They act by blocking the action of the enzyme, aromatase, that is necessary for the production of estradiol. This class of drugs, aromatase inhibitors, are very effective in reducing estradiol levels in postmenopausal women and in treating estrogen receptor positive breast cancers. This study is examining the effect of a specific inhibitor, anastrozole, on endometrial thickness in premenopausal women. The endometrium is sensitive to estradiol and also has local aromatase which, if inhibited, may result in reduced endometrial thickness. The main hypothesis is that anastrozole can be administered at any time during the menstrual cycle and reduce endometrial thickness compared to placebo.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT'], 'maximumAge': '45 Years', 'minimumAge': '25 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Between the ages of 25 and 45 and pre-menopausal;\n* Non-lactating and not pregnant\n* able to follow the schedule of procedures\n* able to freely provide informed consent\n* have clinically acceptable physical examination and safety laboratory studies\n\nExclusion Criteria:\n\n* current use of any form of systemic contraceptive\n* have self-reported irregular menstrual cycles\n* intercurrent illness(es) detected on the screening physical\n* unwilling or unable to use barrier methods of contraception\n* have evidence of endometrial polyps or myomata on TVU/SIS that would interfere with endometrial thickness measurement\n* detection of ovarian cyst(s) during adnexal examination on screening TVU/SIS measuring greater than 5 cm\n* have history of, or current cancer, on any form exclusive of basal cell carcinoma\n* BMI \\>= 35\n* history of alcohol or drug abuse in the past 5 years\n* unwilling or unable to undergo study procedures within the necessary time frames\n* history or current liver abnormalities as defined by ALT or AST \\> 2X ULN\n* treated or untreated diabetes defined as fasting blood sugar \\>= 126 mg/dL\n* untreated hypertension\n* impaired renal function by estimated creatinine clearance \\< 80mL/min\n* have estradiol levels \\< 20 pg/ml and FSH levels \\> 40 mIU/mL or\n* have a history of adverse reaction any aromatase inhibitor'}, 'identificationModule': {'nctId': 'NCT00467493', 'briefTitle': 'Partial Double-Blind, Placebo-Controlled Study to Assess the Effect of Anastrozole on the Endometrium in Healthy Volunteers', 'organization': {'class': 'INDUSTRY', 'fullName': 'Meditrina Pharmaceuticals'}, 'officialTitle': 'A Partial Double-Blind, Placebo-Controlled Study to Assess the Efficacy and Safety of Anastrozole, an Aromatase Inhibitor, on Endometrial Thickness in Healthy Premenopausal Women When Dosed at Various Times During the Menstrual Cycle (Protocol M-001)', 'orgStudyIdInfo': {'id': 'M-001'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Anastrozole - A', 'description': 'Treatment for 26 consecutive days', 'interventionNames': ['Drug: Anastrozole']}, {'type': 'EXPERIMENTAL', 'label': 'Anastrozole -B', 'description': 'Treatment for 7 consecutive days early in menstrual cycle', 'interventionNames': ['Drug: Anastrozole']}, {'type': 'EXPERIMENTAL', 'label': 'Anastrozoe - C', 'description': 'Treatment for 7 consecutive days mid follicular phase', 'interventionNames': ['Drug: Anastrozole']}, {'type': 'EXPERIMENTAL', 'label': 'Anastrozole - D', 'description': 'Treatment for 7 consecutive days - mid cycle', 'interventionNames': ['Drug: Anastrozole']}, {'type': 'EXPERIMENTAL', 'label': 'Anastrozole - E', 'description': 'Treatment for 7 consecutive days - luteal', 'interventionNames': ['Drug: Anastrozole']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Anastrozole - F', 'description': 'Treatment with placebo for 26 consecutive days', 'interventionNames': ['Drug: Anastrozole']}], 'interventions': [{'name': 'Anastrozole', 'type': 'DRUG', 'armGroupLabels': ['Anastrozoe - C', 'Anastrozole - A', 'Anastrozole - D', 'Anastrozole - E', 'Anastrozole - F', 'Anastrozole -B']}]}, 'contactsLocationsModule': {'locations': [{'zip': '49007', 'city': 'Kalamazoo', 'state': 'Michigan', 'country': 'United States', 'facility': 'Jasper Research Clinic', 'geoPoint': {'lat': 42.29171, 'lon': -85.58723}}, {'zip': '48034', 'city': 'Southfield', 'state': 'Michigan', 'country': 'United States', 'facility': "University Women's Care", 'geoPoint': {'lat': 42.47337, 'lon': -83.22187}}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Meditrina Pharmaceuticals', 'class': 'INDUSTRY'}}}}
