Trial summary

This is a randomized, placebo-controlled, double-blinded crossover design. Fifteen healthy subjects will be randomized to receive either ketone bodies (KE4) or placebo delivered by KetoneAid.

About this study

This is a randomized, placebo-controlled, double-blinded crossover design. Fifteen healthy subjects will be randomized to receive either ketone bodies (KE4) or placebo delivered by KetoneAid. After a period of 5-days treatment, effect variables will be measured (experiment day 1). After a washout period of 14 days, the subjects are crossed over to a similar treatment period with the other treatment. The study is terminated by measuring effect variables after the second treatment period (experiment day 2).

Read the detailed description

Background: Renewed interest in ketone bodies has emerged, partly driven by the recent success of selective sodium glucose co transporter 2 (SGLT-2) inhibition in preventing cardiovascular deaths in patients with diabetes mellitus (DM) and chronic kidney disease (CKD). Effects of ketosis are of importance in order to understand the beneficial effects of SGLT-2 inhibitors and to account for the full therapeutic potential of this treatment.

Hypothesis: Ketosis increases renal blood flow and glomerular filtration rate (GFR).

Methods: It is a randomized, placebo-controlled double-blinded cross over study. Fifteen healthy subjects will be randomized to receive either ketone bodies (KE4) or for 5 days. After a wash out period of at least 14 days, the subjects are crossed over to receive the other treatment. After each treatment period effect variables will be measured including Technetium(Tc)99m - Diethylenetriamine pentaacetate (DTPA) clearance and water based positron emission tomography computed tomography (PET/CT)

Perspectives: The study has the potential to provide information regarding the therapeutic potential of treatment with ketone bodies and understanding of conditions characterized by ketosis, such as SGLT2-inhibitor treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Beta-hydroxybutyrateDietary supplement

    Each subject receive Beta-hydroxybutyrate 300mg/kg x 3 for five days. After the treatment period effect variables will be examined.

  • PlaceboOther

    Each subject receive a placebo drink 3 x day for five days. After the treatment period effect variables will be examined.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. GFR

    Change in GFR measured by Tc99m-DTPA clearance

    Measured: Measured after each treatment period (day 6 and approximately day 26)

  2. Renal Blood Flow (RBF)

    Change in RBF determined by water based PET/CT scans

    Measured: Subjects are scanned after each treatment period (day 6 and approximately day 26)

Secondary outcomes (4)
  1. 24-hour blood pressure

    Change in systolic 24-hour blood pressure

    Measured: Measured after each treatment period (day 6 and approximately day 26)

  2. Vasoactive hormones

    Change in plasma levels of angiotensin II, aldosterone, renin, brain natriuretic peptide (BNP), atrial natriuretic peptide (ANP), copeptin

    Measured: Measured after each treatment period (day 6 and approximately day 26)

  3. Beta-hydroxybutyrate

    Change ind p-beta-hydroxybutyrate

    Measured: Measured after each treatment period (day 6 and approximately day 26)

  4. Renal tubular transport proteins

    Urine excretions of aquaporin 2 (AQP2), thiazide-sensitive sodium-chloride cotransporter (NCC) and distal epithelial sodium channel (ENaC)

    Measured: Measured after each treatment period (day 6 and approximately day 26)

Questions about this trial

What is this clinical trial studying?

A study testing Beta-hydroxybutyrate in people with Ketosis and Ketonemia, run by Gødstrup Hospital at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

GFR (time frame: Measured after each treatment period (day 6 and approximately day 26)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Nov 2024.
