Brief Summary:
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.

Primary Outcome Measures :
  1. Change from baseline on blood biomarkers of neutrophil elastase activity compared to baseline and placebo [ Time Frame: 12 weeks ]

    Within-individual change from baseline up to end of treatment in:

    • Blood neutrophil elastase activity
    • Blood Aα-Val 360 levels
    • Plasma desmosine/isodesmosine levels


Secondary Outcome Measures :
  1. Change from baseline on other blood biomarkers of neutrophil elastase activity [ Time Frame: 12 weeks ]
    Frequency of neutrophil elastase levels below the limit of detection from baseline to end of treatment


Other Outcome Measures:
  1. Change from baseline in St. George's Respiratory Questionnaire (SGRQ-C) to end of treatment [ Time Frame: 12 weeks ]
    Total score

  2. Change from baseline in pulmonary function [ Time Frame: 12 weeks ]
    Change from baseline in forced expiratory volume in 1 second (FEV1)
