEV1 (amount of air you can forcefully exhale).

You will complete questionnaires about your symptoms and quality of life.

The medical team will monitor any COPD exacerbations (periods when your symptoms get worse).

Your blood will be tested to measure medication levels and check for antibodies.

3 Extended observation period

The study continues for an additional 24 weeks (total of 76 weeks).

During this time, the medical team will continue to monitor your COPD exacerbations.

The focus will be on tracking both moderate and severe episodes of symptom worsening.

Blood samples will continue to be collected to measure drug levels and antibodies.

4 Final evaluation

Your lung function will be measured one final time.

The medical team will review your complete health status.

All questionnaires about your symptoms and quality of life will be completed for the last time.

A final blood sample will be taken to check medication levels and antibodies.

Tezepelumab

Tezepelumab is a medication being studied for people with moderate to very severe Chronic Obstructive Pulmonary Disease (COPD). It is designed to reduce the frequency and severity of COPD flare-ups (exacerbations). This medication works by targeting specific proteins in the body that are involved in airway inflammation, which is a key feature of COPD. It is given to patients alongside their regular COPD treatments.

Chronic Obstructive Pulmonary Disease (COPD) – A progressive respiratory condition that makes breathing difficult due to obstruction of airflow in the lungs. The disease causes the airways to become inflamed and narrowed, while also damaging the tiny air sacs (alveoli) in the lungs. COPD typically develops slowly over years, with symptoms including persistent coughing, increased mucus production, wheezing, and shortness of breath, especially during physical activities. The condition often results in reduced lung function and can affect daily activities. The airways become less elastic over time, making it harder to breathe out properly.
