Precision Pathology – challenges and innovations in tissue biomarker analysis for diagnosis
Duration 58 min
About the webinar

Companion diagnostic biomarkers have become critical gatekeepers to the development and prescription of new personalized drugs. They are required for patient stratification in clinical trials, regulatory approval, market access of drugs, and treatment selection once the drug is approved. The increasing demand for tissue diagnostics offers multidimensional and spatially resolved information to understand better and score the tumor microenvironment and immune landscape. Existing examples of tissue biomarkers used in current routine diagnostics for breast cancer or immune therapy are part of standard protocols for treatment selection. Still, several challenges related to a lack of standardization and high variation in the tissue samples’ preparation and interpretation must be mitigated.

Part one:

In the first part of this seminar, Dirk Vossen, Chief Diagnostics Officer and Head of Product, will discuss the types and magnitude of these challenges and potential solutions in precision pathology using digital image analysis based on artificial intelligence. Some of these solutions are tested and proven, while others are in the proof-of-concept stage. With this overview, Dirk will demonstrate and recommend a path forward for mitigating current limitations in using clinical IHC assays.

Part two:

In the second part of the seminar, Esther Abels, Chief Clinical and Regulatory Officer, will discuss the regulatory pathways for digital and precision pathology. She will explore what drives the regulatory pathway, how clinical adoption barriers in digital pathology could be overcome, and the current regulatory landscape in the digital pathology field.

Presented at USCAP 2021 on March 17th.
