Official title: A Phase 1b, Multi-Center, Double-Blind (Sponsor Unblinded), Randomized, Placebo-Controlled Study of the Safety, Tolerability, and Hepatic Pharmacodynamics of Resmetirom in Patients With Metabolic Dysfunction-Associated Steatohepatitis (MASH) and Heart Failure With Preserved Ejection Fraction (HFpEF)

Run by Madrigal Pharmaceuticals, Inc. · NCT07830758 · Data updated 2026-11-12

This study tests whether resmetirom can be given safely and show liver-related effects in adults with MASH and heart failure with preserved ejection fraction over 24 weeks.

Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with fibrotic MASH and confirmed HFpEF, plus adequate kidney function and adherence to birth control requirements for those multiplying reproductive potential.

Probably not a fit

Patients without fibrotic MASH, without HFpEF, or with significant safety concerns may not experience benefit.

What this trial studies

This is a phase 1b, multicenter, randomized, double-blind, placebo-controlled trial evaluating the safety, tolerability, and hepatic pharmacodynamic effects of resmetirom in adults with fibrotic MASH and HFpEF. Participants are randomized 2:1 to receive resmetirom or placebo for 24 weeks. The trial includes adults with confirmed HFpEF, suspected or confirmed fibrotic MASH, and adequate kidney function, with plans for close safety monitoring. Primary endpoints focus on safety and tolerability, with secondary assessments related to liver pharmacodynamics. Locations include sites in Arizona, California, and Florida, sponsored by Madrigal Pharmaceuticals.

Why it matters

Potential benefit: If successful, participants may experience improvements in liver-related health markers and tolerability of resmetirom, potentially slowing MASH-related progression.

How similar studies have gone: Prior studies of resmetirom in liver disease have shown signals of liver-related pharmacodynamics and tolerability, supporting this exploratory, early-phase approach.

11. Serum ALT \>250 U/L
12. Platelet count \<140,000/mm3. Patients with platelets \<140,000 and ≥120,000/mm3 are eligible if FIB-4 score \<3.5.

14. Uncontrolled hypertension (either treated or untreated) defined as systolic blood pressure \>170 mmHg or a diastolic blood pressure \>100 mmHg at Screening
15. Confirmed QTcF \>450 msec for males and \>470 msec for females at the Screening ECG assessment;
16. Presence of sustained atrial fibrillation at time of Screening or history of paroxysmal atrial fibrillation episodes for the last 3 months prior to Screening
