Effect of Monosodium L-Glutamate (MSG) and Nucleic Acid (IMP) on Satiety and Food Intake

February 7, 2013 updated by: Ajinomoto Co., Inc.

A Randomized, Double-Blind, Placebo-Controlled, Crossover Clinical Study of Monosodium L-Glutamate (MSG) and Nucleic Acid (IMP) to Evaluate the Effects on Satiety and Food Intakes at the Next Meal in Healthy Adults

The objective of this study is to confirm that Monosodium L-Glutamate (MSG) supplementation, both alone or in combination with Nucleic Acid (IMP), enhances satiety and decreases food intakes at the next meal in healthy female adults.

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.

Detailed Description

The study is a randomized, double-blind, placebo-controlled, cross-over clinical trial. A total of 80 women aged 30 to 45 y will be randomized to a sequence of test product administration.

Subjects will be required to meet several inclusion and exclusion criteria, which will be assessed at the screening visit, including a general screening questionnaire, medical/medication history, eating disorder questionnaire, eating inventory questionnaire, dietary inventory questionnaire, and anthropometric and vital sign measurements. At the screening visit, a urine sample will be collected for drug and alcohol screening, cotinine level, and pregnancy. Alcohol breath test will be performed as well.

After assessment of the eligibility criteria, qualified subjects will be invited to participate in the study. This study will take approximately 3 weeks to complete.

Subjects will return to the study site within 28 days after the screening visit for testing period 1, followed by 2 additional visits (testing period 2 and 3).

Subjects will consume 1 of 3 treatments, based on randomization sequence at each test period visit: Consommé soup with Monosodium L-Glutamate (MSG), Consommé soup with MSG and Nucleic Acid (IMP), and Placebo soup with no MSG or IMP.

When subjects arrive at the research center at approximately 11:30am, admission procedures will be conducted: an alcohol breath test, food and activity diary review, and vital signs and weight will be measured. If vital sign measurements are elevated, subjects will be rescheduled within 2-3 days. Right before serving the standard lunch meal, subjects will be asked to complete a satiety motivational questionnaire. Subjects will consume the entire standard lunch meal and water within 30 min. Immediately after eating the standard lunch meal, subjects will complete the satiety motivational questionnaire.

Two hours after the standard lunch meal, subjects will be given one of the test soups (based on their randomization) to consume in its entirety, followed by completion of the satiety motivational questionnaire and the soup rating questionnaire. Fifteen minutes from test soup administration, snacks and water (ad lib) will be provided and subjects will be instructed to eat as much as or as little as they desire, followed by completing the satiety motivational questionnaire. At 3 h 15 min and at 4 h, subjects will complete the satiety motivational questionnaire.

Test periods 2 and 3 will be scheduled between 3-14 days after completing test period visit 1: all procedures are identical on each test period visit with the exception of the test treatment soup consumed by subjects.

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.

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.
