Brief summary

The purpose of this study is to evaluate the dietary supplement Siliphos, which comes from milk thistle, to determine whether it is safe and well-tolerated in adults who have non-alcoholic steatohepatitis (NASH). An additional aim of this study is to determine whether Siliphos may be beneficial in treatment of NASH as indicated by improvement in liver enzymes (ALT and AST). The study hypothesis is that Siliphos will be safe and well-tolerated in people with NASH and will result in a decrease in the liver enzymes ALT and AST.

Detailed description

Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of liver conditions characterized by fat accumulation in the liver. Non-alcoholic steatohepatitis (NASH) is one form of NAFLD that may progress to cirrhosis in some people. Currently, there are no medications that are approved for the treatment of NASH. Milk thistle is sold over-the-counter as a dietary supplement. Milk thistle has been used for hundreds of years as a supplement to support liver function, and is commonly taken by people with a variety of liver conditions. Milk thistle may help to reduce inflammation and fibrosis (scar tissue) in the liver, so it may be beneficial in the treatment of NASH. As NAFLD is very common in the population, there are probably many people with NAFLD taking milk thistle supplements. However, there are no published studies of milk thistle in NAFLD. Therefore, this study is designed to provide preliminary evidence of the safety, tolerability, and efficacy of milk thistle in people with NASH. Comparison: The milk thistle supplement (called Siliphos) will be compared to a placebo (sugar pill) in this study.

Design outcomes

Primary

MeasureTime frameDescription
Number of Study Participants With Adverse Events6 weeksSide effect profile was collected at each study visit as tracked by study participants. Any new onset symptoms reported by study participants were recorded as side effects of treatment and analyzed according to whether they occurred while participants were treated with placebo or Siliphos. An increase in ALT value to greater than or equal to 2 x baseline value was also evaluated for possible drug induced liver injury.

Secondary

MeasureTime frameDescription
Number of Participants With a Decrease in ALT Value Greater Than or Equal to 15 U/L From Baseline to the End of the Treatment Era6 weeksChange in ALT value from baseline to end of treatment arm during the time treated with Placebo in comparison to the time treated with Siliphos. Significant change in ALT was defined as a decrease by 15 or more units from baseline to end of treatment period.

Recruitment details

Adults with biopsy-proven NASH were recruited from outpatient hepatology clinics. Liver biopsy had to be within the previous year (no liver biopsies were done specifically to enroll in the study). ALT was elevated (normal ALT defined as 30U/L for men and 20U/L for women) and other types of chronic liver disease (viral hepatitis, alcohol, autoimmune) evaluated and excluded. Baseline kidney function was also normal (creatinine less than or equal to 1).

Pre-assignment details

There were no participants who were excluded from study between informed consent/screening visit and study group allocation/randomization.

Outcome results

Primary

Number of Study Participants With Adverse Events

Side effect profile was collected at each study visit as tracked by study participants. Any new onset symptoms reported by study participants were recorded as side effects of treatment and analyzed according to whether they occurred while participants were treated with placebo or Siliphos. An increase in ALT value to greater than or equal to 2 x baseline value was also evaluated for possible drug induced liver injury.

Time frame: 6 weeks

Population: side effects and adverse events were gathered from study participants at each clinic visit
