Hyperuricemia Clinical Trial

Official title: Comparative Study Evaluating the Outcome of Febuxostat Versus Vitamin E in Hyperuricemia Patients With Non-alcoholic Steatohepatitis Without Cirrhosis

Status Recruiting

Clinical Trial Summary

This study aims at evaluating and comparing the protective outcomes of using Febuxostat versus Vitamin E in Hyperuricemia non-alcoholic steatohepatitis patients without cirrhosis. The intervention is 6-months duration and the study will assess the efficacy of either drug as fibrosis improvement (≥ 1 stage) with no worsening of NASH or NASH resolution with no worsening of fibrosis with the study considered successful if either 1ry end point is met. Also, assessment of biochemical markers related to steatosis, inflammation, oxidative stress, insulin resistance and liver fibrosis will be done.

Clinical Trial Description

Nonalcoholic fatty liver disease (NAFLD) is defined as the accumulation of excessive fat in the liver in the setting of no significant alcohol consumption and the absence of any secondary cause. NAFLD has reached epidemic proportions and currently affects 20-40% of the general population. In recent years, along with the increasing trend of obesity and type 2 diabetes, NAFLD has become one of the most common chronic liver diseases worldwide. The spectrum of the disease ranges from simple steatosis to hepatocellular injury with inflammatory infiltration characterized as nonalcoholic steatohepatitis (NASH) that may eventually progress to liver fibrosis, cirrhosis and hepatocellular carcinoma. Despite significant disease burden and mortality associated mainly with advanced disease, i.e., NASH and fibrosis, there is currently no approved medication for NASH, therefore, lifestyle modifications remain the mainstay of treatment. What is the pathogenesis of NAFLD? Although the proposal of "two hits" involving insulin resistance (IR) and oxidative stress has been well accepted, the mechanism of NAFLD was thought very complex and still remained unclearly. Besides metabolic syndrome-related conditions, hyperuricemia has also been linked to NASH. Several epidemiological studies have demonstrated that patients with NASH have significantly higher serum uric acid (UA) levels relative to controls, and elevated serum UA levels are an independent risk factor for NAFLD. Notably, UA itself has been reported to promote de novo lipogenesis and induce IR, both in vivo and in vitro, through increased NADPH oxidase (NOX)-mediated reactive oxygen species (ROS) generation and activation of the Nucleotide-binding and oligomerization domain (NOD-like) receptor family pyrin domain containing 3 (NLRP3) inflammasome. It is thought that hyperuricemia in NAFLD is primarily due to increased expression and/or activity of hepatic xanthine oxidase (XO). These observations indicate that hyperuricemia plays a causative role in the development of NASH. The xanthine oxidase (XO) inhibitor, febuxostat, decreases free fatty acids-induced fat accumulation in the liver of high-fat diet containing trans-fatty acids (HFDT) fed mice. It was further found that the underlying mechanism is related to the reduction in expression of NLRP3 and improved insulin resistance. This finding highlights the possible molecular pathways involving NLRP3 activation for management of ROS and IR. In conclusion, febuxostat may be a promising potential treatment for patients with NASH. It is acknowledged that vitamin E is the major lipid-soluble chain-breaking antioxidant found in the human body. In addition to its anti-oxidative properties, molecules of vitamin E family exert anti-atherogenic and anti-inflammatory activities. According to American Association for the Study of Liver Diseases (AASLD) and National Institute for Health and Care Excellence (NICE) guidelines, vitamin E is approved at a dose of 800 IU/day in adults with biopsy-proven NASH. Therefore, This study aims at evaluating and comparing the protective outcomes of using Febuxostat versus Vitamin E in hyperuricemic NASH patients without cirrhosis. The primary endpoint of this 6-months study would be fibrosis improvement (≥ 1 stage) with no worsening of NASH or NASH resolution with no worsening of fibrosis with the study considered successful if either 1ry end point is met. The secondary endpoint of this study is improvement of biochemical markers related to steatosis, inflammation, oxidative stress, insulin resistance and liver fibrosis. Study Population: - This study is conducted on 60 patients diagnosed with Hyperuricemic NASH according to the study protocol. - Patients has been recruited from Tropical Medicine and Infectious Diseases Department, Tanta University Hospital, Tanta, Egypt. - The study was approved by the Research Ethics Committee of Tanta University. - All patients have provided signed written informed consent and agreed to comply with the study protocol. - All data of the patients will be private and confidential. - Any unexpected risks appeared during the course of the research was cleared to the patients and the ethical committee on time. This study is randomized controlled, parallel and prospective 6-months duration study. Accepted patients was randomized into 2 groups as the following: - Group 1 (Febuxostat group): 30 patients will receive 80 mg/day febuxostat for 6 months. - Group 2 (Control group): 30 patients will receive Vitamin E 400 mg twice daily for 6 months. Any side effects will be reported and graded according to common terminology criteria for adverse events version 5.00 (CTCAE). Any potential drug interactions between administered drugs is monitored for each patient and corrective actions is taken. Statistical Analysis - All data will be represented as mean ± slandered deviation (SD). - Unpaired Student's t-test will be used to compare data between the two groups. - Paired Student's t-test will be used to compare data within the same group before and after treatment with the studied medications. - Chi-square test will be used for statistical analysis of nominal data. - The statistical analysis will be carried out using Statistical Package for the Social Sciences (SPSS) statistical package version 27.0 (December 2020), IBM (International Business Machines) corporation software group, USA. - The level of significance will be set at P< 0.05. ;
