Primary endpoint met in pivotal phase III GRACE trial of relacorilant in patients with hypercortisolism (Cushing’s Syndrome)

The GRACE study has two parts. On April 22, Corcept announced that patients in GRACE’s initial, open-label phase exhibited clinically meaningful and statistically significant improvements in hypertension, hyperglycemia and other symptoms experienced by patients with Cushing’s syndrome. Patients who exhibited pre-specified improvements in hypertension, hyperglycemia or both were given the opportunity to enter the trial’s randomized, double-blind withdrawal phase, in which half of the patients continued to receive relacorilant and half received placebo, for 12 weeks.

GRACE met its primary endpoint of loss of blood pressure control in the randomized withdrawal phase among patients receiving relacorilant as compared to placebo (odds ratio: 0.17; p-value: 0.02). Consistent with its known safety profile, relacorilant was well-tolerated in both phases of GRACE, with no differences in the randomized withdrawal phase between the relacorilant and placebo groups. Additional data will be presented at the Endocrine Society (ENDO) annual meeting in Boston (poster presentation, June 3) and the Heart in Diabetes (HiD) conference in Philadelphia (oral presentation, June 7). The company expects to submit its New Drug Application in the third quarter.

“The data from GRACE make a compelling case for the use of relacorilant in patients with endogenous hypercortisolism. That patients experienced clinically significant improvements in hypertension, hyperglycemia and the other signs and symptoms of Cushing’s syndrome, without significant safety burden, is greatly encouraging for physicians and the patients they seek to help,” said Rosario Pivonello, MD, PhD, Principal Investigator of the GRACE study and Professor of Endocrinology at Università Federico II di Napoli, Italy.
