GENFIT Announces the Publication of New Data on the Clinical Performance of NIS2 ™ in Older Patients in Hepatology Communications

Lille (France); Cambridge (Massachusetts, United States); Zurich (Switzerland); August 10, 2023 - GENFIT (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 new data on the clinical performance of NIS2+™ in older patients, for the detection of at-risk nonalcoholic steatohepatitis (NASH) in Hepatology Communications¹.

In conjunction with Labcorp, a global leader of innovative and comprehensive laboratory services, data reported in the manuscript is the first to show and compare the clinical performance of NIS4® and its recently developed and improved upgrade NIS2+™ in a population of older adults (≥65 years of age) with well-established biomarker panels: FIB-4, NFS, ELF and ALT.

While previously published data showed that NIS2+™ had a high overall clinical performance for the detection of at-risk NASH achieving an AUROC² of 0.81 in a large study population, the Centers for Medicare & Medicaid Services (CMS) in the US requires peer-reviewed, published data showing that tests, that will be used for patient management, have high assay performance in patients who are ≥65 years of age. Results of this study showed the clinical performance of NIS2+™ was superior to other tests for the diagnosis of at-risk NASH in patients ≥65 years of age, greatly assisting with CMS reimbursement efforts. These data support the clinical value of this blood-based test for the diagnosis of at-risk NASH in older adults who would benefit from intensive lifestyle or therapeutic interventions.

Arun J Sanyal, MD, FAASLD, commented: “I am delighted to see this work published. At-risk NASH is a serious condition that is commonly present in those 65 years or older and can progress silently to cirrhosis. This study demonstrates that the NIS2+™ test can be used to identify this population, and provides clinicians a tool that can be used in primary care settings to identify patients with this condition, so that they can engage in more aggressive management strategies or triage them for tertiary care. Such simple, yet validated, tools are not widely available, and they represent an important addition to the diagnostic armamentarium for metabolic dysfunction-associated steatotic liver disease.”

ABOUT NIS2+™        

NIS2+™ is a blood-based diagnostic test specifically designed to detect at-risk NASH among patients with metabolic risk factors based on an independent 2-biomarker panel. It was developed and validated by GENFIT as a robust Non-Invasive Test (NIT) across characteristics of interest such as type-2 diabetes, age and sex, allowing large-scale implementation in clinical practice.
