Roflumilast in patients with advanced chronic obstructive pulmonary disease: towards a better-targeted use.

INTRODUCTION: For patients with chronic obstructive pulmonary disease (COPD), one of the main goals in its management is to reduce the number of disease exacerbations. Roflumilast is an anti-inflammatory compound used in patients with advanced COPD and chronic bronchitis in order to fulfill this objective. However, this is not always easily achieved due to the heterogeneity of the population. Clinical trial data can allow more in-depth analysis in order to identify predictors for maximal efficacy in different patient populations. Areas covered: A post hoc pooled data analysis derived from two large-scale randomized controlled trials helped to better define the disease subsets in which roflumilast would exert the maximal therapeutic effect. These are represented by patients with prior hospitalizations for COPD exacerbations and by patients with higher values for eosinophil blood count. This analysis is the focus of our key paper evaluation. Expert opinion: This pooled data analysis suggests that a phenotype/endotype guided therapy has the potential to be impactful on overall survival by reducing the number of exacerbations and increase the life span of patients.
