Silymarin for the Treatment of Non-Alcoholic Fatty Liver Disease (NAFLD)

Phase 2

Completed

• Conditions: Non-alcoholic Fatty Liver Disease
• Interventions: Drug: Sillymarin; Drug: Placebo

• Registration Number: NCT02006498
• Lead Sponsor: University of Malaya

Brief Summary

This is a randomised study to examine whether high dose Sillymarin will be able to help improve fat-induced liver damage in the liver. The study hypothesis is that high dose Sillymarin will be able to reduce steato-hepatitis (fat-related liver inflammation) better than placebo.

Detailed Description

OBJECTIVES OF STUDY Primary Objectives

1. To assess the safety and adverse event profile of Silymarin compared to placebo.

2. To assess the efficacy of Silymarin as defined by an improvement in non-alcoholic steatosis (NAS) activity score by at least 30% from baseline compared to placebo.

Secondary Objectives

1. To compare NAS activity before and after Silymarin therapy.

2. To characterize changes in ALT and AST during Silymarin therapy.

3. To compare insulin resistance measured by HOMAr during Silymarin therapy.

Exclusion Criteria

• Use of silymarin or other milk thistle preparations for a period of 90 consecutive days or longer between biopsy and initial screening, or within 30 days prior to screening if the biopsy is performed during the screening period.
