Corcept Therapeutics Incorporated (NASDAQ: CORT), a commercial-stage company engaged in the discovery and development of medications to treat severe endocrinologic, oncologic, metabolic and neurologic disorders by modulating the effects of the hormone cortisol, has submitted a new drug application (NDA) to the U.S. Food and Drug Administration for its proprietary, selective cortisol modulator, relacorilant, to treat patients with endogenous hypercortisolism (Cushing’s syndrome).

Corcept’s NDA is based on positive results from the pivotal GRACE trial and confirmatory evidence from the Phase 3 GRADIENT and long-term extension studies and a Phase 2 study in hypercortisolism. Patients in these studies who received relacorilant experienced improvements in a wide array of hypercortisolism’s signs and symptoms, with an acceptable safety burden.

Notably, there were no instances of drug-induced adrenal insufficiency, hypokalemia or QT prolongation – serious adverse events that can arise in patients taking currently approved medications – and no adverse events associated with activity at the progesterone receptor, such as endometrial thickening or vaginal bleeding.

“Relacorilant’s combination of efficacy and safety give it the potential to become the standard of care for the medical treatment of patients with hypercortisolism,” said Joseph Belanoff, MD, Corcept’s Chief Executive Officer. “Our commitment to the health of patients with hypercortisolism is unwavering. We are optimistic that relacorilant will be of great benefit to them.”
