Roche granted FDA Breakthrough Device Designation for first AI-driven companion diagnostic for non-small cell lung cancer

• The VENTANA TROP2 (EPR20043) RxDx Device is an immunohistochemistry (IHC) assay combined with a digital pathology algorithm to determine patient treatment. 
• The device uses artificial intelligence–based image analysis with a level of diagnostic precision not possible with traditional manual scoring methods. 
• This Breakthrough Device Designation (BDD) demonstrates Roche’s continued innovation in companion diagnostics and digital pathology to enable more precise diagnosis in oncology.

BASEL, April 29, 2025 – Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that the U.S. Food and Drug Administration (FDA) granted Breakthrough Device Designation for the VENTANA® TROP2 (EPR20043) RxDx Device. This is the first Breakthrough Device Designation to be granted for a computational pathology companion diagnostic (CDx) device.

The VENTANA TROP2 (EPR20043) RxDx Device is a computational pathology device, consisting of the TROP2 algorithm, navify® Digital Pathology Image Management System, Roche Digital Pathology scanners (DP 200, DP 600) and the VENTANA TROP2 (EPR20043) RxDx Assay used with OptiView DAB Detection Kit for staining on a BenchMark ULTRA IHC/ISH staining instrument. The VENTANA TROP2 (EPR20043) RxDx Device analyzes whole-slide images of non-small cell lung cancer (NSCLC) tissue stained with TROP2 to compute a quantitative TROP2 score.

The algorithm incorporates AstraZeneca’s proprietary computational pathology platform, Quantitative Continuous Scoring (QCS), which enables a level of diagnostic precision not possible with traditional manual scoring methods.

The FDA granting Breakthrough Device Designation has the potential to make a TROP2 CDx AI-driven system available sooner, which could aid in identifying patients with NSCLC most likely to benefit from treatment with Daiichi Sankyo and AstraZeneca’s DATROWAY® (datopotamab deruxtecan-dlnk). DATROWAY is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed by AstraZeneca and Daiichi Sankyo.

About the VENTANA TROP2 (EPR20043) RxDx Device

The VENTANA TROP2 (EPR20043) RxDx Device is indicated as an aid in identifying patients with previously treated advanced or metastatic non-squamous NSCLC without actionable genomic alteration (AGA) most likely to benefit from treatment with Daiichi Sanko and AstraZeneca’s DATROWAY (datopotamab deruxtecan-dlnk). A qualified pathologist is responsible for reviewing staining and image quality, as well as ensuring adequate tumor detection sensitivity and precision, in conjunction with histological examination, relevant clinical information and proper controls.

Following the pathologist assessment, the nDP TROP2 algorithm independently detects tumor cells and generates associated measures of TROP2 IHC staining intensity in both membrane and cytoplasm to compute the Normalised Membrane Ratio (NMR) score. The algorithm then classifies the TROP2 status as positive or negative based upon the pre-defined NMR cutoff.
