Abstract Number: 5503
Lifyorli, in combination with nab-paclitaxel, was approved by the U.S. Food and Drug Administration (FDA) in March 2026 for the treatment of adults with platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who have received one to three prior systemic treatment regimens, at least one of which included bevacizumab. Lifyorli is the first FDA-approved selective glucocorticoid receptor antagonist (SGRA). It is included in the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines) as a preferred regimen for patients with platinum-resistant ovarian cancer.
The ROSELLA trial was conducted in collaboration with The GOG Foundation, Inc. (GOG-F), the European Network of Gynaecological Oncological Trial groups (ENGOT), the Asia-Pacific Gynecologic Oncology Trials Group (APGOT), the Latin American Cooperative Oncology Group (LACOG) and the Australia New Zealand Gynaecological Oncology Group (ANZGOG).
About 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. 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 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 oncogenic signaling 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.
Corcept is developing relacorilant in ovarian, endometrial, cervical, pancreatic and prostate cancers. 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 European Commission (EC) for the treatment of ovarian cancer. Corcept has submitted a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) for relacorilant to treat patients with platinum-resistant ovarian cancer.
About Lifyorli
Lifyorli (relacorilant), approved in combination with nab-paclitaxel, is the first U.S. Food and Drug Administration (FDA)-approved selective glucocorticoid receptor antagonist for adults with platinum-resistant ovarian cancer. Lifyorli is an oral medication taken the day before, the day of and the day after treatment with nab-paclitaxel. There is no biomarker requirement to receive Lifyorli. Lifyorli competitively binds to the glucocorticoid receptor (GR), where it enhances chemotherapy sensitivity by inhibiting cortisol’s suppression of apoptosis – the programmed cell death that chemotherapies such as nab-paclitaxel are meant to cause. Lifyorli does not have any effect at the body’s other steroid receptors.
It is included in the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines) as a preferred regimen for patients with platinum-resistant ovarian cancer.
Corcept is committed to timely patient access for Lifyorli. For questions regarding product availability, please contact Lifyorli Support at 1-85-LIFYORLI (1-855-439-6754).
LIFYORLI Indication & Usage
LIFYORLI is indicated in combination with nab-paclitaxel for the treatment of adults with platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who have received 1-3 prior systemic treatment regimens, at least one of which included bevacizumab.
IMPORTANT SAFETY INFORMATION
Contraindications:
LIFYORLI is contraindicated in patients receiving systemic glucocorticoids for lifesaving purposes (e.g., immunosuppression after organ transplantation) because LIFYORLI antagonizes the effect of glucocorticoids.
Warnings and Precautions:
Neutropenia and Severe Infections
LIFYORLI in combination with nab-paclitaxel can cause neutropenia, including febrile neutropenia and severe infections. There was one fatal event of septic shock with febrile neutropenia. Thirty-eight percent of patients initiated granulocyte colony-stimulating factor (G-CSF) during the first or second cycle of therapy.
Monitor complete blood counts prior to each weekly treatment with LIFYORLI in combination with nab-paclitaxel and as clinically indicated. Based on the severity of neutropenia, delay dose, reduce dose or permanently discontinue LIFYORLI in combination with nab-paclitaxel. Consider short-acting G-CSF administration as applicable. Consider the possibility of concurrent adrenal insufficiency, particularly in the setting of serious infection.
Adrenal Insufficiency
LIFYORLI is a reversible glucocorticoid receptor antagonist and can cause adrenal insufficiency. Adrenal insufficiency can occur at any time during treatment with LIFYORLI. The risk of adrenal insufficiency is increased in situations of stress, such as acute illness, infection, or surgery. Consider whether supplemental glucocorticoids are required in the perioperative period in patients who have received LIFYORLI within 30 days of surgery. Monitor patients receiving LIFYORLI for signs and symptoms of adrenal insufficiency. Withhold LIFYORLI and administer glucocorticoid therapy if adrenal insufficiency is suspected. High doses of supplemental glucocorticoids may be needed to overcome the glucocorticoid receptor antagonism produced by LIFYORLI. After resolution of adrenal insufficiency, resume previous dose, reduce dose or permanently discontinue LIFYORLI based on severity.
