GENFIT Announces Publication in Nature Medicine Confirming the Performance of its NASH Diagnostic Technology  

Lille (France); Cambridge (Massachusetts, United States); Zurich (Switzerland); September 26, 2023GENFIT (Nasdaq and Euronext: GNFT), a late-stage biopharmaceutical company dedicated to improving the lives of patients with rare and severe liver diseases, today announced the publication of data demonstrating the effectiveness of its non-alcoholic steatohepatitis (NASH)1 diagnostic technology NIS4® by the FNIH’s2 NIMBLE3 project in the scientific journal, Nature Medicine4.

NIMBLE, part of the FNIH Biomarkers Consortium, is a public-private partnership that brings together U.S. government agencies, academic researchers and industry partners to study the diagnostic performance of non-invasive biomarkers to assess liver disease. The recent study evaluated five blood-based panels5, which included NIS4®, NIS2+™’s predecessor.

The study aims to confirm the diagnostic performances of existing biomarker panels and determine their advantage over commonly used laboratory tests (ALT and FIB-4). Such studies conducted provide necessary data for the regulatory approval of biomarkers for the diagnosis of at-risk NASH and is a crucial step in moving the field closer to having qualified Non-Invasive Tests, such as NIS4® or now NIS2+™, that can be used for widespread clinical use.

The findings, published in the scientific journal Nature Medicine, concluded that NIS4® achieved an AUROC6 of 0.815 for its intended use of diagnosing at-risk NASH, demonstrating significant superiority over common clinical-laboratory tools. It also confirmed that NIS4® was the only panel efficient for the diagnosis of the composite phenotype of at-risk NASH. Regarding the detection of NASH and significant fibrosis (F≥2) independently, NIS4®’s performance was superior to the other biomarker panels tested, achieving AUROC values of 0.832 and 0.874, respectively.

These findings represent an important milestone in NIS4® technology’s path to regulatory approval by the U.S Food and Drug Administration. NIS2+™, the newly published and optimized version of NIS4®, is currently in the process of being independently evaluated through the NIMBLE consortium.

Arun J Sanyal, M.D., Director of the Stravitz-Sanyal Institute for Liver Disease and Metabolic Health at Virginia Commonwealth University and Chair of the NIMBLE Consortium, commented: “Such findings will bring us a step closer towards a fully approved biomarker panel which can be made available for widespread clinical use and potentially alleviate the major barrier to care and drug development access. NIS4®’s utility as an effective technology to diagnose at-risk NASH is clearly demonstrated in these findings and we look forward to evaluating NIS4®’s more advanced version, NIS2+, in the near future.”


NIS2+™ is a blood-based diagnostic technology specifically designed to detect at-risk NASH among patients with metabolic risk factors based on an independent 2-biomarker panel. It is an optimization of the NIS4® technology and was developed and validated by GENFIT as a robust technology across characteristics of interest such as type-2 diabetes, age and sex, allowing large-scale implementation in clinical practice. GENFIT continues to explore the possibility of obtaining regulatory approval and CE Certificates of Conformity, with a development and commercial partner, to release an IVD test powered by NIS2+™ technology on the US and European markets.

NIS4® technology, NIS2+™’s predecessor, is being commercialized by Labcorp in the US and Canada as a Laboratory Developed Test. Since May 2021, Labcorp has been commercializing NASHnext®, powered by NIS4® technology, for use in the clinic. For more information, visit:

GENFIT is a late-stage biopharmaceutical company dedicated to improving the lives of patients with rare and severe liver diseases characterized by high unmet medical needs. GENFIT is a pioneer in liver disease research and development with a rich history and strong scientific heritage spanning more than two decades. Its capacity to develop high potential assets, from early-stages to late development and pre-commercialization stages, is illustrated through the successful 52-week readout of its Phase 3 trial (ELATIVE®) evaluating elafibranor in Primary Biliary Cholangitis (PBC). Today, GENFIT has a diversified R&D pipeline covering several therapeutic areas: five programs in acute on chronic liver failure (ACLF) are in clinical stages (Phase 2) and pre-clinical stages, including hepatic encephalopathy (HE), one of the main complications of ACLF; a Phase 2 clinical program targeting cholangiocarcinoma; and a preclinical program targeting urea cycle disorders (UCD) and organic acidemias (OA). GENFIT’s pipeline also includes a diagnostic franchise focused on Metabolic dysfunction-associated steatohepatitis (MASH, formerly known as nonalcoholic steatohepatitis or NASH) and ammonia. GENFIT has facilities in Lille and Paris (France), Zurich (Switzerland) and Cambridge, MA (USA). GENFIT is a publicly traded company listed on the Nasdaq Global Select Market and on compartment B of Euronext’s regulated market in Paris (Nasdaq and Euronext: GNFT). In 2021, IPSEN became one of GENFIT’s largest shareholders and holds 8% of the company’s share capital. For more information, visit
