Further study details as provided by Royal Brompton & Harefield NHS Foundation Trust:

Primary Outcome Measures:
  • Change from baseline in airway cytokine levels at 3 months follow-up [ Time Frame: Baseline versus 3 months follow-up ]
    Change in airway cytokine levels measured using a multiplex assay, 3 months following interventional treatment


Secondary Outcome Measures:
  • Association between baseline cytokine levels and future exacerbation frequency at 3 months follow-up [ Time Frame: Baseline versus 3 months follow-up ]
  • Association between baseline cytokine levels and future decline in lung function at 3 months follow-up [ Time Frame: Baseline versus 3 months follow-up ]
  • Association between baseline microvesicle levels and future exacerbation frequency at 3 months follow-up [ Time Frame: Baseline versus 3 months follow-up ]
  • Association between baseline microvesicle levels and future decline in lung function at 3 months follow-up [ Time Frame: Baseline versus 3 months follow-up ]
  • Change from baseline in airway microvesicle levels at 3 months follow-up [ Time Frame: Baseline versus 3 months follow-up ]
    Change in airway microvesicle levels measured using flow cytometry, 3 months following interventional treatment
