Trial summary
The purpose of this study is to evaluate the effectiveness of nutritional supplements in increasing the amount of omega-3 fatty acids (and arginine) in the red blood cell membranes and plasma of kidney transplant patients, and, secondarily, to compare patient compliance. Read more about this study

About this study
Official title: A Randomized Trial of Immunomodulating Diets With Arginine and Omega-3 Fatty Acids in Renal Transplant Recipients
The purpose of this study is to evaluate the effectiveness of nutritional supplements in increasing the amount of omega-3 fatty acids (and arginine) in the red blood cell membranes and plasma of kidney transplant patients, and, secondarily, to compare patient compliance. The long-term goal of this study is to develop low risk therapies that will allow improved and lasting survival of donor tissue with minimal suppression of the immune system.
Read the detailed description
Short-term survival rates of donor tissue after kidney transplantation have improved significantly in recent years because of improved immunosuppression. Rates of long-term tissue loss have changed less because of a high incidence of chronic rejection, infectious complications, and cardiovascular disease. Data suggest that both early and late complications might be reduced in transplant recipients by dietary intervention to raise levels of omega-3 fatty acids and arginine.
Prior to transplantation, participants are randomized to one of three groups. Group 1 participants serve as controls and receive no dietary supplements. Participants in Group 2 receive daily nutritional supplements of arginine and canola oil according to body weight. Group 3 participants receive daily nutritional supplements of arginine and a fish oil emulsion according to body weight. All participants receive a standard, low-fat dietary consultation. The status of participants is evaluated peri-transplant and at 1, 3, 6, and 9 months.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Canola oil, Arginine and Fish oil emulsion in people with Kidney Diseases, run by National Institute of Allergy and Infectious Diseases (NIAID) at 4 sites in United States.
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 5 inclusion and 11 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 11 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in United States. 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.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Increases in omega-3 fatty acid levels in plasma and red blood cell membranes observed in each of the three omega-3 supplements used in this study. 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 NCT00047983, 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 11 Jan 2017.
