Journal of Clinical Oncology Publishes Results of Corcept’s Phase 2 Trial of Relacorilant in Women With Platinum-Resistant Ovarian Cancer
June 27, 2023 at 8:00 AM EDT
- 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 andSouth America
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.
“Outcomes for patients with platinum-resistant ovarian cancer are poor and treatment options are limited,” said first author of the publication
“We are excited by the data from our Phase 2 trial and enthusiastic the results have been published in the
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 are described as having “platinum-resistant” disease. In the
About Corcept’s Oncology Programs
There is substantial evidence that cortisol activity at the glucocorticoid receptor (“GR”) allows certain solid tumors to resist treatment and that modulating cortisol’s activity may help anti-cancer treatments achieve their intended effect.
Many types of solid tumors express the GR and are potential targets for cortisol modulation therapy. In some cancers, cortisol inhibits cellular apoptosis – the tumor-killing effect many treatments are meant to stimulate. In other cancers, cortisol activity promotes tumor growth. Cortisol also suppresses the body’s immune response; activating – not suppressing – the immune system is beneficial in fighting certain cancers.
Corcept is conducting clinical trials of its proprietary selective cortisol modulators in combination with three different anti-cancer treatments in patients with ovarian, adrenal and prostate cancers.
About Relacorilant
Relacorilant is a non-steroidal, selective glucocorticoid receptor modulator that does not bind to the body's other hormone receptors. Corcept is studying relacorilant in a variety of serious disorders, including ovarian, adrenal and prostate cancer and Cushing’s syndrome. Relacorilant is proprietary to Corcept and is protected by composition of matter and method of use patents, as well as orphan drug designation in the United States for the treatment of pancreatic cancer and both the United States and the European Union for the treatment of Cushing’s syndrome.
About Corcept Therapeutics
Corcept has discovered a large portfolio of proprietary compounds that selectively modulate the effects of cortisol and owns extensive
