QTc prolongation Safety and Effectiveness of Teneligliptin in Indian patients with type 2 Diabetes Mellitus: A real world study (QSET 2)

Abstract Aims To evaluate the safety with respect to QTc prolongation and effectiveness of Teneligliptin in Indian Type 2 Diabetes Mellitus (T2DM) patients. Methods Retrospective data of T2DM patients on teneligliptin 20 mg or 40 mg once daily as a monotherapy or add-on therapy and having ECG records (before and after teneligliptin initiation) was collected. Safety was evaluated by change in QTc interval and effectiveness was evaluated by changes in fasting plasma glucose (FPG), postprandial plasma glucose (PPG), and haemoglobin A1C (HbA1c) from baseline to 12-weeks. Results There was no significant change in mean QTc interval from baseline [418.68 milli seconds (ms) to 419 ms; mean change +0.33 ms; P = 0.1023] to follow up visit (mean duration 91 days). There was a significant reduction from baseline to 12 weeks in FPG [173.1 mg/dl (9.61 mmol/L) to 128.4 mg/dl (7.12 mmol/L), mean change - 44.64 mg/dl (2.47 mmol/L), P ≤ 0.001], PPG [242.5 mg/dl (13.46 mmol/L) to 176.5 mg/dl (9.79 mmol/L), mean change - 65.93 mg/dl (3.66 mmol/L), P ≤ 0.001], and HbA1c [8.2% (66 mmol/mol) to 7.2% (55 mmol/mol), mean change - 1.00% (10.9 mmol/mol), P ≤ 0.001]. Conclusion Teneligliptin did not cause QTc interval prolongation and was significantly effective in improving glycemic control.
