Tofogliflozin (USAN, codenamed CSG452) is an experimental drug for the treatment of diabetes mellitus and is being developed by Chugai Pharma in collaboration with Kowa and Sanofi.^[1] It is an inhibitor of subtype 2 sodium-glucose transport protein (SGLT2), which is responsible for at least 90% of the glucose reabsorption in the kidney. As of September 2012, the drug is in Phase III clinical trials.^[2][3]
