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

Summary

The objective of the REACT trial is to investigate the effect of roflumilast 500 μg tablets once daily versus placebo on exacerbation rate and pulmonary function in COPD patients who are concomitantly treated with a fixed combination of long-acting β2-agonists (LABA) and inhaled glucocorticosteroids (ICS). In addition, data on safety and tolerability of roflumilast will be obtained. An additional objective is to further characterize the population pharmacokinetic profile of roflumilast and roflumilast N oxide and to further characterize their pharmacokinetics/pharmacodynamics (PK/PD) relationship in terms of efficacy and relevant safety aspects. Patients to be included are required to have severe COPD associated with chronic bronchitis and a history of frequent exacerbations and must be concomitantly treated with a fixed combination of LABA and ICS. Two parallel treatment arms (roflumilast 500 μg once daily and placebo) are included.
