The National Institutes of Health (NIH), through the National Cancer Institute (NCI), has announced a funding opportunity titled "Integrating Biospecimen Science Approaches into Clinical Assay Development" (FON: PAR-25-325). This initiative aims to support extramural research focused on addressing preanalytical variability in the development and analytical validation of clinical assays utilizing biospecimens such as tumor biopsies and liquid biopsies. The program seeks to enhance the reliability of biomarker assays by investigating how various collection, processing, and storage conditions impact biomarker quantification, ultimately contributing to improved cancer diagnostics and treatment in precision medicine. Interested applicants can apply for funding of up to $250,000 annually for a period of five years, with the first application deadline set for January 4, 2025.
