Abstract

Background The bile acid derivative 6-ethylchenodeoxycholic acid (obeticholic acid) is a potent activator of the farnesoid X nuclear receptor that reduces liver fat and fibrosis in animal models of fatty liver disease. We assessed the efficacy of obeticholic acid in adult patients with non-alcoholic steatohepatitis.Methods We did a multicentre, double-blind, placebo-controlled, parallel group, randomised clinical trial at medical centres in the USA in patients with non-cirrhotic, non-alcoholic steatohepatitis to assess treatment with obeticholic acid given orally (25 mg daily) or placebo for 72 weeks. Patients were randomly assigned 1:1 using a computer-generated, centrally administered procedure, stratified by clinical centre and diabetes status. The primary outcome measure was improvement in centrally scored liver histology defined as a decrease in non-alcoholic fatty liver disease activity score by at least 2 points without worsening of fibrosis from baseline to the end of treatment. A planned interim analysis of change in alanine aminotransferase at 24 weeks undertaken before end-of-treatment (72 weeks) biopsies supported the decision to continue the trial (relative change in alanine aminotransferase -24%, 95% CI -45 to -3). A planned interim analysis of the primary outcome showed improved efficacy of obeticholic acid (p=0·0024) and supported a decision not to do end-of-treatment biopsies and end treatment early in 64 patients, but to continue the trial to obtain the 24-week post-treatment measures. Analyses were done by intention-to-treat. This trial was registered with ClinicalTrials.gov, number NCT01265498.Findings Between March 16, 2011, and Dec 3, 2012, 141 patients were randomly assigned to receive obeticholic acid and 142 to placebo. 50 (45%) of 110 patients in the obeticholic acid group who were meant to have biopsies at baseline and 72 weeks had improved liver histology compared with 23 (21%) of 109 such patients in the placebo group (relative risk 1·9, 95% CI 1·3 to 2·8; p=0·0002). 33 (23%) of 141 patients in the obeticholic acid developed pruritus compared with nine (6%) of 142 in the placebo group.Interpretation Obeticholic acid improved the histological features of non-alcoholic steatohepatitis, but its long-term benefits and safety need further clarification.Funding National Institute of Diabetes and Digestive and Kidney Diseases, Intercept Pharmaceuticals.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • FXR regulates other pathways with direct antiinflammatory and antifibrotic effects.

    “In addition, FXR regulates other pathways with direct antiinflammatory and antifibrotic effects. 13-15”

    From A Placebo-Controlled Trial of Obeticholic Acid in Primary Biliary Cholangitis (2016) · cites this paper as [14]

    The Discussion’s Systematic review says FXR agonists have indirect anti-fibrotic effects in animal models, contrary to the claim of direct anti-fibrotic effects. The cited passages do not describe direct anti-inflammatory effects or identify such pathways; page numbers are unavailable in our copy. (LLM, conf=0.84)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • In the FLINT trial, pruritus was the main side effect of obeticholic acid (33% vs. 6% placebo).

    “Pruritus was the main side effect of obeticholic acid (33% vs. 6% placebo) [46].”

    From Current treatment of non‐alcoholic fatty liver disease (2022) · cites this paper as [46]

    The Results identify pruritus as the symptom that differed between groups, supporting its description as the main side effect. But 33 is the number of obeticholic acid-treated patients who reported pruritus, not the percentage: the rates were 23% versus 6% with placebo. (LLM, conf=0.94)

    Experimental — accuracy not yet measured
  • In the FLINT trial, obeticholic acid improved fibrosis in 35% of patients versus 19% in the placebo arm (p = 0.004).

    “Importantly however obeticholic acid improved fibrosis in 35% of patients versus only 19% in the placebo arm (p = 0.004) [46].”

    From Current treatment of non‐alcoholic fatty liver disease (2022) · cites this paper as [46]

    The Results section states that more patients assigned to obeticholic acid than placebo had improvement in fibrosis. The passages in our copy do not give the claimed fibrosis-specific rates of 35% versus 19% or p = 0.004; the nearby 45% versus 21% result concerns a different, primary histological outcome. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • In the FLINT trial, significantly more patients in the obeticholic acid arm (45%) versus placebo (21%) showed improved liver histology (decrease in NAS ≥2 points without worsening of fibrosis).

    “Significantly more patients in the obeticholic acid arm (45%) versus placebo (21%) showed improved liver histology [46] (defined as decrease in NAS ≥2 points without worsening of fibrosis).”

    From Current treatment of non‐alcoholic fatty liver disease (2022) · cites this paper as [46]

  • In the FLINT trial, no statistically significant effect on the resolution of NASH was seen with obeticholic acid.

    “Nevertheless, while the primary endpoint was reached, no statistically significant effect on the resolution of NASH was seen, which could limit direct clinical usefulness.”

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.
