Among patients with chronic pain about one third suffer from comorbid PTSD, which further complicates their already challenging pharmacological regimens. Low dose ketamine infusion has shown promise in PTSD, and in treatment of chronic pain, however they have not been studied in comorbid population and under rigorous control conditions. The investigators compared the effects of a single dose of either ketamine (0.5 mg/kg) or ketorolac (15 mg) over a 40-minute of IV infusion in chronic pain patients with and without PTSD, in double blind, randomized study. Measures were collected before, during, 1 day and 7 days after the infusion.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\nVeterans with chronic pain as defined by having any chronic pain beyond 6 months in duration with and without PTSD diagnoses (participants must meet DSM-V criteria for current post-traumatic stress disorder (PTSD) and have received a diagnosis of PTSD greater than or equal to 3 months prior to assessment); they also will be either free of concomitant use of psychotropic and/or pain medications for at least 6 weeks or on stable doses of those medications within the last 6 weeks prior to randomization and for the duration of the study; if applicable, current frequency and duration of psychotherapy sessions must remain stable for at least 6 weeks prior to beginning of the study.\n\nExclusion Criteria:\n\nInability to speak English, inability or unwillingness to provide written informed consent; moderate-to-severe cognitive impairment (Mini-Mental State Examination scores\\<20 administered by a trained clinician); current or lifetime history of psychotic or bipolar disorder; current bulimia or anorexia nervosa, alcohol abuse or dependence in the previous 3 months; serious unstable medical illness or sleep apnea; HTN, prolonged QT interval, peptic ulcer disease or recent history of GI-bleed, renal insufficiency, active substance use disorder, active suicidal or homicidal ideation on presentation; pregnancy (confirmed by baseline lab test), the initiation of female hormonal treatments within 3 months of screening, or inability or unwillingness to use a medically accepted contraceptive method for the duration of the study.'}, 'identificationModule': {'nctId': 'NCT04322968', 'briefTitle': 'Ketamine Infusion for Comorbid PTSD and Chronic Pain', 'organization': {'class': 'FED', 'fullName': 'VA Ann Arbor Healthcare System'}, 'officialTitle': 'Low Dose Ketamine Infusion for Comorbid Posttraumatic Stress Disorder and Chronic Pain Patients', 'orgStudyIdInfo': {'id': 'IRB-2017-1015'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Chronic pain with PTSD+IV ketamine infusion', 'interventionNames': ['Drug: A single low dose ketamine infusion as compared to the IV infusion of active placebo - ketorolac on chronic pain and PTSD symptoms.']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Chronic pain with PTSD+IV ketorolac infusion', 'interventionNames': ['Drug: A single low dose ketamine infusion as compared to the IV infusion of active placebo - ketorolac on chronic pain and PTSD symptoms.']}, {'type': 'EXPERIMENTAL', 'label': 'Chronic pain without PTSD+IV ketamine infusion', 'interventionNames': ['Drug: A single low dose ketamine infusion as compared to the IV infusion of active placebo - ketorolac on chronic pain and PTSD symptoms.']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Chronic pain without PTSD+IV ketorolac infusion', 'interventionNames': ['Drug: A single low dose ketamine infusion as compared to the IV infusion of active placebo - ketorolac on chronic pain and PTSD symptoms.']}], 'interventions': [{'name': 'A single low dose ketamine infusion as compared to the IV infusion of active placebo - ketorolac on chronic pain and PTSD symptoms.', 'type': 'DRUG', 'description': 'Subjects were randomized into 4 treatment groups: chronic pain subjects treated with ketorolac, chronic pain subjects treated with ketamine, chronic pain+PTSD subjects treated with ketorolac, and chronic pain+PTSD subjects treated with ketamine.', 'armGroupLabels': ['Chronic pain with PTSD+IV ketamine infusion', 'Chronic pain with PTSD+IV ketorolac infusion', 'Chronic pain without PTSD+IV ketamine infusion', 'Chronic pain without PTSD+IV ketorolac infusion']}]}, 'contactsLocationsModule': {'locations': [{'zip': '48105', 'city': 'Ann Arbor', 'state': 'Michigan', 'country': 'United States', 'facility': 'Ann Arbor VA Medical Center', 'geoPoint': {'lat': 42.27756, 'lon': -83.74088}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO', 'description': 'Local IRB has conducted informed consent audit for the study and the investigators have been compliant with it.'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'VA Ann Arbor Healthcare System', 'class': 'FED'}, 'collaborators': [{'name': 'University of Michigan', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
