Detailed Description

Type and design of the study: A randomized, placebo-controlled, double-blind, clinical trial to evaluate the efficacy of metadoxine as a therapy in patients with biopsy-proven nonalcoholic steatohepatitis. Population: Non-diabetic patients with nonalcoholic steatohepatitis diagnosed by liver biopsy through the "nonalcoholic fatty liver disease activity score" (NAS)> 3. Sample size: Considering a difference of at least 30% between groups, a confidence level of 95% (two-sided, significance 0.05), a statistical power of 80%, and an additional 20% for possible losses, we need 54 patients per group. Variables: Independent: Treatment group (metadoxine / placebo). Dependents: – "Nonalcoholic fatty liver disease activity score" (NAS):0 a 8 – Degree of liver steatosis: 0 a 3 – Degree of lobular inflammation: 0 a 3 – Degree of ballooning: 0 a 2 – Degree of fibrosis: 0 a 2 – Weight: Kg – Body mass index: Kg/m2 – Waist circumference: cm – Serum alanine aminotransferase: U/L – Serum aspartate aminotransferase: U/L Methods: Those meeting the selection criteria will be invited to participate in this study, those who agree to participate must sign the consent form and will be randomized to placebo or metadoxine group. The duration of the therapy will be 6 months and after this period a second liver biopsy will be performed to assessed the improvement on liver histology.

Interventions

  • Drug: metadoxine
    • metadoxine 500mg tablets: 1 Tablet by mouth twice in day during 6 months
  • Other: placebo
    • placebo tablets: 1 Tablet by mouth twice in day during 6 months

Arms, Groups and Cohorts

  • Placebo Comparator: Group 1: Placebo
    • Placebo
  • Experimental: Group 2: Metadoxine
    • therapy with metadoxine

Clinical Trial Outcome Measures

Primary Measures

  • improvement in the degree of non-alcoholic fatty liver disease score (NAS)
    • Time Frame: 6 months
    • Non-alcoholic fatty liver disease score (NAS) is an histological classification to assessed the severity of liver steatosis, lobular inflammation and ballooning in the liver biopsy. It is measured on a scale from 0 to 8

Secondary Measures

  • improvement in liver steatosis measured on a scale from 0 to 3
    • Time Frame: 6 months
    • Liver biopsy: measured on a scale from 0 to 3
  • improvement in lobular inflammation measured on a scale from 0 to 3
    • Time Frame: 6 months
    • Liver biopsy: measured on a scale from 0 to 3
  • improvement in ballooning measured on a scale from 0 to 2
    • Time Frame: 6 months
    • Liver biopsy: measured on a scale from 0 to 2
  • improvement in alanine aminotransferase serum levels
    • Time Frame: 6 months
  • improvement in aspartate aminotransferase serum levels
    • Time Frame: 6 months
  • improvement in the degree of liver fibrosis measured on a scale from 0 to 2
    • Time Frame: 6 months
    • Liver biopsy: measured on a scale from 0 to 2
  • to compare the occurrence of adverse effects between groups
    • Time Frame: 6 months

Participating in This Clinical Trial

Inclusion Criteria

  • Non-diabetic patients, – Overweight or with obesity degrees I, II or III according to WHO criteria (BMI ≥ 25), – With evidence of liver steatosis in the ultrasonography, – With biopsy-proven nonalcoholic steatohepatitis, with ≥ 3 in the NAS score (at least 1 point for liver steatosis, at least 1 point for lobular inflammation, and at least 1 point for ballooning), – With or without fibrosis in the liver biopsy, but if it is present must be ≤ 2 on a scale of 4, where 4 is equivalent to cirrhosis.
