Journal of Clinical Oncology Publishes Results of Corcept’s Phase 2 Trial of Relacorilant in Women With Platinum-Resistant Ovarian Cancer

• Relacorilant plus nab-paclitaxel improved progression-free survival (PFS), duration of response (DoR) and overall survival (OS), without increasing side effects, compared to nab-paclitaxel monotherapy
  
• Confirmatory Phase 3 ROSELLA trial underway, with planned enrollment of 360 patients in the United States, Europe, Canada, Israel, Asia and South America

MENLO PARK, Calif., June 27, 2023 (GLOBE NEWSWIRE) -- Corcept Therapeutics Incorporated (NASDAQ: CORT), a commercial-stage company engaged in the discovery and development of medications to treat severe endocrine, oncologic, metabolic and neurological disorders by modulating the effects of the hormone cortisol, today announced publication of the final analysis from its Phase 2 trial evaluating its proprietary cortisol modulator, relacorilant, in women with platinum-resistant ovarian cancer in the Journal of Clinical Oncology (JCO), the premiere journal of the American Society of Clinical Oncology (ASCO).

The publication is titled Relacorilant + Nab-Paclitaxel in Patients with Recurrent, Platinum-Resistant Ovarian Cancer: A Three-Arm, Randomized, Controlled, Open-Label Phase II Study and can be accessed at the following link: https://ascopubs.org/doi/full/10.1200/JCO.22.02624

In the trial, patients who received relacorilant orally the day before, the day of and the day after their nab-paclitaxel infusion (“intermittent dosing”) experienced a 34 percent reduction in risk of disease progression (median PFS=5.6 vs. 3.8 months, HR 0.66, P=0.038), responded to treatment longer (median DoR=5.6 vs. 3.7 months, HR 0.36, P=0.006) and had a 33 percent reduction in risk of death (median OS=13.9 vs. 12.2 months, HR 0.67, P=0.066) compared to patients who received nab-paclitaxel alone. Adverse events were comparable across the study arms.

PFS and OS benefits were exhibited across multiple subgroups of patients. Patients who would have met the eligibility requirements for Corcept’s confirmatory Phase 3 ROSELLA trial did especially well. A post-hoc analysis showed that patients who had received prior bevacizumab, did not have primary platinum-refractory disease and who had received no more than three prior lines of therapy experienced a 62 percent reduction in risk of death (median OS=17.9 vs. 12.6 months, HR 0.38, P=0.011) compared to similar patients who received nab-paclitaxel alone.
