Primary Objective:

To evaluate the effects of rifampicin on the pharmacokinetics (PK) of sotagliflozin and its metabolite in healthy male and female subjects.

Secondary Objectives:

• To assess total 24-hour urinary glucose excretion (UGE) after a dose of sotagliflozin 400 mg, alone and with rifampicin, in healthy male and female subjects.
• To assess the safety and tolerability of single dose sotagliflozin with and without rifampicin in healthy male and female subjects.