Exacerbation of Conditions Treated with Glucocorticoids
Use of LIFYORLI in patients taking systemic glucocorticoids for other conditions (e.g., autoimmune disorders) may exacerbate these conditions. LIFYORLI is a glucocorticoid receptor antagonist that may make systemic glucocorticoids less effective. Similarly, coadministration of systemic glucocorticoids may make LIFYORLI less effective. Monitor patients for reduced effectiveness of LIFYORLI and glucocorticoids in patients receiving both.
Embryo-Fetal Toxicity
LIFYORLI can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Verify pregnancy status of females of reproductive potential prior to initiating LIFYORLI treatment. Advise females of reproductive potential, including male patients with female partners of reproductive potential, to use effective contraception during treatment with LIFYORLI and for 1 week after the last dose.
Adverse Reactions:
Serious adverse reactions occurred in 35% of patients who received LIFYORLI in combination with nab-paclitaxel. Serious adverse reactions (≥2%) in patients were neutropenia (4%), pneumonia (3.2%), pleural effusion (3.2%), febrile neutropenia (2.1%), and fatigue (2.1%). Fatal adverse reactions (2.1%) in patients were septic shock (0.5%), cardiac arrest (0.5%), ischemic stroke (0.5%), and intestinal perforation (0.5%).
Permanent discontinuation of LIFYORLI in combination with nab-paclitaxel due to adverse reactions occurred in 9% of patients. The adverse reaction (>2%) that resulted in permanent discontinuation of LIFYORLI in patients was intestinal obstruction (2.6%). Dosage interruptions of LIFYORLI due to an adverse reaction occurred in 72% of patients. Adverse reactions (≥5%) that required dosage interruptions of LIFYORLI in combination with nab-paclitaxel in patients included neutropenia (44%), anemia (12%), and fatigue (7%). Adverse reactions requiring dose reductions of LIFYORLI included fatigue (1.6%), decreased appetite (1.2%), abdominal pain (0.5%), neutropenia (0.5%), edema (0.5%), and sciatica (0.5%). LIFYORLI should be interrupted or discontinued when nab-paclitaxel is interrupted or discontinued.
The most common adverse reactions (>20%) of patients treated with LIFYORLI plus nab-paclitaxel, including laboratory abnormalities, were decreased hemoglobin, decreased neutrophils, fatigue, nausea, diarrhea, decreased platelets, rash, and decreased appetite.
Drug Interactions:
Strong CYP3A Inducers: Avoid coadministration of LIFYORLI plus nab-paclitaxel with strong CYP3A inducers. Both relacorilant and paclitaxel are CYP3A substrates. Coadministration of strong CYP3A inducers can decrease concentrations of relacorilant and paclitaxel, which may reduce their effectiveness.
CYP2C8 and Moderate CYP3A Inducers: Monitor for reduced effectiveness of LIFYORLI plus nab-paclitaxel with CYP2C8 inducers and moderate CYP3A inducers. Paclitaxel is a substrate of CYP2C8 and CYP3A, and relacorilant is a CYP3A substrate. Coadministration of CYP2C8 and moderate CYP3A inducers can decrease concentrations of paclitaxel and relacorilant, which may reduce their effectiveness.
CYP2C8 Inhibitors: Monitor for increased adverse reactions and modify the dosage for adverse reactions as recommended. Paclitaxel is a substrate of CYP2C8. Coadministration of CYP2C8 inhibitors may increase concentrations of paclitaxel, which may increase the risk of adverse reactions.
CYP3A Substrates: Avoid concomitant use unless otherwise recommended in the Prescribing Information for CYP3A substrates. Relacorilant is a strong CYP3A inhibitor. Relacorilant increases exposure of CYP3A substrates which may increase the risk for adverse reactions related to these substrates.
Certain CYP2C8 Substrates: Avoid concomitant use unless otherwise recommended in the Prescribing Information for CYP2C8 substrates where minimal concentration changes may lead to reduced effectiveness. Relacorilant is a weak CYP2C8 inducer. Relacorilant decreases exposure of CYP2C8 substrates which may decrease the effectiveness related to these substrates.
Use in Specific Populations:
Lactation: Advise women not to breastfeed during treatment with LIFYORLI and for 1 week after the last dose.
Geriatric Use: A higher incidence of grade 3-4 adverse events and dosage modification occurred in patients aged ≥65 years compared to younger adult patients.
Hepatic Impairment: Avoid LIFYORLI in combination with nab-paclitaxel in patients with moderate or severe hepatic impairment (total bilirubin >1.5 to 10x ULN and any AST).
