A double-blind placebo controlled randomized Phase 3 study to determine if 80 or 100 mg of MGL-3196 as compared with placebo resolves NASH and/or reduces fibrosis on liver biopsy and prevents progression to cirrhosis and/or advanced liver disease

Official Title

A Phase 3, Multinational, Double-Blind, Randomized, Placebo-Controlled Study of MGL-3196 (Resmetirom) in Patients With Non-Alcoholic Steatohepatitis (NASH) and Fibrosis to Resolve NASH and Reduce Progression to Cirrhosis and/or Hepatic Decompensation


Primary and secondary endpoint population at Week 52 will be at least 900 patients, more than half fibrosis score 3 (F3), the remainder fibrosis score 2 (F2) and <10% fibrosis score F1B (F1B) based on final liver biopsy baseline fibrosis score.


NASH - Nonalcoholic Steatohepatitis, Fatty Liver, Non-alcoholic Fatty Liver Disease, MGL-3196, Liver Biopsy

Open to people ages 18 years and up

  1. Must be willing to participate in the study and provide written informed consent.
  2. Male and female adults ≥ 18 years of age.
  3. Suspected or confirmed diagnosis of NASH fibrosis suggested by the historical data.

    Meet one of the following criteria that is consistent with NASH liver fibrosis:

    1. Historical biochemical test for fibrosis: PRO-C3 >14 ng/mL or ELF ≥9
    2. FibroScan with transient elastography ≥8.5 kPa and controlled attenuation parameter ≥280 dB.m-1
    3. Historical liver biopsy obtained <2 years before expected randomization showing Stage 1B, 2 or 3 fibrosis with NASH based on existing pathology review, with no significant change in body weight >5% or medication that might affect NAS or fibrosis stage.
  4. MRI-PDFF fat fraction ≥8% obtained during the screening period
  5. Biopsy-proven NASH (baseline liver biopsy) based on a liver biopsy obtained ≤6 months before anticipated date of randomization (if the biopsy is deemed acceptable for interpretation by the central reader) with fibrosis stage 1A/1C, 1B, 2, or 3 on liver biopsy and NAS of ≥4 with a score of at least 1 in each of the following NAS components:
    1. Steatosis (scored 0 to 3)
    2. Ballooning degeneration (scored 0 to 2)
    3. Lobular inflammation (scored 0 to 3)

You CAN'T join if...

  1. History of significant alcohol consumption for a period of more than 3 consecutive months within 1 year prior to Screening.
  2. Regular use of drugs historically associated with NAFLD
  3. Thyroid diseases:
    1. Active hyperthyroidism.
    2. Untreated clinical hypothyroidism defined by thyroid stimulating hormone (TSH) >7 IU/L with symptoms of hypothyroidism or >10 IU/L without symptoms.
    3. Patients who have had a thyroidectomy and are on replacement thyroxine doses >75 µg per day are allowed.
  4. History of bariatric surgery or intestinal bypass surgery within the 5 years prior to randomization or planned during the conduct of the study.
  5. Recent significant weight gain or loss
  6. HbA1c ≥ 9.0%.
  7. Glucagon-like peptide 1 [GLP-1] agonist, high dose Vitamin E (> 400 IU/day), or pioglitazone therapy unless stable dose for 24 weeks prior to biopsy.
  8. Presence of cirrhosis on liver biopsy defined as stage 4 fibrosis.
  9. Diagnosis of hepatocellular carcinoma (HCC).

    10. MELD score ≥12, as determined at Screening, unless due to therapeutic anti


    11. Hepatic decompensation 12. Chronic liver diseases other than NASH 13. Active autoimmune disease 14. Serum ALT > 250 U/L. 15. Active, serious medical disease with a likely life expectancy < 2 years. 16. Participation in an investigational new drug trial in the 60 days or 5 half-lives,

    whichever is longer.

    17. Any other condition which, in the opinion of the Investigator, would impede

    compliance, hinder completion of the study, compromise the well-being of the patient, or interfere with the study outcomes.
