Exposure-based cognitive-behavioral therapy (CBT) is a first-line treatment, but clinically significant change is only seen in approx. 50-65% of patients. Patient stratification is a powerful option to increase treatment response; however, developing prognostic markers suitable for single-patient predictions still is in its infancy and crucially requires external cross-validation embedded within an a priori prediction approach - a procedure yet largely missing in the field of biomarker research. Employing a bicentric strategy the aim of this study is to test the hypothesis that a priori prediction of treatment outcome based on neurobiological measures is possible in a second, independent sample. Building upon findings from previous mechanistic studies, These will be incorporated into the development of a predictive pattern comprising fear-relevant genotypes and molecules targeting neuropeptides, related epigenetic signatures as well as neurofunctional activation patterns associated with fear circuitry functions, and clinical data. Pre-treatment neurobiological signatures will be tested for their potential as a predictive response marker towards behavioral exposure (virtual reality exposure treatment (VRET) and an in vivo behavioral avoidance test) in a model disorder of fear circuitry dysfunctions (spider phobia). Multivariate pattern analyses employing a machine learning framework will be used to generate predictions on the individual patient level and to cross-validate markers in a second, independent sample. While at site A predictions will be generated following completion of the treatment, response will be predicted at site B a priori, but in a double-blind manner. Comparison of observed vs. predicted response rates will serve as a test of hypothesis. In addition, neuroplastic (on a subsample) and epigenetic changes induced by VRET treatment will be assessed following treatment and, in case of epigenetics, also after 6-months follow-up.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 18 or older\n* specific phobia (animal subtype: spider phobia) according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, 5th Version (DSM-5)\n* right-handedness\n* Caucasian descent\n* willingness to participate in massed exposure\n\nExclusion Criteria:\n\n* patients exhibiting a primary other anxiety disorder (panic disorder, agoraphobia, social phobia, generalized anxiety disorder), acute suicidality, psychotic, bipolar I, obsessive-compulsive disorder, posttraumatic stress disorder, severe major depression, borderline personality disorder or substance dependency (except nicotine)\n* patients fulfilling MRI-related exclusion criteria\n* patients with current pharmacological or psychotherapeutic treatment, as well as those already previously treated with exposure-based CBT\n* pregnancy or lactation'}, 'identificationModule': {'nctId': 'NCT03208400', 'briefTitle': 'Virtual Reality Exposure in Spider Phobia', 'organization': {'class': 'OTHER', 'fullName': 'Julius-Maximilians University'}, 'officialTitle': 'Exposure Treatment in Anxiety Disorders: Proof of Principle for an a Priori Response Prediction Approach', 'orgStudyIdInfo': {'id': 'Spider_VR'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'OTHER', 'label': 'virtual reality exposure', 'description': 'one-session exposure conveyed via virtual reality technology', 'interventionNames': ['Behavioral: virtual reality exposure']}], 'interventions': [{'name': 'virtual reality exposure', 'type': 'BEHAVIORAL', 'description': 'one-session exposure conveyed via virtual reality technology', 'armGroupLabels': ['virtual reality exposure']}]}, 'contactsLocationsModule': {'locations': [{'zip': '97080', 'city': 'Würzburg', 'state': 'Bavaria', 'country': 'Germany', 'facility': 'Center of Mental Health, Dept. of Psychiatry, Psychosomatics, and Psychiatry, University Hospital of Wuerzburg', 'geoPoint': {'lat': 49.79391, 'lon': 9.95121}}, {'zip': '48149', 'city': 'Münster', 'state': 'North Rhine-Westphalia', 'country': 'Germany', 'facility': 'Dept. of Psychiatry, University Hospital Münster', 'geoPoint': {'lat': 51.96236, 'lon': 7.62571}}], 'overallOfficials': [{'name': 'Ulrike Lueken, Prof. Dr.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University Hospital of Wuerzburg'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Julius-Maximilians University', 'class': 'OTHER'}, 'collaborators': [{'name': 'University Hospital Muenster', 'class': 'OTHER'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Prof. Dr.', 'investigatorFullName': 'Ulrike Lueken', 'investigatorAffiliation': 'Julius-Maximilians University'}}}}
