Objective. Canagliflozin is a sodium glucose co-transporter 2 inhibitor approved for
treating patients with type 2 diabetes. This study evaluated renal and non-renal effects of
canagliflozin on postprandial plasma glucose (PG) excursion in patients with type 2 diabetes
inadequately controlled with metformin.
Materials/Methods. Patients (N = 37) were randomized to a four-period crossover study
with 3-day inpatient stays in each period and 2-week wash-outs between periods.
Patients received Treatments (A) placebo/placebo, (B) canagliflozin 300 mg/placebo,
(C) canagliflozin 300 mg/canagliflozin 300 mg, or (D) canagliflozin 300 mg/canagliflozin
150 mg on Day 2/Day 3 in one of four treatment sequences (similar urinary glucose
excretion [UGE] expected for Treatments B–D). A mixed-meal tolerance test (MMTT) was
given 20 minutes post-dose on Day 3 of each period.
Results. A single dose of canagliflozin 300 mg reduced both fasting and postprandial PG
compared with placebo, with generally similar effects on fasting PG and UGE observed for
Treatments B–D. An additional dose of canagliflozin 300 mg (Treatment C), but not 150 mg
