It is not approved in the USA for the treatment of MACS. It is approved in Europe for the treatment of ACTH dependent Cushing's Syndrome.\n\nMetyrapone is currently being tested to evaluate the safety (side effects/risks) and efficacy (benefits), so its use for the treatment of MACS is experimental in the USA. Its effectiveness is unproven in the USA and metyrapone is considered an investigational study drug in the USA. The Mayo Clinic IRB has given approval for this drug to be used in this setting.\n\nPatients diagnosed with MACS have abnormal cortisol levels above the normal range. Cortisol acts by binding with the cortisol receptors in many tissues of the body. Metyrapone works by reducing cortisol production, thereby decreasing the effects of too much cortisol. Metyrapone doesn't affect levels of other hormones in your body."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Provide written informed consent.\n* Stated willingness to comply with all study procedures and availability for the duration of the study.\n* Diagnosed with MACS: at least 2 abnormal post-dexamethasone cortisol results (1 mg post-dexamethasone cortisol \\> 1.8 mcg/d; or 8 mg post-dexamethasone cortisol \\> 1 mcg/dL) and historical dexamethasone suppression test results can be used if performed within 24 months prior to enrollment.\n* Adrenal imaging phenotype consistent with benign disease (adrenal adenoma/s, macronodular or micronodular adrenal hyperplasia).\n* At least one of the following comorbidities: obesity (BMI \\> 30 kg/m\\^2); dysglycemia; dyslipidemia; hypertension; osteopenia; osteoporosis; fragility fractures.\n* Ability to take oral medication and be willing to adhere to the study intervention regimen.\n* For females of reproductive potential: use of highly effective contraception initiated prior to baseline visit and for 1 month after completing metyrapone study.\n* For persons of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of \\<5% per year during the treatment period and for 6 months after the last dose of study treatment.\n* Stable timing for bedtime for at least one week prior to on-site study visits\n\nExclusion Criteria:\n\n* Planned alternative therapy for MACS within 6 months after joining the study.\n* Current use of oral exogenous glucocorticoid therapy.\n* Current use of opioid therapy \\> 20 MME/day.\n* Planned use of oral exogenous glucocorticoid therapy.\n* Planned use of opioid therapy \\> 20 MME/day.\n* Use of injectable glucocorticoid within the last 6 weeks.\n* Investigator's judgement based on history/physical examination that a comorbidity or concomitant medication may impact the hypothalamic-pituitary-adrenal axis or steroid metabolome.\n* Uncontrolled intercurrent illness including, but not limited to: ongoing or active infection; symptomatic congestive heart failure; unstable angina pectoris; cardiac arrhythmia; psychiatric illness/social situations that would limit compliance with study requirements.\n* Pregnancy or lactation.\n* Known allergic reactions to metyrapone.\n* Suspected false positive post-dexamethasone cortisol results due to increased metabolism, poor absorption, or noncompliance with dexamethasone.\n* Treatment with another investigational drug or other intervention within lower than specific therapy washout period."}, 'identificationModule': {'nctId': 'NCT06106295', 'briefTitle': 'Metyrapone for Mild Autonomous Cortisol Secretion (MACS)', 'organization': {'class': 'OTHER', 'fullName': 'Mayo Clinic'}, 'officialTitle': 'Metyrapone Intervention in Patients With Mild Autonomous Cortisol Secretion (MACS)', 'orgStudyIdInfo': {'id': '23-008085'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Mild Autonomous Cortisol Secretion (MACS) Open Label Phase and Optional Extension Phase', 'description': 'Subjects diagnosed with Mild Autonomous Cortisol Secretion (MACS) will receive metyrapone for a 6 month treatment period (Open Label Phase) with the option to continue for an additional 30 months of metyrapone therapy.
