CORCEPT THERAPEUTICS ANNOUNCES FIRST QUARTER 2005 RESULTS

MENLO PARK, Calif., (May 11, 2005) -- Corcept Therapeutics Incorporated (NASDAQ: CORT) today reported financial results for the first quarter ended March 31, 2005.
For the first quarter of 2005, Corcept reported a net loss of $5.5 million, or $0.24 per share, compared to a net loss of $2.6 million, or $0.29 per share, for the first quarter of 2004.
Total operating expenses were $5.8 million for the first quarter of 2005 compared to $2.6 million in the same period in 2004. In the first quarter of 2005, research and development expenses increased to $4.7 million from $1.6 million in the first quarter of 2004. This increase in research and development expenses over the prior year period was primarily related to increased activity in the clinical development of CORLUX® for the treatment of the psychotic features of psychotic major depression, or PMD.

General and administrative expenses increased to $1.1 million in the first quarter of 2005 from $1.0 million for the first quarter of 2004, attributable to increases in staffing, insurance costs, professional fees and other costs related to being a public company.

As of March 31, 2005, Corcept had cash, cash equivalents and marketable securities of $41.1 million. The total cash used in the company's operating activities for the first quarter was $5.7 million.

"Since the year began, we have made progress in our clinical and preclinical programs", said Joseph K. Belanoff, M.D., Chief Executive Officer of Corcept. "We have initiated our third Phase III clinical trial evaluating CORLUX for the treatment of the psychotic features of PMD. We have also initiated a study to evaluate the safety and tolerability of retreatment with CORLUX."

Dr. Belanoff added, "We recently completed preclinical studies showing that CORLUX has the potential to both reduce the weight gain caused by olanzapine (the active ingredient in the antipsychotic medication Zyprexa®) and to prevent the weight gain caused by the initiation of treatment with olanzapine. Enrollment continues in our phase II clinical trial in Alzheimer's disease. We expect to report results on this trial in the first half of 2006."

Dr. Belanoff further stated, "We believe that our cash and marketable securities will enable us to complete, as currently planned, the clinical development of our lead product candidate, CORLUX, for the treatment of the psychotic features of PMD."

Reiterating Corcept's financial guidance for 2005, Fred Kurland, Corcept's Chief Financial Officer, stated, "We continue to expect that net cash used in 2005 will be between $25 million and $30 million."

About Psychotic Major Depression
PMD is a serious psychiatric disorder that affects approximately three million people annually in the United States. It is more prevalent than either schizophrenia or manic depressive illness. The disorder is characterized by severe depression accompanied by delusions, hallucinations or both. People with PMD are approximately 70 times more likely to commit suicide than the general population and often require lengthy and expensive hospital stays. There is no FDA-approved treatment for PMD.
