 hypercortisolism and determine their optimal treatment.

Relacorilant. We are developing our proprietary, selective cortisol modulator, relacorilant, as a treatment for patients with hypercortisolism. Relacorilant shares Korlym’s affinity for the glucocorticoid receptor (“GR”) but, unlike Korlym, has no affinity for the progesterone receptor (“PR”) and so is not the “abortion pill” and does not cause other effects associated with

PR affinity, including endometrial thickening and vaginal bleeding. Because relacorilant does not meaningfully 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 a New Drug Application (“NDA”) to the United States Food and Drug Administration (“FDA”) seeking approval to market relacorilant as a treatment for patients with endogenous hypercortisolism. In March 2025, the FDA accepted the NDA for filing and assigned a Prescription Drug User Fee Act target action date (“PDUFA date”) of December 30, 2025. The NDA is based on positive results from our pivotal GRACE trial, with confirmatory evidence from our Phase 3 GRADIENT trial, our Phase 3 long-term extension study and our Phase 2 study. Patients in these trials exhibited clinically meaningful improvements in a wide range of hypercortisolism signs and symptoms, including hypertension, glucose control, weight and body composition. Relacorilant has been well-tolerated in all of its clinical 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 were eligible to proceed to GRACE’s second, double-blind, randomized withdrawal phase, in which half of the patients
