The fibrogenic process, common to most forms of CLD, is driven by a complex interplay of cellular stress, inflammation, and wound-healing responses. Nicotinamide adenine dinucleotide phosphate oxidase isoforms 1 and 4 (NOX1 and NOX4) have emerged as key enzymatic sources of reactive oxygen species (ROS), serving as central mediators of hepatic oxidative stress, fibrogenesis, and inflammation. Setanaxib is a first-in-class, orally bioavailable, selective dual inhibitor of NOX1 and NOX4 that has progressed to clinical evaluation. This review synthesizes current knowledge on the molecular pharmacology of the NOX1/4 axis, preclinical evidence from translational models, and clinical trial outcomes to critically assess the therapeutic potential of targeted NOX inhibition in hepatic fibrosis. By attenuating hepatic stellate cell activation, modulating TGF-β signaling, reducing extracellular matrix (ECM) deposition, and regulating hepatic macrophage polarization, setanaxib exhibits pleiotropic antifibrotic effects. The compound also demonstrates favorable pharmacokinetic properties and a good safety profile in patients with PBC, with emerging evidence suggesting meaningful improvements in fatigue and quality of life. Finally, we examine the complex, and sometimes paradoxical, roles of NOX4 in liver pathophysiology, compare the evolving therapeutic landscape with other approaches such as farnesoid X receptor (FXR) agonists, and propose future paradigms integrating artificial intelligence–driven predictive modeling to optimize patient stratification and therapeutic response in this new era of redox-targeted hepatoprotective therapy.  \nKeywords: NADPH oxidase 1 (NOX4); reactive oxygen species (ROS); metabolic dysfunction steatotic-associated liver disease; primary biliary cholangitis  \n1. Introduction  \nChronic liver disease (CLD) remains a major global health burden, affecting over one-quarter of the world’s population and contributing substantially to morbidity and mortality [1] . Among the spectrum of CLD, metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as a leading cause. Regardless of etiology, hepatic fibrosis is  \nthe shared pathological outcome, resulting from sustained injury and dysregulated woundhealing processes. The excessive deposition of extracellular matrix (ECM) disrupts liver architecture, progressing to cirrhosis, liver failure, or hepatocellular carcinoma (HCC) [2] .  \nReactive oxygen species (ROS) are central mediators of fibrogenic signaling.
