Their diagnostic and prognostic performance will be checked against histological reading of the biopsies and evolution of the graft function over time.', 'detailedDescription': 'Background: In renal allograft recipients, 10-year graft survival has not much improved over the past decades. There is thus a need for robust, non-invasive methods to predict and diagnose acute and chronic graft lesions, to improve patient treatment, quality of life and long-term graft survival. Also, there is an unmet need for better understanding of the immune and non-immune mechanisms of interstitial fibrosis /tubular atrophy and graft loss. Several teams have searched for biomarkers of renal graft lesions, but there has been no cross-fecundation of the different "omics" approaches, nor any consolidation of the different clusters of biomarkers discovered using different technologies. An analysis of these different omics levels based on the principles of systems biology is therefore necessary to gain insight into the disease mechanisms and will help to develop predictors at the individual level. Purpose: The European project BIOMARGIN aims to discover, select and validate blood and/or urine biomarkers of renal allograft lesions in adult and paediatric kidney transplant recipients by integrating several omics approaches (mRNA, miRNA, peptides, proteins, lipids and metabolites) in blood, graft tissue and urine. The European cohort study BECS aims to evaluate the diagnostic and prognostic performance of the selected biomarkers over the first 3 and 5 years post-transplantation. Study design: This is a multicenter, international, ambispective, open and non-interventional cohort study, with collection of biological samples. Number of subjects: 450 adult and 50 paediatric renal transplant recipients. Outcomes: The primary endpoint is the graft outcome, assessed at three years as any lesion appeared on graft biopsies after patient enrolment, decline in graft function ≥ 30%, graft loss or patient death. Secondary endpoints include: histological findings in indication biopsies as well as in systematic biopsies (as per centre procedures) at 5 years; cumulated acute rejection episodes; 3-year and 5-year graft survival; and change of renal function assessed by the glomerular filtration rate (GFR) estimated using the MDRD formula. Statistical analysis: The sensitivity, specificity, positive and negative predictive values of the different biomarkers or sets of biomarkers will be evaluated for each of the primary and secondary endpoints. In order to compare the performance of the biomarkers with those of the other known risk factors for the deterioration of renal graft function, longitudinal statistical modelling will be used.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '1 Year', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'The eligible patients, 450 adults and 50 pediatrics, will be recruited among the whole list of patients followed for their kidney transplantation in the five investigating centres.', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria for paediatric patients :\n\n* Male or female\n* Age between 1 and 17 years inclusive\n* Recipient of a kidney allograft in the 24 months prior to enrolment, provided blood and urine samples had been collected between transplantation and enrolment in conditions compatible with those described in this protocol\n* Written informed consents of both parents or subject's legally authorized representative prior to any study procedure being performed\n* Assent form for the children more than 6 years old\n\nInclusion Criteria for adult patients:\n\n* Male or female\n* Age ≥18 years old (no upper age limit)\n* Recipient of a kidney allograft in the 24 months prior to enrolment, provided blood and urine samples had been collected between transplantation and enrolment in conditions compatible with those described in this protocol\n* Written informed consent prior to any study procedure being performed\n\nExclusion Criteria:\n\n* Patients unable to understand the information given by the investigator\n* Children less than one year old\n* Transplantation of any organ other than the kidney prior or concomitant to the kidney allograft\n* Patients returned to dialysis at the time of enrolment"}, 'identificationModule': {'nctId': 'NCT02832661', 'acronym': 'BECS', 'briefTitle': 'BIOMARGIN European, Ambispective Cohort of Adult and Paediatric Renal Transplant Patients', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Limoges'}, 'officialTitle': 'BIOMARGIN European, Ambispective Cohort of Adult and Paediatric Renal Transplant Patients for the Evaluation of the Diagnostic and Prognostic Performance of Biomarkers of Renal Graft Injuries', 'orgStudyIdInfo': {'id': 'I15038'}, 'secondaryIdInfos': [{'id': 'grant agreement no: 305499', 'type': 'OTHER_GRANT', 'domain': "European Community's Seventh Framework Programme (FP7)"}]}, 'contactsLocationsModule': {'locations': [{'city': 'Leuven', 'status': 'RECRUITING', 'country': 'Belgium', 'contacts': [{'name': 'Maarten NAESSENS', 'role': 'CONTACT'}], 'facility': 'University of Leuven - KU Leuven', 'geoPoint': {'lat': 50.87959, 'lon': 4.70093}}, {'zip': '87 042', 'city': 'Limoges', 'status': 'RECRUITING', 'country': 'France', 'contacts': [{'name': 'Pierre MARQUET, MD, PhD', 'role': 'CONTACT', 'email': 'pierre.marquet@unilim.fr', 'phone': '05 55 05 60 17'}], 'facility': 'University Hospital - INSERM', 'geoPoint': {'lat': 45.83362, 'lon': 1.24759}}, {'zip': '87042', 'city': 'Limoges', 'status': 'RECRUITING', 'country': 'France', 'contacts': [{'name': 'Marie ESSIG', 'role': 'CONTACT'}], 'facility': 'University Hospital - INSERM', 'geoPoint': {'lat': 45.83362, 'lon': 1.24759}}, {'city': 'Paris', 'status': 'RECRUITING', 'country': 'France', 'contacts': [{'name': 'Dany ANGLICHEAU', 'role': 'CONTACT'}], 'facility': 'Necker Children University Hospital', 'geoPoint': {'lat': 48.85341, 'lon': 2.3488}}, {'city': 'Toulouse', 'status': 'RECRUITING', 'country': 'France', 'contacts': [{'name': 'Stéphane DECRAMER', 'role': 'CONTACT'}], 'facility': 'Purpan Children University Hospital', 'geoPoint': {'lat': 43.60426, 'lon': 1.44367}}, {'city': 'Hanover', 'status': 'RECRUITING', 'country': 'Germany', 'contacts': [{'name': 'Wilfried GWINNER', 'role': 'CONTACT'}], 'facility': 'Medizinische Hochschule Hannover (MHH)', 'geoPoint': {'lat': 52.37052, 'lon': 9.73322}}], 'centralContacts': [{'name': 'Pierre MARQUET, MD, PhD', 'role': 'CONTACT', 'email': 'pierre.marquet@unilim.fr', 'phone': '+33 555 05 61 07'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital, Limoges', 'class': 'OTHER'}, 'collaborators': [{'name': 'Hannover Medical School', 'class': 'OTHER'}, {'name': 'KU Leuven', 'class': 'OTHER'}, {'name': 'Hôpital Necker-Enfants Malades', 'class': 'OTHER'}, {'name': 'Hospital Purpan', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
