A 12-week Study Treating Participants Who Have alpha1-antitrypsin-related COPD With Alvelestat (MPH966) or Placebo.

Purpose

The purpose of this study is to investigate the effect of alvelestat (an oral neutrophil elastase inhibitor) on blood and sputum biomarkers in patients with PiZZ, null or rare variant phenotype/genotype alpha-1 anti-trypsin deficient lung disease. Change in a number of different blood and sputum biomarkers related to lung damage, inflammation and elastase activity will be measured over a 12 week period. The effect on lung function and respiratory symptoms will also be measured.
