Trial Information

Different Strategies Using Autoantibodies and/or CT Scan Detection of Lung Cancer

In this trial, the addition of a blood biomarker test is being combined with early LDCT to
determine if screening with combination may result in detection of more lung cancer at an
earlier stage of disease.The study will also assess if the blood test is able to detect lung
cancers in high risk individuals when the LDCT is negative for cancer. There will be
health-economic costs included in the final analysis of study data.

Inclusion Criteria:

- Smokers or former smokers

- At least 20 pack year history of smoking

- Ages 50 - 75

Exclusion Criteria:

- Had a CT scan of chest within last 24 months

- History of any cancer within 10 yrs (except skin cancer or cervical cancer)

- A serious illness that decreases life expectancy to less than 5 years

- Any current use of Oxygen

- Uncontrolled congestive heart failure or cardiac arrhythmia that would prevent
surgery for a lung lesion

- Severe COPD or dyspnea that would prevent lung surgery or stereotactic body

Type of Study:


Study Design:

Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Screening

Outcome Measure:

CT alone vs. both Early CDT-Lung test and CT scan.

Outcome Description:

Assess the number of lung cancers detected with CT alone vs. with both Early CDT-Lung test and CT scan. Compare positive CT results with positive/negative Early CDT Lung test results and assess ability of the combination to detect earlier stage lung cancer.

Outcome Time Frame:

One year
