Improved glycemic control with teneligliptin in patients with type 2 diabetes mellitus on hemodialysis: Evaluation by continuous glucose monitoring

Aims Recent reports suggest that appropriate glycemic control without hypoglycemia could decrease mortality in patients with diabetes mellitus (DM) and end-stage renal disease (ESRD). However, an indication of oral anti-diabetic drugs is limited in this population. The aim of this study was to evaluate efficacy of teneligliptin, a novel DPP-4 inhibitor, by continuous glucose monitoring (CGM) in patients with type 2 DM (T2DM) on hemodialysis (HD). Methods This 4-week, open label, single arm, intervention trial included 10 diabetic patients undergoing HD and with glycated albumin (GA) level of ≥18.3%. Teneligliptin treatment was administered on days with HD sessions (HD day) and on days without HD sessions (NHD day); blood glucose values were measured by CGM. The primary endpoint was improvement of glycemic control evaluated by area under the curve (AUC). As secondary endpoints, changes in GA, HbA1c and fasting plasma glucose (FPG) were evaluated. Results Teneligliptin improved blood glucose AUC on both HD days (p=0.004), and NHD days (p=0.004). This was accompanied by a significant reduction in GA, HbA1c, and FPG, without severe hypoglycemia. Conclusions Teneligliptin is one of the useful options for glycemic control in T2DM patients undergoing HD.
