Corcept Therapeutics ^Company

Since our founding in May 1998 we have been focused on the impact of cortisol and the potential benefits of developing glucocorticoid receptor antagonists. About 80 percent of the tissues in the body have receptors for cortisol, and the effects of excess cortisol are severe and often life-threatening. Our initial research has been with mifepristone, which potently blocks the cortisol receptor. On February 17, 2012, the FDA approved Korlym® (mifepristone) in the United States as a once-daily oral medication for treatment of hyperglycemia secondary to hypercortisolism in adult patients with endogenous Cushing's syndrome who have type 2 diabetes mellitus or glucose intolerance and have failed surgery or are not candidates for surgery. Mifepristone is also being studied in a phase 3 trial, evaluating the impact of cortisol blockade on the psychotic features of psychotic depression. We plan to continue enrolling patients in this study throughout 2013.
