QIAGEN acquires circulating tumor cell technology from AdnaGen QIAGEN (QGEN) announced an expansion of itsportfolio of liquid biopsies through the acquisition of an technology that enables enrichment and molecular analysis of circulating tumor cells from blood samples. The proprietary technology from AdnaGen allows a complete solution for the detection and analysis of CTCs for clinical applications. QIAGEN also announced a new partnership with Tokai Pharmaceuticals (TKAI) to combine this new CTC technology with a molecular assay to co-develop and commercialize a companion diagnostic for Tokai's novel drug compound galeterone, which is in late-stage clinical trials for treatment of castration-resistant prostate cancer. The non-invasive test will determine the expression of the AR-V7 biomarker, which in recent studies has demonstrated potential utility to guide therapy choice in CRPC patients. Financial terms for the AdnaGen acquisition and the Tokai partnership were not disclosed.
