A Phase 2b, Study Evaluating Miricorilant in Adult Patients With Nonalcoholic Steatohepatitis/Metabolic Dysfunction-Associated Steatohepatitis (MONARCH)

A Phase 2b, Randomized, Double-Blind, Placebo-Controlled Study Evaluating the Efficacy and Safety of Miricorilant in Adult Patients with Nonalcoholic Steatohepatitis (MONARCH)

Approximately 120 patients who are eligible for participation in the study will be randomized on Day 1 in a 2:1 ratio to 100 mg miricorilant or placebo twice weekly, for 48 weeks of treatment (Cohort A).

Approximately 75 patients who are eligible for participation in the study will be randomized on Day 1 in a 2:1 ratio to 100 mg miricorilant twice a week for 6 weeks of treatment, followed by a dose escalation to 200 mg miricorilant or placebo twice weekly for an additional 18 weeks which resulting in a total treatment duration of 24 weeks, or to placebo for 24 weeks. (Cohort B).

Eligibility Criteria:
Inclusion Criteria:

  * NAS ≥ 2 with ≥1 point in subcomponent of steatosis and ≥ 1 point in subcomponent of ballooning or inflammation and a NASH-CRN fibrosis score of F2 or 3
* AST \> 17 U/L for women and AST \> 20 U/L for men.
* FibroScan® liver stiffness measurement ≥ 8 kPa and CAP ≥ 280 dB/m.
* MRI-PDFF with ≥ 8% steatosis
* Presence of at least 1 of the following metabolic syndromes that increase the risk of NASH/MASH:

  1. Diagnosis of type 2 diabetes OR
  2. Presence of 2 or more components of metabolic syndrome:

  i. Fasting blood glucose ≥ 100 mg/dL (5.6 mmol/L) or treatment for elevated blood glucose ii. Systolic blood pressure ≥ 130mmHg, diastolic blood pressure ≥ 85mmHg, or treatment for hypertension iii. Serum triglycerides ≥ 150 mg/dL (1.7 mmol/L) or drug treatment for elevated triglycerides iv. Serum high-density lipoprotein (HDL) cholesterol \< 40 mg/dL (1 mmol/L) in men and \< 50 mg/dL (1.3 mmol/L) in women or drug treatment for low HDL v. Overweight or obese (body mass index \[BMI\] ≥ 25 kg/m2 \[BMI ≥ 23 kg/m2 in Asians\]), or increased waist circumference ≥ 102 cm (40 in) in men and ≥ 88 cm (35 in) in women (male ≥ 90 cm \[35.4 in\]; women ≥ 80 cm \[31.5 in\] in
