About

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a leading cause of chronic liver disease worldwide and a significant public health issue. MASLD may progress to liver cirrhosis and/or hepatocellular carcinoma. Although previous evidence suggests that aspirin has antisteatotic and antifibrotic effects on the liver, a randomized controlled trial assessing long-term efficacy and safety of aspirin in MASLD patients has yet to be conducted. This study aims to conduct a randomized controlled trial to evaluate the efficacy of aspirin in treating MASLD.

Full description

Metabolic dysfunction-associated steatotic liver disease (MASLD) has become one of the most common chronic liver diseases, with an estimated prevalence exceeding 30% globally. MASLD can result in liver cirrhosis, hepatocellular carcinoma (HCC), and death, and it has become the leading cause of HCC waiting for liver transplantation in the U.S. Unfortunately, although several new drugs put forth in clinical trials have been shown to offer certain benefits towards improving MASLD, an effective medicine remains lacking. With the limitations in efficacy and safety issues, even though some medications maybe hopeful in the treatments for MASLD, more medical choices remain highly expected. Emerging laboratory evidence suggests that antiplatelet therapy, e.g., aspirin, can reduce the risk of MASLD progression; however, a well-designed clinical trial should be mandatory before its clinical use. A recently published 6-month, phase 2 randomized controlled trial (RCT) demonstrated that daily aspirin might improve MASLD, but several limitations of this study should be further investigated. Therefore, we aim to conduct a RCT to evaluate the long-term effect of low-dose aspirin therapy on MASLD. This phase 2, double-blind, randomized, placebo-controlled trial will recruit MASLD patients, who fulfill the inclusion and exclusion criteria of this study. Participants will be randomly assigned in a 1:1 ratio to receive daily low-dose (81mg) aspirin or a placebo for 240 weeks. Participants will be follow-up at outpatient clinics every 12 weeks, and liver stiffness measurement (LSM) will be evaluated by using vibration-controlled transient elastography (VCTE). The surrogate primary endpoint is mean absolute change of VCTE-estimated liver stiffness at week 48. The clinical- outcome primary endpoint is MASLD-related outcomes (LSM progression >= 5 kPa, liver decompensation, HCC development, cardiovascular events, and death) at week 240. The secondary endpoints include mean absolute changes of hepatic fat fraction measured by 1H-MR spectroscopy and liver function parameters and the cumulative incidence of bleeding events. Additionally, the study will explore associations between stool microbiota/ MASLD-related single nucleotide polymorphisms, such as PNPLA3, TM6SF2, MBOAT7 genes, and clinical outcomes.
