SHANGHAI, Nov. 13, 2021 /PRNewswire/ -- Wision A.I. Ltd, a startup in the field of artificial intelligence assisted diagnostics for gastrointestinal endoscopy, today announced it received the European CE Mark approval for EndoScreener, its AI-assisted polyp detection software during colonoscopy. It is the first CE Mark class II certificate under the new Medical Devices Regulation (MDR 2017/745).
Outstanding product performance and strong clinical evidence
Compared with previously self-declared class I devices for automatic polyp detection during colonoscopy[1], EndoScreener has an overwhelming advantage in terms of randomized controlled trial (RCT) clinical evidences. EndoScreener has demonstrated its efficacy in improving adenoma detection on more than 5000 patients in six rigorous randomized controlled trials, including three open RCTs[2], [3],one double-blinded RCTs[4] and two tandem colonoscopy RCTs[5], [6]. In the latest published multi-center tandem colonoscopy trial conducted at four U.S. leading academic medical institutions, EndoScreener reduced precancerous lesion (adenoma and SSL) miss rate by 41 % (19.13 vs 32.52 p=0.0047), and improved adenoma per colonoscopy (APC) by 33 % (0.9000 vs 1.1947 p=0.323 ). Even with high average adenoma detection rate (ADR) of 43.64% in screening/surveillance population under standard of care, no ceiling effect was found in this study.
Advanced AI technology in medical field enters the European market
Colorectal cancer (CRC) is a highly prevalent human malignancy, with over 1.9 million new cases and 935,000 deaths worldwide in 2020. It is also the second leading cancer killer in Europe, with one European dying of CRC every 3 minutes. Detection and removal of adenomatous polyps at early diagnosis and regular colonoscopy screening are the most effective ways to reduce the incidence and mortality of colorectal cancer. The opening of the European market for EndoScreener will eventually contribute to the prevention of colorectal cancer, saving resources in health services and reducing country expenditures. Wision A.I. is open for country-level collaborators to speed up making the solution generally available in different regions of the EU.
High compatibility and easy deployment
EndoScreener is a real-time computer-aided diagnosis software that assists endoscopists to provide a simultaneous visual notification and sound alarm for polyp detection during colonoscopy. As a software-only medical device (SaMD) with relatively economical total cost of ownership (TCO), EndoScreener is compatible with most mainstream endoscope systems With proper off-the-shelf computer hardware, the AI solution can be deployed with high flexibility in various clinical environments for colonoscopy
