Sotagliflozin Decreases Postprandial Glucose and Insulin Concentrations by Delaying Intestinal Glucose Absorption

CONTEXT: The effect of sotagliflozin (a dual sodium–glucose cotransporter [SGLT] 2 and SGLT1 inhibitor) on intestinal glucose absorption has not been investigated in humans. OBJECTIVE: To measure rate of appearance of oral glucose (R(a)O) using a dual glucose tracer method following standardized mix...

Sumario:CONTEXT: The effect of sotagliflozin (a dual sodium–glucose cotransporter [SGLT] 2 and SGLT1 inhibitor) on intestinal glucose absorption has not been investigated in humans. OBJECTIVE: To measure rate of appearance of oral glucose (R(a)O) using a dual glucose tracer method following standardized mixed meals taken after single sotagliflozin or canagliflozin doses. SETTING: Clinical research organization DESIGN AND PARTICIPANTS: In a double-blind, 3-period crossover study (NCT01916863), 24 healthy participants were randomized to 2 cohorts of 12 participants. Within each cohort, participants were randomly assigned single oral doses of either sotagliflozin 400 mg, canagliflozin 300 mg, or placebo on each of test days 1, 8, and 15. On test days, Cohort 1 had breakfast containing [6,6-(2)H(2)] glucose 0.25 hours postdose and lunch containing [1-(2)H(1)] glucose 5.25 hours postdose; Cohort 2 had breakfast containing no labeled glucose 0.25 hours postdose and lunch containing [6,6-(2)H(2)] glucose 4.25 hours postdose. All participants received a 10- to 15-hour continuous [U-(13)C(6)] glucose infusion starting 5 hours before their first [6,6-(2)H(2)] glucose-containing meal. MAIN OUTCOME: R(a)O, postprandial glucose (PPG), and postprandial insulin. RESULTS: Sotagliflozin and canagliflozin decreased area under the curve (AUC)(0–1 hour) and/or AUC(0–2 hours) for R(a)O, PPG, and insulin after breakfast and/or the 4.25-hour postdose lunch (P < .05 versus placebo). After the 5.25-hour postdose lunch, sotagliflozin lowered R(a)O AUC(0–1 hour) and PPG AUC(0–5 hours) versus both placebo and canagliflozin (P < .05). CONCLUSIONS: Sotagliflozin delayed and blunted intestinal glucose absorption after meals, resulting in lower PPG and insulin levels, likely due to prolonged local inhibition of intestinal SGLT1 that persisted for ≥5 hours after dosing.
