A study testing Oral glucose tolerance test and Oral lipid tolerance test in people with Healthy Subjects, run by University College Dublin at 2 sites in Ireland.
Trial summary
The purpose of this study is to investigate the biological response to a metabolic stress, given in the form of a high carbohydrate or fat meal in normal weight, overweight and obese individuals and to further explore these responses using novel metabolomic, proteomic, transcriptomic and genotyping techniques.

About this study
Official title: A Nutrigenomics Study of Post-prandial Metabolic Responses in Individuals of Varying Body Weight: An Assessment of the Body's Response to Meals Containing Different Levels of Fat and Carbohydrate
The purpose of this study is to investigate the biological response to a metabolic stress, given in the form of a high carbohydrate or fat meal in normal weight, overweight and obese individuals and to further explore these responses using novel metabolomic, proteomic, transcriptomic and genotyping techniques.
Read the detailed description
The most recent statistics from the Department of Health in Ireland (2005) indicate that the leading causes of death are those in which nutrition can play a key preventative role. The proposed study will provide information on the metabolic stress from varying body weight overlaid by the additional metabolic stress of a test-meal challenge, in this case being delivered in the form of an oral glucose tolerance test (OGTT) and oral lipid tolerance test (OLTT), standard metabolic challenges in post-prandial research. Previous studies assessing metabolic risk factors associated with a disease have typically focused on information collected from individuals in a fasting state only. However, it is equally important to assess how the body responds when stressed. Employing an acute high fat or carbohydrate intake is sufficient to induce a mild stress in which time an individual's unique post-prandial response can be monitored. This study will combine traditional markers (dietary, anthropometric, lifestyle, clinical and physical activity) with nutrigenomics, a tool that attempts to describe the genome-wide influences of nutrition by examining the impact of diet on genes (genomics), mRNA (transcriptomics), proteins (proteomics) and metabolites (metabolomics).

Questions about this trial
What is this clinical trial studying?
A study testing Oral glucose tolerance test and Oral lipid tolerance test in people with Healthy Subjects, run by University College Dublin at 2 sites in Ireland.
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 3 inclusion and 4 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 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Ireland. 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?
Comprehensive analysis of the metabolic response to the acute ingestion of fat and glucose loads (time frame: 2-5 hours post test meal ingestion). 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 NCT01172951, which also lists 8 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 2011.
