About this study
Official title: Chronic Airway Disease, Mucus Rheology and Exacerbations: a Randomized Controlled Trial of COPD Patients
The main objective of this trial is to compare the exacerbation number over 12 months of follow-up between a group of patients with COPD treated according to standardized management (azithromycin prescribed in the event of severe sputum according to the CASA-Q score , standardized comparator arm) and a similar group in which azithromycin is prescribed based on mucus rheology (experimental arm) or CASA-Q.
Read the detailed description
The secondary objectives are to compare between the 2 arms:
- exacerbation number according to their severity (observed throughout the duration of the study);
- the evolution of the symptoms, the rheology of the sputum, and the pulmonary function (measurements repeated every three months);
- medication consumption and adverse events (monitored throughout the duration of the study);
- patient trajectories during follow-up;
- the overall clinical improvement at the end of the study and the evolution of the quality of life (measurements repeated every 3 months);
- the change in biomarkers of interest (baseline versus end of study).
- Conditions
- Chronic Obstructive Pulmonary Disease
- Being tested
- Azithropycin according to symptoms, Azithromycin according to rheology or symptoms
- Medical subject headings
- Pulmonary Disease, Chronic Obstructive
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Azithropycin according to symptomsDrug
Patients randomized to the "standardized comparator arm" will benefit from the standard treatment for COPD, including with regard to the prescription of azithromycin in case of severe sputum complaints (here defined by a CASA-Q sputum symptoms score <70 to homogenize practices between centers).
CASA-Q will be evaluated every 3 months.
- If the patient has a sputum symptoms score <70, a prescription for 3 months of azithromycin treatment will be initiated. This prescription can be renewed every 3 months during the 12 months of follow-up planned in this study, if the patient continues to obtain a sputum symptoms score <70.
- If the patient has a sputum symptoms score> 70, management is not changed.
Azithromycin according to rheology or symptomsDrug
Treatment according to standard COPD management, except for the prescription of azithromycin, which will be prescribed in function of mucus rheology or as a function of sputum complaints (here defined by a CASA-Q sputum symptoms score <70).
The rheology of mucus will be quantified every 3 months.
- If the patient has spontaneous or induced sputum, and this sputum has a critical constraint (tau-C) > 39, a prescription for 3 months of azithromycin treatment will be initiated. This prescription may be renewed every 3 months during the 12 months of follow-up planned in this study.
- If the patient has a sputum symptoms score <70, a prescription for 3 months of azithromycin treatment will be initiated. This prescription can be renewed every 3 months during the 12 months of follow-up planned in this study, if the patient continues to obtain a sputum symptoms score <70.
- If the patient has a sputum symptoms score> 70, management is not changed.
| Study group | Role | What they receive |
|---|---|---|
| Azithromycin according to symptoms | Active comparator | Patients randomized to this arm will be prescribed azithromycin in function of their symptoms. Receives: Drug: Azithropycin according to symptoms |
| Azithromycin according to rheology | Experimental | Patients randomized to this arm will be prescribed azithromycin in function of their sputum rheology. Receives: Drug: Azithromycin according to rheology or symptoms |
What is being measured
The primary outcome is the main question the study is designed to answer.
The main outcome measure is the number of exacerbations over the 12 months of follow-up.
An exacerbation is defined according to French recommendations as an "acute event characterized by worsening of respiratory symptoms (notably cough, sputum and dyspnea) beyond [normal] daily variation and leading to a modification of treatment: either a simple increase in bronchodilators (in this case, a duration greater than 24 hours is required to define an exacerbation) or the addition of another treatment (antibiotic therapy and / or oral corticosteroid therapy)."
Measured: 12 months
Secondary outcomes (116)
The number of mild exacerbations throughout follow-up
A mild exacerbation does not require new additional medicine.
Measured: 12 months
The number of moderate exacerbations throughout follow-up
Moderate exacerbations require antibiotics or oral corticosteroids (but not hospitalization).
Measured: 12 months
The number of severe exacerbations throughout follow-up
Severe exacerbations require hospitalization.

EQ-5D-5L
In its original version, this self-administered questionnaire consists of two pages: the first contains the EQ-5D descriptive system and the second a visual analogue scale. The descriptive system has five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), each described by five levels of intensity ("no problems", "slight problems", "moderate problems", "severe problems" and "extreme problems or complete inability"). The respondent must indicate one intensity level for each dimension.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The main objective of this trial is to compare the exacerbation number over 12 months of follow-up between a group of patients with COPD treated according to standardized management (azithromycin prescribed in the event of severe sputum according to the CASA-Q score , standardized comparator arm) and a similar group in which azithromycin is prescribed based on mucus rheology (experimental arm) or CASA-Q.
Detailed description
The secondary objectives are to compare between the 2 arms:
- exacerbation number according to their severity (observed throughout the duration of the study);
- the evolution of the symptoms, the rheology of the sputum, and the pulmonary function (measurements repeated every three months);
- medication consumption and adverse events (monitored throughout the duration of the study);
- patient trajectories during follow-up;
- the overall clinical improvement at the end of the study and the evolution of the quality of life (measurements repeated every 3 months);
- the change in biomarkers of interest (baseline versus end of study).

Interventions
| Intervention | Type | Arms |
|---|---|---|
| Azithropycin according to symptomsPatients randomized to the "standardized comparator arm" will benefit from the standard treatment for COPD, including with regard to the prescription of azithromycin in case of severe sputum complaints (here defined by a CASA-Q sputum symptoms score <70 to homogenize practices between centers). CASA-Q will be evaluated every 3 months. * If the patient has a sputum symptoms score <70, a prescription for 3 months of azithromycin treatment will be initiated. This prescription can be renewed every 3 months during the 12 months of follow-up planned in this study, if the patient continues to obtain a sputum symptoms score <70. * If the patient has a sputum symptoms score> 70, management is not changed. | Drug | Azithromycin according to symptoms |
| Azithromycin according to rheology or symptomsTreatment according to standard COPD management, except for the prescription of azithromycin, which will be prescribed in function of mucus rheology or as a function of sputum complaints (here defined by a CASA-Q sputum symptoms score <70). The rheology of mucus will be quantified every 3 months. * If the patient has spontaneous or induced sputum, and this sputum has a critical constraint (tau-C) > 39, a prescription for 3 months of azithromycin treatment will be initiated. This prescription may be renewed every 3 months during the 12 months of follow-up planned in this study. * If the patient has a sputum symptoms score <70, a prescription for 3 months of azithromycin treatment will be initiated. This prescription can be renewed every 3 months during the 12 months of follow-up planned in this study, if the patient continues to obtain a sputum symptoms score <70. * If the patient has a sputum symptoms score> 70, management is not changed. | Drug | Azithromycin according to rheology |
Primary outcome
The main outcome measure is the number of exacerbations over the 12 months of follow-up.
Time frame: 12 months
An exacerbation is defined according to French recommendations as an "acute event characterized by worsening of respiratory symptoms (notably cough, sputum and dyspnea) beyond [normal] daily variation and leading to a modification of treatment: either a simple increase in bronchodilators (in this case, a duration greater than 24 hours is required to define an exacerbation) or the addition of another treatment (antibiotic therapy and / or oral corticosteroid therapy)."
