  • Post-bronchodilator FEV1/FVC ratio of <0.7
  • Post-bronchodilator FEV ≥40 % and ≤80 % of predicted normal values calculated using NHANES reference equations.
  • Additional Inclusion for Smoking COPD Subjects 1. Must have smoked regularly in the 12-month period preceding the screening visit and have a pack history of ≥ 5 pack years (number of pack years = number of cigarettes per day/20 x number of years smoked).

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Lipid metabolites in sputum cell homogenate from healthy smokers and smokers and ex-smokers with COPD. (time frame: 8 months). It is what the study was designed to measure, not a finding.
