MENLO PARK, CA--(Marketwire - April 10, 2012) - Corcept Therapeutics Incorporated (NASDAQ: CORT) announced today that Korlym™ (mifepristone) 300 mg Tablets is available by prescription nationwide.
On February 17, 2012, the U.S. Food and Drug Administration (FDA) approved Korlym as a once-daily oral medicine to control 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. Korlym is the first FDA-approved treatment for this illness.
"After using mifepristone in the company's clinical trial, I am pleased that it will be available for the medical management of my patients with Cushing's syndrome for whom surgery failed," said James W. Findling, M.D., Professor of Medicine, Endocrinology at the Medical College of Wisconsin. "The majority of patients in the trial had very gratifying improvements in the clinical and metabolic manifestations of hypercortisolism."
Korlym is a once daily oral medication. The medicine's FDA-approved labeling instructs physicians to titrate each patient's Korlym dose to clinical efficacy by assessing tolerability and degree of improvement in Cushing's syndrome manifestations. In the first six weeks, these manifestations may include changes in glucose control, anti-diabetic medication requirements, insulin levels and psychiatric symptoms. After two months, assessment may also be based on improvements in cushingoid appearance, acne, hirsutism, striae or decreased body weight, along with further changes in glucose control.
"Korlym offers a new treatment strategy that has the potential to improve the lives of many patients," said Joseph K. Belanoff, M.D., the company's Chief Executive Officer. "We have worked hard to make it available as quickly as possible."
"We are determined that every patient who could benefit from Korlym will receive it," added Steven Lo, Corcept's Vice President of Commercial Operations. "Our specialty pharmacy partner, Curascript, is prepared to dispense medicine. Our Support Program for Access and Reimbursement for Korlym (SPARK) is ready with case managers to help patients navigate their medical insurance coverage and identify the Corcept and charitable foundation support programs available to them."

About Cushing's Syndrome
Endogenous Cushing's syndrome is a rare and life-threatening endocrine disorder that results from long-term exposure to excess levels of the hormone cortisol. This excess is caused by tumors that usually occur in the pituitary or adrenal glands that over-produce, or prompt the over-production of, cortisol.
Although cortisol at normal levels is essential to health, in excess it causes a variety of problems, including glucose intolerance and diabetes, upper body obesity, a rounded face, stretch marks on the skin, an accumulation of fat on the back, thin and easily bruised skin, muscle weakness, bone weakness, persistent infections, high blood pressure, fatigue, irritability, anxiety, psychosis and depression. Women may have menstrual irregularities and facial hair growth, while men may have decreased fertility or erectile dysfunction. More than 70 percent of Cushing's syndrome patients suffer from glucose intolerance or diabetes.
If left untreated, Cushing's syndrome has a five-year mortality rate of 50 percent.
About Korlym™ (mifepristone) 300 mg Tablets
Korlym is a once-daily oral medication that blocks the glucocorticoid receptor type II (GR-II) to which cortisol normally binds. By blocking this receptor, Korlym inhibits the effects of excess cortisol in Cushing's syndrome patients. The FDA-approved labeling instructs physicians to titrate each patient's Korlym dose to clinical efficacy by assessing tolerability and degree of improvement in Cushing's syndrome manifestations.
The FDA has designated Korlym as an Orphan Drug, a special status designed to encourage the development of medicines for rare diseases and conditions. Because Korlym is an Orphan Drug, Corcept will have marketing exclusivity for the FDA-approved indication until February 2019.
