Fatty acid synthase (FASN), an enzyme that drives de novo lipogenesis, plays a relevant role in metabolic disorders such as obesity, non-alcoholic fatty liver disease (NAFLD) or type 2 diabetes. Denifanstat (TVB-2640), a FASN inhibitor, has recently shown positive results in a phase II study in patients with metabolic dysfunction-associated steatohepatitis (MASH).
