Aim 1 will determine during sham repetitive transcranial magnetic stimulation (rTMS) how a drug stressor combination (yohimbine + hydrocortisone) relative to placebo alters : (1a) impulsivity; (1b) mood; and (1c) physiology. Aim 2 will determine whether active rTMS over the medial prefrontal cortex alters the effects of stress-exposure on (2a) decision-making, (2b) mood, and (2c) biomarkers of stress.', 'detailedDescription': 'This study will use a double-blind, within-subjects randomized crossover design. Each participant will complete 4 sessions in this two-factor (2x2) combinatorial design: 1Hz medial prefrontal cortex (mPFC) vs. sham repetitive transcranial magnetic stimulation (rTMS) X pharmacological stressor (yohimbine 54mg + hydrocortisone 20mg) vs. placebo, with each session separated by at least 1 week. Participants will be asked not to use alcohol or drugs for 24-hr before arriving at the lab. We expect to complete screen at least 20 individuals to complete 12 individuals in this study. Candidates will first undergo psychiatric and medical screening to rule out contraindications to participation. Once enrolled, each participant will complete, in randomized order, the 4 conditions above. Periodic measures will be collected before and after the rTMS/sham and stress/placebo interventions. These measures will include subjective, behavioral and physiological assessments, as well as saliva and blood samples.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '60 Years', 'minimumAge': '21 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age 21-60 yr\n* Right-handed\n* Males and non-pregnant/non-lactating females\n* Cognitively intact (total IQ score \\>80 on Shipley Institute of Living Scale)\n* Screening cardiovascular indices must be within ranges that allow for safe use of stressor: resting HR 50-90 bpm, systolic BP 90-140 mmHg, and diastolic BP 50-90 mmHg\n* Use alcohol and/or marijuana \\<3 times/week; each "time" should consist of \\<1 marijuana "joint" equivalent and \\<3 alcoholic drinks\n\nExclusion Criteria:\n\n* Under influence of any substance during session\n* Past 7-day use of illicit drugs (excluding marijuana) based on Timeline Followback interview\n* Urine positive for opioids, cocaine metabolites, benzodiazepines, barbiturates, amphetamines or pregnancy\n* Medical conditions prohibiting use of rTMS (e.g. seizure history; using validated rTMS screening instrument)\n* Lifetime diagnosis of: psychotic disorder, bipolar disorder, generalized anxiety disorder, obsessive compulsive disorder, or major depression that is not substance-induced\n* Past-year substance use disorder\n* Medical conditions making it unsafe for participation (e.g. neurological, cardiovascular, pulmonary, or systemic diseases)\n* Lactose intolerance (placebo dose)\n* Any prohibited medications: medications that lower seizure threshold, psychiatric medications, prescription pain medications, or blood pressure medications\n* Chronic head or neck pain\n* Taken part in any research studies in the past month'}, 'identificationModule': {'nctId': 'NCT04180969', 'acronym': 'TSM-1', 'briefTitle': 'rTMS of Limbic Circuitry in Stress Modulation in Healthy Volunteers', 'organization': {'class': 'OTHER', 'fullName': 'Wayne State University'}, 'officialTitle': 'Impact of Repetitive Transcranial Magnetic Stimulation (rTMS) of Limbic Brain Circuitry in Stress Modulation in a Healthy Population', 'orgStudyIdInfo': {'id': 'TSM-1'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'PLACEBO_COMPARATOR', 'label': 'placebo stressor, sham rTMS', 'description': 'placebo stressor is lactose, and sham rTMS is inactive figure of 8 coil', 'interventionNames': ['Drug: Placebo oral tablet', 'Device: sham rTMS']}, {'type': 'EXPERIMENTAL', 'label': 'placebo stressor, active rTMS', 'description': 'placebo stressor is lactose, and active rTMS is 1Hz stimulation over the medial prefrontal cortex', 'interventionNames': ['Device: medial prefrontal cortex rTMS', 'Drug: Placebo oral tablet']}, {'type': 'EXPERIMENTAL', 'label': 'active stress, sham rTMS', 'description': 'active stressor is the combination of yohimbine 54mg + hydrocortisone 20mg, and sham rTMS is inactive figure of 8 coil', 'interventionNames': ['Drug: yohimbine + hydrocortisone', 'Device: sham rTMS']}, {'type': 'EXPERIMENTAL', 'label': 'active stress, active rTMS', 'description': 'active stressor is the combination of yohimbine 54mg + hydrocortisone 20mg, and active rTMS is 1Hz stimulation over the medial prefrontal cortex', 'interventionNames': ['Drug: yohimbine + hydrocortisone', 'Device: medial prefrontal cortex rTMS']}], 'interventions': [{'name': 'yohimbine + hydrocortisone', 'type': 'DRUG', 'description': 'yohimbine 54mg + hydrocortisone 20mg oral', 'armGroupLabels': ['active stress, active rTMS', 'active stress, sham rTMS']}, {'name': 'medial prefrontal cortex rTMS', 'type': 'DEVICE', 'description': '1 Hz mPFC rTMS', 'armGroupLabels': ['active stress, active rTMS', 'placebo stressor, active rTMS']}, {'name': 'Placebo oral tablet', 'type': 'DRUG', 'description': 'placebo stressor', 'armGroupLabels': ['placebo stressor, active rTMS', 'placebo stressor, sham rTMS']}, {'name': 'sham rTMS', 'type': 'DEVICE', 'description': 'sham mPFC rTMS', 'armGroupLabels': ['active stress, sham rTMS', 'placebo stressor, sham rTMS']}]}, 'contactsLocationsModule': {'overallOfficials': [{'name': 'Mark K Greenwald, PhD', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Wayne State University'}]}, 'ipdSharingStatementModule': {'infoTypes': ['STUDY_PROTOCOL'], 'timeFrame': 'Materials will only become available after the study is completed and the first manuscript from this project is published.', 'ipdSharing': 'YES', 'description': 'Full sharing plan is being developed.', 'accessCriteria': 'Qualified investigators may apply in writing to Dr. Greenwald'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Wayne State University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Professor', 'investigatorFullName': 'Mark Greenwald, PhD', 'investigatorAffiliation': 'Wayne State University'}}}}
