the number of calories fed to mice prevent EAE and are also associated with less severe disease in mice who do develop the disease. Currently, whether these results translate favorably in humans is unknown. This is a pilot trial of testing two caloric restriction (CR) diets versus a control diet in multiple sclerosis (MS) patients: one continuous caloric restriction (CR) diet where a small number of calories will be restricted every day or another intermittent CR diet where a caloric intake will be restricted more severely 2 days per week. Participants are randomized to one of the diets, and for the first 8 weeks, will receive standardized, prepared meals tailored to the specific diet. At the conclusion of the controlled feeding study, all participants will transition to an unblinded phase for an additional 40 weeks where they are provided with instructions to follow an intermittent CR diet.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '50 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Aged 18-50\n* Capable of storing food safely, willing to follow diet/eat provided food, and able to receive shipments at home or work\n* Meets 2010 criteria for McDonald MS;\n* Relapse or new lesion in previous 2 years\n* Expanded disability status score (EDSS) \\< 6\n* Disease duration ≤15 years\n* Untreated or on stable on first-line MS therapy \\[injectable\\] for at least 6 months, with no anticipated changes in the next 10 weeks\n* Unchanged vitamin D dose or thyroid replacement dose (for those on it) with no anticipated changes or in supplement use for the next 10 weeks.\n* Non-regular smoker (average no more than 1 cigarette/day) for at least 2 months\n* Stable weight, by self report, for past 3 months (± 8 lbs)\n* Body mass index (BMI) \\> 23 kg/m2\n\nExclusion Criteria:\n\n* Pregnant or nursing, or unwilling to prevent pregnancy (if of childbearing to potential)\n\n * History of gastrointestinal disease causing malabsorption\n * History of diabetes requiring medication\n * History of stage IV/V chronic kidney disease or vascular disease\n * History of major surgery in past 3 months\n * Current use of warfarin\n * History of eating disorder\n * Currently on a special diet for MS/other diet (provided diet will be pork free)\n * Chemotherapy within the past year'}, 'identificationModule': {'nctId': 'NCT02647502', 'briefTitle': 'A Pilot Study of Intermittent Calorie Restriction in Multiple Sclerosis', 'organization': {'class': 'OTHER', 'fullName': 'Johns Hopkins University'}, 'officialTitle': 'A Pilot Study of Intermittent Calorie Restriction in Multiple Sclerosis', 'orgStudyIdInfo': {'id': 'IRB00065806'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Continuous calorie restriction', 'description': 'Participants will be provided with a diet that includes approximately 78% of calories each day that would be needed to maintain current BMI.', 'interventionNames': ['Other: Diet']}, {'type': 'EXPERIMENTAL', 'label': 'Intermittent calorie restriction', 'description': 'Participants will be provided a diet that with a daily calorie intake required to maintain current BMI, except only 25% of this calorie intake will be provided for 2 days a week.', 'interventionNames': ['Other: Diet']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Control calorie intake', 'description': 'Participants will be assigned to consume enough calories each day required to maintain current BMI', 'interventionNames': ['Other: Diet']}], 'interventions': [{'name': 'Diet', 'type': 'OTHER', 'description': 'Diet, standardized to the 50th percentile for macronutrients, will be provided at varied calorie levels as described.', 'armGroupLabels': ['Continuous calorie restriction', 'Control calorie intake', 'Intermittent calorie restriction']}]}, 'contactsLocationsModule': {'locations': [{'zip': '21287', 'city': 'Baltimore', 'state': 'Maryland', 'country': 'United States', 'facility': 'Johns Hopkins University', 'geoPoint': {'lat': 39.29038, 'lon': -76.61219}}], 'overallOfficials': [{'name': 'Ellen Mowry, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Johns Hopkins University'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Johns Hopkins University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Associate Professor of Neurology and Epidemiology', 'investigatorFullName': 'Ellen M.
