Otherwise, women must be postmenopausal (at least one year absence of vaginal bleeding or spotting) as confirmed by FSH greater than or equal to 40 mIU/mL or 40 IU/L or be surgically sterile.\n * Men with a potentially fertile partner must have had a vasectomy or be willing to use an acceptable method of contraception for the duration of the study and for 3 months after study drug discontinuation.\n\nExclusion Criteria:\n\n* History of any significant neurologic or psychiatric disorder other than PD that can contribute to cognitive impairment.\n* Any other condition or clinically significant abnormal findings like severe co-morbidities e.g. history of stroke, poor kidney or liver function on the physical or neurological examination, medical and psychiatric history, at screening or at baseline that, in the opinion of the Investigator, would make the subject unsuitable for the study.\n* Potential symptomatic causes of cognitive impairment including but not limited to\n\n 1. abnormal thyroid function test at screening (TSH)\n 2. abnormal B12 level at screening\n 3. MRI findings (by history) pointing to a potential symptomatic cause of cognitive dysfunction, including significant vascular changes, or communicating hydrocephalus.\n* Treatment with memantine or amantadine. If appropriate the drugs can be discontinued for a minimum of 4 weeks prior to randomization.\n* Use of over the counter (OTC) or prescription medication for sleep on 2 or more occasions per week (less than that is allowed).\n* History of depression as measured by Beck Depression Inventory score \\>17 at screening.\n* Treatment with any other investigational drug or device within 4 weeks prior to screening.\n* Smoking \\> 1 pack of cigarettes per day (as assessed for the 4 weeks prior to screening).\n* Women who are pregnant or lactating.\n* Known allergy or sensitivity to ANAVEX2-73 or any of its components.\n* Suicidal ideation on the Columbia Suicide Severity Rating Scale (C-SSRS) of type 4 or type 5, or any suicidal behavior, in the past 6 months. Type 4 indicates active suicidal ideation with some intent to act, without a specific plan. Type 5 indicates active suicidal ideation with a specific plan and intent.\n* Use of centrally acting anticholinergic drugs during the 4 weeks before randomization.\n* Medications used for overactive bladder will be allowed provided that the regimen has been stable 4 weeks prior to randomization.\n* Treatment with any dopamine receptor blocking medications with the exception of low dose quetiapine (≤50 mg/day). Pimavanserin (≤34 mg/day) will be allowed.\n* History of neurosurgical intervention (e.g., deep brain stimulation) for PD.\n* Unpredictable motor fluctuations that would interfere with administering cognitive assessments in the ON state."}, 'identificationModule': {'nctId': 'NCT03774459', 'briefTitle': "ANAVEX2-73 Study in Parkinson's Disease Dementia", 'organization': {'class': 'INDUSTRY', 'fullName': 'Anavex Life Sciences Corp.'}, 'officialTitle': "A Phase 2, Double-Blind, Randomized, Placebo-Controlled Study to Evaluate the Safety, Tolerability, and Efficacy of ANAVEX2-73 for Cognitive Impairment in Patients With Parkinson's Disease With Dementia", 'orgStudyIdInfo': {'id': 'ANAVEX2-73-PDD-001'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'High dose ANAVEX2-73', 'description': 'High dose ANAVEX2-73', 'interventionNames': ['Drug: High dose ANAVEX2-73']}, {'type': 'EXPERIMENTAL', 'label': 'Mid dose ANAVEX2-73', 'description': 'Mid dose ANAVEX2-73', 'interventionNames': ['Drug: Mid dose ANAVEX2-73']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo oral capsule', 'description': 'Placebo oral capsule', 'interventionNames': ['Drug: Placebo oral capsule']}], 'interventions': [{'name': 'High dose ANAVEX2-73', 'type': 'DRUG', 'description': 'Active oral capsule', 'armGroupLabels': ['High dose ANAVEX2-73']}, {'name': 'Mid dose ANAVEX2-73', 'type': 'DRUG', 'description': 'Active oral capsule', 'armGroupLabels': ['Mid dose ANAVEX2-73']}, {'name': 'Placebo oral capsule', 'type': 'DRUG', 'description': 'Placebo oral capsule', 'armGroupLabels': ['Placebo oral capsule']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Macquarie Park', 'country': 'Australia', 'facility': 'KaRa MINDS', 'geoPoint': {'lat': -33.78105, 'lon': 151.12757}}, {'city': 'Malvern', 'country': 'Australia', 'facility': 'Hammond Health', 'geoPoint': {'lat': -37.86259, 'lon': 145.02811}}, {'city': 'Barakaldo', 'country': 'Spain', 'facility': 'Hospital Cruces Bilbao', 'geoPoint': {'lat': 43.29639, 'lon': -2.98813}}, {'city': 'Barcelona', 'country': 'Spain', 'facility': 'Hospital de la Santa Creu i Sant Pau', 'geoPoint': {'lat': 41.38879, 'lon': 2.15899}}, {'city': 'Barcelona', 'country': 'Spain', 'facility': 'Hospital Mutua Terrasa', 'geoPoint': {'lat': 41.38879, 'lon': 2.15899}}, {'city': 'Barcelona', 'country': 'Spain', 'facility': "Hospital Universitario Vall d'Hebron", 'geoPoint': {'lat': 41.38879, 'lon': 2.15899}}, {'city': 'Burgos', 'country': 'Spain', 'facility': 'Hospital Universitario de Burgos', 'geoPoint': {'lat': 42.34106, 'lon': -3.70184}}, {'city': 'Cadiz', 'country': 'Spain', 'facility': 'Hospital Universitario Puerta del Mar', 'geoPoint': {'lat': 36.52672, 'lon': -6.2891}}, {'city': 'Coslada', 'country': 'Spain', 'facility': 'Hospital del Henares', 'geoPoint': {'lat': 40.42378, 'lon': -3.56129}}, {'city': 'Elche', 'country': 'Spain', 'facility': 'Hospital General Universitario de Elche', 'geoPoint': {'lat': 38.26218, 'lon': -0.70107}}, {'city': 'Ferrol', 'country': 'Spain', 'facility': 'Hospital Arquitecto Marcide', 'geoPoint': {'lat': 43.48451, 'lon': -8.23293}}, {'city': 'Girona', 'country': 'Spain', 'facility': 'Hospital Santa Caterina', 'geoPoint': {'lat': 41.98311, 'lon': 2.82493}}, {'city': 'Madrid', 'country': 'Spain', 'facility': 'Clinica Ruber Internacional', 'geoPoint': {'lat': 40.4165, 'lon': -3.70256}}, {'city': 'Madrid', 'country': 'Spain', 'facility': 'Clínica Universidad de Navarra (CUN) -
