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.
About Cortisol’s Role in Oncology
Cortisol plays a role in tumor growth through several mechanisms. It helps solid tumors resist chemotherapy by inhibiting cellular apoptosis — the tumor-killing effect chemotherapy is meant to stimulate. In some cancers, cortisol promotes tumor growth by activating oncogenes in the cells to which it binds. Cortisol also suppresses the body’s immune response, which weakens its ability to fight all diseases, including cancer.
About Platinum-Resistant Ovarian Cancer
Ovarian cancer is the fifth most common cause of cancer death in women. Patients whose disease returns less than six months after receiving platinum-containing therapy have "platinum-resistant" disease. There are few treatment options for these women. Median overall survival following recurrence is approximately 12 months with single-agent chemotherapy. Approximately 20,000 women with platinum-resistant disease are candidates to start a new therapy each year in the United States, with at least an equal number in Europe.
