A Pharmacodynamics, Pharmacokinetics, and Safety Study of Hydrochlorothiazide and Canagliflozin in Healthy Volunteers

An Open-Label, Two-Period, Fixed-Sequence Study to Explore the Effects of Multiple Doses of Hydrochlorothiazide on the Pharmacodynamics, Pharmacokinetics, and Safety of Multiple Doses of Canagliflozin in Healthy Subjects

The purpose of the study is to evaluate the effects of multiple doses of hydrochlorothiazide and canagliflozin on the concentrations of each drug in the blood and the concentration of glucose in the blood and urine in healthy adult volunteers.

This is a single-center, open-label study with 2 study periods where volunteers and study staff will know the names and doses of assigned study treatments. All volunteers will receive the same treatment. Canagliflozin (a sodium-glucose cotransporter 2-inhibitor) is currently under development to lower blood sugar levels in patients with Type 2 diabetes mellitus (T2DM), and hydrochlorothiazide (HCTZ) is a drug indicated for the treatment of patients with mild to moderate hypertension. During Period 1, volunteers will take canagliflozin 300 mg once daily for 7 days (Days 1 to 7) and during Period 2, volunteers will take HCTZ 25 mg once daily for 28 days (Days 1 to 28), and then starting on Day 29, will take canagliflozin 300 mg once daily and HCTZ 25 mg once daily for 7 days (Days 29 to 35). Period 1 and Period 2 will be separated by a minimum of 14 days.
