About this study

Official title: Neurophysiological Effects of Whole Coffee Cherry Extract in Older Adults: An fMRI Investigation

This study was designed to characterize the changes in the brain and body associated with whole coffee cherry extract (WCCE). WCCE is a patented extract of whole coffee fruit (coffee berries) from coffea arabica. Whole coffee cherries are a source of naturally occurring nutrients. There are no known side effects or allergens associated with WCCE other than that which would be associated with a consuming typical cup of coffee.

Previous studies suggest that increases in serum concentrations of both serum total and exosomal brain-derived neurotrophic factors (BDNF) may represent one of the mechanisms responsible for improved cognitive function after acute WCCE administration. Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and the more serious decline of dementia. It can involve problems with memory, language, thinking and judgment that are greater than normal age-related changes. Furthermore, MCI is associated with reduced circulating BDNF. Due to earlier studies reporting the ability of WCCE to stimulate increases in circulating and exosomal BDNF, it has been postulated that WCCE may also acutely improve cognitive function (as measured using behavioral tasks and fMRI). The purpose of this study is to extend and elucidate the findings of previous investigations by examining the acute neurophysiological effects of WCCE using blood-oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy (MRS) employing a double-blind, randomized crossover design to investigate the acute effects of a single dose of WCCE or placebo (silica oxide) on neuronal activity in older participants.

What is being measured

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

  1. Behavioral Measures - Change in Go/No-Go Reaction Time

    Response/reaction time for each stimuli will be recorded in ms using E-Prime. Reaction times will be calculated for correct and incorrect trials separately.

    Measured: Collected pre-drug, post-drug, pre-placebo, and post-placebo; through study completion (4 time points over a 72 hour period)

  2. Behavioral Measures - Change in N-back Reaction Time

    Response/reaction time for each stimuli will be recorded in ms using E-Prime. Reaction times will be calculated for correct and incorrect trials separately.

    Measured: Collected pre-drug, post-drug, pre-placebo, and post-placebo; through study completion (4 time points over a 72 hour period)

  3. Behavioral Measures - Change in Go/No-Go Accuracy

    Accuracy will be determined as the number of trials correct, and errors will be classified as errors of omission or commission.

    Measured: Collected pre-drug, post-drug, pre-placebo, and post-placebo; through study completion (4 time points over a 72 hour period)

  4. Behavioral Measures - Change in N-back Accuracy

    Accuracy will be determined as the number of trials correct.

    Measured: Collected pre-drug, post-drug, pre-placebo, and post-placebo; through study completion (4 time points over a 72 hour period)

  5. Change in Concentration of Neurometabolites

    Magnetic resonance spectroscopy (MRS) measurements pre/post ingestion. The following are measured: glutamate, glutamine, gamma-aminobutyric acid, N-acetylaspartate, choline, creatine, glutathione, myo-inositol, aspartate, taurine, and lactate. LCModel software performed automatic quantification of in vivo proton MR spectra by analyzing spectra as a linear combination of model spectra from sequence-specific simulations. Water-suppressed spectra were eddy current corrected and quantified using the unsuppressed water signal. Cramer-Rao lower bounds were used as a measure of fit with CRLB > 50% rejected from further analysis. Metabolite concentrations were CSF-corrected, and quantified (in ppm).

    Measured: Collected pre-drug, post-drug, pre-placebo, and post-placebo; through study completion (4 time points over a 72 hour period)

  6. Change in Blood Levels of Brain Derived Neurotrophic Factor (BDNF)

    Serum and exosomal BDNF concentrations

    Measured: Collected pre-drug, post-drug, pre-placebo, and post-placebo; through study completion (4 time points over a 72 hour period)

  7. Blood Oxygen Level Dependent (BOLD) Changes

    Functional magnetic resonance imaging blood-oxygen-level-dependent signal changes across tasks, and during resting state

    Measured: Collected pre-drug, post-drug, pre-placebo, and post-placebo; through study completion (4 time points over a 72 hour period)

Questions about this trial

What is this clinical trial studying?

A study testing Whole coffee cherry extract (WCCE) in people with Memory Deficits, run by Auburn University.

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 2 inclusion and 5 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 23 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Behavioral Measures - Change in Go/No-Go Reaction Time (time frame: Collected pre-drug, post-drug, pre-placebo, and post-placebo; through study completion (4 time points over a 72 hour period)). The study lists 7 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 23 Jan 2019.
