The aim of the study is to investigate the effect of roflumilast on exacerbation rate and pulmonary function in patients with chronic obstructive pulmonary disease (COPD). Roflumilast will be administered orally once daily in the morning at one dose level. The study duration will last up to 56 weeks. The study will provide further data on safety and tolerability of roflumilast.

Primary Outcome Measures:
  • Pre-bronchodilator Forced Expiratory Volume in First Second (FEV1) [ Time Frame: Change from baseline over 52 weeks of treatment ] [ Designated as safety issue: No ]
    Mean change from baseline during the treatment period in pre-bronchodilator FEV1 [L]

  • COPD Exacerbation Rate (Moderate or Severe) [ Time Frame: 52 weeks treatment period ] [ Designated as safety issue: No ]

    Mean rate of COPD exacerbations requiring oral or parenteral glucocorticosteroids (=moderate COPD exacerbations), or requiring hospitalization, or leading to death (=severe COPD exacerbations), per patient per year.

    A COPD exacerbation is an event in the natural course of the disease characterized by a change in the patient's baseline dyspnea, cough and/or sputum beyond day-to-day variability sufficient to warrant a change in management [American Thoracic Society (ATS) / European Respiratory Society (ERS) 2005].

Secondary Outcome Measures:
  • Post-bronchodilator FEV1 [L] [ Time Frame: Change from baseline over 52 weeks of treatment ] [ Designated as safety issue: No ]
    Mean change from baseline during the treatment period in post-bronchodilator FEV1 [L]

  • Time to Mortality Due to Any Reason [ Time Frame: 52 weeks treatment period ] [ Designated as safety issue: No ]
  • Natural Log-transformed C-reactive Protein (CRP) [ Time Frame: Change from baseline to last post randomization measurement (52 weeks) ] [ Designated as safety issue: No ]
    Mean change from baseline to the last post randomization measurement in natural log-transformed CRP

  • Mean Transition Dyspnea Index (TDI) Focal Score During the Treatment Period [ Time Frame: Change from baseline over 52 weeks of treatment ] [ Designated as safety issue: No ]

    The TDI is a recognized questionnaire to measure dyspnea in an out patient COPD population. At baseline, 3 components of dyspnea, each graded with 4 questions, were asked:

    • Functional Impairment
    • Magnitude of Task
    • Magnitude of Effort

    At each of the post-randomization visits questions from the TDI were asked related to 3 components:

    Change in

    • Functional Impairment
    • Magnitude of Task
    • Magnitude of Effort

    Each question in the TDI is graded from -3 (major deterioration) to +3 (major improvement). This results in a TDI Focal Score ranging from -9 to +9.
