New drug miricorilant tested for fatty liver disease safety
NCT ID NCT07553663
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study is testing a single dose of the drug miricorilant in 15 adults with MASH (a type of fatty liver disease) or MASH with cirrhosis. The main goal is to see how the body processes the drug and whether it is safe. This is not a test of whether the drug works, but rather a first step to gather important safety information.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- miricorilant
- What this could lead to
- If successful, this study could provide early safety data to support larger trials of miricorilant for MASH.
- What could go wrong
- This is a very early, small Phase 1b study with only 15 participants, focused on safety and drug levels—not on whether the drug works. It may not lead to an effective treatment.
Why investors are watching
Corcept Therapeutics is running a small Phase 1b trial of its drug miricorilant in 15 adults with MASH, a common liver disease. For a small company, this early safety and drug-level readout matters because it tests whether miricorilant works well enough in the body to justify moving into larger, more expensive studies. A clear result could shape Corcept's pipeline value beyond its existing products.
If it works: If miricorilant shows acceptable safety and predictable drug levels in these patients, Corcept could advance the drug to later-stage trials. That progress would broaden the company's portfolio and reduce reliance on its current treatments.
If it fails: Phase 1 trials often fail on safety or dosing grounds, and this one has only 15 participants, so results may be inconclusive. A poor outcome or a delay could set back the drug's development and leave Corcept with fewer pipeline options.

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.

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
