Frequently asked questions about Miricorilant

What is miricorilant?

Miricorilant is an investigational small molecule developed by Corcept Therapeutics for metabolic conditions, including nonalcoholic steatohepatitis (NASH), also called metabolic dysfunction-associated steatohepatitis (MASH), and antipsychotic induced weight gain. It has been studied in Phase 1 and Phase 2 clinical trials.

What does miricorilant target?

Miricorilant targets the glucocorticoid receptor (GR). It is a small molecule designed to act on GR, a receptor involved in metabolic regulation. Corcept Therapeutics is developing miricorilant around this GR mechanism for metabolic indications such as NASH and MASH.

Who makes miricorilant?

Miricorilant is developed by Corcept Therapeutics Incorporated, which trades under the ticker CORT. The company has sponsored the clinical trial program for miricorilant, including Phase 1 pharmacokinetic studies and a Phase 2b study in NASH and MASH.

What phase is miricorilant in?

Miricorilant is in Phase 2 development. Its largest study, the Phase 2b MONARCH trial in NASH and MASH, has been completed. Miricorilant is investigational and has not been established as approved for any indication based on the completed trials.

What clinical trials is miricorilant in?

Miricorilant has been studied in four completed trials. These include the Phase 2b MONARCH study (NCT06108219) in NASH and MASH, a Phase 1 liver fat study in MASLD (NCT06947304), a Phase 1 pharmacokinetic and safety study (NCT07553663), and a Phase 1 drug interaction study (NCT05712265).
