Metabolic Effects of Exogenous 3-hydroxybutyrate in Patients With Type 1 Diabetes and Healthy Controls

March 7, 2022 updated by: University of Aarhus

The main objective of this clinical trial is to study the metabolic effects of intravenous infusion of the ketone body, 3-hydroxybutyrate (3-OHB), in patients with type 1 diabetes and healthy control subjects. Moreover, the investigators plan to examine regulatory mechanisms of 3-OHB that may be related to diabetic ketoacidosis.

The hypotheses are:

  1. 3-OHB related inhibition of lipolysis is impaired in patients with type 1 diabetes.
  2. Intravenous infusion of 3-OHB affects signaling pathways involved in the metabolic regulation in patients with type 1 diabetes and healthy controls.
  3. 3-OHB infusion improves cardiac function in patients with type 1 diabetes and healthy controls.

The effects of 3-OHB will be investigated by isotopic tracers examinations, fat and muscle biopsies and blood samples. To evaluate effects on cardiac function echocardiography will be performed.

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.

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.

Ages Eligible for Study

18 years to 60 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Male

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.
Outcome Measure
Measure Description
Time Frame
Differences in lipolysis rate
Time Frame: After 3 hours of interventions
Measured as differences in palmitate flux
After 3 hours of interventions

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in protein metabolism
