Neuropathic pain is common and includes conditions such as diabetic neuropathy, post herpetic neuralgia and post stroke pain and is believed to affect at least 3% of adults. Surveys of patients with neuropathic pain indicate that 60% do not receive adequate relief with current treatment. Results from recent laboratory and human studies reveal a new approach to treatment. This approach is based on the findings that neuroinflammation appears to be involved in development and maintenance of neuropathic pain. This study explores the effects of an immune-modulating blood-derived product, intravenous immunoglobulin (IVIG), in treating neuropathic pain. IVIG is thought to reduce neuroinflammation contributing to neuropathic pain. If successful, the study will provide important insights into pain mechanisms and a better understanding of how IVIG relieves neuropathic pain.\n\nHypotheses:\n\n1. Reduction in neuroinflammation (NI) markers will co-vary with clinical indicators of pain relief\n2. Patients with higher levels of markers of NI will be more likely to respond to IVIG', 'detailedDescription': 'This study will employ a randomized double blind cross-over design. A total of 12 subjects will be recruited for the study. Once each subject has satisfied the inclusion and exclusion criteria and provided informed consent, the subject will be randomized to either the IVIG or placebo treatment groups, using a pre-determined randomization list generated by the research office at the University of Calgary. Complete responders will begin a monitoring phase, partial and non-responders will return for a second cycle in one month. Complete responders, with prolonged relief, will cross-over to the alternative treatment when their pain returns if this occurs within 6 months of the infusion.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Age \\>18 years; Clinical diagnosis of treatment-resistant neuropathic pain;\n* Score of 4/10 or greater on the DN4 NeP screening questionnaire;\n* Bedside examination confirming symptoms of neuropathic pain;\n* Moderate to severe pain;\n* Completed adequate analgesic trials according to neuropathic pain clinical practice guidelines;\n* provides informed consent\n\nExclusion Criteria:\n\n* Pregnant or lactating women;\n* Clinical diagnosis of phantom limb pain;\n* History of psychosis;\n* current, substance dependency disorder;\n* presence of clinically significant cardiac or pulmonary disorder that would compromise participants' safety;\n* severe pain disorder other than the chronic NeP under study;\n* Abnormalities above 1.5 times upper range of normal on screening CBC, blood chemistry;\n* Serum IgA less than \\<0.05 g/L"}, 'identificationModule': {'nctId': 'NCT00850005', 'briefTitle': 'Intravenous Immunoglobulin (IVIG) for Resistant Neuropathic Pain', 'organization': {'class': 'OTHER', 'fullName': 'University of Calgary'}, 'officialTitle': 'IVIG for Treatment of Resistant Neuropathic Pain: a Preliminary Study', 'orgStudyIdInfo': {'id': '200434'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'IVIG', 'description': 'Active treatment will be intravenous immunoglobulin G (Gamunex, immune globulin intravenous \\[human\\], 10%), at a dose of 2 g/kg divided over five days (0.4 g/kg/day).', 'interventionNames': ['Biological: Intravenous immunoglobulin']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'The placebo treatment will be intravenous normal saline and will be infused in a similar manner.', 'interventionNames': ['Biological: Normal Saline']}], 'interventions': [{'name': 'Intravenous immunoglobulin', 'type': 'BIOLOGICAL', 'description': '2 g/kg divided over five days', 'armGroupLabels': ['IVIG']}, {'name': 'Normal Saline', 'type': 'BIOLOGICAL', 'description': 'Same volume as experimental arm', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Calgary', 'state': 'Alberta', 'status': 'RECRUITING', 'country': 'Canada', 'contacts': [{'name': 'Alexander J Clark, MD', 'role': 'CONTACT', 'phone': '403 943 9917'}, {'name': 'Patricia Muehler', 'role': 'CONTACT', 'phone': '403 943 9917'}, {'name': 'Alexander J Clark, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': 'Foothills Medical Centre', 'geoPoint': {'lat': 51.05011, 'lon': -114.08529}}], 'centralContacts': [{'name': 'Alexander J Clark, MD, FRCPC', 'role': 'CONTACT', 'email': 'john.clark@albertahealthservices.ca', 'phone': '403 943 9917'}], 'overallOfficials': [{'name': 'Alexander J Clark, MD, FRCPC', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Calgary'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Calgary', 'class': 'OTHER'}, 'responsibleParty': {'oldNameTitle': 'Alexander J Clark MD FRCPC', 'oldOrganization': 'University of Calgary'}}}}
