Primary Objective:

To assess the effects of multiple-dose hydrochlorothiazide (HCTZ) on the steady-state pharmacokinetics (PK) of sotagliflozin.

Secondary Objectives:

• To assess the safety and tolerability of multiple-dose sotagliflozin with and without co-administration of multiple-dose HCTZ
• To assess the effects of multiple-dose sotagliflozin on the steady-state PK of HCTZ
• To assess the effects of multiple-dose HCTZ on the steady-state PK of sotagliflozin-3-O-glucuronide

Duration of the study for each subject will be between 33 to 77 days, including screening up to 28 days, 5 days of treatment Period 1, washout period of 7-21 days, 9 days of treatment Period 2, and follow-up period of 10-14 days after last dose of the Investigational Medicinal Product (IMP) in Period 2.
