¹ At EASL Congress in June 2023 it was announced that nonalcoholic steatohepatitis (NASH) would now be referred to as Metabolic dysfunction-associated steatohepatitis (MASH). Nonalcoholic fatty liver disease (NAFLD) will now be referred to as metabolic dysfunction-associated steatotic liver disease (MASLD). GENFIT is progressively transitioning its documentation over to this new nomenclature and both NASH and MASH terms may appear in our documents during this period.
