Airway Epithelium Gene Expression in the Diagnosis of Lung Cancer: AEGIS II

Allegro Diagnostics is funding this multi-center study to validate and extend a new
diagnostic tool measuring global gene expression in airway epithelial cells obtained at
routine bronchoscopy in suspect lung cancer patients. The test, which is highly sensitive
and specific for lung cancer, measures the levels of expression of genes in cells brushed
from the large bronchi during diagnostic bronchoscopy. Similar brushings of epithelial
cells from the nose will be analyzed to determine if gene expression in these cells can be
used as a screening tool in subjects who may have now or be at risk for developing lung
cancer in the future.

Inclusion Criteria:

- Patients being evaluated for the diagnosis of possible lung cancer or "rule out lung
cancer" and undergoing clinically indicated bronchoscopy

- All patients are required to be at least 21 years of age and be able to understand
and sign the informed consent form

- Patient must be a current or former cigarette smoker

Exclusion Criteria:

- A pulmonary physician does not recommend that bronchoscopy be performed

- Inability to understand the written consent form and comply with requirements of the

- History of prior primary lung cancer

- Immediately prior to bronchoscopy, the patient has been on a mechanical ventilator
for >24 consecutive hours.

Type of Study:


Study Design:

Observational Model: Cohort, Time Perspective: Prospective

Outcome Measure:

Lung Cancer Diagnosis (positive or negative)

Outcome Description:

Patients may be followed at 12 months post bronchoscopy to finalize diagnosis if diagnosis had not previously been confirmed. The biomarker score will be compared to the standard diagnosis to evaluate the sensitivity, specificity, and negative predictive values of the biomarker.

Outcome Time Frame:

12 months
