January 24, 2020 updated by: King's College London

The INTER-CARDIO Study: The Impact of Commonly Consumed Fat on Cardiovascular

The purpose of this study is to investigate whether there are differences in postprandial cardiometabolic metabolic indices following interesterified fats used commercially versus application appropriate non- interesterifed alternative fat.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Aim: The current study aims to investigate the acute effects of commercially available interesterified fat versus versus application appropriate non- interesterifed alternative fat on 8 h postprandial cardiometabolic outcomes.

Hypothesis: Interesterified fat will induce a different cardiomtabolic response compared to a non interesterifed, application appropriate fat.

Subjects: Participants will include 40 healthy male and female volunteers aged between the ages of 35 and 75 years (since during this age metabolic changes start to take place).

Power calculation: Based on previous studies carried out by our group at King's College London, a sample size of 20 participants (males and females separately) will allow a 2.16% (percentage unit) difference in FMD to be detected (90% power, 0.05 alpha, SD 2.9. 50 participants will be recruited allowing for a 20% dropout rate.

Expected value:The study will provide novel information on the acute effects of commercially relevant processed fats on postprandial lipaemia.

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.
