Study Details

Brief 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 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.

9\. Treatment with a glucagon-like peptide-1 receptor agonist or co-agonist in the last 3 months.

10\. Treatment with an SGLT2 inhibitor in the last 3 months. 11. Pregnancy or breast-feeding. Women of child-bearing potential will be required to have undergone surgical sterilization or to be using an intra-uterine device, hormonal contraceptive, or barrier methods of birth control.

12\. Cardiovascular disease such as myocardial infarction within six months prior to enrollment, presence of angina pectoris, significant arrhythmia, congestive heart failure (left ventricular hypertrophy acceptable), deep vein thrombosis, pulmonary embolism, -second- or third-degree heart block, mitral valve stenosis, aortic stenosis, or hypertrophic cardiomyopathy 13.

History of pancreatitis or pancreatic surgery 16. History or presence of immunological or hematological disorders 17. Clinically significant gastrointestinal impairment that could interfere with drug absorption 18. History of advanced liver disease with cirrhosis 19. Individuals with an eGFR<45 mL/min/1.73 m2, where eGFR is determined by the four-variable Modification of Diet in Renal Disease (MDRD) equation, where serum creatinine is expressed in mg/dL and age in years: eGFR (mL/min/1.73m2)=186 • Scr-1.154 • age-0.203 • (0.742 if female) 20. Treatment with chronic systemic glucocorticoid therapy (more than 7 consecutive days in 1 month) 21. Treatment with anticoagulants 22.

History of alcohol abuse (>14 per week for men and >7 per week for women) or illicit drug use 24. Treatment with any investigational drug in the one month preceding the study 25. Previous randomization in this trial 26. Mental conditions rendering a subject unable to understand the nature, scope and possible consequences of the study 27. Inability to comply with the protocol in the opinion of the principal investigator, e.g., uncooperative attitude, inability to return for follow-up visits, and unlikelihood of completing the study

Criteria Related to Known Adverse Effects of Drug:

28\. Uncircumcised men or men with history of balanitis 29. History of urinary incontinence 30. History of recurrent (>3) episodes of vulvovaginitis per year, or severe symptoms 31.

Interventions and Outcome Measures

Arms

active comparator: Empagliflozin Arm

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. To ensure blinding, empagliflozin will be over-encapsulated in identical gelatin capsules as placebo.

placebo comparator: Placebo Arm

Placebo consists of gelatin capsules.

Interventions

Empagliflozin 25 MG

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.

Placebo

Placebo consists of gelatin capsules.

Primary outcome measure

  • Adipose tissue macrophages [ Time Frame: 12 weeks ]
  • Flow mediated dilation [ Time Frame: 12 weeks ]
  • Monocyte chemoattractant protein-1 [ Time Frame: 12 weeks ]
