About this study

The purpose of this study is to examine if glucocorticoids will change neural activation in regions of the corticolimbic-striatal system that regulate feeding.

Read the detailed description

The primary hypothesis tested in this study will be to determine if that in response to food cues, glucocorticoids will change neural activation in regions of the corticolimbic-striatal system that regulate feeding. It is anticipate that these changes will correlate with hunger ratings and food intake. Further, this research will also examine if glucocorticoids will increase the basal metabolic rate and alter multiple systemic appetite-regulating hormones compared to saline. It is expected that these changes will correlate positively with hunger ratings and food intake as well.

What participants receive

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

  • hydrocortisoneDrug

    Hydrocortisone will be used as the steroid of choice because it is bio-identical to cortisol and is subject to the same metabolism as cortisol.

  • salineOther

    Saline will be used as the placebo comparator. It will be administered in the same manner as the active drug.

What is being measured

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

  1. Change in Brain Response to Food Imagery

    Brain response to images of food either during hydrocortisone infusion or saline infusion will be measured through fMRI. Brain response is operationally defined as the change in functional MRI-measured blood oxygen levels in specific regions of the brain between the resting state and intervention state. The fMRI sequences last anywhere from 1-5 min. Total scan time will be approximately 90 minutes. The slices taken with each sequences equal 25-75.

    The outcome is a comparison between the resting oxygen levels and oxygen levels during the interventions. BioImage Suite software is used to categorize if there is a significance between the two levels at a p < 0.05.

    Measured: 90 minutes

  2. Average Hunger Rating

    Average hunger rating will be captured using the Visual Food Cue Task. This standardized method presents a series of images consisting of high calorie food, low calorie food, and non-food pictures presented randomly across four runs during the fMRI session. Each picture will be presented only once in a randomized order for each participant.

    Participants will be instructed to rate their "hunger", "liking" and "wanting" of the item on a 9-point Likert scale utilizing a 4-key button box. The hunger, wanting, and liking scales are all rated on a scale of 1-9, 1 being the least and 9 being the most. These scores are presented as an average across measurement points during the fMRI. Every time a food image is shown, the rater provides a rating of hunger, wanting and liking of it- people will be shown approximately 40-60 photos.

    Measured: 90 minutes

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing hydrocortisone and saline in people with Obesity, run by Yale University at 1 site in United States.

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 22 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 25 May 2022. 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 United States. 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. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Change in Brain Response to Food Imagery (time frame: 90 minutes). 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 25 May 2022.
