Qiagen acquired AdnaGen’s circulating tumor cell (CTC) enrichment technology to boost its capabilities in liquid biopsies. Separately, the company formed a partnership with Tokai Pharmaceuticals to combine its new CTC technology with a molecular assay to co-develop and commercialize a companion diagnostic for Tokai’s galeterone, which is in late-stage clinical trials for treatment of castration-resistant prostate cancer (CRPC). The noninvasive 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, according to Qiagen officials.
