On-Q-ity Inc.

Formed by the 2009 merger of CELLective DX and DNA Repair Co., On-Q-ity Inc. is developing personalized molecular diagnostics for cancer. The start-up thinks that combining DNA repair biomarkers with its ability to capture and analyze circulating tumor cells provides a complete view of an individual patient's pending treatment options and allows for more patient-friendly monitoring of the treatment's progress. On-Q-ity is currently conducting large-scale trials analyzing the response of DNA repair mechanisms to breast cancer therapies, focusing particularly on the anthracycline class of drugs. Initial studies are based on tissue samples, but the company will begin trials with circulating tumor cells in various cancers later this year.
