About this study
Patients undergoing renal transplantation at London Health Sciences Centre, University Hospital and who are participating in the study "A Comparison of Effects of Standard Dose vs Low Dose Advagraf with IL-2 Receptor Antibody Induction, MMF and Steroids, With or Without ACEi/ARB-based Antihypertensive Therapy on Renal Allograft Histology, Function, and Immune Response" will be evaluated with the ImmuKnow Assay to assess the ability of this assay to predict underimmunosuppression (rejection) or overimmunosuppression determined by this test and to determine retrospectively whether decision making utilizing this novel assay would have improved outcomes over standard techniques.
This study is designed to evaluate an in vitro assay (Cylex®ImmuKnow Assay) for the measurement of cell-mediated immune response in renal transplant patients receiving immunosuppressive therapy. This assay measures ATP as an activation response of CD4+ cells to stimulation with phytohemagglutinin (PHA) in whole blood samples as a reflection of the immune system of the patient at any point in therapy. The natural history of the immune status of the renal transplant recipient as reflected by the ImmuKnow assay will be determined at specific time points of interest including: pre and post transplant, as an adjunct to therapeutic drug monitoring, and pre and post infectious or rejection episode. Analysis of the results of the assay at these time points will allow us to retrospectively study the effects of routine immunosuppressive agent modulation on immune function, and its subsequent effects in times of renal allograft insult.

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 2 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: finished, as of the sponsor's last update on 2 Sep 2015. 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 Canada. 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?
Immune status (time frame: A sample will be collected pre-transplant as well as for an expected average of 6 months post-transplant.). 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 2 Sep 2015.
