Heart and Kidney Ketones Metabolism

July 18, 2023 updated by: Université de Sherbrooke

Exogenous Ketone Salt on Heart and Kidney Ketone Metabolism Measured by Positron Emission Tomography

Participants will undergo 3 Positron Emission Tomography (PET) scans in 3 different conditions :

  1. Fasting without exogenous ketone salt
  2. Fasting with exogenous ketone salt supplement
  3. Post-Prandial with exogenous ketone salt supplement.

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

This study will help to quantify heart and kidney ketone uptake with or without an exogenous ketone salt with or without food intake in middle-aged adults. Participants will have 3 different PET scan to perform :

  1. Fasting without exogenous ketone salt
  2. Fasting with exogenous ketone salt supplement
  3. Post-Prandial with exogenous ketone salt supplement.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
No Intervention: Control
Fasting without exogenous ketone salt supplement
Experimental: Fasting with exogenous ketone salt supplement
Dietary supplement: Fasting with exogenous ketone salt supplement
Participants will have to take 2 doses of supplement, one 75 minutes before the scan and one 30 minutes before the scan.
Other Names:
  • Post-Prandial with exogenous ketone salt supplement
Experimental: Post-Prandial with exogenous ketone salt supplement
Dietary supplement: Post-Prandial with exogenous ketone salt supplement
Participants will have to take 2 doses of supplement, one 75 minutes before the scan and one 30 minutes before the scan and they will have a liquid meal 20 minutes before the scan.

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.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
