Abstract

Progression of nonalcoholic steatohepatitis (NASH) is incompletely characterized. We analyzed data on longitudinal changes in liver histology, hepatic venous pressure gradient (HVPG), and serum markers of fibrosis in 475 patients with NASH with bridging fibrosis (F3) or compensated cirrhosis (F4) enrolled in two phase 2b, placebo-controlled trials of simtuzumab. The trials were terminated after 96 weeks because of lack of efficacy, so data from treatment groups were combined. Liver biopsies and HVPG measurements (only for patients with F4 fibrosis) were collected at screening and at weeks 48 and 96. Patients were assessed for Ishak fibrosis stage, hepatic collagen content and alpha-smooth muscle actin (by morphometry), NAFLD Activity Score (NAS), and serum markers of fibrosis. Associations with progression to cirrhosis (in patients with F3 fibrosis) and liver-related clinical events (in patients with F4 fibrosis) were determined. Progression to cirrhosis occurred in 22% (48/217) of F3 patients, and liver-related clinical events occurred in 19% (50/258) of patients with cirrhosis. Factors significantly associated with progression to cirrhosis included higher baseline values of and greater increases in hepatic collagen content, level of alpha-smooth muscle actin, and Enhanced Liver Fibrosis score. Similar factors, plus lack of fibrosis stage improvement (hazard ratio, 9.30; 95% confidence interval, 1.28-67.37), higher HVPG at baseline, and greater increase in HVPG over time, were associated with an increased risk of liver-related clinical events in patients with cirrhosis. Disease progression was not associated with the NAS at baseline or changes in NAS during treatment after adjustment for fibrosis stage. Conclusion: In patients with advanced fibrosis due to NASH, the primary determinant of clinical disease progression is fibrosis and its change over time.

  • Metabolic heterogeneity of study populations, particularly T2D comorbidity, remains an unexplored source of inconsistent outcomes with omega-3 PUFA therapy.

    “The metabolic heterogeneity of study populations, particularly regarding T2D comorbidity, remains an unexplored source of the inconsistent outcomes with omega-3 PUFA therapy.13,14”
  • Direct antifibrotic therapeutic actions may become more critical when liver disease is already too advanced to allow sufficient time for primarily causal therapeutics to act, since clinical progression of advanced fibrosis may occur more rapidly than previously anticipated.

  • Despite being negative, the biomaterial and data obtained during simtuzumab clinical trials have provided important pathogenetic and clinical insights into NASH and PSC.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
