IRVINE, Calif. & AMSTERDAM--(BUSINESS WIRE)--Nov 4, 2025--

Agendia®, Inc., a leader in precision oncology for breast cancer, today announced it will present new results from the ongoing real-world FLEX Study (NCT03053193) at the 2025 San Antonio Breast Cancer Symposium (SABCS), taking place December 9-12 in San Antonio, Texas.

The company will present five posters, led by Agendia investigators and independent academic collaborators, that collectively highlight the broad clinical impact of MammaPrint ® + BluePrint ® genomic profiling in optimizing treatment decisions and improving outcomes for patients with hormone receptor positive, HER2-negative (HR+/HER2–) early breast cancer (EBC).

“We look forward to sharing these new findings from the FLEX Study, which spans more than 20,000 participants across 100 global sites, making it the largest and most diverse real-world evidence cohort for early-stage breast cancer,” said William Audeh, M.D., Chief Medical Officer at Agendia. “These results underscore our commitment to generating robust clinical evidence in settings beyond traditional clinical trials, ensuring the results can inform personalized treatment decisions across diverse patient populations and everyday clinical practice.”

The full list of abstracts & poster presentations is as follows:

About Agendia

Agendia is a global leader in precision oncology focused on early-stage breast cancer. The company’s genomic assays, MammaPrint + BluePrint, deliver essential biological insights to inform personalized treatment decisions for patients and their care teams. With operations in Amsterdam and Irvine, Agendia partners with academic and community oncology centers worldwide to generate real-world evidence through the landmark FLEX Study (NCT03053193), the largest whole-transcriptome registry of early-stage breast cancer.

About MammaPrint

MammaPrint is a clinically validated genomic test that analyzes the expression of 70 genes in breast cancer tissue to determine the likelihood of distant metastasis. By providing risk stratification into four categories — UltraLow Risk, Low Risk, High Risk 1, and High Risk 2 — MammaPrint enables more personalized, data-driven guidance to chemotherapy and endocrine therapy planning.

About BluePrint

BluePrint is a 80-gene molecular subtyping assay that reveals the underlying biology driving tumor growth, classifying tumors as Luminal-type, HER2-type, or Basal-type. By defining intrinsic subtypes beyond conventional pathology, BluePrint offers deeper biological understanding to refine therapeutic decision-making and enhance clinical outcomes.
