Background & aims: Nonalcoholic steatohepatitis (NASH) is a chronic liver disease associated with adverse clinical outcomes and impaired health-related quality of life (HRQL).
Methods: Patients with biopsy-proven non-cirrhotic NASH with hepatic fat fraction of ≥10% by magnetic resonance imaging-proton density fat fraction were enrolled in a phase 2, multicenter, double-blind, randomized, placebo-controlled study of resmetirom. HRQL was assessed using Short Form-36 throughout 36 weeks of treatment.
Results: One hundred twenty-five NASH patients were enrolled (50 ± 11 years old, 50% male, 94% white, body mass index 35 ± 6 kg/m2, 39% with diabetes mellitus). Of these, 84 patients received 80 mg of resmetirom daily, and 41 received placebo. At baseline, HRQL scores were not different from general population norms (Physical Component Summary [PCS] 47.9 ± 9.3 vs 50, Mental Component Summary 50.4 ± 10.0 vs 50; all P > .05). By treatment week 12, patients who received resmetirom experienced improvement of Bodily Pain and Short Form-6D utility scores (P < .05); no HRQL improvement was noted in placebo (all P > .05). Improvement in PCS continued up to week 36 of treatment with resmetirom, again with no improvement in placebo group (all P > .05). Adjusted for the baseline score and clinicodemographic confounders, meeting the endpoint of a decrease in proton density fat fraction of ≥30% by week 12 (met by 54 of 116 treatment completers; 47 of 54 on resmetirom) was independently associated with greater improvements in Physical Functioning and PCS scores at week 36 (P < .05). Patients with improvement in NASH and fibrosis on liver biopsy also showed improvement in components of HRQL.
Conclusions: Patients with NASH treated who improved their hepatic fat fraction and/or Nonalcoholic Fatty Liver Disease Activity Score on serial liver biopsy experienced improvement of HRQL. Further studies are needed to confirm long-term sustainability of that improvement. ClinicalTrials.gov #NCT02912260.
