Abstract

Background: Sotagliflozin (LX4211) is a dual inhibitor of sodium-glucose cotransporter (SGLT)1 and SGLT2 being investigated to improve glycemic control in adults with diabetes. This study was firstly conducted to assess the pharmacokinetic (PK), pharmacodynamic (PD) profiles, safety and tolerability in Chinese healthy subjects after administration of sotagliflozin.

Methods: This was a Phase I, randomized, double-blind, placebo-controlled, ascending multiple-dose study. Healthy subjects received 200mg or 400mg of sotagliflozin or placebo once daily for 8 days, respectively. PK parameters of sotagliflozin and LX4211-GLU (main metabolite), as measured by blood samples collected pre/postdose on Day 1/predose on Day 2-Day 8/postdose on Day 8, and PD parameters of absolute urinary glucose excretion (UGE) were determined. Treatment-emergent adverse events (TEAEs) were evaluated.

Results: Overall, 24 subjects were enrolled and randomized to sotagliflozin 200 mg (N = 9), sotagliflozin 400 mg (N = 9), or placebo (N = 6) group, and all subjects completed the study. Sotagliflozin was rapidly absorbed with dose-proportional systemic exposure and a moderate degree (less than 2-fold) of accumulation. Sotagliflozin plasma concentrations peaked at 1.0 h post dose. On Day 8, the estimated increases for Cmax and AUCtau were 1.89-fold and 1.70-fold. The pooled accumulation ratio of sotagliflozin was 1.57 for Cmax and 1.84 for AUCtau. LX4211-GLU had similar PK features. UGE was significantly elevated in both sotagliflozin groups relative to the placebo group. All TEAEs were mild and resolved without sequelae. There were no serious AEs or other significant TEAEs.

Conclusion: Sotagliflozin was rapidly absorbed with dose-proportional systemic exposure and a moderate degree of accumulation. Both 200 mg and 400 mg sotagliflozin per day were well tolerated in Chinese healthy subjects.
