About this study
Diabetic nephropathy (kidney problems caused by diabetes) is a devastating chronic vascular complication of diabetes. New treatments are urgently needed for preventing or slowing down the progression of diabetic kidney disease. Samples of serum/plasma/urine will be obtained from patients with diabetes and different degree of renal impairment.
In this project cells in culture will be treated with plasma or serum or urine; cells extracts or supernatant will be studied to screen for modulation (activation/inhibition) of different cellular pathways using gene array, metabolomic and/or proteomic. Once some cellular pathways have been identified specific analysis will be conducted on the biological material collected to confirm specific "cell signatures" that could represent potential target for treatment.
Read the detailed description
The aim of the study is to investigate novel putative mechanisms involved in the pathophysiology of kidney disease in diabetic patients.
The investigators will make use of plasma, serum or urine obtained from patients with diabetes.
Cells in culture will be treated with plasma or serum or urine; cells extracts or supernatant will be studied to screen for modulation (activation/inhibition) of different cellular pathways using gene array, metabolomic and/or proteomic. Once some cellular pathways have been identified specific analysis will be conducted on the biological material collected to confirm specific "cell signatures" that could represent potential target for treatment.
The investigators will recruit patients with both type 1 and type 2 diabetes attending our outpatient diabetes clinic at Guys' and St Thomas Hospital. The participant will be informed of the aim of the research and if agreeable in donating blood and urine sample; participants will be asked to sign a written informed consent explaining in simple word the aim of the research, the involvement they should have (blood sample and urine sample collection), the minimal risk to which they will be exposed (venopuncture).
The study will involve one or more blood collections from the arm, for up to 30 mls (6 tea spoons) per year (up to 10 yeas duration), to be collected on up to 2 occasions/ year (minimum time between two collections: 4 weeks), with up to 15ml (3 tea spoon) of blood maximum volume taken per occasion. Urine samples (any amount) might also be collected at any time. Blood and urine collections will take approximately 15 minutes.
This research is low risk. Samples will be stored within the Unit of Metabolic Medicine (Dr Gnudi), King's College London, United Kingdom, and its potential future use will be within the remit of the advancement of science and for the benefit of public domain within academic and/or commercial organisations (e.g. pharmaceutical industry) worldwide.
Any information collected from participants during the course of the research will be kept strictly confidential. Any information leaving the hospital will have the name and address of patient removed so that it can not be recognised by third parties.
The results obtained from this research will likely to be published in a medical journal. The investigators will provide copy of any published results to anybody that may request for it. Participants will not be identified in any report/publication.

Questions about this trial
What is this clinical trial studying?
An observational study of Diabetes Complications, run by Guy's and St Thomas' NHS Foundation Trust at 1 site in United Kingdom.
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 1 inclusion and 1 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: withdrawn, as of the sponsor's last update on 15 Feb 2019. 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 United Kingdom. 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 was withdrawn before enrolling participants, so there are no results.
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?
Cellular phenotype (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 15 Feb 2019.
