About this study

Official title: The Effect of Ingestion of Foods on the Plasma Glucose and Insulin Response in Subjects With Type 2 Diabetes: Protein, Amino Acids & Insulin & Glucagon Secretion in Humans

The purpose of this study is to determine the effect of various foods and/or food substances such as fats or proteins on the blood glucose and insulin concentrations in people with and without type 2 diabetes.

Read the detailed description

Various foods or food substances are given as a test meal. The metabolic response is determined at various times after the administration of the meal (e.g. blood glucose, and other hormones and metabolites).

Being tested
water, glucose with or without amino acid
Keywords
Glycemic Index, LoBAG Diet, Insulin, Glucagon
Medical subject headings
Diabetes Mellitus, Type 2, Metabolic Syndrome, Insulin Resistance

What participants receive

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in blood glucose concentration

    Test substances will be given at 0800 hr and blood drawn at several time points up to 5 hours after the meal.

    Measured: several time points after ingestion of test substance

Secondary outcomes (1)
  1. Change in serum insulin concentration

    Test substances will be given at 0800 hr and blood drawn at several time points up to 5 hours after the meal.

    Measured: Several time points after ingestion of test substance

Questions about this trial

What is this clinical trial studying?

A study testing water, glucose with or without amino acid in people with Type 2 Diabetes and Metabolic Syndrome, run by Minneapolis Veterans Affairs Medical Center at 1 site 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 3 inclusion and 6 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: paused, as of the sponsor's last update on 8 Nov 2017. 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 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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?

Change in blood glucose concentration (time frame: several time points after ingestion of test substance). 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 NCT01471509, which also lists 43 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 8 Nov 2017.
