Safety and effectiveness of tofogliflozin in elderly Japanese patients with type 2 diabetes mellitus: A subanalysis of a post-marketing study (J-STEP/EL Study).

ABSTRACT: AIMS/INTRODUCTION:This subanalysis aimed to assess the safety and effectiveness of tofogliflozin by using data from the Japanese Study of Tofogliflozin with Type 2 Diabetes Mellitus Patients in an Observational Study of the Elderly to categorize elderly Japanese patients with type 2 diabetes mellitus by the number of concomitant oral antidiabetic drugs (OADs) and insulin use at baseline. MATERIALS AND METHODS:Japanese Study of Tofogliflozin with Type 2 Diabetes Mellitus Patients in an Observational Study of the Elderly is a 1-year prospective, observational and multicenter post-marketing study that enrolled all patients with type 2 diabetes mellitus aged ?65 years who started tofogliflozin during the first 3 months after its launch in May 2014 in Japan. RESULTS:The safety and effectiveness analysis sets included 1,497 and 1,422 patients, respectively. Overall, 18.10 and 2.20% of the patients experienced adverse drug reactions (ADRs) and serious ADRs, respectively. ADRs of special interest in the total, 0 OAD, one OAD, two OADs, three or more OADs and insulin groups occurred in 12.22, 10.04, 12.35, 13.32, 11.27 and 14.91% of patients, respectively. Volume depletion-related events were the most frequently observed ADRs of special interest. Hypoglycemia occurred in 1.07% of patients. Overall, glycated hemoglobin and bodyweight were significantly decreased, but the estimated glomerular filtration rate was not significantly changed. CONCLUSIONS:Our finding suggests that tofogliflozin could be safely and effectively used in elderly Japanese patients with type 2 diabetes mellitus, irrespective of the number of OADs and the use of insulin.
