Popis: Introduction Dipeptidyl peptidase-4 (DPP-4) inhibitors are an established treatment in type 2 diabetes mellitus (T2DM). The objective of this study was to investigate differences in quality of life (QOL) and treatment satisfaction among treatment-naïve T2DM patients receiving once-weekly trelagliptin or a daily DPP-4 inhibitor. Methods In this multicenter, randomized, open-label, parallel-group, phase IV study conducted in Japan, 218 patients were randomized to trelagliptin 100 mg once weekly or a once- or twice-daily DPP-4 inhibitor for 12 weeks (NCT03014479; JapicCTI-173482). QOL and treatment satisfaction were assessed using the Diabetes Therapy-Related QOL (DTR-QOL) Questionnaire and Diabetes Treatment Satisfaction Questionnaire (DTSQ), respectively. The primary endpoint was change from baseline in DTR-QOL total score at week 12. Secondary endpoints included further analysis of the DTR-QOL and DTSQ components. Other endpoints included glycemic control, treatment adherence, and safety. Results The between-group difference in the change from baseline to week 12 in DTR-QOL total score was 2.418 (95% confidence interval − 1.546, 6.382; P = 0.2305). Analysis of the DTR-QOL and DTSQ results by subscales and stratification generally showed a numerical improvement with trelagliptin over daily DPP-4 inhibitors. QOL and treatment satisfaction improved with a reduction in frequency of concurrent and study drug dosing. Treatment adherence was > 97% for both groups. The effect of trelagliptin on glycemic control was similar to that seen with daily DPP-4 inhibitors. Trelagliptin and daily DPP-4 inhibitors were well-tolerated and demonstrated similar safety profiles. Conclusions Once-weekly trelagliptin 100 mg administered for 12 weeks resulted in a numerically, but not statistically, greater improvement in QOL and treatment satisfaction versus daily DPP-4 inhibitors. The decision to administer once-weekly or daily DPP-4 inhibitor treatment is likely to depend on patient preferences and the treatment policies of physicians.
