エヴォグリプチンの2型糖尿病患者に対する有効性と安全性：多施設共同前向き観察研究

Evogliptin, a dipeptidyl peptidase-4 inhibitor with a glucose-dependent mechanism of action, is widely used as a monotherapy or in combination with other agents. However, observational studies in routine clinical settings remain limited. This study aimed to evaluate the effectiveness and safety of evogliptin in combination with other antidiabetic agents frequently used in clinical practice.

This study was conducted in 51 hospitals in South Korea. We evaluated evogliptin in three groups: the evogliptin add-on, evogliptin-switching, and initial combination groups. The primary endpoint was the change in haemoglobin A1c (HbA1c) levels (%) from baseline to 12 weeks. The change in HbA1c (%) levels from baseline to 24 weeks was a secondary endpoint in the extended study. Proportions of patients achieving the HbA1c target, changes in fasting and postprandial glucose levels, and safety endpoints were also evaluated. Between-group comparisons were performed between the add-on and initial combination groups.

In the 1596 patients of the effectiveness set, the mean changes in HbA1c levels at 12 weeks were -0.8% ± 1.2%, -0.3% ± 0.8% and -1.9% ± 1.4% for the evogliptin add-on, evogliptin-switching and initial combination groups, respectively. Among the 1920 patients in the safety set, 23 experienced adverse drug reactions, and there was no significant difference among the three groups.

Evogliptin reduces blood glucose levels and is well-tolerated when used as an add-on, as a switch from other dipeptidyl peptidase 4 inhibitors, or as part of an initial combination therapy in patients with type 2 diabetes mellitus.
