FDA Files Corcept's New Drug Application for Relacorilant as a Treatment for Patients with Platinum-Resistant Ovarian Cancer
FDA assigns a Prescription Drug User Fee Act (PDUFA) date of July 11, 2026
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, today announced that the U.S. Food and Drug Administration (FDA) has accepted Corcept's New Drug Application (NDA) for relacorilant as a treatment for patients with platinum-resistant ovarian cancer. The FDA has assigned a PDUFA date of July 11, 2026 for the application.
Corcept's NDA is based on positive data from its pivotal Phase 3 ROSELLA and Phase 2 trials. In these trials, patients who received relacorilant plus nab-paclitaxel experienced improved progression-free and overall survival compared to patients who received nab-paclitaxel monotherapy, with no need for biomarker selection. Relacorilant was well-tolerated, consistent with its known safety profile. Importantly, relacorilant conferred its benefit without increasing the safety burden of the patients who received it. The type, frequency and severity of adverse events in the combination arms were similar to those in the nab-paclitaxel monotherapy arms.
"The FDA's acceptance of our NDA brings us closer to offering a much-needed treatment option to patients with this dire disease," said Joseph Belanoff, M.D., Corcept's Chief Executive Officer. "Relacorilant has the potential to redefine how platinum-resistant ovarian cancer is treated."
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.
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.
About Corcept Therapeutics
For over 25 years, Corcept has focused on cortisol modulation and its potential to treat patients with a wide variety of serious disorders, leading to the discovery of more than 1,000 proprietary selective cortisol modulators and glucocorticoid receptor antagonists. Corcept is conducting advanced clinical trials in patients with hypercortisolism, solid tumors, ALS and liver disease. In February 2012, the company introduced Korlym®, the first medication approved by the U.S. Food and Drug Administration for the treatment of patients with endogenous hypercortisolism. Corcept is headquartered in Redwood City, California. For more information, visit Corcept.com.
