NASH-FITTER: Nonalcoholic Steatohepatitis Fitness Intervention Treatment Targeting Endothelial Dysfunction Reversal

Not Applicable

Withdrawn

• Conditions: Non-Alcoholic Fatty Liver Disease; NASH - Nonalcoholic Steatohepatitis; Non Alcoholic Steatohepatitis
• Interventions: Behavioral: Moderate intensity aerobic exercise

• Registration Number: NCT03864835
• Lead Sponsor: Milton S. Hershey Medical Center

Brief Summary

This research is being done to find out if aerobic exercise is beneficial in reversing scarring. Physical activity has been shown to increase fitness in healthy individuals as well as in those with NASH. This research will allow for better understanding the effects of physical activity on fitness and endothelial function in patients with NASH with the goal of reversing scarring.

Approximately 12 people will take part in this research study at Penn State (PSU) Milton S. Hershey Medical Center (HMC), Penn State Physical Medicine \& Research (PM\&R) Laboratories housed at the Hershey Center for Applied Research (HCAR) and the Penn State University Fitness Center (UFC).

Detailed Description

Preliminary studies show universally low cardiorespiratory fitness (CRF) in Nonalcoholic steatohepatitis (NASH) patients was dependent on body composition. The proposed work is based on the hypothesis that gains in cardiorespiratory fitness and improved endothelial function achieved through exercise can arrest or reverse progression of hepatic fibrosis, lessen cardiovascular disease risk (CVD), and improve all-cause mortality in patients with NASH. The aims of this research proposal are designed to characterize and better understand the effects of physical activity (PA) on CRF and endothelial function in patients with NASH. The goal is to arrest progression of fibrosis and reduce CVD risk. This proposal includes a cross-sectional study and a small pilot clinical trial in a high-risk subgroup of NASH most likely to benefit from PA.

Arm && Interventions

Group	Intervention	Description
Moderate intensity aerobic exercise	Moderate intensity aerobic exercise	All subjects will undergo DXA and CRF measurement (relative VO2max) under the supervision of an American College of Sports Medicine (ACSM)-certified fitness professional and study physician at the Penn State PM\&R Research Laboratories. Subjects selected for the interventional pilot trial will receive a FitBit Charge2 HR and be instructed on how to use a FitBit Hear Rate monitor, Fitbit application, Fitbit website, and Fitabase (secure data management platform utilized by \>400 clinical trials). Participants will record their daily food and beverage intake through the Fitbit app. Individualized feedback will be provided by a registered dietician (RD). Subjects that meet requirements for the exercise arm (12 total) will be required to exercise 30 minutes, five days per week at a moderate intensity (HR target corresponding to 45-55% of their relative VO2max). Each session will be supervised in-person at the Penn State University Fitness Center with an ACSM certified exercise physiologist.

Primary Outcome Measures

Name	Time	Method
hepatic fibrosis stage using METAVIR score	12 months	The primary endpoint of this study is change in hepatic fibrosis stage.

Secondary Outcome Measures

Name	Time	Method
flow mediated dilation	12 months	correlation between fibrosis change and improvements in FMD
NAFLD Activity Score (NAS)	12 months	The diagnosis of nonalcoholic steatohepatitis (NASH) is defined by the presence and pattern of specific histological abnormalities on liver biopsy. A separate system of scoring the features of nonalcoholic fatty liver disease (NA) called the NAFLD Activity Score (NAS) was developed as a tool to measure changes in NAFLD. The grading or NAFLD activity score (NAS) encompasses steatosis, lobular inflammation and ballooning.
intra-hepatic fat content	12 months	changes in intra-hepatic fat content
fibrosis change and gains in cardiorespiratory fitness	12 months	correlation between fibrosis change and gains in CRF
health related quality of life (HRQOL)	12 months	PROMIS is a computer adaptive test (CATs) used to assess health related quality of life. The survey contains profiles that measure multiple concepts through a fixed collection of short forms.
Body composition	12 months	body composition change
