A Phase 3 Study to Evaluate the Efficacy and Safety of MGL-3196 (Resmetirom) in Patients With NASH and Fibrosis

Phase 3

Active, not recruiting

• Conditions: NASH - Nonalcoholic Steatohepatitis
• Interventions: Drug: MGL-3196; Drug: Placebo; Procedure: Liver Biopsy

• Registration Number: NCT03900429
• Lead Sponsor: Madrigal Pharmaceuticals, Inc.

Brief Summary

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

Detailed Description

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.

Recruitment & Eligibility

• Status: ACTIVE_NOT_RECRUITING
• Sex: All
• Target Recruitment: 1759

Inclusion Criteria

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)

Exclusion Criteria

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 coagulation.

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.

Primary Outcome Measures

Name	Time	Method
Week 52 Dual Primary Objectives: To determine the effect of 80 or 100 mg MGL-3196 vs matching placebo on liver biopsy (NASH CRN score) at Week 52 compared with Baseline	52 weeks	1. Proportion with resolution of NASH (ballooning 0, inflammation 0,1) associated with at least 2-point reduction in NAFLD Activity Score (NAS) without worsening of fibrosis stage OR; 2. Proportion with at least a 1-point improvement in fibrosis stage with no worsening of NAS
Month 54 Primary Objective: Time to experiencing an adjudicated Composite Clinical Outcome event (Final Primary Endpoint, at 54 months)	up to 54 months	The Composite Clinical Outcome is composed of all-cause mortality, liver transplant, and significant hepatic events (including hepatic decompensation events \[ascites, encephalopathy, or gastroesophageal variceal hemorrhage\], histological progression to cirrhosis, and a confirmed increase of MELD score from \<12 to ≥15).

Secondary Outcome Measures

Name	Time	Method
Week 52 Key Secondary Objective: To determine the effect of once-daily, oral administration of MGL-3196 80 or 100 mg versus matching placebo on the percent change from Baseline at 24 weeks in directly measured low-density lipoprotein cholesterol (LDL-C)	24 weeks	Assess the effect of MGL-3196 80 mg or 100 mg compared to placebo on LDL-C measured by percent change from Baseline at 24 weeks.
