GENFIT presents new NIS4® data in NASH at the International Liver Congress™ and the 81st Scientific Sessions of the American Diabetes Association

Study highlights the clinical performance of NIS4® technology in diagnosing at-risk NASH in patients with type 2 diabetes irrespective of age compared to other non-invasive testsNew analyses show the potential of NIS4® technology to be a valuable clinical tool either alone or in sequential combination with other blood-based non-invasive tests in identifying at-risk NASH and advanced fibrosis in patients with and without type 2 diabetes  Key Opinion Leaders highlight the potential for non-invasive tests in the diagnosis of at-risk NASH on ADA TV Lille, France; Cambridge, MA; June 23, 2021 – GENFIT (Nasdaq and Euronext: GNFT), a late-stage biopharmaceutical company dedicated to improving the lives of patients with metabolic and liver diseases, today announced it will be making two poster presentations at two internationally-renown scientific and medical events in June 2021, including a thought-leadership documentary featuring Key Opinion Leaders (KOLs). A poster presentation looking at the effects of age on the clinical performance of GENFIT’s proprietary diagnostic technology NIS4® in diagnosing at-risk NASH in patients with type 2 diabetes in comparison to a number of non-invasive tests, will be presented at the International Liver Congress™ 2021 on June 23-26, 2021, organized by the European Association for the Study of the Liver (EASL). A poster presentation providing key insights into the performance of NIS4® technology either alone or in combination with other blood-based non-invasive tests in identifying at-risk NASH and advanced fibrosis in patients with and without type 2 diabetes, will be presented at the 81st Scientific Sessions of the American Diabetes Association (ADA) on June 25-29, 2021. In addition, GENFIT is a key contributor to a thought-leadership documentary for ADA TV discussing, alongside KOLs, the link between NASH and patients with type 2 diabetes and how access to non-invasive diagnostic test kits to diagnose NASH, such as NASHnext™, powered by GENFIT’s NIS4® technology, could provide an alternative to costly and invasive procedures and potentially benefit millions of patients. Featured KOLs include: Dr. Fernando Bril, Endocrinologist, University Alabama-Birmingham School of Medicine (Birmingham, Alabama)Dr. Stephen Harrison, Gastroenterologist/Hepatologist, Medical Director at Pinnacle Research (San Antonio, Texas)Dr. Suneil Hosmane, GENFIT (Cambridge, Massachusetts)Dr. Brian Cavaney, CMO, Labcorp (Burlington, North Carolina)Donna Cryer, President and Founder of the Global Liver Institute (Washington, DC) To view the 5-minute thought-leadership documentary, please click on the following link: https://www.youtube.com/watch?v=MlBoAG5tFMEv Both events will be held virtually and the full programs can be found on the American Diabetes Association website and on the International Liver Congress™ website. POSTER PRESENTATIONS International Liver Congress™ June 23-26, 2021 Title: In Type 2 Diabetic Patients, the Identification of At-risk Nash is Impacted by Age: A Comparison of Serum-Based NITS Including NIS4® Abstract number: 2739 Poster identifier: PO-2739 Authors: Vlad Ratziu, Jeremy Magnanensi, Sylvie Deledicque, Elodie Delecroix, Yacine Hajji, Christian Rosenquist, Suneil Hosmane and Arun Sanyal. 81st Scientific Sessions of the ADA Title: Application of NIS4® Technology for Stand-alone and Sequential Identification of At-risk NASH or Advanced Fibrosis in Non-Diabetic and Type 2 Diabetic Patients Abstract number: #2021-A-5594-Diabetes Poster number: 1174-P (Category 21-C Integrated Physiology—Liver) Authors: Christian Rosenquist, Yacine Hajji, Jérémy Magnanensi, Nicolas Stankovic-Valentin, Suneil Hosmane and Arun J. Sanyal ABOUT THE INTERNATIONAL LIVER CONGRESS™ The International Liver Congress™ is an annual congress and EASL’s flagship event, attracting scientific and medical experts from around the world to learn about the latest in liver research. ABOUT THE ADA The ADA is the US’ leading voluntary health organization fighting to bend the curve on the diabetes epidemic and help people living with diabetes thrive. It holds annual scientific sessions to bring together the latest, cutting-edge advances in diabetes research, prevention and care. ABOUT NIS4® NIS4® is GENFIT’s non-invasive, blood-based diagnostic technology, which was developed to identify patients with non-alcoholic steatohepatitis (NASH) and significant to advanced fibrosis (F>2), also referred to as at-risk NASH. In January 2019, GENFIT signed a licensing agreement with Labcorp® to make NIS4® technology available for use in clinical research through their drug development subsidiary, Covance. In September 2020, GENFIT signed another licensing agreement with Labcorp to commercialize NIS4® in the US and Canada as a Laboratory Developed Test. Since April 2021, Labcorp has made NASHnext™, powered by NIS4®, available for use in the clinic. GENFIT also continues to explore opportunities to obtain formal marketing authorization of an in vitro diagnostic (IVD) test supported by NIS4® technology in both the U.S. and European markets.

ABOUT NASH NASH is a liver disease characterized by an accumulation of fat (lipid droplets), along with inflammation and degeneration of hepatocytes. The disease is associated with an increased risk of cardiovascular disease along with long-term risk for progression to cirrhosis, leading to liver insufficiency and potential progression to liver cancer. NASH is a serious disease that often carries no symptoms in its early stages, but if left untreated can result in cirrhosis, cancer, and the need for liver transplant. The prevalence of NASH is rapidly increasing as a result of the growing obesity and diabetes epidemics and is believed to affect as much as 12 percent of people in the U.S. and six percent worldwide.
