A therapy that lowers the risk of arterial and venous thrombosis would seem to be a reasonable approach to managing this disease, for which there is currently no treatment.\n\nATORVO is a randomized double-masked clinical trial comparing a daily dose of 80 mg of atorvastatin to matched placebo in persons recently diagnosed with RVO. At 24 weeks after randomization, we will evaluate each participant's visual acuity and the presence of secondary complications related to RVO."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '40 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Adults aged 40 years and older\n* Diagnosed with CRVO or BRVO\n* Visual acuity of 20/40 or worse in the affected eye\n* Onset of current symptoms of loss of vision within the past 60 days\n* Ability to understand spoken English\n\nExclusion Criteria:\n\n* Current use of a statin or fibrate medication\n* Known cardiovascular disease or revascularization, including coronary artery disease (myocardial infarction or angina), stroke or peripheral artery occlusion\n* Known diabetes mellitus\n* Known liver disease\n* Serum low-density lipoprotein cholesterol (LDL-C) \\> 5.0 mmol/L\n* Baseline serum triglycerides \\> 6.0 mmol/L\n* Serum ALT above 115 U/L (i.e., 2.5 x upper limit of normal)\n* Baseline serum creatinine \\> 250 µmol/L\n* Ocular surgery within the past 90 days\n* Planned ocular or cataract surgery within the study period\n* Known retinal disease: age-related macular degeneration, retinal detachment or macular hole, or past history of vein occlusion\n* Women who are pregnant or who are breastfeeding\n* Participation in another clinical trial concurrently or within 30 days prior to screening\n* Known allergy to fluorescein dye\n* Current use of cyclosporine medication.\n* Current use of an HIV protease inhibitor medication.'}, 'identificationModule': {'nctId': 'NCT00517257', 'acronym': 'ATORVO', 'briefTitle': 'Atorvastatin for the Treatment of Retinal Vein Occlusion', 'organization': {'class': 'OTHER', 'fullName': 'University of Toronto'}, 'officialTitle': 'Atorvastatin Toronto Retinal Vein Occlusion Study (ATORVO)', 'orgStudyIdInfo': {'id': 'NRA2580025'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'A', 'description': 'Atorvastatin 80 mg orally once daily for 24 weeks', 'interventionNames': ['Drug: Atorvastatin']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'P', 'description': 'Placebo tablet orally once daily for 24 weeks', 'interventionNames': ['Drug: Placebo']}], 'interventions': [{'name': 'Atorvastatin', 'type': 'DRUG', 'otherNames': ['Lipitor'], 'description': '80 mg orally once daily for 24 weeks', 'armGroupLabels': ['A']}, {'name': 'Placebo', 'type': 'DRUG', 'description': 'Placebo tablet orally once daily for 24 weeks', 'armGroupLabels': ['P']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'M5B 1W8', 'city': 'Toronto', 'state': 'Ontario', 'status': 'RECRUITING', 'country': 'Canada', 'contacts': [{'name': 'Brigita Zile, RN CCRP', 'role': 'CONTACT', 'email': 'zileb@smh.toronto.on.ca', 'phone': '416-864-6060', 'phoneExt': '4130'}, {'name': 'Joel G Ray, MD MSc', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'David T Wong, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Larry Leiter, MD', 'role': 'SUB_INVESTIGATOR'}, {'name': 'Shaun Goodman, MD MSc', 'role': 'SUB_INVESTIGATOR'}, {'name': 'Anatoly Langer, MD', 'role': 'SUB_INVESTIGATOR'}], 'facility': "St. Michael's Hospital", 'geoPoint': {'lat': 43.70643, 'lon': -79.39864}}], 'centralContacts': [{'name': 'Brigita Zile Zile, RN', 'role': 'CONTACT', 'email': 'zileb@smh.toronto.on.ca', 'phone': '416-864-6060', 'phoneExt': '4130'}, {'name': 'Joel Ray, MD MSc', 'role': 'CONTACT', 'email': 'rayj@smh.toronto.on.ca', 'phone': '416-864-6060', 'phoneExt': '6752'}], 'overallOfficials': [{'name': 'Joel G Ray, MD MSc', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': "St. Michael's Hospital, University of Toronto"}, {'name': 'David Wong, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': "St. Michael's Hospital, University of Toronto"}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Toronto', 'class': 'OTHER'}, 'collaborators': [{'name': 'Unity Health Toronto', 'class': 'OTHER'}, {'name': 'Pfizer', 'class': 'INDUSTRY'}, {'name': 'Canadian Heart Research Centre', 'class': 'OTHER'}, {'name': 'Ontario Association of Optometrists', 'class': 'OTHER'}, {'name': 'Toronto Ophthalmological Society', 'class': 'UNKNOWN'}]}}}
