Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   44338   clinical trials with a EudraCT protocol, of which   7368   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Not applicable
    E.2.3Trial contains a sub-study No
    E.3Principal 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.

    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 6 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. For patients entering the study >12 weeks after completing the last dose in the parent study, confirmation of hypercortisolism consistent with the criteria of the parent study is required.
    9. For patients who received treatment for hypercortisolism after their last dose in the parent study, confirmation of hypercortisolism consistent with the criteria of the parent study is required.
    E.4Principal 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 or has known active COVID-19 infection at Screening.
    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, osilodrostat, 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.
    • Patients who require inhaled glucocorticoid use and have no alternative option if their condition deteriorates during the study.
    • Mifepristone, from 4 weeks before Day 1.
    • Ongoing use of any strong CYP3A inducers during treatment with relacorilant.
    • Has used mitotane 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. Plans for prolonged regular use of systemic glucocorticoids 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, or within 5 times the drug’s half-life, whichever is longer.
    7. Have a history of an allergic reaction or intolerance to relacorilant.
    8. Have uncorrected clinically significant hypokalemia (potassium level of < 3 mEq/L) within 2 weeks before enrollment in this study (Day 1).

    10. Have renal failure as defined by a serum creatinine of ≥2.2 mg/dL.
    11. Have elevated total bilirubin >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 <120 ms), a QTcF interval >500 ms with a wide QRS interval (≥120 ms),or a history of additional risk factors for torsades de pointes.
    14. Has received stereotactic radiation therapy for a Cushing syndrome-related tumor within 24 months of Baseline or conventional pituitary radiation therapy within 36 months of Baseline.
    15. Has undergone pituitary surgery <3 months prior to Screening.
