Does Dapagliflozin Provide Additional Health Benefits To Dietary Counseling For Weight Loss?

• Status: Completed
• Trial end date: 2018-12-21
• Target enrollment: 0
• Participant gender: All

Summary

Dapagliflozin is a medicine to treat diabetes. Its mechanism of action is via sodium-glucose co-transporter 2 (SGLT2) inhibition. In adults with diabetes, use of sodium-glucose co-transporter 2 inhibitors is associated with moderate weight (fat) loss, in addition to other health benefits, including decreased blood pressure, decreased inflammation, and decreased oxidative stress. It is unclear as to whether these health benefits are due to SGLT2 inhibition per se, or as a secondary effect of weight loss. We wish to compare the health benefits of dietary counseling for weight loss with and without concomitant use of an SGLT2 inhibitor.
