Further study details as provided by MedImmune LLC:

Primary Outcome Measures:
  • Identification of how inflammatory pathways differ in COPD subjects [ Time Frame: 6 weeks ]
    Identify how inflammatory pathways differ in subjects with COPD during an acute exacerbation relative to when the disease is stable.

Secondary Outcome Measures:
  • Biomarker Sample Repository [ Time Frame: 6 weeks ]
    Establish a biomarker sample repository to support future target validation for the treatment of subjects with COPD.

Biospecimen Retention:   Samples Without DNA
Blood, Endobronchial tissues and Bronchoalveolar (BAL) samples

Enrollment: 26
Study Start Date: April 2011
Study Completion Date: February 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
COPD subjects
Adult male and female subjects with COPD

Detailed Description:
This is an observational study in adult male and female subjects with COPD to collect blood, endobronchial tissues and BAL to investigate the inflammatory genes/pathways associated with AECOPD at the time of exacerbation (ie, active disease) and at 6 weeks later (ie, stable disease).

Ages Eligible for Study:   40 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Subjects referred to the hospital clinic with AECOPD

Inclusion Criteria:

  • Physician-diagnosed acute exacerbations of chronic obstructive pulmonary disease
  • Current or ex-smoker with a tobacco history of 15 or more pack years
  • Females of childbearing potential must use birth control for the duration of the study.

Exclusion Criteria:

  • Evidence or history of clinically significant disease
  • Subjects with asthma
  • Subjects taking anti-leukotriene medications
