What researchers measure

Primary outcomes

  1. Percentage Change From Baseline in Magnetic Resonance Imaging-proton Density Fat Fraction (MRI-PDFF)

    Evaluate the effect of seladelpar on hepatic fat fraction, as assessed by magnetic resonance imaging-proton density fat fraction (MRI-PDFF) at Week 12 in the double-blind (DB) phase. MRI-PDFF Relative (Percent) Change From Baseline to Week 12 - ANCOVA - mITT Population MRI-PDFF exam was used to quantify the hepatic proton density fat fraction noninvasively. The fat fraction is the proportion of mobile protons in liver tissue attributable to fat and thus, is a noninvasive magnetic resonance-based biomarker of liver triglyceride concentration.

    Time frame: Week 12

Secondary outcomes

  1. Percentage of Participants With Improvement of 2 Points or More in the Nonalcoholic Fatty Liver Disease Activity Score (NAS)

    Histopathology nonalcoholic fatty liver disease activity score (NAS) change from baseline ≤-2 (Improvements of 2 points or more in NAS) - mITT Population Total NAS score represents the sum of scores for steatosis, lobular inflammation, and ballooning, and ranges from 0-8. Diagnosis of NASH (or, alternatively, fatty liver not diagnostic of NASH) should be made first, then NAS is used to grade activity. NAS scores of 0-2 occurred in cases largely considered not diagnostic of NASH, scores of 3-4 were evenly divided among those considered not diagnostic, borderline, or positive for NASH. Scores of 5-8 occurred in cases that were largely considered diagnostic of NASH

  3. Percent Change From Baseline in Aspartate Aminotransferase (AST) at Week 12 and Week 52

    Relative (Percent) Change of Aspartate Aminotransferase (AST) From Baseline to Weeks 12 and Week 52 - mITT Population A decreased serum levels of Aspartate Aminotransferase (AST) is a marker of liver function improvement.

    Time frame: Weeks 12, Week 52

  4. Percent Change From Baseline in Gamma Glutamyl Transferase (GGT) at Week 12 and Week 52

    Relative (Percent) Change of Gamma Glutamyl Transferase (GGT) From Baseline to Weeks 12 and Week 52 - mITT Population A decreased serum levels of Gamma Glutamyl Transferase (GGT) is a marker of liver function improvement.

  5. Number of Participants With Decrease in MRI-PDFF ≥ 30% From Baseline at Week 12 and Week 52

    Number of Participants with a relative decrease in MRI-PDFF ≥30% (ie, percent change ≥ 30%) at Weeks 12, and 52/ET (Early Termination) in the DB phase - mITT Population. MRI-PDFF exam was used to quantify the hepatic proton density fat fraction noninvasively. The fat fraction is the proportion of mobile protons in liver tissue attributable to fat and thus, is a noninvasive magnetic resonance-based biomarker of liver triglyceride concentration. MRI-PDFF response defined as ≥30% relative decline in MRI-PDFF is associated with ≥1 stage improvement in fibrosis and may be used as a surrogate marker of fibrosis regression in early phase clinical trials for NASH

    Time frame: Week 12, Week 52

  6. Percentage Change From Baseline in Magnetic Resonance Imaging-proton Density Fat Fraction (MRI-PDFF) at Week 52

    Percentage Change from Baseline in MRI-PDFF to Weeks 52//ET - mITT Population MRI-PDFF exam was used to quantify the hepatic proton density fat fraction noninvasively.

  7. Number of Liver Biopsy Responders With Reversal of NASH Reversal of NASH (Ballooning Score of 0 and Lobular Inflammation Score of 0 or 1) and no Worsening of Hepatic Fibrosis at Week 52

    Liver Biopsy Responders with reversal of NASH (ballooning score of 0 and lobular inflammation score of 0 or 1 and no worsening of hepatic fibrosis) at Week 52/ET. The reversal of NASH was defined as the absence of hepatocellular ballooning (score of 0) and no or minimal inflammation (lobular inflammation score of 0 or 1).
