Goal: To detect cancer at an early stage while providing additional therapies to more patients.
Cancer Moonshot

“…It is the proteins that comprise most of the biomarkers that are measured to detect cancers,
constitute the antigens that drive immune response and inter and intracellular communications,
and it is the proteins that are the drug targets for nearly every targeted therapy that is being
evaluated in cancer trials today.”
Conrads et al. 2016 Clinical Cancer Research

Objective: Determine analytical robustness and
reliability between laboratories
• Comparability of measurements between laboratories and define
critical parameters
• Ring trial participants adapt a system suitability test protocol to
maintain analytical performance
• Determine the range of accuracy and precision that users can
expect to achieve following the standardized product/assay
• The standardization enables the transfer of measurements
between laboratories

• Proteomics is being used to discover and establish the protein landscape of cancer cells or tissues
• Proteomic measurements complement genomics/transcriptomic measurements by reducing the vast number of potentially actionable somatic mutations and identifying genomic variances that might be actionable
