Primary Outcome Measures:
  • Methionine elimination half-life measured in blood. [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    After the methionine load, blood samples will be obtained at 0.5, 1, 1.5, 3, 4.5, 6, 7.5 and 9 hours. Plasma will be analyzed for methionine.

Secondary Outcome Measures:
  • Fasting methionine concentration and AUC (area under curve) of average methionine concentration versus time curve, the metabolic clearance rate and volume of distribution measured in blood. [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    After the methionine load, blood samples will be obtained at 0.5, 1, 1.5, 3, 4.5, 6, 7.5 and 9 hours. Plasma will be analyzed for methionine.

  • 13C (natural, stable isotope of carbon) Methionine breath test [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    parameters cPDR30 , cPDR60, cPDR 90 (cumulative percentage dose of 13C recovered after 30, 60, 90 minutes), peak and time to peak will be evaluated

  • Hepatic Panel (liver laboratory parameters) [ Time Frame: change from baseline at 6 weeks ] [ Designated as safety issue: No ]
    STB (Serum Total Bilirubin), SCB (Serum Conjugated Bilirubin), liver-ALP (alkaline phosphatase), ALT (alanine aminotransferase), AST (aspartate aminotransferase), GGT (Gamma Glutamyl Transpeptidase), ALT/AST ratio

  • Metabolic Panel (metabolic laboratory parameters) [ Time Frame: change from baseline at 6 weeks ] [ Designated as safety issue: No ]
    Fasting lipid profile (cholesterol, HDL (High Density Lipoprotein), LDL (Low Density Lipoprotein)), amino acid profile, homeostasis model assessment (HOMA-R) fasting plasma insulin, fasting glucose and glycosylated hemoglobin (HbA1c) as well as adiponectin

Other Outcome Measures:
  • Immunological/Anti-oxidant Panel (immunological and anti-oxidant laboratory parameters) [ Time Frame: change from baseline at 6 weeks ] [ Designated as safety issue: No ]
    CRP (C-reactive Protein), cytokine profile ( IL-6, IL-8, IL-10 (Interleukin),TNF-α (Tumor Necrosis Factor), MCP-1 (monocyte chemoattractant protein), and G-CSF (Granulocyte-colony stimulating factor )), glutathione in erythrocytes, oxidative stress marker (isoprostane level)

  • Fibrosis and Apoptosis Markers (fibrosis and apoptosis laboratory markers) [ Time Frame: change from baseline at 6 weeks ] [ Designated as safety issue: No ]
    Caspase-cleaved CK 18 (cytokeratin) (M30) (monoclonal antibody 30), Hyaluronic acid, ActiTest/Fibrotest
