Phase 1 Trial.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07830758). This is a study registration, not published results. Lead sponsor: Madrigal Pharmaceuticals, Inc.. Recruitment status: NOT_YET_RECRUITING. Phase: PHASE1. Study type: INTERVENTIONAL. Enrollment: 90 participants (ESTIMATED). Conditions: MASH - Metabolic Dysfunction-Associated Steatohepatitis, Heart Failure With Preserved Ejection Fraction (HFPEF). Interventions: DRUG: Resmetirom; DRUG: Placebo. Primary outcome measures: Incidence of treatment-emergent adverse events (TEAEs) , From first dose through End of Study follow-up (28 days after last dose); Incidence of treatment-emergent serious adverse events (SAES) , From first dose through End of Study follow-up (28 days after last dose); Change from baseline in physical examination findings assessed by investigator physical examination , Baseline to Week 24; Change from baseline in body temperature , Baseline to Week 24; Change from baseline resting heart rate , Baseline to Week 24; Change from baseline in respiratory rate , Baseline to Week 24; Change from baseline in seated systolic blood pressure , Baseline to Week 24; Change from baseline in seated diastolic blood pressure , Baseline to Week 24; Change from baseline in PR interval on 12-lead ECG in milliseconds (ms) , Baseline to Week 24; Change from baseline in QRS interval on 12-lead ECG in milliseconds (ms) , Baseline to Week 24; Change from baseline in heart rate on 12-lead ECG in beats per minute (bpm) , Baseline to Week 24; Change from baseline in RR interval on 12-lead ECG in milliseconds (ms) , Baseline to Week 24; Change from baseline in QT interval on 12-lead ECG in milliseconds (ms) , Baseline to Week 24; Change from baseline in QT interval corrected using Bazett's formula (QTcB) in milliseconds (ms) , Baseline to Week 24; Change from baseline in QT interval corrected using Fridericia's formula (QTcF) in milliseconds (ms) , Baseline to Week 24; Number of participants with clinically significant abnormalities in hematology laboratory parameters , Baseline to Week 24; Number of participants with clinically significant abnormalities in blood chemistry laboratory parameters , Baseline to Week 24; Number of participants with clinically significant abnormalities in urinalysis parameters , Baseline to Week 24; Percent change from baseline in liver fat content measured by MRI-Proton Density Fat Fraction (MRI-PDFF) , Baseline to Week 24. Brief summary: 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.
