Capsules containing Berberine (BB, Berberine MetX™, 500 mg) - (reference product).', 'detailedDescription': "Study Background\n\nA growing body of evidence suggests that gamma-cyclodextrin (GCD) can increase the clinical efficacy of water-insoluble biologically active compounds with low bioavailability. GCD is the most bio adaptable and helpful to increase the absorption of many drugs, including Berberine from Indian Barberry (Berberis aristate DC.) Bark and Root Extract by forming inclusion complexes or GCD/drug conjugates.\n\nBerberine has been recommended in traditional practice and recognized by modern science to support healthy blood sugar†, cholesterol and triglyceride levels, and overall metabolic health. But despite these findings, standard Berberine can still be difficult for the body to absorb and use effectively.\n\nIt's estimated that only about five percent of any given dosage of Berberine makes it into the bloodstream, so finding a way to enhance absorption is key to the full advantage of its benefits.\n\nHypothesis: gamma-cyclodextrin increases absorption and bioavailability of Berberine from Berberine MetX™ Ultra Absorption capsules.\n\nThe study aims to provide experimental evidence supporting or rejecting this hypothesis.\n\nThis will be a double-blind, crossover design, pharmacokinetic study, where 16 healthy human volunteers will be randomly assigned to receive two different formulations BBA, and BB, in two consecutive phases of the study:\n\n* Phase A. All patients take capsules BBA., provide blood samples in 0.5, 0.75, 1, 2, 4, 6, 12, 24, and 48 hours (9 points) after administration following washout period for two weeks.\n* Phase B. All patients take capsules BB, provide blood samples in 0.5, 0.75, 1, 2, 4, 6, 12, 24, and 48 hours (9 points) after administration following washout period for two weeks.\n\nSubjects will be in the clinic from not less than 11 hours pre-dose to ensure at least 10 hours fasting before administering the investigational product. They will remain in the facility post-dose until at least 24 hours each period, provided they are not suffering from any adverse event.\n\nThe concentration of Berberine in all blood samples will be determined using a validated for a limit of detection, accuracy, and precision analytical method (HPLC-MS) with the internal standard - digoxin. Appropriate mathematical methods and Kinetic 4.4.1 software will be used to generate basic pharmacokinetic parameters."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '60 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Healthy volunteers, as determined by medical history, physical examination, and clinical laboratory testing,\n* Willingness to stay in the unit overnight for the duration of the study,\n* Provide a signed written informed consent.\n\nExclusion Criteria:\n\n* overweight (BMI \\>35 kg/m2),\n* pregnancy,\n* lactation,\n* drug abuse,\n* use of dietary supplements or any form of medication (with the exception of oral contraceptives),\n* heavy smokers, or ex-smokers with a remote history (\\> one pack/day),\n* frequent alcohol consumption (\\>20 g ethanol/d),\n* adherence to a restrictive dietary regimen,\n* physical activity of more than 5 h/wk,\n* respiratory tract infections, or suspicion thereof in the last 14 days before dosing,\n* history or presence of disease in the kidneys and heart, lungs, liver, gastrointestinal tract, endocrine organs or other conditions such as metabolic disease known to interfere with the absorption, distribution, metabolism, and excretion of drugs,\n* malignancy,\n* autoimmune disorders such as (but not limited to) lupus erythematosus, multiple sclerosis, rheumatoid arthritis, or sarcoidosis,\n* any other disease or condition, which, in the opinion of the Investigator, would make the subject unsuitable for this study,\n* currently taking medications known to be CYP2C9 inducers (i.e., carbamazepine and rifampicin).'}, 'identificationModule': {'nctId': 'NCT04918667', 'briefTitle': 'Effect of Gamma-cyclodextrin on the Bioavailability of Berberine', 'organization': {'class': 'INDUSTRY', 'fullName': 'EuroPharma, Inc.'}, 'officialTitle': 'A Phase I, Randomized, Crossover, Double-blind, Pharmacokinetic Study of Berberine Released From Cyclodextrin in Healthy Volunteers', 'orgStudyIdInfo': {'id': 'EP-1007'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Berberine MetX™ Ultra Absorption', 'description': '16 healthy subjects will receive orally 500 mg of berberine in two capsules of Berberine MetX™ Ultra Absorption.', 'interventionNames': ['Combination Product: Berberine incorporated in gamma cyclodextrin']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Berberine MetX™', 'description': '16 healthy subjects will receive orally 500 mg of berberine in one capsule of Berberine MetX™ (reference product).', 'interventionNames': ['Dietary Supplement: Berberine']}], 'interventions': [{'name': 'Berberine incorporated in gamma cyclodextrin', 'type': 'COMBINATION_PRODUCT', 'otherNames': ['Berberine MetX™ Ultra Absorption, 250 mg'], 'description': 'Experimental modified product.
