Study of dupilumab injections to reduce airway inflammation in adults aged 40-85 with chronic obstructive pulmonary disease

3 1 1

What is this study about?

This study focuses on patients with Chronic Obstructive Pulmonary Disease (COPD), a long-term lung condition that causes breathing difficulties. The research examines the effects of dupilumab, given as an injection under the skin, compared to a placebo. The purpose is to evaluate how this medication affects inflammation in the airways, particularly looking at mucus buildup in the lungs.

The study involves patients who have moderate to severe COPD and show specific signs of inflammation in their blood. During the study, participants receive either dupilumab (also known as SAR231893) or a matching placebo as injections under the skin for 24 weeks. The medication is provided in pre-filled syringes, and participants continue taking their regular COPD medications throughout the study.

The research uses special lung imaging techniques to examine how the treatment affects mucus in the airways. High-resolution Computed Tomography (HRCT) scans are used to look at changes in the lungs over the course of treatment. The study also monitors the safety of the treatment and any changes in breathing ability.

1 Initial assessment

You will undergo an evaluation to confirm your eligibility for the study, including verification of chronic obstructive pulmonary disease (COPD) diagnosis

Your medical history will be reviewed, including smoking history of at least 10 pack-years

Blood tests will be performed to check your eosinophil levels (type of white blood cells)

A high-resolution computed tomography (HRCT) scan will be performed to assess mucus in your lungs

2 Treatment assignment

You will be randomly assigned to receive either dupilumab or placebo

The medication will be provided as an injection under the skin (subcutaneous use)

You will continue your regular COPD medications throughout the study

3 Treatment period

The treatment period will last 24 weeks

You will receive regular injections of either dupilumab or placebo

Your current COPD medications will continue, including triple therapy (three different types of inhaled medications) or dual therapy if needed

4 Monitoring and assessments

Regular tests will be performed to measure your lung function

You will undergo forced oscillation technique (FOT) tests to measure airway resistance

Additional HRCT scans will be performed to track changes in mucus levels and airway wall thickness

Any side effects or health changes will be monitored and recorded throughout the study

5 Final evaluation

At week 24, final assessments will be performed

These will include HRCT scans, lung function tests, and blood tests

The results will be compared to your initial measurements to evaluate the treatment effects

Must be using three types of inhaled medications for at least 3 months, with stable dosing for at least 1 month before study start (or two types if unable to use inhaled steroids)
Must have elevated levels of specific white blood cells (eosinophils) showing either:
- 300 or more cells per microliter at screening, or
- 150 or more cells per microliter at screening with previous history of 300 or more cells in the past year
Must have a mucus score of 3 or higher on medical imaging
Must be an adult (18 years or older)
Can be either male or female

Trial locations

Investigated drugs:

Dupilumab is a medication used to treat inflammation in the airways. It works by blocking certain proteins in the body that cause inflammation. In this trial, it is being studied for its effects on reducing mucus plugging in the lungs of patients with chronic obstructive pulmonary disease (COPD). The medication helps decrease inflammation in the airways and may improve breathing by reducing the amount of mucus that builds up in the lungs.

Investigated diseases:

Chronic obstructive pulmonary disease

Respiratory tract disease – A condition affecting the airways and other structures of the respiratory system, from the nasal passages to the lungs. It involves the accumulation of mucus in the airways, which can lead to breathing difficulties. The condition can cause changes in airway wall thickness and affect normal respiratory function. Respiratory tract disease often involves increased airway resistance and changes in lung tissue that can be observed through medical imaging. The condition may be characterized by ongoing inflammation of the respiratory passages.
