Kronisk luftvejssygdom, slimreologi og eksacerbationer (COPD-CARhE)

21. september 2026 opdateret af: University Hospital, Montpellier

Kronisk luftvejssygdom, slimreologi og eksacerbationer: et randomiseret kontrolleret forsøg med KOL-patienter

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.

Detaljeret beskrivelse

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).

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: Azithromycin according to symptoms

Patients randomized to this arm will be prescribed azithromycin in function of their symptoms.
Medicin: Azithropycin according to symptoms

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.
Eksperimentel: Azithromycin according to rheology

Patients randomized to this arm will be prescribed azithromycin in function of their sputum rheology.
Medicin: Azithromycin according to rheology or symptoms

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.

Foranstaltningsbeskrivelse
Tidsramme
The main outcome measure is the number of exacerbations over the 12 months of follow-up.
Tidsramme: 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)."

It also includes a single item that provides an indication of perceived change in health. A score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.

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.

Plan for individuelle deltagerdata (IPD)

Planlægger du at dele individuelle deltagerdata (IPD)?

JA

IPD-planbeskrivelse

The general goal is to make the study data available to interested researchers as well as to provide proof of transparency for the study. Data (and an accompanying data dictionary) will be de-identified and potentially further cleaned or aggregated as the investigators deem necessary to protect participant anonymity.

Data will be made available to persons who address a reasonable request to the study director and fulfil the requirements stipulated by the French CNIL (Commission Nationale de l'Informatique et des Libertés : https://www.cnil.fr/professionnel).

IPD-delingstidsramme

As close to "real time" as possible, the following supporting information will be made public:

  • Study Protocol (to be published in an appropriate journal).
  • Statistical Analysis Plan
  • Participant Information materials
  • Analytic code

These will be posted and registered on osf.io and/or clinicaltrials.gov (if not published).

Datasets can be requested after the publication process has been completed.

IPD-delingsadgangskriterier

The conditions under which members of the public will be granted access to datasets are:

  • The data will be used/examined in a not-for-profit manner;
  • The data will not be used in an attempt to identify a participant or group of participants;
  • The user does not work for a private insurance company;
  • The data will not be used in support of any kind of private insurance policy or health penalties;
  • The data will be used/examined for the advancement of science/teaching while respecting participant/patient privacy and rights;
  • The user will state why they wish to access the data.
  • The appropriate CNIL approval has been obtained by the user.
