Effect of Food Order on Postprandial Glucose Excursions in Pre-Diabetes

May 14, 2018 updated by: Weill Medical College of Cornell University
The natural history of type 2 diabetes commonly follows a pattern of postprandial dysregulation followed by fasting hyperglycemia leading to overt type 2 diabetes. Approximately 38% of the US adult population is estimated to have pre-diabetes. In a previous study of 16 overweight/obese patients with metformin treated type 2 diabetes, using a typical Western meal, investigators demonstrated that a food order in which protein and vegetables are consumed first, before carbohydrate, results in significant lowering of incremental glucose peaks compared to the reverse order. In the present study, investigators seek to expand on the previous findings to gain further insight into the impact of food order in individuals with pre-diabetes, using a meal with different macronutrient composition, in the setting of three meal patterns. The study is designed to be a simple, practical intervention that may have very significant clinical implications for prevention of diabetes in a large population at increased metabolic risk.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
