Details and patient eligibility

About

The purpose of this trial is to investigate if roflumilast can reduce the neutrophilic inflammation at acute exacerbations of Chronic Obstructive Pulmonary Disease (COPD). In addition, the potential benefit of roflumilast on severity and recovery periods of acute COPD exacerbations will be assessed using patient diaries and questionnaires.

Full description

Participants will be asked whether they agree to participate in the measurements of arterial stiffness. Participants who agree will be included in the substudy, with the target of 60 patients with arterial stiffness measurements to complete the trial.

Study was terminated due to difficulty in identifying further eligible patients for this exploratory study within a reasonable time.
