Reporting Groups
  Description
All Participants

Roflumilast. 500 mcg of Roflumilast daily for 4 weeks, then there will be a 4 week wash-out phase (no medication) and a second 4 week period of placebo.

Roflumilast: 500 mcg of Roflumilast which is a prescription medicine used in adults with severe Chronic Obstructive Pulmonary Disease (COPD) to decrease the number of flare-ups or the worsening of COPD symptoms

Placebo: 500 mcg of placebo is used
