Late-breaking clinical study results

presented at DIGESTIVE DISEASE WEEK (DDW) 2016


A new blood test for the detection of Colorectal Cancer (CRC)
Measurement of Natural Killer Cell Activity (NKA) in patients undergoing colonoscopy.



This study was conducted at Maisonneuve-Rosemont Hospital in Montreal, Quebec, Canada by Dr. Gilles Jobin and colleagues. 1047 successive subjects >40 years of age, who underwent colonoscopy, were recruited between October 2014 and January 2016. NK VueTM a novel in vitro diagnostic device (IVDD), was used to measure NKA in these subjects. NKA was compared in subjects with cancer-negative colonoscopies to those with pathologically confirmed CRC.

Preliminary study results will be presented for the first time at DDW 2016, May 21–24, 2016 by Dr. Gilles Jobin, Chief of Gastroenterology, Maisonneuve-Rosemont Hospital, Montreal, Quebec, during the Clinical Science Late-breaking poster session on Tuesday, May 24 starting at 9:30 a.m. in Hall C-SDCC (poster #Tu2088).*

The abstract has been published in the April 2016 supplement of Gastroenterology on page S-1270. Additional study details are available at Additional information on NK cells is available by visiting

NK Vue is the first commercially available IVDD that measures NKA in a small volume of stimulated whole blood. This IVDD was approved by Health Canada in December 2014 for the following indication: “NK Vue is intended for in vitro diagnostic use, for the monitoring of the immune status of individuals. Measurement of NK cell activity could be a useful tool for assessing changes in immunosurveillance, which, in turn, could be indicative of a condition or disease where NK cell activity has been shown to be affected.”



ATGen is a public immunodiagnostic company focused on the development of in vitro diagnostic devices for the analysis of patients’ immune function. Immunosurveillance performed by lymphoid cells is important in immunity against foreign antigens and tumor cells.
