Inhibitors of the sodium-glucose co-transporter (SGLT2) are FDA-approved for the treatment of type 2 diabetes (T2DM). Their mechanism of action involves lowering of blood glucose concentration secondary to increased glucose excretion of glucose by the kidney. These drugs also improve body weight, blood pressure, and cardiac function. Based on these pleiotropic effects, including its calorie restriction-mimetic properties, the study team hypothesize that SGLT2 drugs will impact several basic aging-related processes, including reductions in oxidative damage to DNA and proteins, advanced glycation end products (AGE) and receptor for AGE (RAGE), cellular senescence, and mitochondrial function.


Investigations into the aging process have identified major cellular dysfunctions that contribute to aging, including but not limited to increased burden of damaged DNA and protein, reduction in mitochondrial respiration, and the development of pro-inflammatory senescent cells. Developing and testing interventions that interact with multiple points of this spectrum may delay the aging process. Based on prior investigations, the study team believe the SGLT2 inhibitor class of drugs may target these basic mechanisms involved in the aging process and propose testing in a high-risk human population to evaluate their effectiveness in ameliorating aging-associated dysfunctions. Specifically, the investigators hypothesize that SGLT2i drugs will lead to reductions in oxidative damage to DNA and proteins, AGE-RAGE, and cellular senescence, which will be accompanied by improvements in mitochondrial function. If the hypothesis is correct, these findings could lead to the development of new approaches to increase both health-span and lifespan.

This is a single center, open-label, randomized controlled trial. The target enrollment for this pilot study is 20 completed subjects, split evenly between experimental and control groups. Each subject will be randomized to either the experimental group of dapagliflozin 10mg daily for 12 weeks or the control group of nutritional counseling for weight loss. Health-span and clinical evaluations will be taken at baseline and at weeks 10-12 of the study.
