• Data demonstrates a 51% relative increase in the proportion of lung nodule biopsies diagnosing cancer

BOULDER, Colo. / Aug 22, 2023 / Business Wire / Biodesix, Inc. (Nasdaq: BDSX), a leading data-driven diagnostic solutions company with a focus in lung disease, announced today that a new analysis from the post-market, prospective, real-world ORACLE study (An Observational Registry Study to Evaluate the Performance of the Nodify XL2 Test NCT03766958) will be presented at the 6^th Annual Conference of the American Association for Bronchology and Interventional Pulmonology (AABIP). The data will be presented by principal investigator of the ORACLE study, Michael Pritchett, DO, MPH, on Thursday, Aug. 24, 2023 in a live poster presentation in Chicago, IL.

The Nodify XL2 test is designed to identify likely benign lung nodules that can be monitored with computed tomography (CT) scans instead of costly invasive procedures. The primary endpoint of the ORACLE study demonstrated that patients with benign lung nodules managed with the test were 74% less likely to undergo an unnecessary invasive procedure compared to the control group. Additionally, the proportion of patients sent to CT surveillance with malignant nodules did not differ between the Nodify XL2 group and the control group.

The analysis to be presented at AABIP investigated the effect of improved identification of benign lung nodules on the remaining patients who received a diagnostic biopsy. Prior to implementation of the Nodify XL2 test, 49% of patients receiving a biopsy had a lung cancer diagnosis compared to 74% when the test was used in clinical decision making, representing a 51% relative increase in the cancer diagnosis rate.

“Finding a suspicious lung nodule can create fear and anxiety for patients, whether it is found through lung cancer screening or an incidental finding from imaging for general medical purposes,” said Dr. Pritchett. “It is very encouraging that the Nodify XL2 test is helping physicians avoid unnecessary invasive procedures on benign lung nodules and prioritize patients with a higher risk of lung cancer. These results offer peace of mind to both patients and providers as they navigate the diagnostic plan.”
