Immuno-Oncology Is Making Pharma Step Up Its Diagnostics Game

Immuno-oncology has significant diagnostic needs including identifying patients most likely to respond to therapies. Current diagnostic approaches often fall short, due in large part to the complexity of the biology driving therapy responsiveness. As such, the biopharma industry is exploring many emerging approaches covering tumor, immune and even microbiome-related pathways and biomarkers.
