About this study

Official title: Low Dose Thyroid Hormone, Mitochondrial Fatty Acid Oxidation, and Treatment of Nonalcoholic Steatohepatitis (NASH)

Nonalcoholic steatohepatitis (NASH) is the aggressive form of nonalcoholic fatty liver disease, which is rapidly becoming a worldwide public health problem. It is more common in the military and Veteran population compared to the general US population. NASH may progress to end-stage liver disease and primary liver cancer, and hence there is critical need for effective treatment. The goal of this clinical trial is to test whether low dose thyroid hormone administered to Veterans diagnosed with NASH can be an effective therapy mediated by improvement in breaking down fat in the mitochondria. The study will be conducted in two stages, the first stage is for proof of concept to be followed by interim analysis. If the interim analysis supports the merit for continuing the study, the clinical trial will proceed to stage 2 for continuation. This study will provide new information and strategies for treatment of NASH using low dose thyroid hormone that will be highly relevant and impactful to the health of the Veteran population.

Read the detailed description

Nonalcoholic steatohepatitis (NASH) is an aggressive part of the pathological spectrum of nonalcoholic fatty liver disease (NAFLD) that has evolved into a world-wide epidemic and is the most common chronic liver disease in the United States. NASH is strongly linked to obesity, and type 2 diabetes mellitus and may progress to cirrhosis and liver cancer. Disturbingly, prevalence rates of NASH appear to be greater in the Veteran population compared with the general US population. Thus, the burden of NASH is substantial to Veterans. Despite the recognition of NASH as a major public health problem, only lifestyle modifications aimed at increasing physical activity and reducing caloric intake are currently recommended as treatments with limited success. Thus, there is a great need for effective therapy of NASH. The goal of this study is to test whether low dose thyroid hormone administered to Veterans with biopsy-proven NASH, at a titrated dose (25, 50, or 75 mcg daily) that will maintain thyroid function within normal range (TSH at or above 0.47 mIU/L) can result in histological improvement of NASH, measured by significant reduction in nonalcoholic fatty liver disease score (NAS). The hypothesis is that low dose thyroid hormone causes histological improvement in NASH by increasing mitochondrial FAO in the liver mediated by an increase in mitochondrial trifunctional protein (MTP), the key enzyme in FAO cycle. The preliminary clinical studies in human subjects, including Veterans, support reduced FAO in NASH. In addition, preclinical in vivo animal studies and in vitro cell culture studies support that low dose thyroid hormone can effectively increase mitochondrial fatty acid oxidation and rescue NAFLD. In a randomized double-blinded placebo-controlled clinical trial, Veterans with normal thyroid levels and biopsy-proven NASH will be recruited and randomized to receive 52 weeks of either active treatment (low dose levothyroxine at 25, 50, or 75 mcg daily) or placebo control to accomplish the following Specific Aims. 1) To determine the efficacy of low dose thyroid hormone in improving NASH histological features. To accomplish this aim, NAS will be measured in pre- and post-liver biopsy samples. 2) To determine the effect of low dose thyroid hormone on mitochondrial FAO, MTP, and mitochondrial health markers in the liver compared to control. To accomplish this aim, mitochondrial FAO and the expression of genes supporting mitochondrial health will be measured in the pre- and post-liver biopsy samples. The primary clinical outcome is histological improvement in NASH measured by improvement in NAS and the secondary clinical outcome is improvement in fibrosis stage. The mechanistic outcomes include improvements in mitochondrial FAO, MTP, and quality markers. This project will be conducted in two stages. In stage 1 (proof-of-concept, 2 years), 32 Veterans with biopsy-proven NASH will be recruited and randomized to either the active treatment or placebo groups (16/group). At the end of the second year, interim analysis will be performed based on criteria that will include conditional power analysis for early efficacy to determine the probability that the full study will yield a statistically significant finding in the primary outcome (histological improvement in NASH) in the clinically relevant direction. Other milestones include trend in the secondary outcome, adverse events, and feasibility. The outcome from the proof-of-concept stage will guide the Go or No-Go decision to stage 2 for continuation of the study with recruitment of additional Veterans for a full 6-year clinical trial (total recruitment of 128 Veterans with biopsy-proven NASH: 64/active treatment group and 64/placebo control group). This project will exert a sustained and powerful impact in the field by providing new information and strategies for treatment of NASH that will be highly relevant and impactful to the health of the Veteran population.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improvement in Nonalcoholic fatty liver disease activity score (NAS) by 2 points

    To examine the efficacy of daily low dose Synthroid, using a dose-titration strategy based on serum thyroid stimulating hormone (TSH), on the histological progression of nonalcoholic steatohepatitis (NASH) in Veterans with normal serum TSH levels and biopsy-proven NASH, and to compare the treated patients with Veterans on placebo. Liver biopsies will be obtained at baseline (Week 0) and at end of treatment (Week 52). Nonalcoholic fatty liver disease activity score (NAS) will be assessed in baseline and post treatment liver biopsies and improvement in NAS will be compared between study group on active treatment and placebo group.

    Measured: 12 months

Secondary outcomes (4)
  1. Proportion of subjects experiencing improvement in biopsy-determined fibrosis by at least one stage

    The stage of liver fibrosis will be assessed in the study subjects at baseline and post intervention. Improvement in the stage of fibrosis will be compared between the placebo and study groups.

    Measured: 12 months

  2. Improvement in mitochondrial fatty acid oxidation

    Effect of Synthroid on mitochondrial fatty acid oxidation will be assessed by measurement of complete mitochondrial fatty acid oxidation in liver tissue obtained at baseline and post intervention (52 weeks) in study and placebo groups.

    Measured: 12 months

  3. Improvement in mitochondrial biogenesis

    Effect of Synthroid on mitochondrial biogenesis will be assessed by measurement of PCG-1alpha (peroxisome-proliferator-activated receptor gamma coactivator 1 alpha) gene expression in the liver tissue at baseline and post intervention at 52 weeks in the study and placebo groups.

    Measured: 12 months

  4. Improvement in mitochondrial mitophagy

    Effect of Synthroid on mitochondrial mitophagy will be assessed by measurement of BNIP3 (BCL2 interacting protein 3) gene expression in the liver tissue at baseline and post intervention at 52 weeks in the study and placebo groups.

    Measured: 12 months
