Corcept Therapeutics Initiates Phase 3 Trial of Relacorilant in Patients with Cushing’s Syndrome of Adrenal Origin

MENLO PARK, CA, USA I July 28, 2020 I Corcept Therapeutics Incorporated (NASDAQ: CORT), a commercial-stage company engaged in the discovery and development of drugs to treat severe metabolic, oncologic and psychiatric disorders by modulating the effects of cortisol, today announced enrollment of its first patient in GRADIENT, a double-blind, placebo-controlled, Phase 3 trial of relacorilant in patients with Cushing’s syndrome caused by adrenal adenomas or hyperplasia.

“We are excited to begin enrollment in GRADIENT,” said Andreas Grauer, MD, Corcept’s Chief Medical Officer.  “Patients with Cushing’s syndrome of adrenal origin have poor health outcomes, even if the course of their decline is sometimes less rapid than in Cushing’s syndrome of other etiologies.  GRADIENT is the first systematic study of the benefits of a medical treatment in these patients. We expect it to contribute meaningfully to physicians’ ability to provide optimal care.”

GRADIENT is a double-blind, placebo-controlled Phase 3 trial, with a planned enrollment of 130 patients at sites in the United States and Europe.  Half of the patients will receive relacorilant and the other half placebo for six months.  The trial’s primary endpoints are improvement in glucose metabolism and hypertension.1

GRADIENT is Corcept’s second Phase 3 trial of relacorilant in patients with hypercortisolism.  The company’s pivotal GRACE trial is enrolling 130 patients with all etiologies of Cushing’s syndrome at sites in the United States, Canada, Europe and Israel.  Corcept expects the results of GRACE, if positive, to be the basis for relacorilant’s new drug application as a treatment for all etiologies of Cushing’s syndrome.
