Comprehensive efficacy of ipragliflozin on various conditioned type 2 diabetes compared with dipeptidyl peptidase-4 inhibitors and with both agents, based on a real-world multicenter trial

Abstract

Aims: The effects of ipragliflozin, the first sodium-glucose co-transporter 2 inhibitors (SGLT2i) launched in Japan in 2014, and with dipeptidyl peptidase-4 inhibitors (DPP-4i) on glycemic control and metabolic changes were investigated comprehensively on various conditioned type 2 diabetes (T2DM) by evaluating various clinical parameters in a real-world setting. Materials and methods: A total of 101 patients with T2DM aged 20–80 years with 7.0% ≤ HbA1c < 10.0% were followed in this 52-week, open-label, prospective, real-world, multicenter study. Results: HbA1c decreased significantly in all groups. In ipragliflozin using groups, body weight, waist circumference, blood pressure, HOMA-IR, AST, ALT, γ-GTP, uric acid and leptin levels decreased, in contrast, HDL-cholesterol, total ketone bodies, blood urea nitrogen, creatinine, RBC, hemoglobin and hematocrit levels increased, however, in DPP-4i sole group, no significant trends were observed in these parameters. Change in leptin positively correlated with insulin, while change in total ketone bodies inversely correlated with ALT in ipragliflozin using groups. Fasting active gastric inhibitory polypeptide levels decreased in ipragliflozin sole group. Glucagon showed no changes. No significant safety concerns were observed in this study. Conclusions: Ipragliflozin is useful and safe, showing some contrastive effects on several clinical parameters which are not shown with DPP-4i, resulting several clinical benefits. The co-administration of ipragliflozin and a DPP-4i has a better clinical outcome than either single-agent therapy.
