초록
Metabolic dysfunction-associated steatotic liver disease, formerly referred to as non-alcoholic fatty liver disease, is the most common liver disease in Western countries and has emerged as the leading indication for liver transplantation. Metabolic dysfunction-associated steatohepatitis (MASH), a more advanced stage, carries a high risk of progression to liver fibrosis, cirrhosis, liver failure, and hepatocellular carcinoma. Until recently, lifestyle intervention remained the mainstay of MASH management, with no pharmacological treatments specifically approved. However, advances in understanding its pathophysiological mechanisms have fueled numerous clinical trials, culminating in the Food and Drug Administration’s (FDA) approval of resmetirom as the first treatment for MASH in 2024. Additionally, many investigational drugs are nearing FDA approval or progressing through late-stage clinical trials. This review examines the current therapeutic landscape, highlights strategies for identifying patients suitable for liver-directed therapies in real-world settings, and discusses the challenges that remain.
