When a researcher injects SB-509 into your legs, the drug enters the muscle and nerve cells around the injection site and causes these cells to make a protein. This protein causes your cells to increase production of another protein called vascular endothelial growth factor (VEGF), which may improve the structure and function of nerves. In addition, there are changes in the levels of 28 additional proteins in your cells. These proteins function to promote the growth of cells, are structures in cells, help synthesize products, and affect immune cells, and some have unknown functions. This increase in your own VEGF proteins may protect and repair the damaged nerves caused by diabetic neuropathy.\n\nThe study doctor will test SB-509 (60 mg) and placebo. Everyone in this study will receive intramuscular (IM-directly into the muscle) injections into both legs. This will happen 3 times over about 4 months. Two out of every 3 participants will receive SB-509 and 1 out of every 3 will receive placebo. You will not know, and the study doctor will not know, whether you will receive SB-509 or whether you will receive placebo.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Key Inclusion Criteria:\n\n* Have a clinical diagnosis of diabetes mellitus type I or II for at least 12 months prior to the study.\n* Have received a diagnosis of mild to moderate sensorimotor diabetic neuropathy from a neurologist (a doctor who specializes in disorders of the nervous system) or endocrinologist (a doctor who specializes in diabetes). This type of neuropathy is a loss of sensation and muscle function that occurs in the legs and hands in a stocking and glove distribution. Subjects with diabetic neuropathy that results in loss of sensation or muscle function in only one nerve and results in loss of nerve function of the blood vessels and causes low blood pressure, will not be eligible.\n* If female and of childbearing potential, agree to use a medically acceptable physical barrier method during the study.\n* Have blood pressure \\< 140/90 mm Hg\n* Body mass index (BMI) \\< 38 kg/m2\n\nKey Exclusion Criteria:\n\nSubjects with the following are NOT eligible to participate in this study:\n\n* Have moderate to severe ischemic heart disease, any history of congestive heart failure, or have had a myocardial infarction (heart attack) within the previous 6 months.\n* Have chronic foot or leg ulcers for \\>1 month, gangrene in the legs, or any previous amputation of the lower extremity.\n* Have symptoms of intermittent claudication (or leg pain during exercise associated with peripheral artery disease) and/or an ankle brachial index (or a calculation of the difference between arm and leg blood pressures) of less than (\\<) 0.75.\n* Have a history of cancer within the past 5 years (except for curable non-melanoma cancer of the skin, superficial bladder cancer in complete remission, or any other cancer that has been in complete remission for at least 5 years).\n* Have colon polyps. If patients have a history of benign colonic polyps that have been removed, they must have evidence of a normal colonoscopy within the last 12 months.\n* Require any drug that depresses patients' immune systems (such as methotrexate, cyclophosphamide, or cyclosporine) when they receive the study drug and for 30 days afterwards.\n* Have a known disorder that affects patients' immune systems (such as HIV/AIDS, hepatitis B virus \\[HBV\\], hepatitis C virus \\[HCV\\], sarcoidosis, tuberculosis, rheumatoid arthritis, or autoimmune disorders)."}, 'identificationModule': {'nctId': 'NCT00406458', 'briefTitle': 'Clinical Trial of SB-509 in Subjects With Diabetic Neuropathy', 'organization': {'class': 'INDUSTRY', 'fullName': 'Sangamo Therapeutics'}, 'officialTitle': 'A Phase 2 Repeat Dosing Clinical Trial of SB-509 in Subjects With Diabetic Neuropathy', 'orgStudyIdInfo': {'id': 'SB-509-0601'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'SB-509', 'description': '60 mg SB-509 injected IM into lower limbs every 2 months', 'interventionNames': ['Drug: SB-509']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Normal Saline', 'description': 'Normal saline injected IM into lower limbs every 2 months', 'interventionNames': ['Other: Normal Saline']}], 'interventions': [{'name': 'SB-509', 'type': 'DRUG', 'description': '60 mg dose', 'armGroupLabels': ['SB-509']}, {'name': 'Normal Saline', 'type': 'OTHER', 'armGroupLabels': ['Normal Saline']}]}, 'contactsLocationsModule': {'locations': [{'zip': '92037', 'city': 'La Jolla', 'state': 'California', 'country': 'United States', 'facility': 'Coordinated Clinical Research', 'geoPoint': {'lat': 32.84727, 'lon': -117.2742}}, {'zip': '90712', 'city': 'Lakewood', 'state': 'California', 'country': 'United States', 'facility': 'Advanced Medical Research, LLC', 'geoPoint': {'lat': 33.85363, 'lon': -118.13396}}, {'zip': '94109', 'city': 'San Francisco', 'state': 'California', 'country': 'United States', 'facility': 'SF Clinical Research Center', 'geoPoint': {'lat': 37.77493, 'lon': -122.41942}}, {'zip': '94598', 'city': 'Walnut Creek', 'state': 'California', 'country': 'United States', 'facility': 'Diablo Clinical Research', 'geoPoint': {'lat': 37.90631, 'lon': -122.06496}}, {'zip': '34205', 'city': 'Bradenton', 'state': 'Florida', 'country': 'United States', 'facility': 'Bradenton Research Center', 'geoPoint': {'lat': 27.49893, 'lon': -82.57482}}, {'zip': '33136', 'city': 'Miami', 'state': 'Florida', 'country': 'United States', 'facility': 'University of Miami, Diabetes Research Institute', 'geoPoint': {'lat': 25.77427, 'lon': -80.19366}}, {'zip': '33351', 'city': 'Sunrise', 'state': 'Florida', 'country': 'United States', 'facility': 'Neurology Clinical Research', 'geoPoint': {'lat': 26.13397, 'lon': -80.1131}}, {'zip': '66160', 'city': 'Kansas City', 'state': 'Kansas', 'country': 'United States', 'facility': 'University of Kansas Medical Center', 'geoPoint': {'lat': 39.11417, 'lon': -94.62746}}, {'zip': '68131', 'city': 'Omaha', 'state': 'Nebraska', 'country': 'United States', 'facility': 'Creighton Diabetes Center', 'geoPoint': {'lat': 41.25626, 'lon': -95.94043}}, {'zip': '12205', 'city': 'Albany', 'state': 'New York', 'country': 'United States', 'facility': 'Upstate Clinical Research', 'geoPoint': {'lat': 42.65258, 'lon': -73.75623}}, {'zip': '10022', 'city': 'New York', 'state': 'New York', 'country': 'United States', 'facility': 'Peripheral Neuropathy Center, Weill Medical College of Cornell University', 'geoPoint': {'lat': 40.71427, 'lon': -74.00597}}, {'zip': '16635', 'city': 'Duncansville', 'state': 'Pennsylvania', 'country': 'United States', 'facility': 'Altoona Center for Clinical Research', 'geoPoint': {'lat': 40.42341, 'lon': -78.4339}}, {'zip': '77030', 'city': 'Houston', 'state': 'Texas', 'country': 'United States', 'facility': 'Nerve and Muscle Center of Texas', 'geoPoint': {'lat': 29.76328, 'lon': -95.36327}}, {'zip': '78229', 'city': 'San Antonio', 'state': 'Texas', 'country': 'United States', 'facility': 'DGD Research', 'geoPoint': {'lat': 29.42412, 'lon': -98.49363}}, {'zip': '06700', 'city': 'Mexico City', 'state': 'Col.
