Precision Gene Testing to Reduce Over-Treatment in HER2-Positive Breast Cancer

healthPilotedTRL 8

Imagine giving a patient a powerful medicine that works but has harsh side effects they don't actually need. This project uses a 27-gene test to figure out who can safely skip the most aggressive treatments. It's like a personalized map that tells doctors exactly how much medicine is enough to cure the cancer without overdoing it.

The business problem

What needed solving

Many breast cancer patients undergo aggressive, toxic, and expensive treatments that are not necessary for their specific tumor profile. There is currently no widely adopted diagnostic test to safely guide the reduction of these therapies.

The solution

What was built

A validated 27-gene expression test (HER2DX) and a multi-center clinical trial protocol to prove its effectiveness in reducing treatment toxicity and costs.

Who can put this to work

Precision Diagnostics
SME
Target: Genomics Laboratory

If you are a genomics laboratory dealing with a lack of validated tools for breast cancer therapy guidance — this project developed the HER2DX test that identifies patients for treatment de-escalation. This allows for the commercial offering of a validated 27-gene expression test.

Healthcare Providers
mid-size
Target: Private Oncology Clinic

If you are a private oncology clinic dealing with high costs and patient toxicity from intensive therapies — this project developed a clinical validation for HER2DX that reduces direct and indirect costs. It helps maintain survival outcomes while improving patient quality of life.

Health Insurance
enterprise
Target: Medical Insurance Provider

If you are an insurance provider dealing with the high expense of unnecessary intensive chemotherapy — this project developed a way to prove that HER2DX reduces healthcare costs. By guiding treatment, it minimizes the payment for avoidable toxicities and hospitalizations.

Frequently asked

Quick answers

What is the cost or price of the HER2DX test?

Based on available project data, the specific price of the test is not mentioned, but the project aims to prove it reduces direct and indirect healthcare costs.

How is the test being scaled for industrial use?

The project is conducting a pragmatic clinical trial across 44 centres in 7 European and associated countries to validate the test for routine oncology practice.

What is the IP or licensing status of the 27-gene test?

Based on available project data, the test is already at TRL8, indicating it is a mature technology, though specific licensing terms are not provided.

What regulatory hurdles are currently being faced?

Regulatory approvals are pending in Ireland, Italy, France, and Germany due to discrepancies between national agencies, though documentation has been submitted.

What is the timeline for clinical validation?

The project runs from 2023-12-01 to 2028-11-30 to generate the necessary clinical evidence for adoption.

Consortium

Who built it

The consortium is highly diversified with 18 partners across 9 countries, blending academic research (5 universities, 7 research institutes) with industrial application (3 industry partners, including 1 SME). The 17% industry ratio suggests a strong push toward commercialization, supported by the inclusion of HTA and regulatory experts to ensure the diagnostic tool moves from the lab to the healthcare market.
