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.

Primary Outcome Measures:
  • Change in sputum neutrophil counts [cells/g sputum] from Day 1 to Day 14 post exacerbation [ Time Frame: Day 1 to Day 14 ] [ Designated as safety issue: No ]
    Assessment will be done at Day 14 after randomisation

Secondary Outcome Measures:
  • Change in sputum inflammatory markers [ Time Frame: Day 1 to Day 7, Day 14, Day 28, Day 56 ] [ Designated as safety issue: No ]
    • Change for the following sputum inflammatory markers:

      • total and differential cell counts (absolute [cells/g sputum] and percentage [%])

        • neutrophils (except for change addressed in primary outcome)
        • macrophages
        • eosinophils
        • lymphocytes
      • Sputum concentrations of interleukin (IL)-6, IL-8, myeloperoxidase (MPO), neutrophil elastase.
    • Proportion of patients whose sputum neutrophil counts have returned to stable state levels at Day 14 post exacerbation.

  • Change in blood biomarkers [ Time Frame: Day 1 to Day 7, Day 14, Day 28, Day 56 ] [ Designated as safety issue: No ]

    Change for the blood concentration of the following biomarkers:

    • C-reactive protein (CRP)

    • fibrinogen

    • IL-6 and IL-1β

    • glucose

  • Change in pulmonary function [ Time Frame: Day 1 to Day 7, Day 14, Day 28, Day 56 ] [ Designated as safety issue: No ]

    Change for the following spirometry measurements:

    • Forced expiratory volume in the first second (FEV1)

    • forced vital capacity (FVC)

    • FEV1/FVC

  • Diary outcomes [ Time Frame: During treatment and follow-up period (up to 56 days) ] [ Designated as safety issue: No ]

    Diary outcomes will include the following:

    • outcomes with respect to exacerbations
    • time course on a daily basis and changes on a weekly basis for PEF, respiratory symptoms and hours spent out of house

  • Patient-reported outcomes [ Time Frame: During treatment and follow-up period (up to 56 days) ] [ Designated as safety issue: No ]

    Time course on a daily basis and changes on a weekly basis for the following:

    • COPD Assessment Test (CAT)

    • EXAcerbations of Chronic pulmonary disease Test-Patient-Reported Outcome (EXACT-PRO) questionnaire.

  • Change from Baseline in aortic pulse wave velocity in a subset of participants [ Time Frame: Baseline and Days 14 and 28. ] [ Designated as safety issue: No ]
    Carotid-femoral aortic pulse wave velocity (aPWV) will be measured in a subset of participants to determine changes in arterial stiffness.

Enrollment: 95
Study Start Date: February 2012
Study Completion Date: March 2014
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Roflumilast
added on to standard therapy for acute COPD exacerbations
Drug: Roflumilast
500 µg tablet, od, oral administration in the morning after breakfast
Placebo Comparator: Placebo
added on to standard therapy for acute COPD exacerbations
Drug: Placebo
tablet, od, oral administration in the morning after breakfast

Detailed 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.


Ages Eligible for Study:   40 Years and older   (Adult, Senior)
Genders Eligible for Study:   Both
