About this study
This study will evaluate the safety, pharmacokinetics (how the body absorbs, distributes, metabolizes, and eliminates the drug), and pharmacodynamics (how the drug affects the body) of resmetirom in children and adolescents with metabolic dysfunction-associated steatohepatitis (MASH) and liver fibrosis. Participants will receive oral resmetirom once daily for approximately 14 days at one of several dose levels. The information from this study will help determine appropriate dosing and further evaluate the safety and biological effects of resmetirom in pediatric participants with MASH.

- ✓ 1. Male or female participants 6 to 17 years of age, inclusive.
- ✓ 2. Parent(s) or legal guardian(s) able to provide written informed consent (as required by local regulations), with participant assent obtained as applicable.
- ✓ 3. Diagnose of MASH with fibrosis stage F1-F3 based on a liver biopsy obtained within 24 months before Screening.
- ✓ 4. Hepatic fat fraction ≥8% by magnetic resonance imaging-proton density fat fraction (MRI-PDFF) obtained during the Screening period.
- ✓ 5. Able to swallow study tablets.
- ✓ 6. Females of childbearing potential must have a negative pregnancy test at screening, must not be pregnant or breastfeeding, and must agree to use a highly effective method of contraception during the study and for at least 30 days after the last dose of study drug.

You may not qualify if…

- ✕ 2. Clinically significant liver disease other than MASH or evidence of cirrhosis (F4), decompensated liver disease, or other hepatic conditions that may interfere with study participation or interpretation of results.
- ✕ 3. Clinically significant thyroid disease or use of thyroid replacement therapy, triiodothyronine, thyroxine, or other prohibited thyroid medications.
- ✕ 4. Use of prohibited concomitant medications, including medications known to affect hepatic steatosis or liver function, lipid-lowering therapies, CYP2C8 inhibitors, OATP1B1/OATP1B3/BCRP inhibitors, protease inhibitors, St. John's Wort, or other medications prohibited by the protocol.
- ✕ 5. Use of glucagon-like peptide-1 (GLP-1) receptor agonists unless on a stable dose for at least 24 weeks before screening.
- ✕ 6. Clinically significant alcohol or substance abuse, or regular use of tobacco/nicotine products within 6 months before screening.
- ✕ 7. Active or clinically significant infection, including chronic hepatitis B or hepatitis C infection, HIV infection, or other immunocompromising conditions.
- ✕ 8. History or presence of clinically significant cardiovascular, pulmonary, renal, gastrointestinal, neurologic, hematologic, endocrine, psychiatric, or other medical conditions that, in the opinion of the Investigator, could interfere with study participation or interpretation of study results.
