Clinical 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 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.

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. Presence of implanted cardiac defibrillator or pacemaker

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. Any underlying or acute disease requiring regular medication which could possibly pose a threat to the subject or make implementation of the protocol or interpretation of the study results difficult

23. 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:
