Abstract
BACKGROUND: Resmetirom is approved for MASH F2-F3 fibrosis. Health-related quality of life (HRQL) was assessed in patients with MASH treated with resmetirom. METHODS: Patients with MASH enrolled in MAESTRO-NAFLD-1 (NCT04197479) and the 52-week open-label extension study (year 2). HRQL was assessed using LDQoL and CLDQ-NAFLD. Magnetic resonance imaging-proton density fat fraction (MRI-PDFF) response definition for early MASH: a decrease ≥30% from baseline; MASH cirrhosis ≥20% decrease (if baseline MRI-PDFF >5%). RESULTS: MAESTRO-NAFLD-1 included 180 patients with MASH cirrhosis and 1143 with early MASH [baseline MRI-PDFF ≥8%, vibration-controlled transient elastography (VCTE) ≥5.5 kPa <8.5 kPa] treated with 80 mg or 100 mg resmetirom or placebo or 100 mg open-label resmetirom. Baseline HRQL for MASH cirrhosis was significantly lower (up to -15% of score range) for all 6 domains of CLDQ-NAFLD and 13/17 domains of LDQoL (p<0.05). MASH cirrhosis, by week 24 of resmetirom treatment year 1, had improvements in Worry (CLDQ-NAFLD) and Health Distress (LDQoL) up to +4% of score range, sustained through week 52 and throughout year 2 (day 1, week 12, week 28) (p<0.05). Cirrhotic patients with MRI-PDFF response by year 1 week 52, improved in Stigma score (LDQoL): mean change (+3.9 vs. -4.2, p=0.042). Early MASH receiving resmetirom experienced improvement in: Abdominal and Worry (CLDQ-NAFLD) and Health Distress (LDQoL) (up to +5% of score range size); no similar improvements observed in placebo (all p>0.05). Early MASH patients with MRI-PDFF response experienced Abdominal and Worry score (up to +6%) improvements-greater than placebo or nonresponders. CONCLUSIONS: Early MASH and MASH cirrhosis treated with resmetirom experience improvement in some disease-specific HRQL scores.
