Eligibility
Inclusion criteria
Inclusion criteria: 1. Have completed a Corcept-sponsored study of relacorilant in endogenous Cushing syndrome. 2. According to Investigator’s opinion will benefit from treatment with relacorilant. 3. Provide written informed consent. 4. If a female of childbearing potential, patients must be willing to use a highly effective method of contraception from 30 days before study entry until 28 days after the last dose of study drug. Male patients with a female partner must agree to 2 forms of contraception, one of which must be a double-barrier method, from study entry until 28 days after the last dose of study drug. Highly effective methods of contraception are detailed in the protocol. 5. Are willing to continue to refrain from using drugs that inhibit steroid biosynthesis by the adrenal cortex or ACTH secretion by a pituitary or extrapituitary ACTH secreting tumor. 6. Are able to return to the investigative site to complete the study evaluations outlined in the protocol. 7. For patients with Cushing syndrome due to an ACTH-secreting pituitary tumor, are able to obtain pituitary MRI imaging (up to 3 months before starting treatment in this study, or up to 6 weeks after start of treatment in this study) to assess changes in tumor size during dosing. A CT scan can be used instead in patients for whom MRI is contraindicated. 8. Patients who enter study >8 weeks after last dose in the parent study have active disease. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 45 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 30
Exclusion criteria
Exclusion criteria: 1. Have been prematurely discontinued from relacorilant study treatment in the parent study for any reason 2. Are planning to start another Cushing syndrome drug after starting participation in this extension study. 3. Have an acute or unstable medical problem that could be aggravated by relacorilant treatment. 4. Are taking the following medications from the times specified below before the Study CORT125134-452 Day 1 visit and/or through the entire study period: • Medications used in the treatment of Cushing syndrome, with the exception of relacorilant, are prohibited: – Adrenostatic medications: metyrapone, ketoconazole, fluconazole, aminoglutethimide, or etomidate 4 weeks before Day 1 through the end of this study – Neuromodulator drugs that act at the hypothalamic-pituitary level: serotonin antagonists (cyproheptadine, ketanserin, ritanserin), dopamine agonists (bromocriptine, cabergoline), gamma-aminobutyric acid agonists (sodium valproate), and somatostatin receptor ligands (octreotide long-acting release [LAR], pasireotide LAR, lanreotide) from 8 weeks before Day 1 through the end of this study. Use of short-acting somatostatin analogs (octreotide, pasireotide) from 4 weeks before Day 1 through the end of this study. • Mifepristone, from 4 weeks before Day 1. • Ongoing use of any strong CYP3A4 inhibitors (including grapefruit, grapefruit juice, or grapefruit-containing products) or inducers during treatment with relacorilant. • Mitotane, from 3 months prior to Day 1. • Ongoing use of antidiabetic, antihypertensive, antidepressant, and/or lipid-lowering medications that are highly dependent on CYP3A for clearance and that cannot undergo dose modifications upon coadministration with strong CYP3A inhibitors. 5. Plan to use systemic or potent (Group III) intra-articular corticosteroids from Day 1 through the end of the study. 6. Have received investigational treatment (drug, biological agent, or device) other than relacorilant within 4 weeks of study entry. 7. Have a history of an allergic reaction or intolerance to relacorilant. 8. Have uncorrected hypokalemia (potassium level of 1.5 × the ULN or elevated alanine aminotransferase (ALT) or aspartate aminotransferase (AST) =3 × ULN. 12. Have a clinically significant ECG abnormality at baseline, which, in the opinion of the Investigator, will make the patient an unsuitable candidate for the study. 13. Have a confirmed baseline QT interval corrected using Fridericia’s formula (QTcF) of >450 ms for males and >470 ms for females in the presence of a normal QRS interval (QRS 500 ms with a wide QRS interval (=120 ms),or a history of additional risk factors for torsades de pointes. 14. Female who is pregnant or lactating. 15. Have an ongoing SAE that started in the parent study.
