A Phase 1b, Open-Label Study Evaluating the Pharmacokinetics and Safety of Miricorilant in Adult Patients With Presumed Metabolic Dysfunction-Associated Steatohepatitis (MASH)

Approximately 15 patients who are eligible for participation in the study will be administered a single dose of 60 mg of miricorilant. The maximum expected duration of a patient's participation is 56 days (up to 28 days of screening, followed by single-dose administration and 4 days of observation, and then 24 days of follow-up).

Inclusion Criteria:

• Evidence of presumed MASH with either FibroScan liver stiffness measurement ≥ 8 kPa and controlled attenuation parameter (CAP) ≥ 280 dB/m OR historical biopsy within 12 months of screening that meets the following criteria:

  1. Nonalcoholic fatty liver disease (NAFLD) activity score (NAS) ≥ 3 with at least ≥ 1 point in any two subcomponents of steatosis, inflammation, and ballooning, and a Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) fibrosis score of F1 OR
  2. NAS ≥ 2 with at least ≥ 1 point in any two subcomponents of steatosis, inflammation, and ballooning, and a NASH CRN fibrosis score of F2 or 3.

• Aspartate aminotransferase (AST) > 17 U/L for women and AST > 20 U/L for men. The AST inclusion criterion does not apply to participants with an eligible historical liver biopsy performed within 12 months of Screening.

• Presence of at least 1 of the following metabolic conditions that increase the risk of MASH:

  1. Diagnosis of type 2 diabetes OR

  2. Presence of 2 or more components of metabolic syndrome:

     • Fasting blood glucose ≥ 100 mg/dL (5.6 mmol/L) or treatment for elevated blood glucose
     • Systolic blood pressure ≥ 130 mm Hg, diastolic blood pressure ≥ 85 mm Hg, or treatment for hypertension
     • Serum triglycerides ≥ 150 mg/dL (1.7 mmol/L) or drug treatment for elevated triglycerides
     • 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
     • 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 (men ≥ 90 cm [35.4 in]; women ≥ 80 cm [31.5 in] in Asians).

Exclusion Criteria:

• Women who are pregnant, planning to become pregnant, or are lactating.

• Have a BMI < 18 kg/m2 or > 45 kg/m2.

• Have significant alcohol consumption of more than 20 g per day for women and 30 g per day for men within 1 year prior to screening or score of ≥8 on AUDIT questionnaire

• Have had liver transplantation or plan to have liver transplantation during the study.

• Have type 1 diabetes.

• Have poorly controlled type 2 diabetes with a glycated hemoglobin (HbA1c)

  • 9.5%.

• Have any other chronic liver disease

• History of cirrhosis or evidence of cirrhosis by clinical, imaging, or liver biopsy evaluation

• Have hepatic decompensation

Other exclusion criteria may apply
