Evaluation of the Effect of Roflumilast in Hyperinflated COPD Patients Using Functional Respiratory Imaging

Placebo Controlled Study to Assess the Effect of Roflumilast in Hyperinflated COPD Patients in Addition to LABA/LAMA Therapy Using Functional Respiratory Imaging.

In this study the efficacy of Roflumilast in addition to LAMA/LABA therapy will be assessed using Functional Respiratory Imaging.

In total 40 Chronic obstructive pulmonary disease (COPD) patients, Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages C and D, who are stable on LABA/LAMA therapy and who are prone to dynamics hyperinflation will be included in this study. To indicate the susceptibility to dynamics hyperinflation patients should have a baseline Borg Fatigue score after the 6-minute walk test (6MWT) above 4.

The patients will be randomized in such a way that 1 out of 2 patients will receive placebo and 1 the active component.

Image parameters will be assessed and the correlation with lung function and health related quality of life will be checked before and after treatment.

Inclusion Criteria:

• Male or female patient ≥ 30 years old
• Written informed consent obtained
• Patient with Body mass index (BMI) ≥ 20
• Female patient of childbearing potential who confirm that a contraception method was used at least 14 days before visit 1 and will continue to use a contraception method during the study
• COPD patient with GOLD stages C and D
• Patient with a Borg Fatigue score after the 6MWT on screening above 4 to indicate the susceptibility to dynamics hyperinflation
• Patient with smoking history of at least 10 pack-years
• Patient takes a combination therapy of LABA/ LAMA at least 6 weeks before visit 1
• Patient must be able to understand and complete the protocol requirements, instructions, questionnaires and protocol-stated restrictions

• Pregnant or lactating females
• Patient with severe immunological diseases and/ or severe acute infectious diseases
• Patient with heart failure as documented in the medical history or as defined by the investigator during the physical examination performed at visit 1

• Patient who received any investigational new drug within the last 4 weeks prior to the screening visit or twice the duration of the biological effect of any drug (whichever is longer)
