Objective: We purpose to confirm the effect of teneligliptin (Tenelia), a selective dipeptidyl peptidase-4 (DPP-4) inhibitor, on glycemic control and non-glucose risk factors for macroangiopathy, including blood pressure, lipid metabolism, and body weight. Methods: In a prospective, multicenter, open-label, observational study, teneligliptin (20 mg/day) was administered to type 2 diabetic patients with poor glycemic control (HbA1c ≥ 6.5% to <10%) at our hospitals. The safety of teneligliptin and its impact on blood glucose, blood pressure, and the lipid profile were assessed after administration for 3 and 6 months. Results: One hundred and sixty-two patients were enrolled between February 2014 and August 2015. HbA1c was 7.6% at baseline and showed significant reduction to 7.1% after 3 months of treatment and to 6.9% after 6 months (both p < 0.01). Patients with poorly controlled hypertension (systolic blood pressure [SBP] ≥130 mmHg and/or diastolic blood pressure [DBP] ≥80 mmHg) at study initiation were extracted to investigate the effect of teneligliptin on blood pressure. SBP showed a significant decrease from 141.2 ± 9.8 mmHg at baseline to 131.1 ± 14.3 mmHg after 3 months and 133.9 ± 11.5 mmHg after 6 months (both p < 0.001). DBP also decreased significantly from 85.8 ± 5.7 mmHg at baseline to 78.4 ± 10.0 mmHg after 3 months and 79.7 ± 10.1 mmHg after 6 months (both p < 0.001). Adverse events were pruritus in four patients, and cerebral infarction was reported as a cerebrovascular event in one patient. Conclusions: Teneligliptin therapy was safe and improved glycemic control irrespective of baseline HbA1c. Blood pressure was also improved in patients with concomitant hypertension.
