Primary Endpoint Met in Corcept’s Pivotal Phase 3 ROSELLA Trial of Relacorilant in Patients with Platinum-Resistant Ovarian Cancer
REDWOOD CITY, Calif.–(BUSINESS WIRE)–Mar. 31, 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, today announced that ROSELLA, the company’s pivotal Phase 3 trial of relacorilant plus nab-paclitaxel in patients with platinum-resistant ovarian cancer, met its primary endpoint of improved progression-free survival, as assessed by blinded independent central review (PFS-BICR).
In ROSELLA, patients treated with relacorilant in addition to nab-paclitaxel chemotherapy experienced a 30 percent reduction in risk of disease progression compared to patients treated with nab-paclitaxel alone (hazard ratio: 0.70; p-value: 0.008). Their median PFS-BICR was 6.5 months, compared to 5.5 months in patients who received nab-paclitaxel alone. At an interim evaluation of overall survival (OS), patients treated with relacorilant plus nab-paclitaxel had a significant improvement in OS, with a median OS of 16.0 months, compared to 11.5 months for patients receiving nab-paclitaxel alone (hazard ratio: 0.69; p-value: 0.012). Relacorilant was well-tolerated and no new safety signals were observed. As was the case in the company’s Phase 2 trial, safety and tolerability were comparable in the two groups.
Complete results from ROSELLA will be presented at a medical conference this year. Results from Corcept’s Phase 2 trial of relacorilant in patients with platinum-resistant ovarian cancer were published in the Journal of Clinical Oncology in June 2023.
