• Biomarker-Based Drug Development
Biomarker-based drug development is a systematic approach that drives the discovery, validation, and clinical application of novel therapeutics through the identification and utilization of specific biomarkers. Biomarkers are typically defined as molecules or characteristics that objectively indicate physiological or pathological states within the body—such as proteins, nucleic acids, and metabolites—which are commonly found in biological samples including blood, urine, and tissue. The primary objective....
