GLP-1 has convincing effects on the high glucose levels in type 2 diabetic patients and is well tolerated. New animal studies indicate a protective effect of GLP-1 in the brain and the heart. The mechanism behind this is yet not known.\n\nThe study hypothesis is that GLP-1 will stimulate glucose-uptake in the brain and heart independent of insulin and thereby exert its protective effects.', 'detailedDescription': 'Type 2 diabetes mellitus, T2D is a disease characterized by an immense growing prevalence world wide. T2D is associated with a three-fold increase in cardiovascular complications (myocardial infarction and stroke) leading to significantly higher morbidity and mortality in this group of patients. The prospective British Diabetes Study (UKPDS) showed that neither diet alone nor the pharmaceutical treatment utilized (Sulphonylurea, Metformin, Insulin) were able to reduce these macrovascular complications. GLP-1 (glucagon-like-peptide-1)is an incretin with convincing effects on glycaemia in type 2 diabetic patients with little or no risk of hypoglycaemia. New research in animal models has shown a potential protective effect in the brain and heart in association with ischaemic damage. The mechanism behind this protective effect is not known.\n\nThe effect of native GLP-1 on glucose uptake in the brain and heart will by visualized by fluoro-deoxy-glucose FDG-PET-scan during normoglycaemia in healthy young men. At the same time a pancreatic/pituitary clamp will be performed. The hypothesis is that GLP-1 directly will stimulate glucose uptake independent of the pancreatic hormones and through this mechanism exert its neuro- and cardioprotective actions.\n\nComparisons: FDG-uptake in the brain and heart with GLP-1 infusion compared to placebo.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '50 Years', 'minimumAge': '20 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Healthy men\n* Age 20-50 years\n* Caucasian\n* BMI 20-30 kg/m2\n\nExclusion Criteria:\n\n* Diabetes in subject and 1.degree relatives\n* Any disease of clinical relevance'}, 'identificationModule': {'nctId': 'NCT00256256', 'briefTitle': 'The Effect of GLP-1 on Glucose Uptake in the Brain and Heart in Healthy Men', 'organization': {'class': 'OTHER', 'fullName': 'University of Aarhus'}, 'officialTitle': 'The Effect of GLP-1 on Glucose Uptake in the CNS and Heart in Healthy Subjects During Normoglycaemia Assessed by Positron Emission Tomografi', 'orgStudyIdInfo': {'id': '2005-0079'}}, 'armsInterventionsModule': {'interventions': [{'name': 'glucagon-like-peptide-1', 'type': 'DRUG', 'description': 'Dose: 1.2pmol/kg/min for 6 hours'}]}, 'contactsLocationsModule': {'locations': [{'zip': '8000', 'city': 'Aarhus', 'country': 'Denmark', 'facility': 'Department of pharmacology, Aarhus university', 'geoPoint': {'lat': 56.15674, 'lon': 10.21076}}], 'overallOfficials': [{'name': 'Ole Schmitz, MD,professor', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Department of pharmacology, Aarhus university'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Aarhus', 'class': 'OTHER'}}}}
