Clinical Trial Summary

There is a growing understanding of the functioning and interconnectedness of microbiomes in the food system which offers great potential for enabling the development of new solutions contributing to achieving important food and nutrition goals including those requested by FOOD 2030. Of relevance in this regard is the provision of sustainable and healthy protein sources. Because of the obvious environmental and climate concerns associated with the production of animal-derived protein, a transition is needed to healthier and more environment-friendly diets, including a moderate-level consumption of red and processed meat and greater emphasis on plant-based foods. As well as impact of meat production on the climate, it is well established that eating a diet rich in red meat promotes the growth of gut microbiome members that drive or exacerbate inflammation. Plant protein does not have these associations, and in fact it is often accompanied by fibre ingestion, which favours growth of health-promoting gut microbes. Replacing meat with plant protein offers the prospect of improving consumer health by improving the gut microbiome. The EU funded project MICROBIOMES4SOY will assess the effect of replacing animal protein with soya-derived protein on the human gut microbiome and whether this replacement can reduce the risk of inflammation-related diseases by gut microbiome modulation. This knowledge will provide a baseline for establishing new dietary pathways making use of soya protein and support dietary transition for EU citizens.

Participants will return to the study site for Visit 6 (Follow-up Visit) at day 70, having completed the follow-up phase of the study. The following procedures will be carried out: - Participant's continued consent to study procedures will be confirmed. - Concomitant medication/supplements will be recorded. - Adverse events will be recorded. - Participants will return the collected stool sample and will be stored for further analysis. Data processing & Management Data required for the analysis will be acquired and transferred electronically to a central database by means of an Electronic Data Capture system (the "EDC-tool"). The EDC-tool will comprise an eCRF, designed specifically for the present study. High security standards for the transfer and storage of study data are guaranteed using technologies such as encrypted data transfer, firewalls, and periodic backup to protect centrally stored data. The eCRF is based on the electronic data capture system developed by Clindox, which is fully compliant with and a Gold Member of the Clinical Data Interchange Standards Consortium. The eCRF will be hosted on a dedicated validated stand-alone server placed in a double locked server room. According to the standards of the data protection law, all data obtained in the course of the study will be treated with discretion in order to guarantee the rights of the Participant's privacy. Monitoring The responsible monitor will contact and visit the clinical site regularly and will be allowed, on request, to review the various records of the study (CRFs/eCRFs and other pertinent data) provided that Participant confidentiality is maintained in accordance with local requirements and as specified in the contract. The monitor will review the study documents (e.g., CRFs) at regular intervals throughout the study, to verify the adherence to the protocol and the legibility, completeness, consistency, and accuracy of the data being entered on them. The monitor will have access to laboratory test reports and other Participant records needed to verify the entries on the CRF/eCRF. This source data verification may be carried out remotely. Quality assurance and quality control All Study Product used will be subjected to quality control. Quality assurance audits will be performed by the Sponsor (or any health authority) during the course of the clinical study or after its completion. Adverse Events (AE): For purposes of this study all AEs reported will be unexpected. The causality assessment of an AE to the investigational and/or study procedure(s) product will be rated as Unrelated, Unlikely, Possible, Probable or Definite using accepted criteria for clinical trials. The severity of AEs will be recorded, including the start and stop dates for each change in severity, and graded on a five-point-scale in accordance with the Common Terminology Criteria for Adverse Events. The outcome of AEs will be followed up and recorded. All Adverse Events (AEs) occurring during clinical studies will be recorded in the eCRF. During the study, complete reports of all AEs will be entered in the Participants site source documents, and if applicable, on the appropriate study case report forms (CRFs). A licensed clinician will be responsible for: identifying and evaluating the severity (mild, moderate, or severe) and clinical importance of the AE, taking appropriate medical action(s), and for notifying the Sponsor immediately of an SAE as specified in the protocol and for notifying the Science Department for reporting to the IRB/IEC. For any laboratory abnormality, the PI or Sub-Investigator will make a judgement as to its clinical significance. The PI or Sub-Investigator will comply with applicable regulatory requirement(s) related to the reporting of SAEs to the IRB/IEC. The Monitor(s) will review completed CRF data and will compare CRF entries with information recorded in the source documents. Any discrepancies or omissions in either data source will be discussed with the site personnel who should make the appropriate corrections to the documents. ;
