The trial

How NCT04944992 was run

The principal goal of this study is to determine the efficacy of efinopegdutide in liver fat reduction in participants with NAFLD. The primary hypotheses are that efinopegdutide is superior to semaglutide, or that efinopegdutide is superior to semaglutide by at least 10% with respect to mean relative reduction from baseline in liver fat content (LFC) after 24 weeks.

  • Efinopegdutide: Efinopegdutide 20 mg/mL administered by injection once weekly for 24 weeks in a dose-escalation regimen: 2.4 mg from day 1 to week 3, 5.0 mg from week 4 to 7, and 10.0 mg from week 8 to 24.
  • Semaglutide: Semaglutide 1.34 mg/mL administered by injection once weekly for 24 weeks in a dose-escalation regimen: 0.25 mg from day 1 to week 3, 0.5 mg from week 4 to 7, and 1.0 mg from week 8 to 24.
