Measuring What Matters: Biomarkers, Imaging, and Statistical Rigor with Guest David Raunig

With more than two decades of experience at the intersection of biostatistics and biomedical imaging, Bracken Senior Partner Dr. David Raunig has been a driving force in biomarker development, validation, and regulatory strategy. From leading FDA biomarker qualification review teams to co-inventing imaging advancements and setting industry-wide standards through QIBA, David has played a pivotal role in defining how we measure—and trust—biological data in clinical trials.

In this episode of Fractals: Life Science Conversations, David and host Colin Miller explore:

• What truly defines a biomarker—and how clinical outcome assessments differ from biological markers.
• Why the FDA’s "context of use" is key to biomarker qualification and how to demonstrate that a biomarker measures what it’s meant to. 
• How the evolution of imaging—from WHO criteria to RECIST to AI-assisted reads—could transform how we assess tumor burden and therapeutic response. 
• Statistical strategies for trial design and endpoint validation, and why QIBA’s standardized imaging protocols are essential tools for trial sponsors.
