About this study
Official title: Costituzione Della Biobanca Del Microbiota Intestinale e Salivare Umano: Dalla Disbiosi Alla Simbiosi
This is a prospective, clinical, multicentre study aimed to collect biological samples and study microbiota from subjects with morbid obesity, metabolically healthy obesity and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological)
The study will allow to:
- Provide biological samples (faeces, saliva, blood, urine) from healthy volunteers and patients to the first Italian microbiota biobank;
- Study microorganisms using different in vitro and in vivo techniques;
- Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.
Read the detailed description
The primary aim of this multicentric study is to populate the first national microbioma biobank with biological samples (fecal, salivary, urinary and blood samples) subjects suffering from selected disease (morbid obesity, metabolically healthy obesity), and healthy volunteers.
The secondary aim is the characterization of microorganisms of the biobank and study of the microbiota-pathology relationship using meta-omics, in vitro and in vivo approaches.
The study plans to enrol 60 subjects at Policlinico of Bari, according to the inclusion/exclusion criteria. The study participation is voluntary, and the subjects have the right to withdraw from the study at any time and for any reason.
During the study, 3 visits are planned:
- Visit 0 (V0), including description of the objectives and procedures study, signature written informed consent, inclusion/exclusion criteria evaluation, medical examination (blood pressure measurement, abdominal and thoracic physical examination), body composition through bioimpedance analysis and metabolic, cardiovascular and respiratory variables; OGTT 75gr for blood glucose and insulin at times 0, 30, 60, 90 and 120', and a nocturnal oximetry and subsequently, if necessary, overnight polysomnography for the diagnosis of obstructive sleep, filling in of the anamnestic questionnaire, delivery of the coproculture kit, delivery of kits for the collection of fecal, salivary and urinary material to be reported at Visit 1 and delivery of a 3-day food diary, to be completed autonomously in the days preceding the Visit 1.
- Visit 1 (V1) - at least 4 days after V0, including delivery of the of the collected biological material (feces, saliva, urine), and of a 3-day food diary, filling in of the new signs and symptoms anamnestic questionnaire and blood sampling by medical staff.
- Telephone evaluation: administration of a "Food Frequency Questionnaire" to assess the subjects' alimentary habits.
Standard Operative Procedures (SOP) for samples storing, transport and processing will be adopted to ensure samples stability and grant results validity and quality.
Following collections, samples will be processed in different aliquots that will be used for:
- routine screening;
- storage in the first Italian human microbiote biobank (I.R.C.C.S. - Istituto Tumori "Giovanni Paolo II", Bari);
- evaluation of the proteomic, metascriptomic, metabolomic, metagenomic, and metagenetic profile;
- Evaluation of the transcriptomic profile of PBMCs of healthy subjects and subjects affected by selected pathologies and evaluation of the serum proteomic profile Furthermore, molecular characterization of pathogenic microorganisms and pathogenic biotypes (pathovars) of commensal species of subjects with selected pathologies will be conducted.
Part of the biological material will be used for animal studies on the physiopathological role of the human intestinal microbiota transplanted into mouse models of pathology and Germ-free mouse models (specific animal study protocol developed).
Also, in vitro studies on mucosal models to evaluate the interaction between the microbiota and the intestinal mucosa will be conducted.
The study foresees no more than minimal risk associated with blood sampling procedures. All the necessary measures to avoid any risks / inconveniences resulting from participation of the subject under study will be taken.
The study is compliant with Good Clinical Practice. Study protocol and all related documents have been approved by approved by the Independent Ethics Committees (IEC) of the involved clinical sites.
To ensure the protection and confidentiality of the participants' data, all study activities will be carried out in accordance with the European General Data Protection Regulation, Regulation (EU) 2016/679, which repeals Directive 95/46/EC.

Questions about this trial
What is this clinical trial studying?
An observational study of Morbid Obesity and Metabolically Healthy Obesity, run by Azienda Ospedaliero-Universitaria Consorziale Policlinico di Bari at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Biological samples collection for establishment of the first National Microbiome Biobank (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04698135, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2023.
