What this study is
This Phase 1b multicenter randomized double-blind placebo-controlled study evaluates the safety, tolerability and hepatic pharmacodynamic effects of resmetirom in adults with metabolic dysfunction-associated steatohepatitis (MASH) and heart failure with preserved ejection fraction (HFpEF). Participants are randomized 2:1 to resmetirom or placebo for 24 weeks.
What's being tested
- Resmetirom
Intervention · DRUG
Resmetirom (80 mg or 100 mg orally once daily based on body weight)
- Placebo
Intervention · DRUG
Matching placebo orally once daily
