effect of rifampicin on the pharmacokinetics and pharmacodynamics of sotagliflozin

Conditions: Diabetes Mellitus

Summary: 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.

the expected duration of the study is approximately 53 days total, including 2-28 days of screening, treatment periods of 6 days and 11 days, 1 day of end of study visit, and at least 7 days of follow-up visit.
