contact	BIOMARKER PANELS: OPTIMIZING DRUG TREATMENTS DNAR is validating and commercializing biomarker panels to guide optimal therapy decisions. These DNA Repair biomarkers reveal superior therapeutic opportunities for many currently approved cancer drugs that are only partially effective in the broader population. Also in development are DNAR biomarker panels to guide optimal patient selection and facilitate regulatory approval for new drugs in development. Biomarker panels can bring to light effective clinical applications for new drugs, helping patients get the most effective treatment, and speed the return on investment in drug development.
