Efficacy and safety of once-weekly oral trelagliptin switched from once-daily dipeptidyl peptidase-4 inhibitor in patients with type 2 diabetes mellitus: An open-label, phase 3 exploratory study.

ABSTRACT: Trelagliptin, a novel once-weekly oral dipeptidyl peptidase-4 (DPP-4) inhibitor, has shown favorable efficacy and safety in type 2 diabetes mellitus patients. Trelagliptin was launched in Japan, and is expected to be initially used for switchover from a daily DPP-4 inhibitor in the clinical setting. Thus, the present study was carried out to explore the efficacy and safety of trelagliptin after a daily DPP-4 inhibitor was switched to it.This was an open-label, phase 3 exploratory study to evaluate the efficacy and safety of trelagliptin in Japanese type 2 diabetes mellitus patients who had stable glycemic control on once-daily sitagliptin therapy. Eligible patients received trelagliptin 100 mg orally before breakfast once a week for 12 weeks. The primary end-point was blood glucose by the meal tolerance test, and additional end-points were glycemic control (efficacy) and safety.Altogether, 14 patients received the study drug. The blood glucose did not markedly change from baseline at major assessment points in the meal tolerance test, and a decrease in blood glucose was observed at several other assessment points. Adverse events were reported in 42.9% (6/14) of patients, but all adverse events were mild or moderate in severity, and most were not related to the study drug. No cases of death, serious adverse events or hypoglycemia were reported.It is considered possible to switch a once-daily DPP-4 inhibitor to trelagliptin in type 2 diabetes mellitus patients with stable glycemic control in combination with diet and exercise therapy without any major influences on glycemic control or safety.

Project description:IntroductionDipeptidyl 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.MethodsIn 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.ResultsThe 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.ConclusionsOnce-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.Trial registrationClinicalTrials.gov (NCT03014479) and JAPIC (JapicCTI-173482).FundingTakeda Pharmaceutical Company Ltd.

Project description:IntroductionLong-term effectiveness and durability of glucose-lowering medications are important considerations in managing type 2 diabetes (T2D). This study aimed to compare durability of treatment efficacy of once-weekly (OW) semaglutide for T2D with that of the dipeptidyl peptidase 4 inhibitor (DPP-4i) class.MethodsThis observational cohort study used 2017-2022 data from the Optum® Clinformatics® Data Mart to compare long-term clinical outcomes associated with semaglutide or DPP-4i in US adults with T2D. The primary outcomes were HbA1c at 2-year follow-up, change in HbA1c from baseline, and the odds of achieving HbA1c targets. BMI at 2-year follow-up, change in BMI from baseline, odds of reducing BMI category, and the need for treatment augmentation were exploratory outcomes. Bivariate and multivariate analyses were conducted using inverse probability of treatment weighting (IPTW) weighted descriptive statistics.ResultsWeighted HbA1c and BMI cohorts included 865 and 642 semaglutide users and 779 and 537 DPP-4i users, respectively. In the weighted HbA1c cohort, semaglutide and DPP-4i users had an average age of 60 years and similar baseline characteristics including HbA1c level and comorbidity status. Two-year follow-up HbA1c with semaglutide was 0.56% lower than with DPP-4i; reduction in HbA1c from baseline was 0.61% greater. Odds of achieving HbA1c level < 7% were 2.16 times greater after covariate adjustment (all, p < 0.001). Semaglutide was associated with 1.03 kg/m2 greater reduction in BMI and 2.27 times greater odds of reducing BMI category vs DPP-4i (p < 0.001). Semaglutide users were less likely to add new glucose-lowering treatment (hazard ratio [HR] 0.57; p < 0.001) or initiate insulin (HR 0.49; p < 0.001) vs DPP-4i users.ConclusionCompared with DPP-4i, semaglutide was associated with lower follow-up HbA1c and BMI, greater reduction in HbA1c and BMI from baseline, and reduced likelihood of requiring treatment augmentation or insulin initiation to manage T2D in US adults, suggesting better durability of semaglutide vs DPP-4i.
