A reliable continuous glucose signal could help to observe levels of glycaemia not only at defined time-points but continuously, making it possible for physicians and nursing staff to better adjust antihyperglycemic therapy and to react before the patient is exposed to severe hypo- or hyperglycaemia.\n\nIn the hospital setting, vascular access is granted in the majority of patients and could as well be used as an alternative site for continuous glucose monitoring.\n\nThe aim of the present study is to assess accuracy of the glucose data obtained by means of an intravascular microdialysis-based CGM system against venous blood glucose reference measurements.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Subjects with type 1 diabetes', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Informed consent obtained after being advised of the nature of the study\n* Male or female aged 18 - 75 years (both inclusive)\n* Type 1 diabetes treated with multiple daily insulin injection or continuous subcutaneous insulin infusion for 12 months\n* Body mass index 20.0 - 29.5 kg/m² (both inclusive)\n* HbA1c \\< 86.0mmol/mol\n\nExclusion Criteria:\n\n* Female of childbearing potential who is pregnant, breast-feeding or intend to become pregnant or is not using adequate contraceptive methods.\n* Skin pathology or condition prohibiting needle insertion as judged by the investigator.\n* History of bleeding disorder.\n* History of heparin-induced thrombocytopenia (HIT)\n* Current participation in another clinical study.\n* Significant acute or chronic illness that might interfere with subject safety or integrity of results as judged by the investigator.\n* Lipodystrophy\n* Current treatment with systemic (oral or i.v.) corticosteroids or any anticoagulation medication.\n* Blood donation or blood loss of more than 500 mL within 12 weeks prior to the study day.\n* Known hypersensitivity to Fondaparinux sodium (Arixtra®).\n* Significant history of alcoholism or drug abuse or a positive result in urine drug/alcohol screen.\n\nStudy day exclusion criteria:\n\n* Non-fasting (i.e. consumption of food or beverages, other than water, later than 22:00 hours the evening before the visit) except if slight intake of rapidly absorbable carbohydrates has been necessary in order to prevent hypoglycaemia.\n* Positive result of alcohol breath test.'}, 'identificationModule': {'nctId': 'NCT01709851', 'briefTitle': 'Performance Study to Test the GlucoMen®Day System Using Intravascular and Subcutaneous Microdialysis in Subjects With Type 1 Diabetes', 'organization': {'class': 'OTHER', 'fullName': 'Medical University of Graz'}, 'officialTitle': 'A Single-center, Open, Pilot Trial to Investigate the Performance of the GlucoMen®Day System Using Intravascular and Subcutaneous Microdialysis in Subjects With Type 1 Diabetes', 'orgStudyIdInfo': {'id': 'GMD_05'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Type 1 Diabetes - vMD and sMD', 'description': 'Patients will undergo vascular (vMD) and subcutaneous microdialysis (sMD) using the GMD-system (GlucoMen(R)Day-system)', 'interventionNames': ['Device: Vascular and subcutaneous microdialysis using the GMD-system']}, {'label': 'Type 1 diabetes - vMD', 'description': 'Patients will undergo vascular microdialysis (vMD) using the GMD-system (GlucoMen(R)Day-system)', 'interventionNames': ['Device: Vascular microdialysis using the GMD-system']}], 'interventions': [{'name': 'Vascular microdialysis using the GMD-system', 'type': 'DEVICE', 'description': 'Glucose levels will be monitored by means of vascular microdialysis using the GlucoMen(R)Day system', 'armGroupLabels': ['Type 1 diabetes - vMD']}, {'name': 'Vascular and subcutaneous microdialysis using the GMD-system', 'type': 'DEVICE', 'description': 'Glucose levels will be monitored by means of vascular and subcutaneous microdialysis using the GlucoMen(R)Day system', 'armGroupLabels': ['Type 1 Diabetes - vMD and sMD']}]}, 'contactsLocationsModule': {'locations': [{'zip': '8036', 'city': 'Graz', 'country': 'Austria', 'facility': 'Medical University of Graz, Dept. of Internal Medicine, Endocrinology and Metabolism', 'geoPoint': {'lat': 47.06733, 'lon': 15.44197}}], 'overallOfficials': [{'name': 'Thomas R.
