Clinical Trial Data
The American BioOptics team has performed both animal and human clinical trials with a primary focus on colon cancer. Published trials to date include a pilot study involving 63 average risk patients undergoing screening colonoscopy at Evanston Northwestern Healthcare, as well as animal trials on rats and mice.
These early results are remarkable, when compared to clinically available FOBT and fecal DNA analyses, which have sensitivities of 10.8% and 18.2%, respectively. Ongoing trials are actively improving upon these initial results.
Both the animal and human clinical trials show the ability of optical technology to predict cancer risk well before the earliest observable changes in the cells’ histology. In addition, results of the human trials showed, for the first time, the ability of ABO’s optical technology to predict risk of advanced polyps throughout the colon in both experimental colorectal cancer models and humans.
