Corcept to Present New Late-Breaking Data From Pivotal ROSELLA Trial of Relacorilant in Platinum-Resistant Ovarian Cancer at ESMO 2025

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, will present new data from its pivotal Phase 3 ROSELLA trial of relacorilant plus nab-paclitaxel in patients with platinum-resistant ovarian cancer at the 2025 European Society for Medical Oncology (ESMO) Annual Meeting. The data, which will be presented in a late-breaking oral presentation on Sunday, October 19, 2025, focuses on trial participants who were previously treated with a PARP inhibitor, a patient population with particularly poor prognosis.

(GOG-F), the European Network of Gynaecological Oncological Trial groups (ENGOT), the Asia-Pacific Gynecologic Oncology Trials Group (APGOT), the Latin American Cooperative Oncology Group (LACOG) and the Australia New Zealand Gynaecological Oncology Group (ANZGOG).

About Relacorilant

Relacorilant, an oral therapy, is a selective glucocorticoid receptor (GR) antagonist that modulates cortisol activity by binding to the GR but not to the body's other hormone receptors. Corcept is developing relacorilant in ovarian cancer and a variety of other serious disorders, including endogenous hypercortisolism and prostate cancer. Relacorilant is proprietary to Corcept and is protected by composition of matter, method of use and other patents. It has been designated an orphan drug by the FDA and the European Commission (EC) for the treatment of hypercortisolism and by the EC for the treatment of ovarian cancer. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) date of December 30, 2025 for relacorilant as a treatment for patients with hypercortisolism, and a PDUFA date of July 11, 2026 for relacorilant as a treatment for patients with platinum-resistant ovarian cancer.
