Frequently asked questions about mifepristone

What is Mifepristone used for?

Mifepristone is an investigational small molecule being studied for use in breast cancer, weight-gain prevention, Cushing's disease, Cushing's syndrome, and major depressive disorder. It is in Phase 3 clinical development for Cushing's syndrome, with additional trials exploring its use in other conditions.

How does Mifepristone work?

Mifepristone works by blocking the effects of cortisol and other glucocorticoids at the receptor level. It is a glucocorticoid receptor antagonist, which means it binds to the receptor and prevents cortisol from activating it, potentially reducing the harmful effects of excess cortisol in conditions like Cushing's syndrome.

Who makes Mifepristone?

Mifepristone is being developed by Corcept Therapeutics Incorporated, a biopharmaceutical company traded on the NASDAQ under the ticker symbol CORT. The company is focused on therapies that modulate the effects of cortisol and other steroid hormones.

What phase is Mifepristone in?

Mifepristone is in Phase 3 clinical development for Cushing's syndrome, based on a completed Phase 3 trial. It remains investigational and has not been approved by the FDA for any indication. Other trials for different conditions are in Phase 1.

What clinical trials is Mifepristone in?

Mifepristone has been studied in five completed clinical trials. Notable trials include NCT00936741, a Phase 3 extension study in Cushing's syndrome, and NCT02014337, a Phase 1 study in metastatic triple negative breast cancer and other solid tumors. Other trials include NCT00698022 and NCT03258372 in healthy volunteers.

Is Mifepristone the same as CORLUX?

Yes, Mifepristone is also known as CORLUX. The Phase 3 extension study NCT00936741 is titled 'An Extension Study of CORLUX in the Treatment of Endogenous Cushing's Syndrome,' confirming that CORLUX is an alternative name for Mifepristone.
