Supplemental Hydrogen Plus PQQ for Mitochondrial Biomarkers and Brain Function in Elderly With Mild Cognitive Impairment (CALERIE)

December 3, 2024 updated by: Sergej Ostojic, University of Novi Sad, Faculty of Sport and Physical Education

The Effects of Six-week Hydrogen Plus Pyrroloquinoline Quinone (PQQ) Intake on Mitochondrial Biomarkers, Brain Metabolism and Cognition in the Elderly With Mild Cognitive Impairment

The goal of this randomized controlled double-blind parallel-group interventional trial is to evaluate the effects of dietary supplementation with molecular hydrogen and pyrroloquinoline quinone in elderly. The main questions it aims to answer are: (1) whether the supplementation affects biomarkers of mitochondrial function in serum, and (2) whether the supplementation affects cognition and brain metabolism. The participants will be subjected to take the dietary supplement during 6 weeks.

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

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

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
Fibroblast growth factor 21
Time Frame: Change from baseline serum fibroblast growth factor 21 at 6 weeks

Change from baseline serum fibroblast growth factor 21 at 6 weeks

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
Peroxisome proliferator-activated receptor gamma coactivator 1-alpha
Time Frame: Change from baseline serum peroxisome proliferator-activated receptor gamma coactivator 1-alpha at 6 weeks

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.
