Detailed Description
In this study, a total of 48 healthy subjects were enrolled and assigned to one of three groups of 16 subjects. Each group participated in an open-label, non-randomized, fixed-sequence studies to assess potential interaction of bexagliflozin tablets, 20 mg with probenecid, rifampin or verapamil.
Sequence 1: Bexagliflozin/probenecid Sixteen healthy subjects were dosed with bexagliflozin, qd and/or probenecid tablets, 500 mg, bid, in sequential order as follows: on Day 1 subjects took bexagliflozin; on Days 3 and 4 subjects took probenecid, bid; on Day 5 subjects took one bexagliflozin, and probenecid, bid; and on Day 6 subjects took probenecid tablets, 500 mg, bid.
Sequence 2: Bexagliflozin/rifampin Sixteen healthy subjects were dosed with bexagliflozin, qd and/or 600 mg of rifampin daily in sequential order as follows: on Day 1 subjects took one bexagliflozin tablet; on Days 3 to 5, subjects took rifampin once daily; on Day 6 subjects took one bexagliflozin tablet and rifampin; and on Day 7 subjects took rifampin.
Sequence 3: Bexagliflozin/verapamil Sixteen healthy subjects were dosed with bexagliflozin, and/or verapamil tablets, 120 mg in sequential order as follows: on Day 1 subjects took one bexagliflozin tablet, on Day 4 subjects took one verapamil tablet, 1 hour before taking a bexagliflozin tablet.
