The primary outcome measure will be the change in the coefficient of variation of continuous glucose readings, as assessed by CGM. Importantly, FLAT-SUGAR will plan, a priori, to assess glycemic variability using CGM. Secondary trial goals will be to explore potential between-group differences in complications that may result from glycemic variability, including hypoglycemia, systemic inflammation and oxidant stress, diabetic renal disease, weight gain and cardiac arrhythmias. If, as we expect, FLAT-SUGAR demonstrates that CGM provides objective verification of reduced glycemic variability in T2DM with the new GLP-1 agonist-based regimen, the main goal of the trial will be accomplished. If reduced variability is associated with lower risks of adverse events of inflammation, albuminuria progression, weight gain, hypoglycemia, and/or cardiac arrhythmia, a long term clinical comparative effectiveness trial powered to evaluate medical outcomes will be justified.
