Study summary

This study is a multicenter retrospective chart review. Sites with at least 100 patients tested with the IC and AAT tests, who have index dates (date of IC and AAT testing) at least one year prior to data collection date will be eligible for participation.

Read the detailed description

This study is a multicenter retrospective chart review. Sites with at least 100 patients tested with the IC and AAT tests, who have index dates (date of IC and AAT testing) at least one year prior to data collection date will be eligible for participation.

The protocol will require institutional IRB approval and a waiver of patient consent will be obtained. The data to be collected will be de-identified when entered into the study database. The collection of this de-identified data does not pose any risk to the subjects and does not require any further testing of the patient. The chart review will utilize a third-party Clinical Research Associate (CRA) with certified ICH-GCP training for data collection and documentation. Biodesix, Inc. in conjunction with the CRA will develop and maintain the Electronic Data Capture (EDC) system.

What researchers measure

Primary outcomes

  1. Assess Test Performance of AAT test

    To assess the performance of the AAT test in a real-world patient population: 1. Sensitivity of the AAT test at 24 months 2. Specificity of the AAT test at 24 months 3. Positivity predictive value of the AAT test at 24 months

    Time frame: Up to 24 months

  2. Assess Test Performance of IC test

    To assess the performance of the IC test in a real-world population: 1. Sensitivity of the IC test at 24 months 2. Specificity of the IC test at 24 months 3. Negative predictive value of the IC test at 24 months

    Time frame: 24 months

  3. Assess serial performance of serial testing with the AAC and IC tests.

    Assess the performance of the of serial testing with the AAC and IC tests

    Time frame: 24 months

Secondary outcomes

  1. Assess ATT Test Accuracy

    To assess the accuracy of the AAT post-test risk of malignancy by comparing with the actual patient outcome. * Compare the AAT test predicted proportion of malignant nodules to the actual proportion of malignant nodules by probability decile. * Compare the IC test predicted proportion of malignant nodules to the actual proportion of malignant nodules by probability decile.

    Time frame: Up to 24 months

  2. Determine Health Outcomes

    To determine one-year health outcomes of patients stratified by AAT and IC tests result risk categories. * The number and type of invasive diagnostic procedure performed on newly identified nodules stratified by AAT test results. * The number of patients routed to CT surveillance following initial nodule evaluation that result in nodule resolution or up to 24-month radiographic stability stratified by the AAT test. * The number and type of invasive diagnostic procedures performed on newly identified nodules stratified by IC test results. * The number of patients routed to CT surveillance following initial nodule evaluation that result in nodule resolution or up to 24-month radiographic stability stratified by the IC test. * The number of malignant nodules identified following a diagnostic procedure stratified by histology and stage. * The number of specific benign nodules identified following a diagnostic procedure, stratified by pathological findings.

    Time frame: Up to 24 months

Other outcomes

  1. Assess Test Performance in Sub-Populations

    Assess the performance of the AAT and IC tests in patient subpopulations. 1. Sensitivity of the AAT test in patient sub-populations at 24 months 2. Specificity of the AAT test in patient sub-populations at 24 months 3. Positivity predictive value of the AAT in patient sub-populations test at 24 months 4. Sensitivity of the IC test in patient sub-populations at 24 months 5. Specificity of the IC test in patient sub-populations at 24 months 6. Negative predictive value of the IC test in patient sub-populations at 24 months

    Time frame: Up to 24 months

  2. Assess Test Performance in Populations Outside of Validation

    To assess the performance of the AAT and IC tests in populations outside of their primary validated populations. 1. Sensitivity of the AAT test in patient sub-populations at 24 months 2. Specificity of the AAT test in patient sub-populations at 24 months 3. Positivity predictive value of the AAT in patient sub-populations test at 24 months 4. Sensitivity of the IC test in patient sub-populations at 24 months 5. Specificity of the IC test in patient sub-populations at 24 months 6. Negative predictive value of the IC test in patient sub-populations at 24 months

    Time frame: Up to 24 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 7, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
