It is an antagonist of the N-methyl-d-aspartate (NMDA) receptor, but former results indicate that its action also depends on the noradrenaline system and the locus coeruleus (LC).\n\nBased on this known impact of ketamine on the sympathetic nervous system the aim of this study is to investigate the effects of intranasal esketamine on LC related attentional brain networks in task based functional MRI, to relate those attention network changes to behavioural measures and to predict ketamine related attention network changes by brain structure.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* General health (no serious internal or neurologic pre-existing conditions) based on medical history, physical examination and structured clinical interview for DSM-IV (SCID)\n* Age 18 to 55 years\n* Right-handedness (due to potential lateralization effects of left-handed subjects)\n* Willingness and competence to sign the informed consent form\n\nExclusion Criteria:\n\n* Current or history of psychiatric or neurological disease\n* Current medical illness requiring treatment\n* Current or former substance abuse\n* Pregnancy or current breastfeeding\n* Diagnosis of an Axis-1 psychotic disorder in a first-degree relative\n* Known aneurysmal vascular disease based on medical history (including intracranial, thoracic, or abdominal aorta, or peripheral arterial vessels), history of intracerebral haemorrhage, recent (within 6weeks) cardiovascular event, including myocardial infarction (MI)\n* Significant pulmonary insufficiency, including COPD; sleep apnoea with morbid obesity (BMI ≥35), uncontrolled brady- or tachyarrhythmias that lead to haemodynamic instability; history of an MI, haemodynamically significant valvular heart disease or heart failure (NYHA Class III-IV)\n* Hyperthyroidism that has not been sufficiently treated\n* History of brain injury, hypertensive encephalopathy, intrathecal therapy with ventricular shunts, or any other condition associated with increased intracranial pressure\n* Child-Pugh class C (severe) hepatic impairment\n* Any contraindication for MRI (e.g., MR incompatible implants, etc.) including dental implants causing signal artifacts\n* Failure to comply with the study protocol or to follow the instruction of the investigating team'}, 'identificationModule': {'nctId': 'NCT05320120', 'briefTitle': 'Investigation of Intranasal Ketamine Related Changes in Attentional Brain Networks With Functional and Structural MRI', 'organization': {'class': 'OTHER', 'fullName': 'Medical University of Vienna'}, 'officialTitle': 'Investigation of Intranasal Ketamine Related Changes in Attentional Brain Networks With Functional and Structural MRI: a Placebo Controlled, Randomized, Cross-over Trial', 'orgStudyIdInfo': {'id': 'PSY-NIL-0011'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'first 56mg esketamine (2x Spravato® 28 mg nasal spray), then placebo', 'interventionNames': ['Drug: 56mg esketamine (2x Spravato® 28 mg nasal spray)', 'Drug: 0.9% saline solution nasal spray']}, {'type': 'EXPERIMENTAL', 'label': 'first placebo (0.9% saline solution nasal spray), then ketamine', 'interventionNames': ['Drug: 56mg esketamine (2x Spravato® 28 mg nasal spray)', 'Drug: 0.9% saline solution nasal spray']}], 'interventions': [{'name': '56mg esketamine (2x Spravato® 28 mg nasal spray)', 'type': 'DRUG', 'description': '56mg esketamine (2x Spravato® 28 mg nasal spray)', 'armGroupLabels': ['first 56mg esketamine (2x Spravato® 28 mg nasal spray), then placebo', 'first placebo (0.9% saline solution nasal spray), then ketamine']}, {'name': '0.9% saline solution nasal spray', 'type': 'DRUG', 'description': '0.9% saline solution nasal spray', 'armGroupLabels': ['first 56mg esketamine (2x Spravato® 28 mg nasal spray), then placebo', 'first placebo (0.9% saline solution nasal spray), then ketamine']}]}, 'contactsLocationsModule': {'locations': [{'zip': '1090', 'city': 'Vienna', 'country': 'Austria', 'facility': 'Department of Psychiatry and Psychotherapy', 'geoPoint': {'lat': 48.20849, 'lon': 16.37208}}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Rupert Lanzenberger', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR_INVESTIGATOR', 'investigatorTitle': 'Prof. Dr. Rupert Lanzenberger', 'investigatorFullName': 'Rupert Lanzenberger', 'investigatorAffiliation': 'Medical University of Vienna'}}}}
