To unravel whether providing personalized fibre mixtures, selected based on the individuals' initial microbiota and capacity for SCFA production is crucial to successfully improve host insulin sensitivity and metabolic health"}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '30 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\nOverweight/obese insulin resistant/prediabetic participants (age 30-70 y, BMI ≥ 28 kg/m2 \\< 40 kg/m2)\n\nExclusion Criteria:\n\n* Type 2 diabetes mellitus (defined as fasting plasma glucose ≥ 7.0 mmol/L and 2h glucose ≥ 11.1 mmol/L)\n* Gastroenterological diseases or abdominal surgery;\n* Cardiovascular diseases, cancer, liver or kidney malfunction, disease with a life expectancy shorter than 5 years;\n* Abuse of products; alcohol and drugs, excessive nicotine use defined as \\>20 cigarettes per day;\n* Plans to lose weight or following of a hypocaloric diet;\n* Regular supplementation of pre- or probiotic products, use of pre- or probiotics 3 months prior to the start of the study;\n* Intensive exercise training more than three hours a week;\n* Use of any medication that influences glucose or fat metabolism and inflammation (i.e. NSAIDs);\n* Regular use of laxation products;\n* Use of antibiotics in the last three months (antibiotics use can alter substantially the gut microbiota composition).\n* Follow a vegetarian diet.'}, 'identificationModule': {'nctId': 'NCT05378295', 'briefTitle': 'Personalized Fiber and Insulin Sensitivity', 'organization': {'class': 'OTHER', 'fullName': 'Maastricht University Medical Center'}, 'officialTitle': 'Personalized Microbial Substrates to Prevent Type 2 Diabetes', 'orgStudyIdInfo': {'id': 'NL76905.068.21'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'isocaloric fermentable oligosaccaride', 'description': 'isocaloric fermentable oligosaccaride', 'interventionNames': ['Dietary Supplement: Fermentable oligosaccharide']}, {'type': 'EXPERIMENTAL', 'label': 'Personalized fiber mixture', 'description': '12 g for 2 weeks, followed by 24 g for 10 weeks', 'interventionNames': ['Dietary Supplement: Personalized fiber mixture']}], 'interventions': [{'name': 'Fermentable oligosaccharide', 'type': 'DIETARY_SUPPLEMENT', 'description': 'Supplementation period 12 weeks', 'armGroupLabels': ['isocaloric fermentable oligosaccaride']}, {'name': 'Personalized fiber mixture', 'type': 'DIETARY_SUPPLEMENT', 'description': 'Supplementation period 12 weeks', 'armGroupLabels': ['Personalized fiber mixture']}]}, 'contactsLocationsModule': {'locations': [{'zip': '5229ER', 'city': 'Maastricht', 'state': 'Limburg', 'country': 'Netherlands', 'facility': 'Maastricht University', 'geoPoint': {'lat': 50.84833, 'lon': 5.68889}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Maastricht University Medical Center', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
