Biodesix to Present New Data on the Nodify XL2® Test at ATS 2024 Annual Meeting

05/21/2024

Data highlights ability of the Nodify XL2 test to identify benign nodules in patients with emphysema

Biodesix, Inc. (Nasdaq: BDSX), a leading diagnostic solutions company with a focus in lung disease, announced that new data will be presented today at the 2024 American Thoracic Society (ATS) International Conference in San Diego, California. The presentation, titled "Performance comparison of a blood-based integrated classifier for lung nodule risk stratification in patients with versus without emphysema," will be presented by Arthur Romero MD, MSC, FCCP, Associate Professor of Pulmonary and Critical Care Medicine at the University of Nevada Las Vegas.

Emphysema is a common comorbid pulmonary condition in patients with lung nodules and presents unique diagnostic and treatment challenges. The presentation will review a subgroup analysis of 280 patients enrolled in the prospective, real-world ORACLE study (NCT03766958), demonstrating that the Nodify XL2 test has high negative predictive value, or true negative rate, in patients with and without emphysema. These results suggest that the test can assist with ruling out lung cancer regardless of a patient’s emphysema status.

"During the course of emphysema treatment, many of our patients present with suspicious lung nodules," said Dr. Romero. “Until we are confident that the lung nodule is benign, we cannot proceed with certain emphysema treatments capable of improving quality of life. Some nodules need to be followed for up to two years to establish stability, but many patients cannot wait this long. Using the Nodify XL2 test in these patients may help us avoid unnecessary diagnostic procedures and delays, allowing us to safely proceed with needed emphysema treatments.”
