Brief Summary:
The purpose of this study is to examine the drug-drug interaction in your body when given the study drug, bexagliflozin, with three commonly prescribed medications, probenecid, verapamil or rifampin. The study will also evaluate how safe the study drug is and how well the study drug is tolerated when taken with probenecid, verapamil or rifampin.
