In Parkinson disease, low-range cortical Abeta plaque levels associate with serotonin terminal losses. Multicenter Parkinson disease observational findings show that selective serotonin reuptake inhibitors (SSRIs) associate with lower dementia conversion risk and different cerebrospinal fluid Abeta-42 levels. This study aims to test the hypothesis that citalopram use in Parkinson disease will reduce visuospatial cortex Abeta plaque accrual, leading to an amelioration of longitudinal visuospatial cognitive decline linked to Parkinsonian dementia. The study will test this hypothesis in a randomized placebo-controlled trial of citalopram 20mg daily over 26 months in Parkinson disease subjects (age ≥65) without depression (n=58).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['OLDER_ADULT'], 'minimumAge': '65 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Subjects with a Parkinson Disease (PD) diagnosis based on the United Kingdom Parkinson's Disease Society Brain Bank Research Center clinical diagnostic criteria\n* Modified Hoehn and Yahr (HY) scores spanning 2.0 to 3.0\n* Age 65 years or greater\n\nExclusion Criteria:\n\n* Diagnosis of an atypical parkinsonian condition\n* Participants on neuroleptics and participants with a history of use of anti-depressants (including selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), bupropion, St. John's Wort or other serotoninergic agents in the year preceding study enrollment\n* Evidence of a large artery stroke or mass lesion on brain imaging\n* Participants with a life threatening comorbid illness\n* Severe claustrophobia precluding PET imaging\n* Inability to participate in research procedures involving ionizing radiation\n* Pregnancy or breastfeeding\n* Participants with active depression as defined by a Geriatric Depression Scale score of \\>10 or on the basis of clinical diagnosis by the PI\n* Participants who report active suicidal ideation as defined by an affirmative answer to questions 1 and 2 on the C-SSRS\n* Participants with baseline HY scores \\<2.0 or ≥3.0\n* Participants with a QTc interval on baseline EKG \\>0.45 for men or \\>0.47 for women\n* Subjects taking certain contraindicated medications at baseline\n* Subjects unable to swallow pills\n* Subjects with a previous history of mania, ongoing hepatic impairment or epilepsy\n* Subjects with a known allergy to citalopram or escitalopram\n* Subjects with substantial cognitive impairment or dementia that would prevent them from providing informed consent\n* Subjects in another ongoing clinical trial\n* Subjects with treatment-naieve Parkinson disease"}, 'identificationModule': {'nctId': 'NCT04497168', 'briefTitle': 'Citalopram as a Posterior Cortical Protective Therapy in Parkinson Disease', 'organization': {'class': 'OTHER', 'fullName': 'University of Michigan'}, 'officialTitle': 'Citalopram as a Posterior Cortical Protective Therapy in Parkinson Disease', 'orgStudyIdInfo': {'id': 'HUM00146905'}, 'secondaryIdInfos': [{'id': '1R01AG065246', 'link': 'https://reporter.nih.gov/quickSearch/1R01AG065246', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Citalopram', 'description': '20mg daily', 'interventionNames': ['Drug: Citalopram 20mg']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'matching placebo pills', 'interventionNames': ['Drug: Placebo']}], 'interventions': [{'name': 'Citalopram 20mg', 'type': 'DRUG', 'description': '20mg daily', 'armGroupLabels': ['Citalopram']}, {'name': 'Placebo', 'type': 'DRUG', 'description': 'matching placebo pills', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'zip': '48109', 'city': 'Ann Arbor', 'state': 'Michigan', 'country': 'United States', 'facility': 'University of Michigan', 'geoPoint': {'lat': 42.27756, 'lon': -83.74088}}], 'overallOfficials': [{'name': 'Vikas Kotagal, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Michigan'}]}, 'ipdSharingStatementModule': {'url': 'https://www.openicpsr.org/openicpsr/', 'infoTypes': ['STUDY_PROTOCOL'], 'timeFrame': 'Consistent with NIA policies, the study team will ensure the dataset is shared by the occurrence of the earlier of the following two milestones: either the date of primary publication or within 9 months of lifting of the data lock.', 'ipdSharing': 'YES', 'description': 'Participant data will be uploaded in a timely manner in the "openICPSR" Data Management Resource (DMR) of ICPSR (Inter-University Consortium for Political and Social Research).
