The most frequent reason for a liver transplant is likely to be non-alcoholic steatohepatitis (NASH), which is expected to eventually overtake hepatitis C. There are no approved treatments for NASH at the moment. Together, these findings highlight the urgent requirement for developing practical solutions to reduce the burden of disease caused by NASH. NASH is a member of a spectrum of diseases that, in the majority of Western people, are strongly linked to obesity, insulin resistance, and the metabolic syndrome. Nearly 30% of the general population is thought to have excessive hepatic fat, and 2-4% may have NASH. The creation of primary preventive interventions should be a top public health priority due to this condition's high prevalence. Unfortunately, research targeting obesity as a risk factor for NASH have produced conflicting results. Although lifestyle changes are usually thought to improve statuses and insulin resistance, they are difficult for most people to maintain. Therefore, there is a critical need for effective pharmaceutical treatments that can reverse liver fibrosis and injury in NASH patients.
Regarding the creation of NASH medications, there are both good news and negative news. There are many molecular targets to reduce statuses, inflammation, cell death, and improve repair processes in affected people, according to a substantial body of basic science literature. However, the discipline is still in its infancy and is full with poorly planned experiments including numerous drugs and little usable data. According to drug development logic, it is essential to use drugs whose mechanisms of action are connected to disease pathogenesis, safety evaluation, selection of the best dose based on the therapeutic window, and a progression of clinical trials demonstrating proof of concept before demonstrating efficacy. Three excellent early phase studies that focus on three different pathways that further these goals have been published by CGH in this edition and the October issue. These enable one to begin identifying the agents most likely to be successful and eliminate the remainder from the list of available alternatives. However, it is important to consider the possible causes of the agent's failure despite a carefully designed clinical study before excluding a given molecule as a treatment for NASH. The use of all three of the investigated agents is supported by a compelling theoretical argument. Which regulates cyclic AMP, was the focus of the initial batch of investigations (cAMP).
Through modifying the activity of AMP kinase, a crucial regulator of metabolic balance, cAMP dampens the inflammatory response and has additional potential positive effects. However, it is theoretically conceivable that activation of protein kinase A, which may boost gluconeogenic drive, might have negated these advantageous effects. However, this was not formally assessed. Similarly, it has been demonstrated that resveratrol and fatty acid bile acid conjugates (FABACs) increase hepatic lipid mobilisation while enhancing insulin sensitivity and reducing de novo lipogenesis, respectively 8–10. The inadequacy of current preclinical models as substitutes for the human disease state may also be reflected by the failure of two of the three agents to show benefit, underscoring the necessity of developing more pertinent models and high throughput methods to screen molecules in the context of human disease for both efficacy and safety. inhibitor research (ASP9831) logically progressed from preclinical studies to a dose determination and safety trial to a proof of concept phase 2A study5. The sponsors and investigators should be commended for their thoroughness in reviewing this product as the trials were well powered and were not substantially different [1-5].
Despite being unfavourable, this study provides information on potential difficulties in NASH-related medication development. Early phase trials frequently concentrate on ALT improvement. However, there is an early drop in ALT regardless of treatment arm allocation in the first three months of entrance into the trial, as was clearly shown in the PIVENS and the TONIC trials. As a matter of fact, the trial using Aramchol used a change in hepatic steatosis as the primary endpoint and found that high dose test drug (100 mg) significantly reduced hepatic steatosis compared to place. It is uncertain if this discovery has any additional ramifications for future "go" or "no go" choices for further research. ALT levels fell as predicted in all three arms.
