Please assess the completion status of the following clinical trial:

Trial Title: Evaluation of Airway Gene Expression in COPD and Controlled Populations

Study Design Characteristics:
- Allocation: None
- Intervention Model: None
- Observational Model: COHORT
- Primary Purpose: None
- Time Perspective: PROSPECTIVE
- Masking: None
- Phase: None
- Number of Arms: None

Eligibility Criteria:
Inclusion Criteria:~* Age 45-70 yrs of age, incl, women as described above as far as child-bearing potential and subjects who if they have coexisting disease, the disease is stable and does not place an untoward risk or result in compromise of data.~* Non smokers will be lifelong and have not worked in a chronic dusty environment.~* Smokers will require a minimum of 10 pkyr history and currently smoking at least a pack per day. The smokers without symptoms of COPD must demonstrate a pulmonary function with an FEV1 \> 80%. The FEV1/FVC ratio may be less than .7 however they can not demonstrate symptoms of chronic bronchitis by medical history. Smokers with symptoms must demonstrate an FEV1 \< 80% and FEV1/FVC \<.7.~Exclusion Criteria:~* Any female subject who is pregnant or breast-feeding or a female subject who is of child-bearing potential who is unwilling to sue two acceptable methods of birth control.~* Any condition that would place the subject at risk for endobronchial brushings(such as bleeding diathesis) or subjects who are currently taking anticoagulants.~* Any subject who has had an exacerbation of COPD within the last six months of screening or who has been hospitalized for any reason within the last three months.~* Illicit substances indicated by positive urine drug screen.

- Gender: ALL
- Minimum Age: 45 Years
- Maximum Age: 70 Years
- Healthy Volunteers: t

Study Arms:
- methodologies to identify characteristics of non-smokers with normal lung function (Type: None): Imaging, genomic and proteomic methodologies to identify characteristics of individuals with normal lung function who do not smoke
- methodologies to identify characteristics of smokers but do not demonstrate symptoms of COPD (Type: None): Imaging, genomic and proteomic methodologies to identify characteristics of individuals who smoke but who do not demonstrate symptoms of chronic obstructive pulmonary disease
- methodologies to identify characteristics of smokers that demonstrate symptoms of COPD (Type: None): Imaging, genomic and proteomic methodologies to identify characteristics of individuals who smoke that demonstrate symptoms of COPD

Based on this trial design, predict the completion outcome and termination type (if applicable).
