Trial summary

Obesity is associated with increased cardiometabolic disease risk due, in part, to heightened chronic inflammation arising from adipose tissue. There are no current targeted therapies to prevent or reverse the chronic inflammation of obesity, and a better understanding of these inflammatory pathways in humans is key… Read more about this study

About this study

Obesity is associated with increased cardiometabolic disease risk due, in part, to heightened chronic inflammation arising from adipose tissue. There are no current targeted therapies to prevent or reverse the chronic inflammation of obesity, and a better understanding of these inflammatory pathways in humans is key to future therapeutic interventions. This trial will determine both the anti-inflammatory potential of the SGLT2 inhibitor empagliflozin, and the contribution of adipose inflammation to surrogate measures of cardiovascular disease in a randomized controlled trial of obese patients.

What participants receive

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

  • Empagliflozin 25 MGDrug

    Also called Jardiance

    Empagliflozin is an FDA-approved SGLT2 inhibitor used for the treatment of type 2 diabetes, with off-label use for diabetic kidney disease and for heart failure with reduced ejection fraction even in those without diabetes.

  • PlaceboDrug

    Placebo consists of gelatin capsules.

Empagliflozin ArmActive comparatorEmpagliflozin is an FDA-approved SGLT2 inhibitor used for the treatment of type 2 diabetes, with off-label use for diabetic kidney disease and for heart failure with reduced ejection fraction even in those without diabetes. To ensure blinding, empagliflozin will be over-encapsulated in identical gelatin capsules as placebo.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Empagliflozin 25 MG in people with Obesity and Metabolic Syndrome, run by Vanderbilt University Medical Center 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 6 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: 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Mona Mashayekhi, MD, PhD (615-208-5037, mona.mashayekhi@vumc.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adipose tissue macrophages (time frame: 12 weeks). The study lists 3 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 5 Nov 2026; AzTrials last refreshed its copy on 8 Nov 2026.
