A Digital Solution for Individuals With Non Alcoholic Fatty Liver Disease

Sidekick Health has developed a digital behavioral change program (SK-241) specifically designed for people with metabolic derangements and non-alcoholic fatty liver disease (NAFLD). The SK-241 is delivered through a mobile application and aims at improving lifestyle and health outcomes by focusing on improving diet, increasing activity levels and reducing stress. In this study, the feasibility of the newly developed digital behavioral change program (SK-241) will be evaluated in a minimum of 30 individuals with a NAFLD diagnosis. The primary aim is to explore the acceptability of the SK-241 program by its users, in addition to exploring changes in clinical outcomes and medication adherence after a 12-week intervention with 6 months follow up.

Non-alcoholic fatty liver disease (NAFLD) is an umbrella term used to describe a spectrum of liver pathology, characterized by \>5% fat accumulation in the liver (steatosis), among people who drink little or no alcohol. Both genetic and lifestyle-related factors contribute to the pathogenesis of NAFLD. It is strongly associated with metabolic derangements, obesity, insulin resistance and type 2 diabetes mellitus. NAFLD is considered the liver manifestation of metabolic syndrome.

NAFLD can progress from a simple steatosis to a more severe and progressive condition, referred to as non-alcoholic steatohepatitis (NASH), which is characterized by additional liver inflammation and hepatocyte injury with or without fibrosis. In general, 20% of NAFLD patients are believed to progress to NASH.

Finding convenient and effective ways to incorporate lifestyle changes into daily lives of people with NAFLD and NASH is important. Sidekick Health has developed a digital behavioral change program (SK-241) for NAFLD and NASH patients consisting of an interactive mobile application.

The aim of this study is primarily to assess the acceptability and feasibility of adding a digital lifestyle intervention (SK-241) to the standard of care (SoC) for NAFLD patients, by assessing participants engagement, retention and satisfaction with the SK-241 program in a minimum of 30 individuals with a NAFLD diagnosis. In addition, the clinical effectiveness of the program will be explored. A minimum of 30 individuals with a NAFLD diagnosis will be included for a 12-week intervention with 6 months follow-up.
