 increase cortisol levels, it does not cause hypokalemia (low potassium), a potentially serious condition that is a leading cause of patients stopping treatment with Korlym. Forty-four percent of patients in Korlym’s pivotal trial experienced hypokalemia. Unlike all other medications used to treat hypercortisolism, relacorilant does not prolong the heart’s QT interval, a potentially deadly off-target effect.

In December 2024, we submitted an NDA to the FDA seeking approval to market relacorilant as a treatment for patients with endogenous hypercortisolism. The NDA is based on positive results from our pivotal trial “GRACE”, as well as confirmatory evidence from our Phase 3 “GRADIENT” trial, our Phase 3 long-term extension study and our Phase 2 study. In all of these trials, patients exhibited clinically meaningful improvements in a wide range of hypercortisolism signs and symptoms, including hypertension, glucose control, weight and body composition. Relacorilant was well-tolerated in all of the trials. Notably, patients did not experience some of the serious adverse events that can arise in patients taking Korlym or other currently approved treatments.

The GRACE trial had two parts. The first, open-label phase enrolled 152 patients with any etiology of hypercortisolism. Each patient received relacorilant for 22 weeks. Patients who exhibited pre-specified improvements in either hypertension, hyperglycemia or both symptoms proceeded to GRACE’s second, double-blind, randomized withdrawal phase, in which half of the patients continued to receive relacorilant and half received placebo for 12 weeks. GRACE’s primary endpoint was the number of patients in the relacorilant group who lost blood pressure control compared to the number who lost blood pressure control in the placebo group.

In the open-label phase, patients experienced clinically meaningful and statistically significant improvements in a wide-array of hypercortisolism signs and symptoms, including hypertension, hyperglycemia, weight, waist circumference, fat and lean body mass, cognition and Cushing’s Quality of Life score. Rapid and sustained improvements in systolic blood pressure (“SBP”) and diastolic blood pressure (“DBP”) were observed in all patients with hypertension, with an improvement in mean SBP of 7.9 mm Hg and mean DBP of 5.4 mm Hg at 22 weeks (p-values: <0.
