About this study

The purpose of this study is to map the neural and molecular mechanisms underlying psychological stress-induced changes in inflammation which could reveal new targets for intervention to reduce the risk of cardiovascular disease.

Read the detailed description

The proposed work will conduct a mechanistic clinical trial utilizing the non-selective beta-adrenergic receptor blocker propranolol to examine the role of beta-adrenergic signaling in shaping neural and inflammatory responses to stress. The investigators will focus on beta-adrenergic signaling given seminal pre-clinical work showing that this molecular pathway is an important driver of stress-related increases in inflammation, and initial human neuroimaging work showing that beta-blockade leads to changes in neural responses to negative stimuli. Here, the investigators will bring these two previously disparate lines of work together to determine how experimentally blocking one critical stress-signaling pathway shapes neural activity and inflammatory responses to stress. In doing so, the investigators will be advancing knowledge by mapping mechanisms (i.e., beta-adrenergic signaling), offering methodological improvements (i.e., moving beyond correlation to using pharmacological manipulations to provide causal evidence), and identifying intervention targets (i.e., the neurocognitive systems that shift activity/connectivity in response to beta-blockade). In sum, the work proposed herein is significant because it will address the mechanisms by which one critical risk factor, psychological stress, may ultimately lead to cardiovascular disease via inflammation. The proposed study also offers significant methodological improvements over past work by using neuroimaging to identify neurocognitive pathways, and pharmacology to provide causal experimental evidence to move us beyond correlation. Finally, this project is significant because it could provide insight into novel targets for future interventions.

What is being measured

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

  1. Change in levels of pro-inflammatory cytokine interleukin-6 in response to social stress

    Blood plasma will be analyzed for levels of pro-inflammatory cytokine interleukin-6 (IL-6), from baseline, a baseline after drug administration, a sample 90-minutes after the stress task (T-90) measured in pg/mL. The timeline was determined on meta-analytic work showing changes in the inflammatory cytokine IL-6 are largest at 90 minutes post-stress.

    Measured: Post-drug baseline to 90-minutes post-stress task (T-90)

  2. Change in levels of inflammatory gene expression in response to social stress

    Whole blood samples will be collected in PaxGene tubes and analyzed for changes in inflammatory gene expression from baseline, a baseline after drug administration, and 30-minutes after the stress task (T-30), measured in gene transcript counts per million. The timeline is based on the Principal Investigator's work showing that changes in pro-inflammatory gene expression are observed 30-minutes post-stress.

    Measured: Post-drug baseline to 30-minutes post-stress task (T-30)

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 4 inclusion and 21 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: looking for participants now, as of the sponsor's last update on 5 Nov 2026. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Jonathan Bunting, BS (9164957661, jonb@unc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in levels of pro-inflammatory cytokine interleukin-6 in response to social stress (time frame: Post-drug baseline to 90-minutes post-stress task (T-90)). 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?

On the ClinicalTrials.gov record for NCT06263452, which also lists 58 linked publications.

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.
