About this trial
This study is a randomized, double-blind, placebo-controlled trial specifically designed to evaluate the preliminary feasibility, initial efficacy and safety of SGLT2 inhibitors for treating NAFLD in adolescents with obesity.

Trial outcomes
Primary outcomes
Efficacy as Measured by Change in Hepatic Fat Fraction (HFF)
HFF is measured by MRI via 1H- magnetic resonance spectroscopy (MRS). HFF will be measured with single-voxel 1H-MRS on a 3.0 T Trio whole body MRI scanner, using the software package provided by the vendor. The MR elastography measurement will consist of a phase-contrast 2D GRE scan (TR/TE = 50/25 ms, matrix 256 x 90, GRAPPA R=3, slice thickness 7mm) with motion encoding in the z-direction, and acoustic excitation at 60 Hz. Four axial slices will be acquired, each with a single breath-hold. Manual ROIs covering the liver will be drawn on the stiffness maps (in kPa units) generated by the system software. Fibrosis staging will be determined following previously published guidelines.
Secondary outcomes
Change in Body Measurements: Body mass index (BMI)
Height and weight will be measured using a calibrated, wall-mounted stadiometer and an electronic scale, respectively. Three consecutive height and weight measurements will be obtained and averaged. BMI will be calculated as the weight in kilograms divided by the height in meters, squared.
Change in Body Measurements: Body Fat %
Total percent body fat mass and lean muscle mass will be determined by dual energy x-ray absorptiometry (iDXA, GE Healthcare). Body fat percentage is calculated by body fat mass divided by the sum of fat and lean masses.
Change in Body Measurements: Visceral Fat %
Total body fat mass and visceral fat mass will be determined by dual energy x-ray absorptiometry (iDXA, GE Healthcare). Visceral fat percentage of total body mass is calculated by visceral fat mass divided by the sum of total fat and lean masses. Visceral fat percentage of total fat mass is calculated by visceral fat mass divided by total fat mass.
Change in Biomarkers of NAFLD: Alanine transaminase (ALT)
Fasting (≥12 hours) blood will be collected for the measurement of ALT at Fairview Diagnostics Laboratories, Fairview-University Medical Center, Minneapolis, MN - a Center for Disease Control and Prevention certified laboratory.
