Roflumilast in Chronic Obstructive Pulmonary Disease (COPD) Patients Treated With Fixed Dose Combinations of Long-acting β2-agonist (LABA) and Inhaled Corticosteroid (ICS)


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

To demonstrate the additional benefit of roflumilast when added on to fixed-dose combination (FDC) LABA/ICS in the reduction of exacerbations in subjects with severe to very severe COPD.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  1. Male or female patients at least 40 years of age
  2. History of COPD (according to GOLD 2010) for at least 12 months prior to Screening (Visit 1) associated with chronic productive cough for 3 months in each of 2 consecutive years (with other causes of productive cough excluded). Only patients with chronic bronchitis will be included (concomitant emphysema is permitted)
  3. Forced expiratory volume after 1 second (FEV1)/forced vital capacity (FVC) ratio (postbronchodilator) < 70% at Screening (Visit 1)
  4. FEV1 (postbronchodilator) ≤ 50% of predicted at Screening (Visit 1)
  5. At least two documented moderate or severe COPD exacerbations within 12 months prior to Screening (Visit 1)
  6. Patients must be on FDC LABA/ICS treatment ≥ 3 months prior to Screening (Visit 1)
  7. Former smokers (defined as smoking cessation at least 1 year ago) or current smokers (including patients who ceased smoking within the past year) both with a smoking history of at least 20 pack-years

Exclusion Criteria:

  1. Moderate or severe COPD exacerbation and/or COPD exacerbations treated with antibiotics or systemic glucocorticosteroids within 4 weeks of Screening (Visit 1) (ie, patients must be clinically stable)
  2. Known alpha-1-antitrypsin deficiency
  3. Current diagnosis of asthma (either controlled or uncontrolled) (Note: History of childhood asthma is not exclusionary.)
  4. Body mass index (BMI) ≥ 45 kg/m2
  5. Patients with a history (within 5 years) or current diagnosis of cancer other than basal or squamous cell skin cancer
