Development & Clinical Validation
Robust development and validation data
Ataraxis Breast RISK score was developed and validated using data from 8,161 breast cancer patients treated at 15 institutions in 7 countries.
The study included patients with all subtypes of early-stage and locally advanced invasive breast cancer, marking this as one of the most comprehensive evaluations of a prognostic/predictive test.

Over 50% improvement in accuracy compared to standard of care genomic tests
In validation of the Ataraxis Breast RISK score on three external cohorts from top international cancer centers, Ataraxis Breast reduced prediction error by approximately 50% compared to the standard of care genomic assays for hormone receptor-positive invasive breast cancer.
Works in all clinically relevant invasive breast cancer subgroups
Ataraxis Breast RISK was developed and validated on robust and diverse data from seven countries. The data included previously underserved groups, such as triple-negative breast cancer patients. Ataraxis Breast RISK was shown to be consistently prognostic across groups with various age, race, molecular and histological subtype, and nodal status.
