Effects of 1-year Treatment with Canagliflozin on Body Compo
Long-term changes in body composition associated with SGLT2 inhibitors have not been characterized.

In this multicenter, single-arm, open-label study, 107 subjects with type 2 diabetes were treated, as add-on therapy, with canagliflozin at 100 mg for 12 months. Body composition was measured with a body composition analyzer (T-SCAN PLUS) via the impedance method to prospectively analyze changes in body components, including percentage of body fat, body fat mass, total body water, muscle mass, and mineral mass. Estimated plasma volume (ePV) was calculated using the Kaplan formula.

Results:
-- Body weight showed a significant decrease from 1 month to 12 months of treatment with canagliflozin, with a higher rate of decrease in body fat in body composition.

-- A significant decrease in mineral mass was also observed, but its rate was low.

-- Following treatment with canagliflozin, changes in total body water did not affect intracellular water, and a significant decrease in extracellular water, including plasma components, was observed early and sustained up to 12?months.

-- Protein mass, a component of muscle mass, was not affected, with only a slight decrease in water volume observed.

Conclusively, Canagliflozin decreased extracellular fluid and plasma volume in addition to decreasing fat in the body due to calorie loss through urinary glucose excretion. This study suggested that SGLT2 inhibitors might reduce body weight by regulating fat mass or water distribution in the body and have cardiac and renal protective effects by resetting the homeostasis of fluid balance.
